One of our wonderings this year has been the strength of
different materials and how things move.
Is it the wind? Or our blowers? A fan? The pendulum?
After constructing buildings a few week ago, we began to test
those forces of motion to see what is the strongest.

Some of our observations and predictions are listed below:
Since Claire's is made out of blocks, it won't fall.
The pendulum is hard so it will knock down.
When blocks get too high, they knock down.
Some of it will stay up.
It's wiggling.
I made it shake.
We will test the pendulum on Monday! Stay tuned!
