Rubber Band Race Car
Learning how pull impacts push
The forces of push and pull
We experimented with 5cm of rubber and force and 10cm of rubber band force.
We tested our cars on carpet and tile and talked about how friction impacted our results.
Trials on Carpet
We launched our cars with a rubber band slingshot and measured how far they went with 5cm of force and 10cm of force.
Collaboration and Teamwork
Teamwork was very important to completing this activity correctly. We had to launch our cars, measure our results, record and analyze our data.
Trials on Tile
We had a lot more spinouts on tile, but if we got a good launch the cars went far. This was an awesome time to talk about friction and the positive and negative impacts it has in our world.
Balanced and Unbalanced forces
Spring Scales to Measure Force
We used spring scales to see what happened to our race cars when we pull them in opposite directions and the same direction with balanced and unbalanced force.
Protective Eyewear
We learned the importance of protective eyewear when working in the lab. We also learned how to care for and sanitize our eyewear.
