Elementary school students learned about physics and architecture through building towers from various materials. Older students were challenged to build the tallest tower they could, using ONLY newspaper and tape! The kids were successful in building a tower that was taller than they were. They learned that pleating or rolling paper can help to increase its stiffness and sturdiness. (http://www.pbs.org/wgbh/buildingbig/educator/act_tower_ei.html)
Younger students explored the laws of physics on a smaller scale – they built structures using only gumdrops and toothpicks. Some tried to build the tallest tower, but others just built a sturdy house! These students learned about shapes that would make their structures strong – for example, triangular walls held up much better than square ones did.
