I have been fiddling around with paper switches and copper tape over the last few days and have come up with a load of new ideas. Paper switches open up a world of possibilities for students. They are simple to make and add a control or measurable element to any project that the students are working on.
I have recently written a project in Scratch that works out how far something has traveled in a period of time, the basic speed formula. As I wrote this, it occurred to me that this would be a great Makey Makey project for a standard science investigation, but instead of stop watches and inbuilt inaccuracies, paper switches and my Scratch code would give more accurate results.
I have now built this Scratch, Makey Makey and paper switch rig and tested it, it works really well, so armed with this, students can now accurately measure slope angle, slope length and even slope material variables and get fast accurate results.
Now that this has been completed, I am now thinking about how paper switches and Makey Makey or even Micro:bits could be used on projects such as marble runs. The more I investigate, the more ideas I get…
