“Hey grandpa,” Grandson said, “let’s play marble track.”
“Hey grandson,” engineer Grandpa said, “let’s be engineers today and invent our own marble track. We can learn about engineering, science, and kinetic energy.”
“Yes!” grandson responded.
So grandpa and grandson went to the hardware store and office supply and found parts for a custom marble track. They used 1/2 x 1/2 inch aluminum angle, adhesive-backed magnetic tape, plastic electrical flange (blue) cut into quarters and halfs, a modified funnel, and a metal backed dry-erase white board. They went home and cut the parts (safely), applied the magnetic tape to the parts, and created their own marble track. The configurations were endless. See the video here.
Science, Technology, Engineering, and Math (STEM) can be fun. Try this project and learn about kinetic energy and momentum.
