For this investigation, 1st graders became engineers. The classes knew a lot about engineering and agreed that engineers build things. We also found out that engineers need to know about the properties of solids in order to choose the appropriate materials for each object being built.
The challenge...building a tower with our 7 solids (fabric, wire, tube, triangle, screw, wooden block and craft stick), foil, 2 cups, 2 cardboard squares, a straw and a rubber band. Oh, and no tape, scissors or glue!
 |
| A very stable tower! |
 |
| Measuring the tower just as it starts to fall! |
 |
| Trying to use all the solids for the tower. |
 |
| Working together. |
 |
| After building the tower, it's time to draw it. |
 |
| My tower won't fall over. |
 |
| It get's frustrating when your tower falls. |
 |
| How tall is my tower? |
 |
| Working together you get double the supplies! |
