  1. Parachutes…. What a DRAG! Miss Laverty

  2. March 13th, 2012 Instructions • Hand out the work books • Grab today’s handout from the bin Today’s Plan • Drag Racers • Parts of a Parachute • Parachute Design Challenge • Forces of flight game (Simon says)

  3. Drag Racers • Materials: large garbage bags or table cloth, tape, stopwatch

  4. Drag Racers Procedure: • Tape 2 large garbage bags together to make a drag-chute • Measure a distance of about 20 – 30 meters for the “run way” • Have two people run with the drag-chute in between them • Try with the chute open and with it folded • Time each attempt

  5. Drag Racers • Which method took longer? • When it was open • Why? • When the chute was open it has more surface area so there is more air resistance (DRAG) • Real life examples: • Drag race chutes for cars and space ships

  6. Parts of the Parachute

  7. Parachute Challenge • Your challenge is to create a parachute with the materials provided that will drop as slow as possible • We will be testing out the parachutes tomorrow. • The person with the best (slowest) parachute will then get to attach an egg to their parachute as a final test. • You have the rest of today’s class to work on your parachute. Please use this time wisely.

  8. Parachute Challenge • Use your materials carefully as you ONLY get the amount listed below: • One sheet of plastic (half a garbage bag) • 2 meters of string • 10 pieces of tape

  9. Title Pages • Air is fluid and can be compressed • Air has mass and exerts pressure • Air is composed of different gases • Bernoulli’s principle • Lift must overcome gravity
