  • What Goes On Inside a Spectrophotometer? A spectrophotometer measures the amount of light absorbed or transmitted as it passes through a sample, such as a solution containing food dye. Use this article to cover the basics of how a spectrophotometer works. View »
  • Sound Off Design a sound amplifier using different shapes and materials with this activity. Students should be familiar with the properties of sound waves and understand the definition of “acoustics.” View »
  • Carolina Investigations® for AP® Chemistry: Chemical Kinetics The order of a chemical reaction shows the relationship between the rate of chemical reaction and the concentration of reactant. View »
  • Science Isn't a Game! Well, Why Not? Have you considered online gaming as a new learning method? View »
  • Paper Clip Chemistry, Part 2 When you teach your students about chemical reactions, wouldn’t it be great if you could do it in such a way that you get great student reactions, too? Find out how everyday items such as paper clips and balloons can provide engaging, interactive lessons on chemical reactions and the ideal gas law. View »
  • Egg-cellent Chemistry: How to Marble Eggs Decorating eggs is a fun and memorable way to illustrate scientific concepts and make real-world connections. This egg-speriment is appropriate for either the kitchen at home or the laboratory at school. View »
  • Hot and Cold Packs: A Thermochemistry Activity A discussion of chemical hot and cold packs can really warm up a classroom lesson on thermochemistry. In this hands-on activity, students use a coffee cup calorimeter to measure the heat of solution of a chemical salt using 3 different masses and then design their own hot and/or cold pack. 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 »
  • The Physics of Vision Get ready to investigate parallax and depth perception with 2 activities you can complete in less than 30 minutes. View »
  • Carolina Quick Tips: Boats and Buoyancy This activity will help reinforce students' knowledge of engineering and principles of density and buoyancy. View »
  • AP® Chemistry: Scientific and Technical Writing A good method for honing writing skills is to edit another’s work. This activity includes 2 AP® test question responses for students to rewrite. View »
  • Paper Clip Chemistry You know you can count on paper clips to hold your important papers together, but did you know you can use paper clips to teach chemistry concepts too? Give students a hands-on, interactive way to explore measurement, matter, and atomic structure with the activities described in this article. View »
