7. Observation Finding out about something using your five senses: seeing, hearing, touching, smelling and tasting. You can observe color, temperature, weight, sweetness, volume, mass, etc. Good scientists use all their senses during experiments to gather as much information as possible.

8. Prediction State the result we think will happen. Relates to our hypothesis.

9. Scientific Method A set of steps used to find answers to questions. Steps of the scientific method: Ask a question--> gather information --> form a hypothesis --> test your hypothesis--> draw conclusions --> Repeat the process if necessary.

10. Theory An idea that explains something based on repeated scientific observations and experiments. A theory is an idea or principle that has been tested by many scientists over a period of time. It is on it's way to becoming a fact if it is not disproven. Example: Theory of evolution

11. Variable any part or factor that can change the outcome of an experiment. Any part of an experiment that you change or is changed during the experiment. Variable means "change"
