1. Rotocopter Lab
~I can calculate speed.

2. Question
What is the effect of wing size on the falling speed of a rotocopter?

3. Hypothesis
~If, then because statement.

4. Experiment
Make the rotocopter following the direction at your table.

5. Data Wing Size and Speed Height (cm) Time (s) Average of Time
Speed (cm/s)
Distance ÷ Time
Trial 1
Trial 2
Trial 3
Regular Wings
200 cm
Medium Wings
Shorter Wings

6. Directions
Stand on the table and measure the distance you are dropping the rotocopter to the floor.
Drop the rotocopter from that distance and record the time it takes to hit the ground.
Record the data.
Fold the arms to make it shorter. Then drop from the same distance and record the time it takes to hit the ground.
Fold the arms to make it the shortest.Then drop from the same distance and record the time it takes to hit the ground.

7. Complete the data
Calculate the speed of each rotocopter. Show ALL your work, units, and formulas!!!

8. Finished??
Write your conclusion!!
