Classroom Activities

  • Estimating Populations Using Mark-Recapture Mark-recapture is one of the most common methods used by ecologists to determine population size. Engage your students with this exciting activity to get hands-on experience with the Mark-recapture method. View »
  • Flipping Molecular Structures The flipped classroom model often starts with replacing whole-class lecture time with traditional homework and using video podcasts to get the notes done in the individual learning space. Few teachers who flip their classes successfully stay in this mode for very long. View »
  • Freezing Point Depression Activity: Ice Cream Spring brings showers, sunshine, and the prospect of summer break. Celebrate with this cool, fun activity. It requires just a few inexpensive materials and can be the basis of an engaging lesson on colligative properties. 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 »
  • 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 »
  • Science Notebook: An Owl Pellet Inquiry This introductory owl pellet dissection is a springboard for teaching the techniques of using a science notebook while having students engage in the scientific practices. View »
  • Teaching with Ecosystem Aquariums By creating and maintaining an aquarium ecosystem in the classroom, students can understand the web of relationships that link organisms to one another, and they can develop a growing sensitivity to living things and what they need to survive. 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 »
  • Kool-Aid® Chromatography Students encounter mixtures every day though they may not realize it. Use this chromatography activity to teach an important lab technique and introduce or reinforce key science terms and concepts. View »
  • Copying Nature’s Success: Teaching Students About Biomimetics Ready to create a model home that draws on biomimetics? In this activity, students research, design, and build structures that incorporate ideas inspired by the natural world. View »
  • Two Quick, Easy Ways to Collect Insects for Diversity Studies Get your students outside and engaged with the world around them. In this activity, we’ll look at 2 techniques that make collecting insects in the field quick and easy. Use one or both to collect insects from microenvironments around your school and then examine diversity using Shannon’s or Simpson’s diversity index. View »
  • End the Year with an Outdoor Classroom Everything’s better in the great outdoors. Celebrate the warmer weather and engage your students during the final stretch of the school year with these fun activities. View »
  • One in a Million: Using Serial Dilutions to Understand Concentration In this activity, students will learn about concentration while performing a serial dilution. View »
  • Fractional Distillation of a Carbonated Soft Drink How is crude oil refined into many valuable products? Students can find out with this lab activity. Substituting a soft drink for crude oil, they use fractional distillation to separate the soft drink into its components, or fractions. View »
  • Carolina Quick Tips®: Paper Chromatography of Pens and Acid-Base Indicators In this activity, students use paper chromatography to separate the components of black ink in pens and of an acid-base indicator solu- tion. View »
  • Urban Stream Syndrome Urban streams often suffer from urban stream syndrome, which is characterized by changes in nutrient levels, hydrology, biodiversity, and other factors. In this activity, students learn how to identify streams that suffer from urban stream syndrome based on visual evidence. View »
  • Invertebrate Biodiversity and Abiotic Factors Understanding the relationships between biotic diversity and abiotic factors in an ecosystem can be a difficult task. Using soil invertebrates, students can identify both the number of species present in a soil sample and the number of individuals within a species. View »
  • Pill Bug Behavior Choices This introductory investigation into animal behavior uses pill bugs and choice chambers. Students begin with an experiment to test how pill bugs respond to humidity and can go on to design an inquiry to test another environmental factor. 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 »
  • Elephant Toothpaste This demonstration showing the decomposition of hydrogen peroxide, catalyzed by iodide ions, provides students with visual evidence of a chemical reaction. View »
