What is a independent variables?
A independent variable is variables that are manipulated or even changed by the researcher during an experiment. They do not get effected during the experiment, meaning that it'll not be changed when the experiment occurs.
Independent variables are factors that are manipulated or controlled in an experiment.
They are the variables that are changed intentionally by the researcher.
Independent variables are used to test their effects on the dependent variable.
There is one independent variable throughout the experiment.
What is a dependent variables?
The dependent variable are the main focus of the experiment, where the scientist will focus their observations on to see if change occurs.
Only one dependent variable.
The main focus of the thing your measuring.
What is a controlled variable?
The control variables are variables that isn't changed by the scientist at all during the experiment. They are kept constant so that only one variable effecting the experiment.
There are many controlled variables during the experiment.
Stays the same though out the experiment.
What is mitosis?
Two daughter cells from the parent cell which are both identical to the mother (nuclei). Only two daughter cells get produced.
What is meiosis?
Results in half of the DNA required, which means that they aren't identical to the mother. Only four daughter cells get produced.
What is asexual reproduction?
Asexual reproduction is the act of one individual required to reproduce, this means the animal can have children on its own as it already houses the required systems.
One parent required.
DNA is identical to parent.
What is sexual reproduction?
A sexual reproduction is the act of requiring a male and female individuals to reproduce and produce children.
Two parents.
Different to Parents.
What is reproduction as a whole?
Reproduction is the biological process of which organisms create offspring or have individual of the same species.
What is the unit measurement of energy?
The unit measuring the measurement of energy is Joules (J).
What is the law of conservation of energy?
The law of conservation of energy states that the amount of energy cannot be created nor destroyed, but rather transferred into a different type of energy.
What is energy?
Energy is the capacity to do work or cause a change in the systems. It can come in various forms and types that are unique to their own ways. One of the many types of energy is.
What are the types of potential energy?
Heat energy.
Electrical energy.
Chemical Energy.
Kinetic Energy
Light energy.
Elastic potential energy.
Sound energy.
Explain the types of energy?
Heat energy
The energy involved with the heat of the object, it flows from the hot objects to cold objects. This can be seen in cooking.
Electrical energy
This energy is carried by the electrical charge, this is often used to power objects such as light bulbs and even laptops.
Chemical Energy
The energy stored in chemical bonds, this is where if a chemical reaction occur they usually release or absorb energy during the reaction. Examples can range from a human chewing food, where the food has chemical energy to fuel up the human.
Kinetic Energy
Kinetic Energy is the energy of motion, everything can have with various levels. If a ball gets kicked the kinetic energy would transfer to it.
Light energy
Light energy usually comes from the Sun or even light bulbs, they are the type of energy that is in the air vibrating.
Sound Energy
Sound energy is the vibrations in the object which as a result produces sound.
What are the types of potential energy?
Elastic potential energy
Gravitational Potential Energy
Chemicals Potential Energy
Explain the types of potential energy.
Elastic potential energy
Elastic potential energy is energy stored in a stretched or squashed spring. Elastic energy occurs when objects are impermanently compressed, stretched, or deformed by an action.
Gravitational Potential Energy
Gravitational Potential Energy is the energy stored in an object when it is above ground.
Chemical Potential Energy
Chemical Potential Energy is the energy stored in substances.
What are the three forms of heat transfer?
Conduction
Convection
Radiation
Explain Conduction.
Conduction is a solid-to-solid heat transfer, where it requires touch to transfer heat to another objects. This is done by the warmer object first transferring to the cooler object.
Explain Convection.
Convection is the process of liquid and gas (not solids), where the heat rises to the top while the cold sinks down to the bottom in a cycle.
Explain Radiation.
Radiation travels using the electromagnetic waves through space, and can travel through a vacuum; in this case it would be no air, nothing, empty space.
What are Protons?
Protons are tiny particles with a positive charge, found in the center of an atom (the nucleus).
What are Neutrons?
Neutrons are tiny particles with no charge (neutral), also in the atom's nucleus. Neutrons help stabilize the nucleus and contribute to the atoms mass.
What is Electrons?
Electrons are very small particles with a negative charge, that orbit the nucleus of an atom. Elections are responsible for chemical bonding and electric transfer.
What are the steps of the scientific report sequence?
The steps for the scientific report sequence are;
Title
Aim
Hypothesis
Materials/ Equipment.
Method
Results
Discussion
Conclusion
Bibliography
Explain the scientific report sequence.
Title: A statement or question which describes the experiment.
Aim: What you are attempting to find out, it starts with "To" followed by a verb.
Hypothesis: A educated guess using your current knowledge, as well as a "If, then" statement.
Materials/Equipment: What materials used during the experiment.
Method: A numbered step by step procedure of what you did in your experiment.
Results: What was found, these results can be put into a graph or even a table if possible.
Record of observations and measurements that you made.
A graph must be included in your results (line/column graph)
Discussion: Discuss the results found, and answer your hypothesis.
What do the results show?
How can the results be explained?
Conclusion: 2-3 sentences linking it to the aim, and it must be past tense.
A statement that describes the effect of the independent variable on the dependent variable (answers your name).
Bibliography: A bibliography is an alphabetical list of all sources you've used to complete and research your experiment.
