Chapter 5 – States of Consciousness 1. Consciousness is the awareness of internal and external events being experienced at a given moment. 2. Waking consciousness: Normal awareness of yourself and your surroundings. Altered states: Changes in awareness, such as dreaming, meditation, hypnosis, or drug effects. 3. Altered states occur through: Sleep and dreaming Meditation and hypnosis Psychoactive drugs Sensory deprivation Fatigue 4. Stages of sleep: NREM 1: Light sleep; easily awakened. NREM 2: Deeper sleep; heart rate and body temperature decrease. NREM 3: Deep sleep; body restoration. REM: Vivid dreams, active brain, temporary muscle paralysis. 5. About how long does a complete cycle of sleep take? 90 minutes 6. Sleep deprivation results in permanent negative effects. False. Many effects improve with adequate sleep, although prolonged sleep deprivation can cause serious problems. 7. Forgetting is an important human function. True. It helps prevent information overload. 8. Night terrors happen during deep sleep and are often not remembered; nightmares are frightening dreams that are usually remembered. 9. Staying up all night studying is a good idea. False. Sleep helps memory and learning. 10. Why do humans sleep? To restore the body, conserve energy, support brain function, and strengthen memories. 11. Three main theories of dreaming: Wish-fulfillment theory Information-processing theory Physiological-function theory 12. Latent content; manifest content. 13. Insomnia 14. Sleep apnea 15. Circadian rhythms 16. Meditation is a learned technique for relaxation and focused attention that brings about an altered state of consciousness. Long-term practice can improve health. 17. Drug categories: Psychoactive drugs: Drugs that affect consciousness, mood, perception, or behavior. Addictive drugs: Drugs that can lead to compulsive use. Stimulants: Drugs that increase nervous system activity. Depressants: Drugs that slow nervous system activity. Narcotics: Drugs, especially opioids, that relieve pain. Hallucinogens: Drugs that alter perception and sensory experiences. 18. Alcohol is safer than other drugs. False 19. Drug dependence is best explained by personality and willpower. False 20. Psychedelic drugs. Chapter 6 – Learning 1. Learning is a relatively permanent change in behavior brought about by experience. 2. Two types of conditioning: Classical conditioning — Ivan Pavlov: Learning by associating two stimuli. Operant conditioning — B. F. Skinner: Learning through consequences. 3. Matching: D — A once-neutral stimulus paired with an unconditioned stimulus. B — Naturally brings about a response. A — A stimulus that initially does not bring about the response. E — A response that follows a previously neutral stimulus after conditioning. C — A reflexive response that needs no training. 4. Conditioned = learned Unconditioned = unlearned or natural 5. Previously neutral stimulus becomes the conditioned stimulus. 6. Pavlov’s experiment: Pavlov rang a bell before giving dogs food. After repeated pairings, the dogs salivated at the sound of the bell alone. 7. Variables: Before conditioning Neutral stimulus: Bell → Neutral response: No salivation Unconditioned stimulus: Food → Unconditioned response: Salivation During conditioning - Neutral stimulus: Bell + Unconditioned stimulus: Food → Unconditioned response: Salivation After conditioning - Conditioned stimulus: Bell → Conditioned response: Salivation 8. Extinction 9. Spontaneous recovery 10. Generalization vs. discrimination: Generalization: Responding similarly to similar stimuli; example: salivating to similar tones. Discrimination: Responding differently to distinct stimuli; example: salivating only to the specific tone associated with food. 11. Dopamine 12. Classical or operant: Voluntary behaviors: Operant Involuntary behaviors: Classical Ivan Pavlov: Classical B. F. Skinner: Operant Dogs salivating at a bell: Classical Rats pressing a lever for food: Operant 13. In operant conditioning, learning happens when a voluntary response is reinforced or punished by its consequences. 14. An organism’s behavior and its environment. 15. True or False: True — Responses leading to satisfying consequences are more likely to be repeated. False — Environment has little influence on behavior. False — Conditioning cannot be applied to humans. False — Positive and negative mean good and bad. 16. Thorndike’s law of effect. 