Tough A words

Ethics: The study of morality and the difference between right and wrong. Epistemology: The study and theory of knowledge. Metaphysics: The purpose of why things exist. What must be fulfilled? Why do we exist? Pre-Socrates: The very first thinkers in Western philosophy, active in ancient Greece during the 6th and 5th centuries BCE. They are called "Pre-Socratic" because they lived and wrote before Socrates. Thales: Water was the fundamental substance for all life. Anaximander: First to make a map Pythagoras: The father of mathematics Heraclitus: Fundamental substance was fire. He believed everything changes. Permenides: Believed everything did not change. Socrates Plato (Forms) Aristotle (The Observer) Came up with the cave theory. The Physical Realm: The world we see and touch. Everything here is temporary, constantly changing, and flawed. The Realm of Forms: An invisible, unchanging world where the perfect, ideal versions of everything exist. Women possess the same mental capacities as men and should be allowed to rule, he also consistently referred to women as the "weaker" sex. (The soul has no gender) Head/Reasoning: This is the seat of reason, logic, and intellect. It seeks the ultimate truth, makes calculated decisions, and distinguishes between what is real and what is an illusion. The Chest/Spirit: this is the seat of emotion, courage, pride, and willpower. It is the part of you that gets angry at injustice, drives you to overcome challenges, and seeks honor or social recognition. The Abdomen/Appetite: This is the seat of basic physical desires and instincts. It drives cravings for food, drink, sex, wealth, and material comforts. It is purely driven by pleasure and lacks any logical restraint. Hylomorphism (the theory that everything is a mix of matter and form). 1. Material cause, or the elements out of which an object is created; 2. Efficient cause, or the means by which it is created; 3. Formal cause, or the expression of what it is; 4. Final cause, or the end for which it is. He argued that knowledge must come from sensory experience and careful observation, not just pure meditation. Rationalism vs Empiricism (How do we know things) Rationalism (Plato) Empiricism The intellect, logic, and deductive reasoning. Rationalists believe humans are born with "innate ideas"—built-in concepts, truths, or structures inside the mind that we don't need to learn from the outside world (e.g., mathematical truths, the concept of God, or basic laws of logic). Empiricists argue that the ultimate source of all knowledge is sensory experience—what we can see, hear, touch, taste, and smell. They believe that if you cannot observe or measure something, you cannot truly know it. Logic for reasoning Deductive Reasoning Inductive reasoning Deductive reasoning starts with a general statement, theory, or universal rule and narrows it down to a specific conclusion. If your initial rules are true, your conclusion must be true.🔺 Inductive reasoning starts with specific observations or data points and broadens them out to form a general rule or theory. 🔻 Fallicies Ad Hominem: Attacking the opponent’s character, looks, or personality instead of their argument. Straw Man: Misrepresenting, exaggerating, or oversimplifying an opponent’s argument to make it easier to attack. Bandwagon Appeal (Ad Populum): Arguing that something must be true, right, or good simply because a large number of people believe it. Non Sequitur: (A statement that does not logically follow from what preceded it; a conclusion that does not follow from the premises.): “Person ‘A’ is incredibly athletic. Her siblings must be very athletic as well.” Appeal to tradition: If it's a tradition, then it must be true. Appeal to popularity: When someone argues that a claim must be true, right, or good simply because a large number of people believe it or do it. Groupthink is when a group of people makes really bad decisions because everyone cares more about fitting in and keeping the peace than finding the actual truth. Instead of thinking for themselves, people just go along with what the group leader or the majority says. Consequentialism says that an action is good if it brings about a good result. The action itself isn't good or bad; you have to wait and see how it turns out. "The ends justify the means." Non-Consequentialism (also called Deontology) says that some actions are just inherently right or wrong, no matter what the outcome is. You have a duty to follow moral rules. Carl Rogers defined a fully functioning person as someone who is completely in touch with their true desires and feelings, and is actively working to reach their full potential

1. Cell Transport Brownian Movement Definition: Random movement of particles caused by their inherent kinetic energy. Occurs above freezing temperatures. Passive process (requires no energy/ATP). Responsible for constant molecular motion. Diffusion Definition: Movement of molecules or ions from an area of higher concentration to lower concentration. Passive transport Moves down the concentration gradient No energy required Facilitated Diffusion Definition: Diffusion through a selectively permeable membrane using membrane proteins. Passive transport High → Low concentration Only certain substances can pass Filtration Definition: Movement of water and dissolved substances through a membrane from higher pressure to lower pressure. Driven by pressure differences Dialysis Definition: Separation of small molecules from larger molecules. Used in dialysis machines Not a normal transport process in the body 2. Active Transport Active Transport Definition: Transport requiring cellular energy (ATP). Endocytosis ("Into the Cell") Phagocytosis Cell Eating Engulfs solid particles Example: White blood cells engulfing bacteria Pinocytosis Cell Drinking Engulfs fluids Exocytosis Definition: Movement of substances out of the cell. 3.

