The Great Weather Unit... Part 3

Today we made pinwheels... a fun little way to explore the wind and experiment with air pressure.  

It really is an art to figure out just the right balance of breath to make the paper spin around.

We used the pinwheel template from the free weather unit over at 123 Homeschool 4 Me. (Seriously this unit has printables for preschool to grade 4... Wonderful!)

After designing the pinwheel we attached them to pencil erasers with tacks.  (Which makes them not exactly 3 and under friendly)

The kiddos used a brief window of opportunity when it wasn't raining outside to run around and make their new toys spin in the breeze they created.
