Our district has multiple fablabs in K-12 schools and has found that teaching through PBLs is a great way to incorporate lasers, 3D printers, CNC machines, etc. The students are solving authentic problems and can use the laser cutter (or any other maker tools) to make their prototypes. In fact, we rarely tell them exactly what machines they have to use. Instead, we allow them to dream up their prototypes and then coach them on what tools might best be used. Some multidisciplinary PBL projects that we have done recently include creating a Pinball machine (with the following content standards of calculating angles, measuring velocity, creating themes, etc), making lamps (circuitry & coding), and reimagining a piece of art (history, art). Here is a resource for our district's fablabs (
