Structure of the Atom 3D Model

See inside an atom with this easy to make model.

• Five modeling sets and a teacher guide
• Easily assembled
• Use individually or in cooperative groups

Models are powerful tools for teaching science as they provide useful simplifications of structures and processes, helping to make the unseen seen and the complex simple. The nuclear model of the atom was developed after many years of theories and experiments. Atoms were found to have a very small nucleus, made of protons and neutrons, that is orbited at great distance by electrons. First, your students make their paper models of protons, neutrons, electrons, and electron shells. They then use their models to learn about the nuclear model of an atom.

The model covers the features of subatomic particles, electron energy levels, atomic number, mass number, ions, and isotopes. The model making kit includes enough materials for students to assemble up to 5 paper models, working cooperatively. The included comprehensive Teacher Resource Guide provides illustrated readings, activities, key vocabulary and an assessment, along with teaching opportunities for students to Engage, Explore, Explain, Extend, and Evaluate their understanding of the concepts presented.