Why Do We Touch Strangers So Much? A History Of The Handshake Offers Clues - Reading - 7/14

Tough cases

​​2023 Semester Only Grade 7th/8th Physical Education Content Review Key Concepts Content • Responsible behaviors • Team Building • Responsible Behaviors o Demonstrate acceptance and respect for people with diverse backgrounds and abilities during fitness activities. Develop strategies for including everyone. o Demonstrate responsible behaviors during fitness activities. Examples of responsible behaviors are controlling emotions, resolving conflicts, respecting opponents and officials, and accepting both victory and defeat • Team Building o Characteristics of High-Performing Teams - Most members of high-performing teams report that it’s fun and satisfying to work on collaborative teams because they are asked to contribute at their highest potential and they learn a lot along the way. Characteristics of high-performing teams include the following: ▪ People have solid and deep trust in each other and in the team’s purpose — they feel free to express feelings and ideas. ▪ Everybody is working toward the same goals. Everyone places the team first. ▪ Team members are clear on how to work together and how to accomplish tasks. ▪ Everyone understands both team and individual performance goals and knows what is expected. ▪ Individuals contribute to the team based on their unique strengths ▪ The team engages in extensive discussion, and everyone gets a chance to contribute. ▪ Disagreement is viewed as a good thing and conflicts are managed. Criticism is constructive and is oriented toward problem solving and removing obstacles. ▪ The team makes decisions when there is natural agreement — in the cases where agreement is elusive, a decision is made by the team lead or executive sponsor, after which little second-guessing occurs. ▪ Each team member carries his or her own weight and respects the team processes and other members. ▪ The leadership of the team shifts from time to time, as appropriate, to drive results. ▪ No individual members are more important than the team. • Warm-up • Cool-Down • Heat Cramps • Hear Exhaustion • Heat Stroke • Dehydration • Proper Attire (clothes and shoes) - color and type of clothing to be worn during exercise in different climates • Proper Hydration - drink water before, during and after exercise especially during hot weather • Warm-up: Gentle exercises that get the heart and muscles ready for moderate to vigorous physical activity. You know when you are warmed up when you begin to sweat and breath more heavily. o Walking or jogging for 5-10 minutes is recommended • Cool-Down: Gentle exercises that let the body adjust to ending a workout. Should last for 5-10 minutes allowing your heart rate and breathing to return to normal. o Include light stretching in your cool down to help muscles relax and not feel stiff or sore afterward. • Heat-Related Illnesses o Heat Cramps: Painful, brief muscle cramps that occur during exercise in a hot environment, caused by dehydration o Heat Exhaustion: A heat illness caused by the body overheating. Symptoms include heavy sweating, dizziness, weakness and rapid pulse o Heat Stoke: A health illness caused by the bodies inability to regulate its temperature. Symptoms include hot, dry skin, elevated body temperature, lack of sweat, hallucinations o Dehydration: Excessive loss of body fluid • Aerobic exercise • Anaerobic exercise • Pedometer • Vigorous • Moderate • FITT • Aerobic Exercise - Rhythmic activity that uses large amounts of oxygen and works the heart and lungs. • Anaerobic Exercise - Activities performed (without oxygen) consists of brief strength-based activities. • Heart Rate - The number of times your heart beats per minute. • Moderate physical activity - An activity with intensity equal to brisk walking. Activities of moderate intensity can be performed for relatively long periods of time without fatigue. • Vigorous physical activity - Movement that expends more energy or is performed at a higher intensity than brisk walking. • Forehand stroke • Backhand stroke • Forehand strokes (racquet sports) are where the front of the hand leads the stroke. o To strike the ball players should stand with their opposite shoulder facing the net, swing from low to high and follow through. Opposite footsteps toward the net. o Follow through by driving the racket forward so that it ends up above the shoulders, pointing up to the sky and in the direction of the ball you just hit. o Hitting the ball too late may cause the ball to land out of bounds. • Backhand strokes (racquet sports) are where the back of the hand leads the stroke. o Begin with a balanced ready position. Transition from large steps to smaller steps as a player closes in on the ball