Playing with Simple Machines
Have students consider a problem that could be solved by a simple or compound machine. Use Popplet to brainstorm ideas. Examples of problems are how to crack an egg, how to turn on a fan, or how to scratch your own back. Project a couple of Rube Goldberg cartoons for the class for inspiration.
2 Direct Instruction
Show Design Squad Nation’s "Chain Reaction Machine" video. Kids can get inspiration and procedural tips to help them get started building their own Rube Goldberg machines. In the video kids build simple machines, run into issues, iterate, and create a successful Rube Goldberg machine.
3 Guided Practice
In a collaborative group, have students apply basic physics principles to create a Rube Goldberg machine that performs a task. Some example tasks might include crack an egg, turn on a fan, dispense a treat, or turn off the light.
4 Independent Practice
Students will use Educreations to create a tutorial about how and why the group’s machine worked. They can annotate photos of their machine with narration or text.
Students extend the learning at home by solving contraption-building puzzles with the Rube Works app.
