Energy
What is potential energy?
The energy an object has because of its position; also the internal stored energy of an object.
What is a physical property?
a change that alters the form or appearance of a material but does not make it into another substance
What do plants need to perform photosynthesis?
sunlight, carbon dioxide, and water
What is a parasite?
on organism that lives off a host and harms it
What are the advantages of alternative energy sources like wind turbines?

Describe the elastic potential energy and kinetic energy of a rubber band.
It has the greatest elastic potential energy when it's stretched which converts to kinetic energy when it's released.
How does temperature affect density?
If the temperature decreases the density increases therefore in the temperature increases the density decreases
