MEETING MOLECULES

This kit is designed to help students differentiate between physical and chemical changes using extensive hands-on activities. Students model the states of matter: a solid, a liquid, and a gas; and the phase changes between them. They learn the difference between atoms and molecules. A great introduction to physical science and chemistry which bridges the use of common household ingredients and laboratory chemicals. Students investigate molecular motion in liquids, evidence of chemical change, and the effects of changing different variables within a chemical reaction. May be used as a stand-alone kit or as a companion kit to follow 1-132, Matter for Minors. Required, not included: hot plate, pot holders, glass beaker, various small containers, red and black construction paper, copy paper, citrus juices, milk, ice, matches, chemical splash goggles, and gloves. Designed for up to 30 students.
