Students will research how knowledge of the atom has changed over time, visually represent a historic atomic model and present that model to the class. Students can also explore the standard model of particle physics and discuss ways it could be depicted.

Students will learn how interactions among the protons and neutrons in the atomic nucleus affect the properties and stability of chemical elements, and how these properties could inform the creation of future elements.

This guide explores a variety of sugars and how they are modified in the body -- as well as how scientists follow those modifications.

These discussion prompts ask students about how isotopes can be used to label and track chemical molecules, and about sugars and the enzymes they interact with.

Students will simulate the exponential radioactive decay and half-life of carbon-14 with pennies and a food coloring/bleach chemical reaction.
