Is a melted popsicle an example of a physical change?
What is YES? You can melt and refreeze a popsicle and it will still be a popsicle.
Is rust an example of a chemical change?
What is YES? You cannot change rust back into the metal is was before; therefore, it is a chemical change.

What is freezing and melting water to and from ice is an example of a physical change?
True or False. Turning peanuts to peanut butter is an chemical change.
What is FALSE? To make peanut butter, you grind up roasted peanuts, so nothing new is being created.

CHALLENGE: Explain how the water cycle an example of a physical change.
What is YES, it is a physical change, because water changes from a liquid/solid when it precipitates, to a gas when it evaporates, then forms back into a liquid when it condensates. Then the process repeats again with the same substance, WATER!
