2nd grade has been exploring motion! They have built cardboard ramps to investigate how big and small wheels roll!
 |
| We made rollers that wobbled. |
 |
| Some rollers could go around the corner! |
 |
| Oh the combinations! |
Next we investigated how cups roll...did they roll like the wheel combinations?
One of the challenges was to "park the car". The cup rolls off the ramp and then parks underneath the ramp.
One of the hardest challenges is for the cup to fall of the ramp and land face down (upside down)!
 |
Another challenge is to work together and
have the cups roll straight. |
Once the cups could roll straight, we taped a penny in various places on the cups to see how the added weight changed the way it rolled!
