3rd class recycled rolercoaster

Made using only recycled materials. This rollercoaster has been a working progress over the past month.

The children faced many challenges in this construction.  Measuring lengths and widths of tracks and also experimenting with different heights to ensure the ball would have enough momentum to make its way down to the bottom.

We found that using skewers for support was important.  We also had lots of problem solving in areas where the ball was stopping or falling off the track.
