Make a cool top in just about an hour with a few materials! They work great, are fun, and are a good engineering challenge for upper elementary students.
Materials
• 110 weight or heavier card stock
• Construction Paper
• Compass or circle template
• Glue
• 5” of 3/16” round dowel per student – only costs about 25 cents per 3 feet
• ¾” diameter wooden wheels with 3/16” holes (optional but with the optimal coolness)