17. Matching: Positive: Addition of a stimulus Negative: Removal of a stimulus Reinforcement: Leads to an increase in behavior Punishment: Leads to a decrease in behavior 18. Definitions and examples: Positive reinforcement: Adding something desirable to increase behavior; getting paid for working. Negative reinforcement: Removing something unpleasant to increase behavior; buckling a seat belt to stop a warning beep. Positive punishment: Adding something unpleasant to decrease behavior; receiving extra chores for breaking a rule. Negative punishment: Removing something desirable to decrease behavior; losing video game privileges. 19. Reinforcement schedules: D — Reinforcer delivered every 5 minutes. B — Reinforcer after every 5 responses. E — Reinforcer after an unknown or changing amount of time. C — Reinforcer after an unknown or changing number of responses. A — Reinforcer every time the behavior occurs. 20. Ratio schedules depend on: Number of responses 21. Interval schedules depend on: Amount of time 22. Fixed vs. variable: Fixed schedules are predictable; variable schedules change. 23. Shaping Example: Teaching a dog to roll over by rewarding each step toward the behavior. 24. Cognitive learning theory. 25. Latent learning; a new behavior is not demonstrated until there is a reason or motivation to use what was learned. 26. Cognitive map 27. A mental map of my school, home, and familiar roads. 28. Observing; observational learning; Bobo doll experiment. 29. Mirror neurons Chapter 7 – Memory 1. Memory is the process by which we encode, store, and retrieve information. 2. Three basic memory processes: Encoding: Taking in information. Storage: Keeping information over time. Retrieval: Accessing stored information. 3. Sensory memory → Short-term memory → Long-term memory. 4. Matching: C — Holds information while actively manipulating or rehearsing it. A — Briefly holds incoming sensory information. B — Holds information for around 15–25 seconds. D — Stores information relatively permanently. 5. Rehearsal keeps information active and helps it enter long-term memory. Elaborative rehearsal connects information to meaning and prior knowledge, while simple rehearsal repeats it. 6. Types of long-term memory: Lafayette is in Louisiana: Semantic First week of college: Episodic Riding a bicycle: Procedural 7. Explicit (declarative) memory. 8. Retrieval failure 9. Recall vs. recognition: Recall: Remembering an answer without choices, such as a fill-in-the-blank question. Recognition: Identifying an answer among choices, such as a multiple-choice question. Chapter 8 – Cognition and Language 1. Cognition 2. Concepts; a prototype is the most typical example of a concept. 3. Category: Furniture. Prototype: Chair Less typical member: Beanbag chair 4. Deductive reasoning moves from general principles to specific conclusions. Inductive reasoning moves from specific observations to general conclusions. Examples: Deductive: All humans need sleep. I am human, so I need sleep. Inductive: Several students who study regularly earn good grades, so studying may help students earn good grades. 5. Matching: A — A strategy that guarantees a solution. B — A mental shortcut that can lead to errors. C — Judging likelihood by how easily examples come to mind. D — Preferring an option because it is familiar. E — Giving more weight to outcomes closer to the present. 6. Confirmation bias 7. Problem-solving steps: Identify and define the problem. Develop and evaluate possible solutions. Implement a solution and evaluate the results. 8. Well-defined vs. ill-defined: Well-defined: Clear goal and rules; example: solving a math equation. Ill-defined: Unclear goal or multiple solutions; example: choosing a career. 9. Subgoaling 10. Functional fixedness 11. Convergent thinking narrows ideas to one correct answer. Divergent thinking generates many possible ideas. 12. Example of insight: Realizing you can stand on a chair to reach a high shelf. It depends on reorganizing your understanding of a problem. 13. Language is communication through symbols arranged according to systematic rules. 14. Nativist approach; language acquisition device (LAD). 15. Interactionist approach; biological predispositions and environmental circumstances. Final reflection These last answers are personal, so change them if they don't describe you. How prepared do you feel? 3 Three concepts most confident in: Classical conditioning Types of memory Reinforcement and punishment Three concepts least confident in: Stages of sleep Reinforcement schedules Reasoning and problem solving How will you strengthen your understanding? I plan to review my study guide, practice questions, and spend more time on the concepts I don't understand.

