  • Atoms, Model of the Atom, Atomic Theory | Middle School, High School

    Activity: Animation Activity: Building Blocks of Matter

    In this activity, students will view an animation that introduces them to the idea that everything is made of atoms, and that since atoms are so extremely small, even small objects contain vast numbers of atoms. They will see several examples to illustrate this point. Then they will be given a brief overview of the evolution of how people thought about atoms from the ancient Greeks through Dalton.

Students explore how a color wheel can provide a useful model for determining the colors of light an object may absorb or reflect. Finally, students will investigate the color yellow.
