Energy for Life (Energy from Food)
Energy comes in many forms, but how do living things get the energy they need to survive and thrive? In a simple, controlled experiment with yeast, water, and sugar, groups make observations about how yeast reacts with water alone, then...
PHET
Bending Light
Different colors of the spectrum travel at different speeds through media, causing them to refract at different angles—which allows humans to see their colors. Through a simulation, pupils see how air, water, and other media bend light....
Curated OER
Emission Spectra
These attractive slides explain the basics of the electromagnetic spectrum and then display the emission spectra for a number of elements. argon, helium, hydrogen, xenon, neon and krypton are shown here and two graphs showing log scale...

Density: Sink and Float for Liquids
We don't think of liquids as floating typically, but a quick look at any oil spill tells a different story. Lesson explores various densities of liquids and why this fact is important. After observing the density variation, scholars...
Curated OER
Clean, Green Power
Students explore and discuss alternative energy sources, and identify disadvantages of current fossil fuels.
Curated OER
Life on the Ocean Floor
Why would water 2700 meters deep suddenly become warmer? Explore this and other ocean floor discoveries through this reading response worksheet. Scholars read information about the organisms discovered by Alvin, a deep-sea submersible....
Curated OER
Catch a Wave
Students study low tides and how to calculate for fresh water. In this ocean science lesson, students pretend they are stranded on an island and must calculate low tide in order to source the fresh water aquifer. Students calculate how...
Curated OER
Plumbing the Deep-Using Sound Waves to See
Young scholars explore and learn about the concept of echolocation. In this echolocation lesson, students explore how animals and engineers use echolocation (seeing under water) and sound waves to look and hear things under the deep water.
Curated OER
Light Can Heat Too!
Third graders explore absorption and reflection of light energy. In this solar energy lesson, 3rd graders explore how light energy transfers to heat energy through the construction of a solar water heater. Students will discuss and...
Curated OER
Groundwater Movement
Students study groundwater movement beneath the surface of the Earth. In this agriculture lesson, students experiment with how water moves through rock materials such as sand, gravel, and clay.
Curated OER
Designing an Ecologically Sound City
Fifth graders design an "ecologically sound" city. They write laws for the city to help make all citizens aware of their ecological responsibilities and propose alternative power sources for light and heat.
Curated OER
Soil Nutrients - Phosphorus Lab Lesson Plan
Students list sources of phosphorus in soil. They explain how phosphorus is removed from the soil and used by plants. Students list the symptoms of insufficient or excess phosphorus. Students perform experiments to examine the effect of...
