Teaching ScienceIdeas and help for trainee Science teachers

Here are two great links to demonstrate the relative size of objects, from an atom up to the universe!

Scale of the Universe lets you scroll from the entire universe, down to the Solar System, a human, and then even smaller, down to sub atomic particles. It’s a great way to visualise aspects of scale. You can see it here.

Similarly the Cell Size and Scale interactive from the Genetic Science Learning Centre, University of Utah, takes you from a coffee bean down to a carbon atom.
