No telescope, eclipse glasses sold out, more visitors than expected? Here is a simple activity that works with common materials such as card board and household items.
Template spots and streaksExperiment with any perforated material you may find, in particular things with square and triangular holes.
Here is what we will be using at FHNW.
This activity has been inspired by Bob Miller’s Light Walk at the Exploratorium. The effect of the solar eclipse projected by the dozen will be amazing.
Have fun and take pictures!
