Science SOL 3.2:  The student will investigate and understand simple machines and their uses. Key concepts include a) purpose and function of simple machines; b) types of simple machines; c) compound machines; and d) examples of simple and compound machines found in the school, home, and work environments.

I would have students make a 3D model of whatever simple machine they would like, and then have them explain the functions of what they made. This activity would include all 4 principles: creation, iteration, sharing, and autonomy.

Creation: We would explain what exactly simple machines are, and how one simple machine could come in many different forms. For example, a screw is a simple machine and it can come in the form of a nail OR a lid on a jar). This would let the students have many different options to choose from before they 3D print.

Iteration: I would have the students attempt to make simple machines on Tinkercad. They won’t know exactly what they are doing yet, but this would let me see their thinking process and see how they are transferring their thoughts onto the program.

Sharing: After all of their 3D objects are done, they are going to present their simple machines to the rest of the class. They will most likely see how much they have in common, while also learning things from other students who had a more detailed design.

Autonomy: The students will attempt to make a more specific simple machine and explain how they could use it in their day to day activity. For example, if they made a basic screw, they could then make a top that screws on to a jar and explain how they could put cookies in it and sit it on their kitchen counter.
