Scientists use different types of tools to investigate how and why things happen. Here are some examples of these tools: a diagram of a food chain in the Everglades, a plastic replica of the human digestive system, a mathematical equation for finding the speed of an object. What word describes all of these examples?
Model
300
The testable variable. The factor that is manipulated/changed by the experimenter.
What is the independent (testable) variable?
400
What are two ways scientists show creativity?
In designing experiments and coming up with explanations.

What might cause a scientific theory to change?
New evidence.

Used to show how each group of data relates to all of the data.
What is circle graph/pie chart?

Lee wants to make sure she understands the components of a good scientific investigation. She knows that it should be controlled and have a large sample size. Also, she thinks that the results should be communicated to other scientists. Which is another component that is necessary for a good investigation?
It must be carefully planned and able to be replicated by other scientists.

Physical model.
500
Something that doesn't change in an experiment. It stays the same.
