Some of the exciting experiments inside:
Time: 30 minutes | Difficulty level: Easy
When the Eiffel Tower was built in the 1880s, it was the tallest human-made structure in the world. The design of the tower incorporated lots of triangles to help make it strong. In this challenge, you will learn how today’s engineers use geometry to design and build cell phone towers and tall buildings.
Pizza Box Solar Oven
Time: 20 minutes, plus cooking time | Difficulty level: Medium
The sun does more than just give us light. It is full of energy! Solar power is power that is generated from sunlight. It can be used for heat energy or changed into electric energy. In this challenge, you will use the sun’s power to cook food.
Cardboard Tube Suspension Bridge
Time: 45 minutes | Difficulty level: Challenging
Have you ever ridden in a car across a very long bridge? Most bridges that stretch a long distance are suspension bridges. In this engineering challenge, you will create your own bridge and learn how suspension bridges work.
