We investigated ramps in the classroom last week. We discovered we needed more room to allow the balls to roll. We compared how far different balls went in the hallway. The children discovered that smooth balls roll farther on smooth surfaces. Then we tested if taller ramps made balls roll farther, and they did. We even made a graph of our results.
 |
| We moved our lesson to the hallway so that the balls could travel farther. |
 |
| We made ramps using blocks and boards. |
 |
| The beach ball went a shorter distance than the utility ball. |
 |
| The children watched and were excited to see if their predictions were right. |
 |
| We conducted a survey to see which ball the children thought would go the longest distance. |
 |
| Our second investigation was to see which ball would go the longest distance. We discovered that the the rubber ball and the plastic ball went about the same distance when the ramp was one block high. However, when the ramp was two blocks high, the rubber ball went much farther. We counted the bricks on the wall to see which went the the farthest. |
