A molecule is made up of atoms. We know how atoms look from pictures. Today we will use colored beads and sticks to make an atom. The beads will be the molecules and the sticks will be the bonds. Atoms join to form small particles of matter like bricks make up buildings and rocks make up a stone wall.
Atoms join to form small particles of matter.
Salt is made of two different atoms. You will need to join several colored beads together to form different models. Then, look at the models that have been created. Students will then match their models with the actual item. Today, we have defined an atom and a molecule.
