Brief Description

Students will select one type of paper for their parachute (i.e. tissue paper, napkin, paper towel, etc.) based on what they think will work best. The students will make a parachute with the paper and string and attach a weight. The students will then test their parachute.

Lesson Objectives:

To learn about air flow and materials.

Materials Needed:

Tissue paper

Napkins

Construction paper

Newspaper

Paper towels

String

Tape

1/4 lb Weights (a few batteries tied together would also work)

Preparation and Set Up:

– Arrange students into groups.

– Distribute materials.

Necessary Background

Vocabulary:

Air resistance

Procedure

1. Explain the concept of air resistance to the class.
1. Air resistance is the force that acts on anything moving through the air. It is not very heavy so humans don’t notice it much. Without air resistance things would fall faster than they do. The more surface area an object has the more air resistance affects it. This is why parachuters use wide light materials to slow them down as they fall.

• Have students cut a circle with a 6 inch radius of a paper of their choice.
• Have students cut 8 12 inch pieces of string and tape them at equal distances around the edge of the canopy.
• Tape the other end of the string to the weight.
• Drop the parachutes from a decided height and see if it works.
• Repeat steps 2 – 5 with all the different papers.
• Discuss the activity as a class. Ask the students:
1. What material worked best for the parachutes? Why?
2. What didn’t work as well? why?
3. What changes would improve your design?
4. What about a larger or smaller canopy?
5. What would happen if you added more weight?

Extensions:

Take the paper material that worked best and test different sized parachutes.

Make parachutes out of different materials.

Have a competition to see what parachute can land most gently.
