Kid-built in a few hours . . . this 7 inch tall basketball hoop can be assembled and re-assembled. We’re not going to toss a ball to make baskets with this project. Oh, no . . . we are making a little catapult to launch marshmallows at the hoop! Oh, yes! Sweet!
Use this building project as a challenging independent study for upper elementary, as a whole-class engineering project, or use it to make math and science applications like percentages, measurements and geometry, action/reaction, trajectory, etc.
I use the collapsible hoop and launcher for 3rd-5th grade GATE engineering groups. These groups are specific to gifted and talented students identified for nonverbal ability. Aside from my “regular” GATE pull-outs during the week which are cross-curricular, the nonverbal kids come back for an engineering session to end the week on Fridays. Here we measure, design, build, interpret blue prints, draft, and invent.
We try to keep the cost low. For this, you’ll spend a little on craft sticks (buy the big box, not the small packages) and some wooden wheels and dowels. I would estimate the cost to be about $1.00 per kid.
