So kids aren’t playing with rubber bands and string anymore?

True story: Recently I took a small group of students to visit a lab, and while breaking for lunch on some garden benches, they began climbing the trees nearby. They were getting a bit noisy when a lady walking by stopped and looked up into the branches. I thought I would get asked to get them to ‘behave’. But the lady smiled and said loudly to others passing by, “Look! look! children are playing on trees again!”

It took me a few seconds to figure out what she was really saying – that having seen so many kids today plugged into screens, it’s thrilling to see them having fun scampering up trees. (Side note: this was outside a Mars Space lab in Tempe, Arizona, and we were on a field trip to see a whole lot of technology!)

I keep this in mind when I introduce students to new technologies. Last week, I began a lesson on animation, and as subject matter, I returned to the ‘Rube Goldberg Machine.’ We don’t always need screens for this. (Unless we need to check out the many Rube Goldberg contests like this.). How could we turn students into makers, and innovators, problem-solvers and scientific thinkers?

A Rube Goldberg Machine (or ‘contraption‘) teaches us a lot about levers, gravity, kinetic energy, and chain reactions among other things – such as precision, iterative design, and learning from failure. All it takes is some lengths of wood, string, paper cups, shoe boxes, old clothes hangers, marbles and/or ping-pong balls, rubber bands and cardboard tubes.

I like to get them to ‘design’ their machine first, and see what they come up with – then set them on a building mission! We could use a drawing app, but paper and pencil work just fine!