# JUPEB WEEK 1: INTEGRATED MASTER PLAN ## ⚡ PHYSICS: Physical Quantities, Dimensions & Vectors ### Core Definitions - Fundamental Quantities: Independent primary metrics (Mass $M$, Length $L$, Time $T$, Temperature $\theta$, Current $I$). - Dimensional Homogeneity: Structural rule stating all terms in an equation must possess matching base units. - Vector vs Scalar: Vectors contain absolute magnitude and directional alignment; scalars express magnitude exclusively. ### Key Formulas - Force Equation Dimensions: $[Force]=M^1L^1T^{-2}$ - Vector Dot Scalar Product: $\vec{A}\cdot\vec{B}=AB\cos\theta$ - Vector Cross Product Magnitude: $|\vec{A}\times\vec{B}|=AB\sin\theta$ ### 25-Mark Theory Essay Practice - Q: Define the principle of dimensional homogeneity and evaluate whether the kinematic function $v^2=u^2+2as$ is dimensionally stable. - Model Points: 1. Define the homogeneity principle clearly. 2. Evaluate left-hand side: $[v^2]=(L^1T^{-1})^2=L^2T^{-2}$. 3. Evaluate right-hand side components: $[u^2]=L^2T^{-2}$ and $[2as]=1\cdot(L^1T^{-2})\cdot(L^1)=L^2T^{-2}$. 4. Compare all terms to confirm matching dimensional arrays ($L^2T^{-2}$), validating structural consistency. --- ## 🧪 CHEMISTRY: Data Measurements, Atomic Structure & Layouts ### Core Definitions - Relative Atomic Mass ($A_r$): Calculated average atomic mass evaluated against $\frac{1}{12}$ of a stable $^{12}C$ isotope. - Orbital Mechanics Rules: Aufbau states lowest energy configurations fill first; Pauli forbids matching quantum states; Hund requires half-filling subshells before pairing. - Measurement Variances: Systematic variations alter accuracy in single directions; random variations alter precision unpredictably. ### Key Electron Configuration Structures - Hydrogen ($H$): $1s^1$ - Carbon ($C$): $1s^2 2s^2 2p^2$ - Oxygen ($O$): $1s^2 2s^2 2p^4$ ### 25-Mark Theory Essay Practice - Q: Describe the four quantum integers ($n,l,m,s$) utilizing electronic energy distributions to account for chromium's exceptional configuration stability. - Model Points: 1. State $n$ (principal energy level), $l$ (orbital subshell shape), $m$ (spatial orientation), and $s$ (spin orientation). 2. Express standard chromium configuration: $[Ar]3d^5 4s^1$. 3. Detail how the symmetric, half-filled $3d^5$ subshell maximizes exchange stability over an un-stabilized $3d^4 4s^2$ layout. --- ## 🧬 BIOLOGY: Scientific Inquiries & Introduction to Biomolecules ### Core Definitions - Scientific Methodology: Empirical loop consisting of Observation $\rightarrow$ Questioning $\rightarrow$ Hypothesis Formulation $\rightarrow$ Empirical Testing $\rightarrow$ Analytical Conclusion. - Condensation Reaction: Synthesis mechanism pairing molecular structures while dropping $H_2O$ units. - Hydrolysis Reaction: Cleavage mechanism splitting polymer chains by introducing reactive $H_2O$ units. ### Structural Biomolecule Frameworks - Monosaccharides: Structural base $(CH_2O)_n$ linking into polysaccharides via glycosidic bridges. - Amino Acids: Built from a central carbon bonded to an amino group ($-NH_2$), a carboxyl group ($-COOH$), and variable side-chains ($-R$). ### 25-Mark Theory Essay Practice - Q: Detail the structured execution of a controlled biological experiment, explaining the role of a null hypothesis ($H_0$) in validating results. - Model Points: 1. Isolate the independent experimental variable while binding all other background constants. 2. Detail quantitative data logging to counter observational bias. 3. Define $H_0$ as a baseline assumption asserting no actual variations exist between test subjects. 4. Use statistics to reject or fail to reject $H_0$, verifying if observed variances stem from variables or simple chance.

