Physics: Triangle Appreciation Day

Last week we carried out a few experiments demonstrating the power of the triangle. The kids built squares and triangles out of straws and tested them to see which shape is more stable. Triangles won, and they used this fact to strengthen a 3-D cube made out of modeling clay and toothpicks and then cubes made out of straws and paperclips.

Check out how strong this cube is – that's some seriously HEAVY material!
