We began by constructing tracks out of cardboard folded in half to make a v shape.  After seeing how difficult it was to make a corner turn we had the idea of making rolled paper pipes to let the marble roll through. Then we started thinking about height and began putting our pieces together using a chair as our base to gain height and also have a stable base to build on. We used the same paper piping as supports as well to hold up the ones the marble was going through. We also utilized the round cup form of the egg cartons to make corners and other interesting transitional pieces. Overall we had a really great time seeing what worked and what didn’t and coming up with different ideas. I think this was a great group project and we had an awesome time doing it and making our own marble run. I would love to try this out in my own classroom one day especially with high school students as I feel it could get really creative.
