Physical Science

  • Newton's Law of Cooling Confirm Newton's law of cooling by collecting and analyzing data on samples of water undergoing a temperature change. View »
  • Balancing Chemical Equations Having your students balance chemical equations aids their understanding of conservation of mass. In this activity, students build models to "see" what happens on both sides of the equation. View »
  • Signs of Chemical Changes: Testing for CO2, O2, and H2 Help students master techniques for testing and identifying hydrogen, oxygen, and carbon dioxide gas while developing a reaction model. View »
  • Teaching Chemistry with Manipulatives Manipulatives can help students (especially visual and tactile learners) understand abstract concepts by allowing them to “see” a chemical structure or process. We offer 2 ideas for creating manipulatives and how to use them. View »
  • Red Cabbage Juice: A Homemade pH Indicator! In this activity, students make a pH indicator from red cabbage juice and then use it to test various substances. View »
  • Classifying Chemical Reactions Learning 5 basic categories of chemical reactions helps chemistry students with the essential skill of writing and balancing chemical equations—and boosts their ability to predict reaction products when only given reactants. 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 »
  • 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 »
  • Buoyancy, Hardness, and Magnetism How do the properties of materials make them suitable for some uses and not others? Students investigate that question with this activity adapted from an investigation in the Building Blocks of Science® unit Structure and Properties of Matter. Students get to observe, classify, and categorize different materials. View »
  • Basic Lab Equipment Needed for a Physical Science/Physics Lab Use this helpful guide to ensure you outfit your physical science/physics lab with essential equipment and supplies. View »
  • A Visual Introduction to Ionic and Net Ionic Equations With this activity students explore the phenomenon of chemical precipitation and construct an atomic level model of precipitation using ionic and net ionic equations. 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 »
