Over the last five weeks, my class conducted several experiments** with household cardboard tubes, marbles of various masses, and wooden blocks, to see what might produce the desired effects in their culminating project, the "Mega Marble Roll." Today they put their ideas to the test. Each team selected a problem, then designed and built a marble roll to solve it. They would like to share what they learned with you. (And would love it if you would leave them an encouraging comment or two! YOU are their audience!)
**Lessons are taken from "Measurement with Marbles" by the Math Learning Center.
Group #1 Problem: include two uphill and two downhill ramps
Group #2 Problem: include two jumps in your marble course
Groups pose with their finished products:
And a quick
demonstration on averaging for the families...
Thank you for visiting our class. Please come again soon! (And the class thanks you for your comments!)
