While it took some time to get the STEAM by Design students fully committed, we have lift off or rather marble off. My thanks to John Umekubo @jumekubo at St. Matthew’s Parish School for the inspiration with his marble run project http://www.creatorsstudio.org/special-projects/magnetic-marble-run-wall There have been many iterations by the students to get theirs working and as you can see many interpretations on designs. I gave the student the following information and directions. Your name must be on it, and these are the measurements you need. Marble, 18 mm, Magnet is 15mm x 3mm and Tinkercad hole measurement diagram.
I did not discuss mass, plane, or gravity. While I wanted them to prototype with cardboard, this aspect is a weak point with our students as most want to get it done like on a checklist. I will keep working on this aspect since we have no grades to motivate this type of hurried learning. Today the students were pretty excited to see how it could work and I have to say, it is pretty awesome. I love how students will play on it during the day.