Psychology: Development Across the Life Span Study notes 1. Developmental psychology (slides 2–11) Developmental psychology: The study of how people change from conception until death. Three domains of development: Physical: Changes in the brain and body. Cognitive: Changes in thinking, learning and memory. Socio-emotional: Changes in emotions and relationships. Important terms Term What to remember Teratogens Substances that harm prenatal development Fetal alcohol syndrome (FAS) A serious condition caused by prenatal alcohol exposure Maturation Natural physical development that makes new abilities possible Synapses Connections where neurons communicate Myelination Insulation of axons that improves neural signaling Brain development: Positive environments, stimulation and caregiver contact support healthy brain development. Poverty, toxins, stress and poor nutrition can negatively affect development. Exam example: A baby gradually develops the physical ability to sit, crawl and walk. Answer: Maturation. 2. Attachment theory (slides 12–17) Harlow's experiment Baby monkeys were given two artificial mothers: A wire mother that provided milk. A soft cloth mother that provided comfort. The monkeys preferred the cloth mother and approached the wire mother mainly for food. Conclusion: Attachment involves comfort and security, not just food. Ainsworth's three attachment styles Style Behavior Secure Upset when caregiver leaves; comforted when they return Avoidant Avoids or ignores the caregiver Ambivalent Seeks comfort but also resists it Separation anxiety: Distress when separated from a caregiver. Exam example from your slides: Ian cries for attention. When his mother eventually picks him up, he hugs her but continues crying and pushes his toy away. Answer: Ambivalent attachment. 3. Piaget's cognitive development (slides 22–32) This is a section I'd spend extra time studying because it includes several theories and concepts that can appear in scenario questions. Schemas: Mental frameworks used to understand the world. Assimilation: Adding new information to an existing schema. Accommodation: Changing an existing schema to fit new information. Example: A child calls every four-legged animal a dog. That's assimilation. The child learns that cats are different from dogs and changes their understanding. That's accommodation. Piaget's four stages Four stages to memorize Age ranges follow your professor's slides. Sensorimotor: Birth–2 years Babies learn through their senses and movements. Key concept: Object permanence — knowing an object still exists when hidden. Preoperational: 2–7 years Children use symbols and imagination but struggle with logical reasoning. Key concepts: Egocentrism, symbolic play and difficulty understanding conservation. Concrete operational: 7–12 years Children develop logical thinking about concrete situations. Key concepts: Conservation, rules and improved mathematical reasoning. Formal operational: 12 years–adulthood People develop abstract thinking and can formulate and test hypotheses. Other important definitions Object permanence: Knowing something exists even when you can't see it. Egocentrism: Difficulty understanding another person's perspective. Conservation: Understanding that quantity remains the same even when appearance changes. Symbolic play: Pretending one object represents something else. Piaget's limitation: He underestimated how early some cognitive abilities develop. Modern psychologists often view development as more gradual. 4. Adolescent development (slides 34–38) Adolescence: Approximately ages 11–21, according to your slides. Important brain regions: Limbic system: Involved in motivation and emotions. Frontal cortex: Important for planning, judgment and decision-making. During adolescence, emotional and motivational systems can be particularly active while the frontal cortex continues developing. Factors influencing identity Culture Gender Personal characteristics Friends and peers Parenting Four parenting styles Style Definition Authoritarian Strict rules, low responsiveness Authoritative Clear rules, high responsiveness Permissive Few rules, high responsiveness Neglectful Few rules, low responsiveness Remember the difference between authoritarian and authoritative. They sound similar but represent different parenting approaches. 5. Erikson's psychosocial theory (slides 18–20, 38–40) Erikson proposed eight stages of psychosocial development. Each involves a developmental conflict. Your slides emphasize identity formation during adolescence and three challenges in later life. For your notes, learn all eight stages. Stage Conflict Infancy Trust vs. mistrust Toddlerhood Autonomy vs. shame and doubt Preschool Initiative vs. guilt Childhood Industry vs. inferiority Adolescence Identity vs. role confusion Young adulthood Intimacy vs. isolation Middle adulthood Generativity vs. stagnation Late adulthood Integrity vs. despair Four concepts to understand especially well: Identity vs. role confusion: Discovering who you are. Intimacy vs. isolation: Developing close relationships. Generativity vs. stagnation: Contributing to future generations. Integrity vs. despair: Reflecting on your life with satisfaction or regret. Exam example: Nathan joins several different social groups during high school while figuring out who he is. Answer: Identity vs. role confusion. 