This activity utilizes an online interactive simulation (PhET.colorado.edu) that allows students to explore and manipulate the subatomic particles that comprise the atom. Students also explore atomic mass, ions, nuclear symbols, and the periodic table. A link to the simulation and a downloadable file that includes a pre-lab, a student activity guide, and a post-lab assessment. The simulation also includes other inquiry opportunities and a game.

Chemistry: Atoms First is a peer-reviewed, openly licensed introductory textbook produced through a collaborative publishing partnership between OpenStax and the University of Connecticut and UConn Undergraduate Student Government Association.

This title is an adaptation of the OpenStax Chemistry text and covers scope and sequence requirements of the two-semester general chemistry course. Reordered to fit an atoms first approach, this title introduces atomic and molecular structure much earlier than the traditional approach, delaying the introduction of more abstract material so students have time to acclimate to the study of chemistry. Chemistry: Atoms First also provides a basis for understanding the application of quantitative principles to the chemistry that underlies the entire course.
