We spent a few weeks in January learning all about force and motion. We stood on chairs and watched the way things fall, we swung a pendulum from different heights and observed how that affected it's motion, and we rolled a ball from different heights to see if that changed how far the ball rolled.
Another of our experiments was to see if a ball rolled different distances on different surfaces. We set up our ramps and rolled a ball 3 times on the tile. We used Q-tips to measure the distance.
We recorded our results on our charts.
Then we tried it on the carpet.
And lastly, on some rubber cabinet liner.
We learned that the surface does affect how far the ball rolls! It rolled the farthest on tile, then carpet, and the shortest distance on the carpet liner.
Next, we experimented with wheels and rollers. We used pencils as rollers under our books and found out that they can make the book easier to slide.
Then we made our own wheels and axles. We rolled our wheels all over the room!
Before we took our test, we played a game to help us review. We played Jeopardy!
Team 2 was the winner!
