Forces and Design: Egg Drop Challenge
P3.2 Net Forces
Forces have magnitude and direction.The net force on an object is the sum of all the forces acting on the object. Objects change their speed and/or direction only when a net force is applied. If the net force on an object is zero, there is no change in motion (Newton’s First Law). 
P2.1A Calculate the average speed of an object using the change of position and elapsed time.
P2.2B Use the change of speed and elapsed time to calculate the average acceleration for linear motion. P3.4C Solve problems involving force, mass, and acceleration in linear motion (Newton’s second law). P3.4f Calculate the changes in velocity of a thrown or hit object during and after the time it is acted on by the force. P3.5a Apply conservation of momentum to solve simple collision problems.

PracticeYour mission is to safely return an egg to Earth after being dropped out our window (6m) using only the limited resources below. The rules for this assignment are as follows:
Materials
Day 1
Think about your materials and how your are going to use them. While doing this, make a Version #1 blueprint of the design your team is going to use using the picture as an example. Day 23 Construct your egg drop apparatus Version #1. Day 4 Conduct the actual egg drops and analyze the results. Complete the analysis worksheet in addition to the analysis discussion that we have after each participant completes their egg drops. Day 45 Revise design and create a Version #2 blueprint (use the picture as an example) and build. Day 67 Conduct the actual egg drops and analyze the results. Compare your results from Version #1 with Version #2 in an student created analysis that includes media.
