Physical Science

  • 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 »
  • Cooling Diagram for t-Butanol Help students understand the relationship between energy and the phase changes of a pure substance with this deceptively simple activity. View »
  • How to Keep the Science in Booms and Bangs and Other Demos We'll show you how to do an "explosive" chemistry demo and use the 5E learning cycle to ensure your students get the science behind it. View »
  • Force Awakens Magnetism is an example of a non-contact force that occurs when objects are not touching. In this activity, students investigate how magnets create a force field that can attract and repel objects. Includes a materials list and step-by-step instructions. 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 »
  • 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 »
  • Three Little Salts When 3 seemingly identical white salts are dissolved in water, 3 strikingly different results occur. Use this simple experiment to teach your students about thermochemistry, chemical and physical changes. View »
  • 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 »
  • Basic Lab Equipment Needed for a Chemistry Lab Use this helpful guide to ensure you outfit your chemistry lab with essential equipment and supplies. View »
  • Teaching Hardy Weinberg in the classroom In order for allele and genotype frequencies to remain stable in a given population, certain conditions must be met. But what happens when these conditions aren’t met? Help your students understand the Hardy-Weinberg principle by modeling a population of edible treats. View »
  • Everyday Magnetism Learn about magnetism in this activity. View »
  • Carbon Snake In this teacher-directed demonstration of an exothermic reaction, students observe the dehydration of a carbohydrate using concentrated sulfuric acid. View »
