1Start by building a cube by connecting the toothpicks to the gummy bears.
2Once your cube is made, test your structure by placing the book on top.
3If your cube is not successful, try building another shape, such as a pyramid.
4Build 3 pyramids out of the toothpicks and gummy bears.
5Try spreading them out and placing the book on top.
5Continue to adjust your structures as needed until they can support the book.
Warning:Be careful not to poke yourself with the toothpicks.
How It Works
Some shapes have more strength than others. Triangles give more support than squares when building structures. Triangles are used a lot in construction of things like bridges. An engineer can test many different solutions and each time they redesign it, the solution can get better.

In this lesson, we learn that:
Engineers use science and math to solve problems.
Engineers also build and test things.
Each time they re-design it, the solution can get better.
