Tech Warriors lead the the younger Warriors at Arlington Elementary in an engineering challenge to create a container that can prevent an egg from cracking when dropped from a given height.

Divided into groups of 3 to 4, the Warriors were informed that, unlike their other STEM challenges, they would get to choose the materials they would use to build their egg carrier.  However, there was a twist: they would receive a limited amount of “money” to purchase their materials from the “store” — so they must agree in which ways to wisely spend their money in order to build the best carrier possible.  Each group received 1 twenty, 2 tens, and 5 ones for a grand total of 45 “dollars”.  The groups also each received 2 cups, a bag for holding their materials and money, and an egg for free.

The Warriors then had 15 minutes to design their carrier.  They had a sheet with the store’s price list and a space for drawing to brainstorming their ideas, and could not purchase materials until they came up with a good plan together, factoring in how much of each material they need and how much these materials would cost.

Finally, it was time to build.  The groups took turns visiting the store to purchase their materials and began their engineering challenge.  Over the course of several days, the students worked on their egg carriers.  On the final day, each group tested their egg carrier by dropping it from a given height onto the bare floor.  After the drop, the students took apart their carriers to see if their egg cracked or if they succeeded in the challenge of keeping their egg intact.

After the challenge was completed, the groups took turns discussing with the class why they decided to plan their egg carriers that way, what worked and what may not have worked so well, and what they would plan to do differently next time based on their results.
