Pinwheel Experiment
Materials
needed:
Step
2: Fold it in half again, the opposite way.
Step
3: Cut along the folded lines, stopping halfway between the edge of the
paper and the centre.
Step
4: Fold one corner of each triangular section into the centre, taping it
down.
Step
5: This is what your pinwheel will look like when all four corners are
taped down.
Step
5: Place the straw on the back of the pinwheel and secure it with a straight
pin.
You
now have a working pinwheel. Enjoy! It works best by walking with it.
