Gravitational Force

Today we learned about different forces.  We did an experiment to show how gravitational force works.

Joel: We learned how hard it was to hold a dictionary and then 4 atlases for 30 seconds

Diego: We learned about different types of friction.

Brooke: The 4 atlases was the hardest objects to hold for 30 seconds.

Amanda: The piece of paper was the easiest thing to hold. 

Chloie: We learned that we can use friction to keep our hands warm in the winter.
