Making Molecular Models
In these creative hands-on activities, students construct several different molecular models that represent substances that play an essential role in our nutritional needs. Using gum drops and toothpicks, students design the models....
Curated OER
Structure of the Atom
Students observe 3 models that show Dalton, Thomson and Rutherford's theories of the structure of the atom. In this structure of the atom lesson plan, students observe each model and write a summary of each theory of the atom.
