Glider Challenge











Challenge: To create a glider plane that stays in the air and glides for a long time.


Brainstorm solutions:


Brainstorm 1:


















Brainstorm 2:





















Criteria:


Constraints:
- Certain amount of blue paper
- Can't be too heavy




Test Phase




















From the test flight, I've learned that our plane nose dives too much. It doesn't have much hang time.

My goals for the glider
- Get it to hang in the air for 5 seconds or more
- Be able to soar longer without nosediving


Our glider didn't do so well. It nosedived as we predicted and it didn't have the best hang time. It was hard to change our glider since we already constructed it and took some of it apart.

I would change our design. I would add another set of wings and slant them upward instead of slanting them parallel. That way, there would be more of a change to hang in the air longer and soar.

"Egg Drop Challenge - Iteration #1"

Total # of achievements:




Achievements:


Brainstorm:






























Materials:


- Cardboard box

- Newspaper









Material size:


- My materials fit inside a cardboard box






Material weight:

- Weights more than 600 g






Drop Achievements:

I hit the bullseye









Egg Resiliance:

- My egg cracked but the yolk remained intact



- My egg cracked but was still together





Actual design:

































Since I didn't have enough time to brainstorm, I picked the easiest & most cheapest way. I got a box from home and lightly stuffed it with newspapers, making sure that each newspaper wasn't tightly crumpled. Unfortunately it didn't work.




The designs that were the best had mostly styrophone or popcorn and parachutes. If I could redo my design, I would put my egg wrapped in cotton balls in styrophone with a parachute on top.
