2 of 9

Questions to Consider

  • What will be our independent variable LEVELS?
  • How will we find the area? 400cm2
  • How many strings?
  • How will we drop the parachute?
  • What data will we collect?
  • How can we make our parachute the best?

** ALWAYS USE METRIC IN SCIENCE.** cm, m, km..

Materials List for Parachutes

**When you pick up your materials, get a plastic bag and label it with your names and hour. At the end of each hour tie it up, and place it in the _______ hour box. NO TAPE!! **CHOOSE 1 VARIBLE TO TEST (3 LEVELS)!!**

  • Our independent variable will be ...Materials, Shape, or String Length??

​

**PARACHUTES MUST BE EXACTLY

400cm2 **

Parachute Competition Rules

  • We will all walk over to the far side of the bridge with our best parachutes in hand.
  • Your group will go head-to-head with another group.
  • I will count to 3...parachutes are dropped on 3.
  • If a parachute goes into or near the street...I WILL GET IT!!
  • The winning team (parachute) will advance to the next round.
  • While other teams are dropping, you are watching and judging. NOT horsing around!!
  • The CHAMPIONSHIP round will be best of 3.
  • When we are finished, we will all return to the classroom, clean up parachutes, return army men to the bucket, and begin working on PRESENTATIONS.

GOOD LUCK!