will help maintain balance. Step toward the net with the foot on the same side. o As the ball approaches, the player must move to intercept it, the shoulder must turn to begin the backswing. As a player sets to hit the ball, the backswing is complete. o The path of the racket extends along the intended flight of the ball as long as possible. Contact point for a one-handed backhand is further in front of the body than in a two-handed stroke. o The face of the racket remains vertical through the contact zone. The follow through is high. • CPR • Aquatic safety • Cardiopulmonary Resuscitation (CPR) o Hands-Only CPR Steps: ▪ Call 911 and push hard and fast in the center of the chest (100 compressions a minute) • Aquatic Safety o Swim with a buddy o Take swimming, diving, and water safety or rescue classes to learn the skills to swim and dive safely. o Never swim under the influence of alcohol or drugs o Make sure to check the depth of the water before diving • Free Pass • Penalty try • Rugby Game Play: o free pass: is used to start the match or restart after a “try”. It starts from the center of the field at the halfway line at the beginning of each half. From the touch line (at the place where the ball went into touch) when the ball goes into touch (put into play), and from where the referee makes a mark when an infringement has taken place. o To score in flag rugby you must be on or cross the end zone with your flag on, touch the ball to the ground and say “try”. o A penalty try will be awarded if a try would have been scored if there was not foul play by the defending team. o When a try is scored, the game is restarted by a free pass from the center of the pitch by the non-scoring team. o The player taking the free pass must start with the ball in both hands and, when instructed by the referee who will declare “Play”, pass the ball sideways or backwards through the air to a team-mate. • Rules of the game • Basketball Rules: o The game starts with a jump ball then alternate possession begins. o Five players play on the floor at a time. Players’ positions consist of guards, forwards and a center, o Traveling- is having possession of the ball and moving without dribbling, resulting in a turnover. • Rules • Ultimate Frisbee is a non-contact field sport that combines elements of soccer, football and basketball. The object of the game is for a team to pass the disc from player to player until a pass is completed to a teammate in the end zone resulting in a score. Teams consist of 7 players. • How the Game is Played: o The game is played to 13 points or until a certain amount of time has passed. o All players from both teams begin each point in their respective end zones. Play is initiated with a “pull” from the defensive team’s end zone. The disc is passed from player to player down the field. o Once the disc is caught the “handler” must come to a complete stop. He/she may pivot but must maintain one planted foot at all times (even on the follow through). o The thrower or “handler” has ten seconds to throw the disc once caught. o A point is scored when a receiver catches the disc in the end zone. • Warm-up • Cool-Down • Heat Cramps • Heat Exhaustion • Heat Stroke • Dehydration • Proper Attire (clothes and shoes) - color and type of clothing to be worn during exercise in different climates • Proper Hydration - drink water before, during and after exercise especially during hot weather • Warm-up: Gentle exercises that get the heart and muscles ready for moderate to vigorous physical activity. You know when you are warmed up when you begin to sweat and breath more heavily. o Walking or jogging for 5-10 minutes is recommended • Cool-Down: Gentle exercises that let the body adjust to ending a workout. Should last for 5-10 minutes allowing your heart rate and breathing to return to normal. o Include light stretching in your cool down to help muscles relax and not feel stiff or sore afterward. • Heat-Related Illnesses o Heat Cramps: Painful, brief muscle cramps that occur during exercise in a hot environment, caused by dehydration o Heat Exhaustion: A heat illness caused by the body overheating. Symptoms include heavy sweating, dizziness, weakness and rapid pulse o Heat Stoke: A health illness caused by the bodies inability to regulate its temperature. Symptoms include hot, dry skin, elevated body temperature, lack of sweat, hallucinations • Dehydration: Excessive loss of body fluid • Alcohol • Smoking • Effective Communication • Alcohol o Underage drinking is considered illegal o There are laws about alcohol consumption o Alcohol slows down the ability to think clearly • Smoking o Smoking is the primary risk factor in respiratory diseases including emphysema and bronchitis o Cigarette smoking causes the heartbeat