Physical Science

  • Violet Shines Blue Classic demo with a violet laser pointer may be used as a discrepant event to discuss light waves, fluorescence, or chemical quenching. View »
  • Petri Dish Electrolysis Activity Introduce your students to reduction-oxidation reactions and some of the basic terms of electrochemistry (such as electrode potential, anode, and cathode) with this activity—creating electrolysis in a petri dish. View »
  • Bending Light Light travels in a straight path. Find out how get light to “bend” and follow a curved stream of water! View »
  • Teaching the Scientific Method with Effervescent Tablets In this activity, students learn the scientific method by practicing it. After a thorough introduction to the topic, students participate in an endothermic reaction experiment illustrating each step in the scientific method. 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 »
  • 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 »
  • Understanding the Periodic Table Looking for inexpensive ways to help students understand and appreciate how much information the periodic table provides? In these 2 activities, students discover for themselves several trends associated with the elements on the periodic table. View »
  • Chemistry Solutions Practice Problems Refresh your students' knowledge of molarity with these practice problems. View »
  • Nomenclature and Bonding Basics of Ionic Compounds Here are two simple activities that can help students identify and name compound types. These activities are designed for high schoolers and address several National Science Education Standards. View »
  • A New Approach to Teaching Atomic Theory For chemistry teacher Siobhan Julian, teaching the history of atomic theory by lecture “was dry and tedious and boring for everyone involved.” Then she took a fresh approach—one that focuses on doing science to learn science history. View »
  • Simplifying Circuits In this activity, students build and test various circuits while investigating how electric circuits work. View »
  • Let's Do S'more Chemistry! Your students can learn, have fun, and eat it, too! This laboratory activity explores the topics of stoichiometry and limiting reactants in a fun, delicious way. If you perform this activity with food products—which we highly recommend because making and eating the S’mores is a great way to cap off the activity—do so only in a dedicated classroom. View »
