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 »
  • 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 »
  • Plate Tectonics Activity Here is a fascinating activity that will help you give your students a better understanding of Earth's structure and how it creates tectonic plate movement. 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 »
  • Chemoween and Other Spooky Science Treat your students to some spirited demos and hands-on activities, and celebrate Halloween as the finale to your October science explorations. View »
  • Volcano in the Classroom Here’s a safe, easy, and vivid interpretation of a classic activity that won’t break the budget. All you’ll need are a few common items—a beaker, sand, water, a candle, and a hot plate. View »
  • Air Pollution: Tropospheric Ozone, Particulates, and Indoor Carbon Dioxide "Bad" ozone, dangerous particulates, and significant CO2 buildup—in and around your school! Access a series of field tests students can use to measure your school’s tropospheric ozone levels and the number of deposited particulates in different locations, and to study how carbon dioxide concentrations indoors vary throughout the school day.

  • Invasion! Invasion! Engage life science students by investigating a fascinating topic: invasive species. Here’s a lesson plan outline to help you get started. Based on the KWL chart, it guides you through 4 days of invasive species activities that introduce the topic, guide research, and culminate in a research project. View »
  • The Lava Lamp Lab: A Guided-Inquiry Approach to Intermolecular Forces Remember that lava lamp you had? You and your students can use this lab to explore the fascinating world of intermolecular forces firsthand. 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 »
  • Chemistry Holiday Hoopla! If the approaching holidays are causing student minds to wander, try these holiday-oriented demonstrations to recapture their attention. The activities acknowledge the season while helping students understand important chemistry concepts. 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 »
  • Schoolyard Field Study Conduct a field study of your schoolyard with this activity. It’s an opportunity for students to apply what they’ve learned throughout the year. Students work in groups of 2 to 3 over several class periods. 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 »
  • AP® Biology: Statistics Worksheet A set of 4 problems focused on statistics and analysis. View »
  • Evaluating a Scientific Claim: Evaluating Lemonade as a Buffer Students can use this graphic organizer to evaluate a scientific claim about adding buffers to medicines. View »
  • Thermochemistry: An Endothermic Reaction In this thermochemistry demonstration, students observe an extreme, spontaneous endothermic reaction between 2 solid compounds, measure changes in temperature, and make observations. View »
  • Carbon Snake In this teacher-directed demonstration of an exothermic reaction, students observe the dehydration of a carbohydrate using concentrated sulfuric acid. 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 »
