We've been continuing work on our recycled cars. 2nd graders began by using their journals to sketch ideas and then moved on to constructing the car body from cardboard and masking tape. Next step is assembling the wheel/axel components. I've had a group of faculty, staff, and parents diligently collecting plastic bottle caps for me. It turns out that these caps, with holes drilled into the center and connected with a skewer, make great wheels. We also discovered that if we put a thin straw over the skewer axel we get a nice smooth roll. 2nd graders are finishing up their construction and are adding some decorative touches. They are getting excited for a little friendly car racing.

We are continuing our linear motion study by designing and building cars from recycled materials. Our goals are greatest distance, rolling in in straight line, and speed. Finished cars will be tested in all of these categories. We've begun with sketching designs and considering size of shape. Their has been debate about balance, weight, and aerodynamics. We are excited to start building. Our first deep dive is into linear motion. There is no better tool to begin this exploration with than marble boards. We are doing the classic challenge of slowing the marble down and building an understanding of the forces that effect linear movement.
If you don't have marble boards in your space, they are the best tool. Check out the Tinkering Studio tutorials for building and using these educational workhorses. In second grade we've been making our maker-ed journals and starting our deep dive into motion. Second graders who finished up their journals got to work thinking about motion by playing with different toys and gathering verbs for how they move. Then we practiced drawing motions. This was a great way to get us thinking about the many ways something can move. ![]()
