Poor.
Explain one way scientific knowledge can change over time.
New evidence, discoveries, or technology can lead to new understandings.
What is the set of steps scientists use to learn more about their specific discipline?
The scientific method.
What is a procedure?
A set of steps that scientists use to perform their experiments. It's like a recipe.
What makes a good scientific question? Give an example.
A good scientific question often includes what the manipulated variables and the responding variables are. Example...
What is the difference between reliability and validity?
Reliability is about getting similar results when an experiment is repeated.

True or False: Taste mapping is the correct idea that the human tongue has certain parts of the tongue that taste certain tastes such as sour, bitter, umami, sweet, and salty.
