Current slide {CURRENT_SLIDE} of {TOTAL_SLIDES}- Best Selling in Chemistry
This kit has enough model atoms to construct organic & inorganic chemicals up to benzene rings and sugars, which takes it through high-school chemistry. I also found it good to play with my granddaughters (aged 3 & 5) who enjoyed joining all the atoms together into shapes, just like playing with "Lego". They don't yet understand how we breathe in Oxygen and breathe out Carbon Dioxide, but I think they are coming to understand that the world is made up of tiny molecules that are too small to see.
