Covers all bases
This sci-object is great. It provides many "CFU"s, ways that students bring in misconceptions, a variety of activities (simulations, hands-on activities, etc), and brings in the history of how the structure of the atom was discovered. Provides a lot of inspiration for developing lessons and helps to brush up on the concepts around atomic structure. I also really appreciated the beginning, where charges were explained before going into the specific atomic particles.
