How Solid is Your Tower?

First grade has been learning about properties of solids.  Some solids are flexible or rigid, smooth or rough, opaque or transparent, hard or soft. During this investigation, we were engineers!  As engineers, we needed to know the properties of the solids we were using to build a stable tower.

We measured how tall our tower was.

Sometimes the towers toppled over...so we tried a different way to use our materials to make a stronger tower!
