Our science unit is called "Balance and Motion"!
We have been balancing objects by finding a good balance point. Then, we added counter weights, or extra weights to make the object more stable.
Here we are, balancing paper crayfish on our fingers.
(Good thing they weren't real!)
Balancing crayfish without counterweights is impossible! 
Let's try adding some counterweights!
Look at that! 
Counterweights placed on the bottom of the object helped it balance!
Way to go!
You did it!
Next, we balanced cardboard arches and triangles using what we already knew.
You did it!
You did it!
