  • Carbon Snake In this teacher-directed demonstration of an exothermic reaction, students observe the dehydration of a carbohydrate using concentrated sulfuric acid. View »
  • The Problem with Pulleys Build and test working models of pulley systems commonly used in problems in physics texts and tests. View »
  • Food Calorimetry: How to Measure Calories in Food Help your students learn how to determine the calories in food with this hands-on lab activity. Using common, inexpensive materials, students construct a calorimeter and test several food samples to determine their energy content. Addresses selected National Science Education Standards for grades 9–12. View »
  • What's the Big Idea? Understanding the Laboratory Experience in the AP* Chemistry Curriculum If you teach AP* Chemistry, you’re already aware, or need to be, that changes to the course curriculum are here, which means you’ll probably have to change your classroom instruction. To help relieve your anxiety, here’s an overview of the course revisions, some important dates to remember, and 2 ways Carolina can help to ensure your success during this transition. View »
  • Activities with UV Beads Ultraviolet-sensitive beads change color when exposed to ultraviolet (UV) light. They are inexpensive, yet give students a way to detect the presence of UV light, which is normally invisible to humans. Here are 2 inquiry-based activities that enable students to investigate UV light using these remarkable beads. View »
  • Infographic: Simple Machines This infographic profiles four of the six simple machines: inclined plane, pulley, lever, wheel and axle. View »
  • Heat Transfer Between Components of a System This easy, inexpensive lab demonstrates the transfer of heat energy from a higher temperature substance to a lower temperature substance within the same system. View »
  • Thermochemistry: An Endothermic Reaction In this thermochemistry demonstration, students observe an extreme, spontaneous endothermic reaction between 2 solid compounds, measure changes in temperature, and make observations. View »
  • Energy Transformations in a Dark Detector This activity is designed to give students the opportunity to design, build, and test a dark detector circuit. A dark detector is a simple circuit that can be used to explain the function of a light-dependent resistor and a transistor, two common electrical components. View »
