Gravity - Helicopter experiment

Helicopter Experiment
Aim: To make a helicopter and look at the force of gravity.

Hypothesis: The size of the wings will effect the speed that the helicopter travels.

Equipment:

1. Stopwatch - use the Google stopwatch on your Chromebook
2. Helicopter template / paper
3. Paper clip

Method:

1. Make the helicopter by cutting out the template.
2. Drop the helicopter from a height. Use the same person.
3. Time each drop and record the time when it hits the floor.
4. Each time it is dropped you will make a change to its form.

• With a paperclip on the bottom.
• Use heavier material ( Cardboard)
• Cut the body in half to give it a short body.
• Cut the wings to give it short wings

1. Time each time you drop it.
2. Record the findings on a chart

Findings: What do the findings from your four flights say? Write about them.

Summary: What was the best result? ( The longest time will be the best. )
