March STEM Challenge 2017

bunnypeeps

What says spring better than those colorful, marshmallows you see in every grocery store?  I’m talking about Peeps, of course!  And this month, our students are going to give them some air by creating Peep Launchers.

This idea comes from a packet of wonderful ideas that you see here.  Our building completed the Peep Puff Mobile last year.  So fun!

Each pair of students will need 2 toilet-paper tubes (or 1 paper-towel tube, cut in half), tape, a single-hole punch,  a pencil, a pen or marker, 2 thin rubber bands, scissors, and a marshmallow Peep (bunnies work best).

For this challenge, I wanted the students to focus on perfecting their design to achieve the highest average distance in three trials.

I gave them this link with directions on how to assemble their slingshots.  Have your students watch the fun little video (2:12).  It explains how the slingshot stores potential energy when the plunger is drawn back and releases kinetic energy when you let go!

You can download and print the instructions OR you could simply put them on this site and let them follow the directions.  The reading teacher in me selected the latter and had great results with fifth grade.

Design Squad Slingshot

The students and I set up ten feet of measurement tape in the middle of our Makerspace for our trials.  Each pair came to the center, and gave it their best shot(s).  We rounded each to the nearest foot.

In this challenge, everyone wins – a Peep to taste, that is!
