Classroom Activities

  • 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.

  • Photosynthesis Modeling with Pop Beads While studying photosynthesis, students can have difficulty understanding how the carbon in CO2 becomes the carbon in glucose. Use this activity to clarify the process. View »
  • Making Algae Beads In this activity students create spheres of green algae for use in experiments that explore the metabolic processes of plants. Includes a materials list and step-by-step instructions. View »
  • Using Algae Beads as a Model for Photosynthesis Introduce students to photosynthesis with fresh water algae. By creating algae beads (made of algae and sodium alginate solution), they indirectly observe the change in concentration of oxygen in beads that are exposed to different amounts of light. View »
  • Photosynthesis Introduce students to photosynthesis in a visual way. As Elodea uses carbon dioxide from an initial solution, a change in pH occurs, causing a color change in the solution. View »
  • Hydroponic Nutrient Solution After a structured investigation of a hydroponic technology, students design an experiment to test different nutrient solutions. View »
  • Calorimetry: Measuring the Energy in Foods In this investigation, students determine the calories, or heat content, of 3 different foods. View »
