  • Where's the Fat? In this activity, students learn extraction procedures by separating fat from a snack food. They analyze the effectiveness of their chemical extraction procedure by comparing actual results with their predicted results. 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 »
  • Simulating Succession Ecosystems Activity Student groups create tiny ecosystems in glass culture tubes and observe the succession of organisms within them. Extension activities and discussion questions help students further explore the concept. View »
  • Hydroponic Nutrient Solution After a structured investigation of a hydroponic technology, students design an experiment to test different nutrient solutions. View »
  • MOM's Acid-Base Chemistry You don't need a tummy ache to experience the benefits of MOM (milk of magnesia). It's also strong medicine for teaching acid-base chemistry, chemical equilibrium, heat of equalization, and Le Châtelier's principle. View »
  • Demonstrating Cellular Respiration and Fermentation Use this demonstration to show the big picture of aerobic cell respiration (with germinating seeds) and fermentation (produced by yeast). View »
  • Plant Biodiversity Field Activity This field activity introduces students to biodiversity through the study of plants and animals in a designated area. But here’s the twist—instead of using a quadrat to designate the area of study, students use a Hula Hoop® instead. View »
  • Penny Skins Find out exactly what a penny's made of with this quick and easy activity that can be used for elementary, middle or high school students. View »
  • On the Cutting Edge: Think Mink! This article explores how Carolina mink make great model organisms for introducing your students to general mammalian anatomy and physiology. View »
  • Exploring Air Resistance Investigate the relationship between velocity and air resistance. 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 »
  • Which Leaf Shape Can Hold the Most Butterfly Eggs? In this elementary-level activity, students investigate the relationship between leaf shape and the number of butterfly eggs that can be laid on a leaf (grades K–5). View »
