Helicopter examples

The helicopter should be folded and look like this:

However, the Scouts can experiment with their helicopter by adding weight (paperclips) or even making changes to the blades (cutting to make more blades, folding blades at an angle to look at difference of surface area).



This is a great way for Scouts to explore and learn as they go, so it's important to not give them the answers directly.
