Descent of a Paper Helicopter

BACKGROUND: The scientific method involves the investigation of a question or problem by setting up an experiment to test n hypothesis. A hypothesis is a statement of what a student thinks will happen as a result of the experiment.

OBJECTIVE: Students will conduct an their own experiment to determine how their modifications affect the descent of a paper helicopter

MATERIALS:
* paper helicopter | * scissors| * stopwatch|
* 2 meter sticks| * chair| * calculator|

PROCEDURE:
2. Complete the problem, hypothesis, materials, and variables sections of the Lab Report. 3. Prepare the helicopter for flight. Cut on the solid lines. Fold on the dotted lines. 4. Stand on a chair to drop the helicopter from a height of 2 meters (you will have to measure this height first). When you drop the helicopter, start the stopwatch. Stop the stopwatch when the helicopter hits the ground. Record the number of seconds it takes for the helicopter to reach the floor in the data table (the time of descent). 5. Modify your helicopter. Repeat step 4 for the new helicopter. 6. Repeat steps 4 and 5 for wing lengths of 3, 2, and 1.

7. Calculate the average times of descent for each modification. 8. Complete the Observations section of the Lab Report.
10. Write a conclusion using complete sentences.
