Students use LEGOs to identify various atoms, build different compounds, and count the number of atoms in chemical formulas. I use this with 6th and 7th grade students to give them visualization and something tactile to help with the abstract concept of atoms. It will also reinforce the function of protons, neutrons, and electrons in an atom. Included:- Learning Target and Success Criteria- Instructions on how to prepare the LEGO kits- Printable cutout cards to go in the LEGO kits- Procedure
