After playing with FabLab and just a couple more small challenges, I felt the students were ready for a new and difficult challenge - and boy did they prove me right!
Challenge: Create a design for Mr. Schwengel's Swimming Pool that will surround his lovely home on three sides and have a combined volume of 275 cubic feet (we use inches on the design as this is a scale model). Since the pool surrounds my house this means the students must combine three shapes that total 275. Using FabLab is perfect because the students can "sink" the pool under the ground-level of the house. As you can see below, the students did a wonderful job.
