The 3d Printed Spring Scale can be used in place of regular education spring scales. The learner can engage in Force, Torque and Weight measures. The Spring Scale can be introduced to existing Science and STEM curriculum. Giving the student the option to print, assemble and use their own tool to enhance the experience. At the end of the lab the Student can take the 3d Printed item outside the classroom for additional measurements.

The time tested project of many High School and College Physics curriculum, this 3d printed version brings this classic into the modern age. Even lighter than Balsa wood and infinitely more modular, the 3d Printed Mousetrap allows the student to engage in 3d Design and Manufacture with their project.

Potential and Kinetic Energy
This concept design for potential and kinetic energy was a first take at a larger scale participatory lesson. The students strapped a Android based phone to a skate wheel car and took measurements as the car oscillated up a down each side.
The first attempt at this ramp was not terribly successful. I will need to add rails on the side to keep cars from veering off the ramp. Also, the ramp was not quite sturdy enough for a Skateboard.
The humble pegboard can be used in a variety of ways. An all pegboard Rube Goldberg. Demonstrating the Cartesian graphing system. The limit to the usefulness of this board of holes is hard to measure.
Pegboard Rube Goldberg
Simple construction with 2×4’s and 4 2’x4′ Pieces of pegboard.
The lesson can be as simple as dominoes on inclined planes.
Watch this for an animation of virtual dominoes
Or use whatever you can find around the garage.
Teaching Thermal Properties using the “Design a Thermos” style lesson. It is a tried and true approach. This Lesson Plan Adjunct attempts to add elements of coding and design into the mix.
