Einstein's Big Idea
Students create a time line of scientists involved with E = mc2. They describe experiments that led to an understanding of energy, mass, the speed of light squared, and the equivalence of mass and energy. Students relate challenges...
Curated OER
Canned Heat
Pupils demonstrate that light and dark colored objects absorb the sun's radiation at different rates. They experiment with the temperature change of water in two locations and discuss the results.
Curated OER
What Makes a Healthy Plant?
Students predict the effects of water, light, and soil on the development of a plant and then design an experiment to test their predictions.

Photosynthesis
In this biology worksheet, students explain where the energy of food originally came from. Then the explain one of the principal chemical compounds that living things use to store energy. Students also describe how ATP and ADP differ and...
Curated OER
Bioluminescence
Students discover the concept of bioluminescence. They identify marine animals who have use this and why. They work together to test the function of bioluminescence as camouflage.
Curated OER
Infrared-Hot
Students describe how the sun heats the Earth, explain the nature of infrared light, explain how thunderstorms are formed and use infrared maps to predict severe weather.
Curated OER
Seeds & Germination
Students study the types and parts of seeds and how they have evolved. In this germination lesson students complete experiments that show the effects of variables role in seed germination.
Curated OER
The Sun in Our Lives
Third graders identify the different parts of the sun. In this astronomy lesson plan, 3rd graders examine how the sun's energy drive life processes on Earth. They construct a model of a solar system using large rolls of toilet paper.
Curated OER
Exploring Forest Objects
Young scholars explore the forest. In this ecosystems lesson, students rotate through sensory activity centers, brainstorm, and read about temperate forests.
Curated OER
The Dirt on Plants
Students draw and label the four parts of a plant. They describe changes that are part of the common life cycle. Students follow various one and two step directions. They are asked to discuss that they can recall about plants.
Curated OER
Stellar Spectral Fingerprints
Pupils listen as the teacher introduces Newton's early discovery of the diffraction of light. They use multiple sources of light (fluorescent, incandescent, sunlight, etc) to bend the light. They first use a prism then a diffraction...