6. Kohlberg's moral development (slides 41–47) Kohlberg studied how people reason about right and wrong. Three levels of moral reasoning Preconventional Morality is based on punishment, rewards and self-interest. Example: "I won't steal because I might get caught." Conventional Morality is based on laws, social rules and other people's approval. Example: "I won't steal because stealing is against the law." Postconventional Morality is based on broader ethical principles and human rights. Example: "An unjust law may need to be challenged to protect human rights." Heinz dilemma: A man must decide whether to steal expensive medicine to save his dying wife. Kohlberg was interested in the reasoning behind a person's decision, not simply whether they answered yes or no. Exam examples from your slides Jan fears punishment for an unpaid textbook: Preconventional. Kyle leaves a note after damaging a car because the law requires it: Conventional. A protester breaks curfew to oppose racial injustice based on broader ethical principles: Postconventional. What to put on your exam index card Your professor may allow a limited amount of space, so prioritize concepts that are easy to confuse and useful for scenario questions. Index card notes Copy DEVELOPMENT Physical = body | Cognitive = thinking | Socio-emotional = relationships Teratogens = harm fetus | FAS = prenatal alcohol exposure | Maturation = natural physical development ATTACHMENT Harlow: Comfort over food Secure = accepts comfort | Avoidant = avoids caregiver | Ambivalent = seeks + resists comfort PIAGET Assimilation = use old schema | Accommodation = change schema Sensorimotor (0–2) = senses, object permanence Preoperational (2–7) = symbols, egocentrism, struggles with conservation Concrete (7–12) = logic, conservation Formal (12+) = abstract thinking, hypotheses ADOLESCENCE Limbic = emotion | Frontal = judgment Authoritarian = strict/low warmth | Authoritative = strict/high warmth Permissive = few rules/high warmth | Neglectful = few rules/low warmth ERIKSON Trust → Autonomy → Initiative → Industry → Identity → Intimacy → Generativity → Integrity KOHLBERG Preconventional = punishment/reward Conventional = laws/approval Postconventional = ethical principles Check your professor's rules for index-card size and whether both sides are allowed. This is a condensed reference, not a replacement for studying. How to study these notes without repeating your last exam Tonight, start with attachment and Piaget. Read each section, cover your notes and explain the concepts out loud. Then answer your professor's example questions without looking. Tomorrow, study Erikson and Kohlberg the same way. Review adolescent and prenatal development afterward. For every concept, aim to do three things: define it, give an example and recognize it in a scenario. Most importantly, don't just reread this study guide. Your professor's slides contain eight scenario-based practice questions. Answer all eight without your notes, then explain why each correct answer fits. That's your first practice test

Absolutely 💗 I made this directly from the Unit 1 Review video. The biggest thing your teacher says at the end is that the test won’t just ask you to memorize definitions — you need to be able to apply the concepts to new situations and explain your reasoning using evidence. 🧬 BIOLOGY UNIT 1 TEST STUDY GUIDE 1. 🔬 Scientific Thinking & Experimental Design Know the difference: Observation * Something you directly see, measure, or notice. * Example: The plant grew 4 cm. Inference * A conclusion/explanation based on observations and evidence. * Example: The plant grew because it received more sunlight. Hypothesis * A testable prediction. * Usually written as: If ___, then ___, because ___. Variables Independent variable * What the scientist changes. Dependent variable * What the scientist measures. ⭐ Easy way to remember: Independent = I change it. Dependent = Data I collect. Control group * Used as a comparison. * It helps scientists see whether the independent variable actually caused a difference. Constants * Things that are kept the same during an experiment. Fair test A good experiment should change one main variable while keeping other important conditions controlled. Experimental evidence You need to be able to decide whether results: * Support the hypothesis * Do not support the hypothesis ⚠️ Don’t automatically say a hypothesis was “proven.” Scientists use evidence to determine whether results support it. Repeated trials Scientists repeat experiments and collect multiple measurements because one trial may not be reliable. Sources of error Be able to identify things that could have affected an investigation, such as: * Something not being kept constant * Measuring incorrectly * Equipment problems * Human error * Not enough trials ⸻ 📊 2. Working With Data Your teacher specifically says you need to be able to: Read: * Tables * Graphs * Diagrams * Written scenarios Identify patterns and trends Look for things like: * Increasing * Decreasing * Staying the same * One group being higher/lower than another Compare groups Use actual evidence from the data. ❌ Weak: Group A did better. ✅ Better: Group A had a higher growth rate than Group B. Make predictions Use the pattern in the data to predict what could happen next. Result vs. Conclusion Result = WHAT happened Conclusion = WHAT the results mean Example: Result: Plants receiving more light grew 5 cm taller. Conclusion: The data suggests that greater light exposure increased plant growth. ⸻ 🌱 3. Characteristics of Living Things You need to understand what separates living things from nonliving things. Living things have characteristics such as: 🧫 Cells Living things are made of cells. ⚡ Energy Living things need and use energy. 🌱 Growth & development Living things grow and change throughout their lives. 🧬 Reproduction Living things can produce new organisms. 