100
Before a scientist does any experimentation, they must first make one of these; happens even before a hypothesis.
What is an observation?
100
These particles have a negative charge.
What are electrons?
100
These are made up of C, H, and O and have a ratio of 1: 2: 1. Main source of energy for living things.
What are carbohydrates?
100
All organisms require this, so they must eat food.
What is energy?
100
In a solution, this is added and dissolved into another substance.
What is a solute?
200
This is the variable that scientist measure and record to look for changes throughout their experiment.
What is a dependent variable?
200
These are found within the nucleus of an atom.
What are protons and neutrons?
200
These are made of C, H, and O. Can be saturated or unsaturated. Used for energy storage.
What are lipids.
200
An organism maintains a specific set of conditions, such as pH, temperature, etc.
What is homeostasis?
200
This property of water allows cohesion and adhesion to take place.
What is H bonding?
300
This is the variable that scientists manipulate and change in an experiment.
What is an independent variable?
300
This type of reaction releases energy.
What is exothermic?
300
Enzymes are made up of this type of molecule. Contain C, H, O, N and sometimes S. Monomer is an amino acid.
What are proteins?
300
These are beneficial traits that are passed down to offspring.
What are adaptations?
300
In a solution, this is what does the dissolving.
What is a solvent?
400
Information gathered and used for analysis during an investigation.
What is data?
400
In a chemical equation, these react with each other to form a product.
What are reactants?
400
DNA and RNA. Monomer is a nucleotide. Made up of C, H, O, N, and P.
What are nucleic acids?
400
An example of this characteristic is a rabbit running away from a predator.
What is responds to stimuli?
400
This measures the acidity or basicity of a solution.
What is pH?
500
This is an explanation of a phenomenon that can be made once several experiments have supported it.
What is a theory?
500
This is a substance that lowers the activation energy of a reaction to speed it up; Enzymes are an example.
What is a catalyst?
500
Monomer of a carbohydrate.
What is a monosaccharide?
500
This is why a population is able to grow in numbers.
What is reproduce to make offspring?
500
This is a phrase used to describe water because it can dissolve many different substances.
What is universal solvent?
