Investigating Force with Spinners

What force is creating the spinner to spin fast or slow?

How can we construct a spinner that will spin 

slowly to the ground?

What parts of the spinner are important elements to consider when making a change?

The children constructed a paper spinner from a simple model. We experimented how quickly or slowly they fell to the ground.

Next we innovated on the original design by changing one or two elements. for example: a longer blade or shorter handle. The children were required to record their predictions and experiments as part of their learning.
