1. PARACHUTE PROJECT BY: Jacob Rose

2. UNDERSTAND  First I looked at our specified rubric to understand what I was required to do.  Next, I looked at the given formula to predict the terminal velocity

3. EXPLORE  Then I explored different websites to understand more about parachutes.  I learned that the drag of the parachutes must slow the parachute down enough so that the terminal velocity is slow enough that the egg won’t break.

4. DEFINE  I used the equation, to calculate terminal velocity.  Our parachute had to be under 200 grams.  Finally, the parachute had to be packed into a compartment before deploying, which would allow it to deploy once a certain velocity had been reached.

5. Ideate - I used paper to make a funnel shaped container to hold the parachute - The funnel was then taped to the probe - The parachute was made out of pieces of wax paper taped together -Then I made a smaller parachute to help pull out the main parachute from the funnel - The smaller parachute was then tied to the larger one

8. Refine  The container was too small for the parachute, meaning it was packed too tightly to let air force the parachute out of the container.  So I added some space to allow more room for the parachute so it could get out easier.