👀 Response Living things respond to changes in their environment. ⚖️ Maintaining internal conditions Living things maintain stable internal conditions. This is called homeostasis. Evidence questions You may be given an unfamiliar example and asked: Is it living or did it come from something living? Don’t just guess based on whether it moves. Look at the evidence and the characteristics of life. ⸻ 🔬 4. Microscopes & Cellular Observation Your teacher says you need to understand: Purpose of a microscope A microscope allows scientists to observe biological structures that are too small to see with the naked eye. Magnification Magnification makes something appear larger. You need to understand how changing magnification affects what you see. Generally: ⬆️ Higher magnification * Object appears larger * You see a smaller area * You may see more detail ⬇️ Lower magnification * Object appears smaller * You see a larger area Evidence from microscopes Scientists can use observations made with microscopes as evidence. Microscope parts Your video says you should be able to identify microscope parts and know their functions, so make sure you know the parts your class used, especially: * Eyepiece/ocular lens * Objective lenses * Stage * Light source * Diaphragm * Coarse adjustment * Fine adjustment ⸻ ⚛️ 5. Chemistry of Life The atom Know the basic structure of an atom and the roles of its particles: Particle Charge Proton + Neutron 0 Electron − Chemical bonds Atoms can interact with each other and form chemical bonds. You need to understand how atoms interact to form bonds, not just memorize the word “bond.” ⸻ 🖤 6. Why Carbon Is Important Your review specifically says you need to understand: Why carbon is especially important in living organisms. Carbon is important because it can form many different bonds and build the large, complex molecules needed by living things. Structure → Function This is a BIG idea. The structure of a molecule affects its function. In other words: What something looks like/is built like → affects what it can do. You should be able to apply this idea to unfamiliar examples. ⸻ 🧬 7. Biological Molecules Know the four major types of biological molecules and their general roles: 🍞 Carbohydrates Generally used for: * Quick/short-term energy * Some structural purposes 🥑 Lipids Generally used for: * Long-term energy storage * Cell membranes * Insulation/protection 💪 Proteins Used for many jobs, including: * Structure * Transport * Movement * Enzymes 🧬 Nucleic acids Used to: * Store and transmit genetic information ⭐ Remember: Carbs → energy Lipids → long-term energy/storage & membranes Proteins → many jobs, including enzymes Nucleic acids → genetic information ⸻ 🧪 8. ENZYMES ⭐ VERY IMPORTANT Your video has a whole section on enzymes, so definitely study this. What do enzymes do? Enzymes help biological chemical reactions happen more efficiently. They are biological catalysts. Enzyme + substrate An enzyme interacts with the substance it acts on, called the substrate. The substrate interacts with the enzyme’s active site. Think: Enzyme → active site → substrate Structure & function The shape/structure of an enzyme is important because it affects how it interacts with its substrate. That’s another example of: Structure → function Conditions affect enzymes Changes in environmental conditions can affect enzyme activity. For example: * Temperature * pH You need to be able to look at an enzyme investigation and interpret what happened. ⸻ 🌡️ 9. pH & Biological Systems pH scale The pH scale tells you how acidic or basic something is. Remember: 🔴 Low pH → acidic ⚪ pH 7 → neutral 🔵 High pH → basic Why does pH matter? Changes in pH can affect biological processes. This is especially important with enzymes, because changing the conditions can change enzyme activity. Test-style question You might see an experiment where an enzyme is tested at different pH levels. You should be able to: 1. Identify what was changed. 2. Look at the data. 3. Identify the pattern. 4. Explain what happened. 5. Use evidence from the data to support your conclusion. ⸻ 🚨 WHAT YOUR TEACHER REALLY WANTS YOU TO KNOW The last part of your video is SUPER important. It basically says: Don’t just memorize definitions. You need to be able to take what you know and use it in a new situation. For example, they might NOT ask: What is an independent variable? Instead, they could give you an experiment and ask: Which variable is the independent variable? You have to figure it out from the situation. ⸻ ⭐ THE BIG 10 TO KNOW BEFORE THE TEST If you’re short on time, make sure you can answer these: 1. What’s the difference between an observation and an inference? 2. What makes a hypothesis testable? 3. What’s the independent variable vs. dependent variable? 4. Why do scientists use controls, constants, and repeated trials? 5. How do you use data to support a conclusion? 6. What characteristics make something living? 7. How does changing microscope magnification affect what you see? 8. What are the four major biological molecules and their general jobs? 9. How do enzymes interact with substrates, and how can conditions affect enzyme activity? 10. What does pH tell you, and how can changing pH affect biological processes? 🧠 One sentence to remember the whole unit: Scientists use experiments → collect data → find patterns → make conclusions about how living systems work. And honestly, based on the video, #1, #2, #3, #4, #5, enzymes, and pH are the areas I’d focus on the most because the review repeatedly emphasizes applying those ideas to investigations rather than simply memorizing vocabulary.