to increase the heart rate o Nicotine in cigarettes stimulates the heart to beat faster, which increases the heart’s need for more oxygen. Carbon monoxide replaces the oxygen in the blood forcing the heart to work harder. • Effective Communication o Includes: ▪ being respectful ▪ Actively listening ▪ Using assertive communication skills when needed • PACER • Push-ups • Curl-ups • Sit and Reach • Fitness Test o PACER: Performed to measure cardiorespiratory fitness o Push-ups: Use to measure muscular strength and endurance o Curl-ups: Used to measure abdominal muscular endurance and muscular strength o Sit and Reach: Performed to measure a student’s flexibility • Digital Citizenship • Digital Footprint • Digital Citizenship: is a safe, responsible, and respectful use of technology • Digital Footprint: is essentially a history of everything you’ve ever done online. Everything you post and do online can follow you through middle and high school, college, and even when you get a job. It has the potential to contribute positively or negatively to your digital reputation. • Positions in Hockey • How the Game is played • Scoring • Hand Placement • How the game of hockey is played o Street hockey is played very similar to ice hockey using the same rules and similar style of play. The only difference is that the players are using a ball instead of a puck and are running on firm ground rather than skating on ice. The game is played with 5 players and a goalie. There are five players on the court at a time with a goalie. Three forwards (2 wingers and a center) and two defenders. • Object of the game o Hockey is a fast-paced team sport, and the object is to outscore your opponent in the allotted time. • Start to play o A face-off will occur after every goal scored and to start off each period. The referee will drop the ball in-between the two centers who are facing each other. There are three periods in a game. • Out of Bounds o If the ball is hit out of bounds, then the opposing team may pass it back in from the side lines. • Scoring o a goal is made when a player either knocks down a cone, or if the ball crosses the goal line. Both goals and assists will be rewarded when scorekeeping during tournament play at the end of the unit. • How the game is played • Players and positions • Basic Skills • How the game of volleyball is played: o A game is played to 25 points. A team must win by 2 points and is called a set. A match is 3 out of 5 sets. o The server must stand anywhere behind the end line on his/her side of the court prior to the serve. The ball may be served underhand or overhand. The player who serves is in the right back position. o Each team may only hit the ball 3 times on its side before the ball must pass over the net. o The teams will rotate clockwise each time they win the serve. o A point is scored every time a ball is not returned properly into the opponent’s court, this is called rally scoring. Thus, both serving and receiving teams can score points. o If the ball hits the line it is considered, in bounds or good. • Players and Positions: o Setters – player who “sets” the ball with an “overhead pass” for a teammate to hit, the setter normally runs the offense o Hitter - the spiker or attacker o Outside hitter - A left or right-front attacker normally taking an approach which starts from outside the court o Libero - defensive specialists, designated for back row only, and wear a different colored jersey. The libero may serve for one player she is substituting for per game. o Blocking - A defensive play by one or more players meant to deflect a spiked ball back into the hitter’s court. To block, move your body in front of the hitter, keep arms in front, straight, palms facing the ball. • Players • Rules • Cues for throwing in flag football • Cues for catching • Scoring • Flag Safety • Defensive Strategy • Flag Football Players Include o Quarterback - The offensive person who is in charge of advancing the ball down the field (either by hand-off or pass), in order to gain yardage, a first down, or to score a touchdown. The QB also initiates and calls the plays. o Center - The offensive person who is in charge of “snapping” or “hiking” the football to the Quarterback. (“Hiking” means to hand the ball between the legs) o Receiver - The offensive person who runs a route down the field to catch a pass from the quarterback in order to gain yardage, a first down, or to score a touchdown • Rules o Interception - When the defensive player catches a pass intended for an offensive receiver o Sack - When the Quarterback has his flag pulled by the defense behind the line of scrimmage o Fumble - When the ball is dropped after being in possession o Line of Scrimmage - Each play starts on the line of scrimmage.
