Scaling down kit

This activity is designed to be accessible for all students. It’s a set of objects to helps students understand how small an atom is. Each step ‘zooms in’ 10 times from the one before. Some steps have three models, some have only two.

A variety of materials have been used for the initial steps in order to try and match the real objects. As the objects get smaller in their actual size, texture and colour start to lose their meaning, so after the blood cell, all objects have been 3D printed.

Many of the pieces are already designed models that have been collected in our Scaling Down Kit collection: https://www.thingiverse.com/svrc/collections/42748755/things

A document has been attached that explains the items at each stage of 'zoom', the scale the model needs to be printed at in order to be the right size for that Zoom level.
