A Pint-Sized Theory

Dr. Forrester introduces the concept of atomic theory, tracing its origins from Greek philosophers to John Dalton's contributions. The video explains that all matter is composed of atoms, discusses the periodic table, and describes how compounds and molecules form. It also covers chemical reactions, using a simple experiment with baking soda and vinegar to illustrate the rearrangement of atoms. The video concludes by highlighting the significance of Dalton's theory in modern chemistry and hints at future lessons on subatomic particles.
