Science: Eggshell experiments!
We balanced a book or whiteboard on egg shells.
Next, we carefully added weights.
We had to make sure the weights were balanced.
Each weight was recorded on a whiteboard.
Some weights were metric units
Other weights were imperial.
We kept adding weights until...
The egg shells cracked and
That final task was to total the weights
Any imperial weights were converted to metric
We recorded the maximum weight held.
