The subatomic particle that carries a positive charge.

What is the proton?

100

The first step in any scientific experiment.

What is observation?

100

This refers to the type of reproduction in which two organisms contribute genetic information to create a new individual.

What is sexual reproduction?

100

This is the variable the experimenter changes so he can observe what happens to the other variable.

What is the independent variable?

100

This type of molecule has an uneven charge throughout the molecule.  In other words, parts of the molecule are more positively charged and different parts are more negatively charged.

What is polar?

100

These are the four types of macromolecules.

What are proteins, carbohydrates, lipids, and nucleic acids?

200

The subatomic particle that carries no charge.

What is a neutron?

200

This refers to the information gathered during an experiment.  It is usually recorded in a table format.

What is data?

200

Something that causes an organism or conditions to change. In other words, it causes a response.

What is stimulus?

200

This type of data is recorded with exact numbers as opposed to the type of data that is more of an observation.

What is quantitative data?

200

When you dissolve water in sugar, the water is the __________.

What is solvent?

200

These are the small building blocks that make up polymers, or macromolecules.

What are monomers?

300

The subatomic particle that is negatively charged.

What is the electron?

300

After you have made an observation, asked a question and done some research, you do this.

What is form a hypothesis?

300

The type of reproduction that only involves one organism.  The offspring is identical to its parent.

What is asexual reproduction?

300

The variable that changes as a result of changes in the independent variable.

What is dependent variable?

300

When something is completely dissolved in water it is said to be in __________.

What is solution?

300

The new substance that is produced in a chemical reaction is called the _________.

What is product?

400

The location in the atom where the protons and neutrons reside.

What is the nucleus?

400
A good experiment avoids the influence of this on its findings.

What is bias?

400

This is the genetic material that is found in the nucleus of cells.

What is DNA?

400

This group is exposed to the same conditions as the experimental groups in the experiment but doesn't undergo the changes in the independent variable.

What is control group?

400

The attraction of water molecules to other water molecules is known as _________.

What is cohesion?

400

This speeds up the rate of a reaction.  Enzymes are a chemical version of these.

What are catalysts?

500

A version of the atom in which there is a different number of neutrons compared to protons and electrons.

What is an isotope?

500

This step comes before your conclusion.  It is where you look at your data and describe what it's telling you.

What is analysis?

500

This refers to the ability of an organism to maintain constant internal conditions.

What is homeostasis?

500

This is something that is supported by many observations and scientific experiments over the years.

What is a theory?

500

Something that has a pH of 3 is said to be _______.

What is acidic?

500

The energy needed for a reaction to take place is known as the ___________ _______.
