The first graders are now deep into our balls and ramps science unit.  Yesterday we explored the idea of force and tried to move a ping pong ball and a super ball with a straw.  We tried to see which ball was easier to move and we worked to see if we could blow hard enough to make either ball knock down a glue stick.

Every time we do a science exploration we spend some time writing about it!  Today we wrote about what we found yesterday in our science notebooks.  Here is one student’s writing about which ball was easier to move and which ball was harder to move.

“I think the ping pong ball is easier to move because it was small and it was a sphere.  I think the super ball was harder to move because it was 5 cubes [its weight!] and medium [its size].”
