Day 3: Foam rockets

Day 3: We made foam rockets in class.
We used cylinders of foam for the main body of the rockets.
We used two triangles (which were originally one square) to make the fins.
The fins slotted together to make sturdy fins. 
We really enjoyed releasing the rockets outside.
These rockets work because when you pull back the elastic band, you store energy in the elastic band.
When you release the elastic band the force is enough to make the rocket fly.
Some of us are extremely good at launching our rockets!
