Physical Science

  • SCUBA Diving and Gas Laws Students are often fascinated by extreme sports such as SCUBA diving. This interest can be harnessed to teach an exciting lesson on gas laws. Five gas laws are discussed, and each discussion is centered on the law’s compelling, real-world connection to SCUBA diving. View »
  • Water: A Liquid That Can Take the Heat Water has the ability to absorb a lot of heat and release it slowly over time. This helps moderate coastal climates, and makes for some attention-getting demos. View »
  • Imploding Soda Cans: An Inquiry Approach Your students have probably seen someone crush an empty beverage can with their bare hands, or have even crushed one themselves. But have they ever seen an open can seemingly crush itself, like magic, without the presence of a visible, physical force? View »
  • If Life Hands You Lemons Make a Battery Demonstrate how batteries work with a fresh approach: use lemons for the liquid electrolyte that completes an electric circuit. View »
  • Crystal Growing Lab Introduce your students to crystal growing with this engaging activity. View »
  • Rock Candy: An Edible Study of Crystallization Making rock candy is a safe way to introduce students to solutions and crystal growth—and you can make it a tasty treat at the same time! This activity, which can be done at home using only 2 ingredients, helps students visualize how a supersaturated solution grows the extra-large crystals of sucrose needed to make rock candy. View »
  • Diffusion—Molecules on the Move Why not reverse the process for observing osmosis so that it has more of an inquiry-based approach? View »
  • Solve the Mystery Lab and Make a Silver Christmas Ornament Here's an activity that gets students in the holiday spirit while engaging their brains to solve a scientific mystery. View »
  • Equilibrium Straw Activity What is equilibrium? How is it reached? Many students assume that the concentrations or amounts of reactants and products—rather than rates—must be equal at equilibrium. This short lab activity helps to dispel that notion. View »
  • Ring and Disc Demonstration Gain a deeper understanding of the classic ring and disc physics demonstration designed to introduce the concepts of rotational inertia, rotational motion, and rolling motion. View »
  • Kool-Aid® Chromatography Students encounter mixtures every day though they may not realize it. Use this chromatography activity to teach an important lab technique and introduce or reinforce key science terms and concepts. View »
  • Electricity and Magnetism Electricity and magnetism are mentioned together so often they must be related. How are they connected? How can their relationship be used to make beneficial technology? Here’s a quick lab activity that can help your students find the answers to these questions. View »
