Scientific Investigation
A prediction about the relationship between variables. Uses the if, then statement.
What is a hypothesis?
Energy that is stored. An object is not in motion.
What is potential energy?
The path of an electric current that does not allow the electricity to flow
the ways living things interact with other living things and nonliving things
