Experiment:
Make one change to your helicopter. Some suggestions are:
Fold the bottom up one more fold, or
Make the wings shorter, or
Make the wings a different shape

**You may want to make another helicopter, making a change, so you can compare them**
Ask:
Does it fly differently? How is it different?
Would a different change have the same result or a different one?

Choose a way you'd like to improve your helicopter. Such as:
Making the wings spin faster.
Making the wings spin slower.
Make the helicopter rotate (spin) more times during flight.
Have a longer flight (more time before hitting the ground).
Make it spin in the opposite direction.
Make a change to your helicopter design that you think will make the improvement
you chose.
Test your new design.
Redesign
Make changes and test until you have your best paper Mars Helicopter design.

Want to Keep Experimenting?
Tape a long strip of a light material to the bottom of your helicopter. (Ribbon, streamer,
other light and long material)
Hold the helicopter up with the material hanging straight (untwisted) below.
Step on the loose end of the material, or place a weight on it.
Drop the helicopter.
Pick up the helicopter without turning it and count the twists in the material.
Counting the number of times your helicopter rotates (spins) while it's flying, can be difficult.
One way to do it is to count after.
