Chemistry (taught by Ms. Tonyan): In Chemistry class, we started a new project “Atomic structure.” Students have learned about the history of developments of atomic theory from 400 BC to the present day,  about philosophers and scientists who contributed to the theory, as well as about subatomic particles - protons, neutrons, and electrons - that form the atom. They continue learning about radioactivity, the types of radioactive decay - alpha, beta and gamma, and the changes in the composition of the nucleus. Using the method of modeling and simulation, students illustrate the structure of an atom of a specific element.
