This is the first part in a 3-part lesson on Molecular Interactions. This part introduces 6th-grade students to the fundamental structure of an atom, the basic building block of all matter. Using the work of chemist Mario Molina as an engaging real-world example, the lesson teaches the key distinctions between the three main subatomic particles: Protons: Positively charged particles located in the atom's center, or nucleus. They act as an "ID card" that determines what element the atom is. Neutrons: Neutral particles with no charge, also located in the nucleus and keep the protons from shooting away from each other. Electrons: Negatively charged particles that zip around the nucleus. Because they are on the outermost part of the atom, they are responsible for all chemical interactions and reactions.
