The first time we tried this challenge the kids were quite aghast at the lack of materials available! They have a small selection of items and they must build a car that rolls and travels forward- hopefully in a straight line.
The problems they encounter are met with a fabulous diligence because ultimately they want the cars to perform. The promise of races with other teams makes them work really hard!
We have built a good variety of cars in our class. The biggest problem we encounter with every car is that axle.
Designing the Car
Again, we have built a lot of little cars. Most of them are built of cardboard and the kids make a box. For this challenge one of the materials is a paper plate.
Yep, a paper plate.
Making wheels is another dilemma we run into whenever we make a car. I discovered a long time ago that making round objects and then cutting them out nicely is a challenge for kids!
Attaching the Balloons
Each group has several balloons and they must determine a way to attach them and still be able to blow them up. And, the balloon has to stay attached when it is released.
The group above tried a double set thinking this would make it go faster and farther! What do you think happened?
Every year I have groups that add their own flair to this challenge. This year was exceptional. Below you can see the Pizza Car, a cone-shaped car, the open taco car, and a couple of box-shaped cars.
Balloon Cars are a quick challenge with only a few materials and one that kids will love! Perfect for a lively Friday afternoon! You will have a BLAST!
