Egg Drop Challenge - Iteration #1

This is what our egg drop design was based on, the mars lander crash bags. (We don't have a picture of our actual final design)

next year's Egg Drop Challenge.
-Suggest a redesign to the activity that Mr
Olson confirms he will use for next year's Egg Drop Challenge.

Designs such as that of Joe and Josh (pictured below) were successful because they took into account the actual criteria, instead of making a design and then cutting corners to try to make it fit into the criteria.


Things it did right:

• Extremely light: it received all of the weight achievements.
• Safe: the egg looks and is very unlikely to break, giving you many more achievements

Things that could have been improved upon:

• Size: the solution didn't receive many of the size achievements, but made up for it with its excellence in other areas
• Accuracy: as with our original design, they chose to use a parachute. However, we found that the parachute caught the wind and made it less accurate. This design would have probably done better without the parachute.

Personal redesign ideas:

• Guiding weight: if our own design had had more weight, it would have dropped more accurately. The wind was too strong for our design and blew it off course.
• Less cotton balls: the cotton balls on the top would be unnecessary with a weight, since then you wouldn't have to worry about it dropping upside down and making the egg break. This would have allowed us to get some more size achievements.
