A very kind and resourceful mom is sharing an incredible idea she had for letting the kids understand the enormity of the geological time periods on Earth. The trick? Ingenious in its simplicity: using a very long multicolored ribbon. Different geological periods are indicated by different colors, their length – by ribbon length!

On top of the ribbon the kids were putting toy-dinosaurs, toy-mammoths, toy-humans and home made fossils to make the results both visual and tactile. I loved this idea so much, that I am definitely doing one of those for our own Geology units!
