Acid and Base Tokens

thingiverse

I created several quick designs for our acid/base activity, primarily as a reward for my students if they were paying attention in class. The circle sizes are accurately proportioned to each respective atom's covalent radius. Although these compounds are ionic in nature, I thought using this metric would be an effective way to visually demonstrate their rough appearance in an engaging and aesthetic manner that would excite the kids and make them eager to receive it as a reward.
