Protons and neutrons and electrons, oh my! Physical science scholars get hands-on with interactive atomic modeling. Starting with a simple helium atom, participants create and name ions, then build isotopes. Questions throughout the interactive test their skills and provide feedback along the way.

Instructional Ideas

• Use the interactive to launch an atom model building project or lab
• Have students record their answers to questions throughout the resource for an easy-to-grade class assignment

Classroom Considerations

• Access the interactive by signing up for a free CK-12 account
• Learners with little knowledge of the atom can use the resource

Pros

• Constructing the atom model helps pupils solidify the location of subatomic particles, their functions, and how isotopes form for different elements
• The interactive model functions smoothly and can be reset to start the process over

Cons

• None
