In order for students to understand the fundamentals of chemistry, they must start small. What makes up an atom? Why is each element unique? What constitutes an isotope? How are ions formed? In this activity, 18 workstations are created, each containing various numbers of blue marbles (neutrons), black marbles (protons) and a number of electrons. At each station, students use their knowledge of the nucleus, along with the Periodic Table, to determine if the bag of marbles represents an element or ion. This simple and straightforward activity helps students understand the basics of a fundamental atomic concept, the nucleus and the particles that compose it. Includes student handouts, Teacher Notes and all necessary supplies.
Super Value Kit is complete for 15 student groups. All materials are reusable!

HS-PS1-1: Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
HS-PS1-2: Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-PS1-4: Develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy.
