Astronauts train underwater to simulate the change in gravity. An out-of-this-world unit includes three hands-on activities, one teacher demonstration, and a discussion related to some of the challenges astronauts face. Scholars apply...

Roll up your sleeves and get a little dirty with this elementary and middle school compost instructional activity. All you need is a large plastic container, a couple old newspapers, some organic waste, and a few hundred worms and...

Lead your class through the amazing world of isotopes as they investigate the various properties they contain and further understand their respective location on the periodic table. They explore half-lives and radioactivity as each...

By rolling marbles down a six-foot length of track, physical scientists determine how much energy is lost to heat. It is recommended that you opt for the foam pipe insulation track because more friction slows the marble, allowing...

This science assignment produced by NASA teaches inquiring minds the distribution of Earth's water. Learners will appreciate and understand the importance of fresh water and how weather and climate affects everything.

Introduce your earth science enthusiasts to the earth's energy budget. Teach them using an informative set of slides that include illuminating lecturer's notes, relevant vocabulary, embedded animations, colorful satellite maps, and a...

Crawl into the world of the darkling beetle with this scientific investigation. Watch as the insects move through the larval, pupal, and adult stages of life, recording observations along the way. Discuss the necessities of life as young...

How are chemical reactions affected by gravity? Learners explore the phenomenon of effervescence as part of the Christa's Lost Lessons series. They compare findings in an experiment on effervescence to a video of a similar experiment in...

Energy conservers investigate gravel size to discover if it impacts the amount of oil recovered in the extraction process. 

What is reflectivity, and what does it have to do with the Earth's climate? As reflectivity is measured by albedo, scientists can gather information on Earth's energy balances that relate to global warming or climate change. Budding...

Scientific procedures ensure valid data and valid results. Use a water sampling interactive to teach learners the procedures for collecting water samples. The interactive takes users through the process step-by-step with notes of...

Young scientists use electrolysis to separate water into its elements before experimenting with fire to learn about their properties. A helpful resource provides a reading passage and analysis questions. 

Ice is nice, and its condition on the planet has a significant effect. Junior geoscientists experiment with ice melting in both water and on land to discover how each affect the rising sea level. This detailed lesson outline even...

How do astronauts know how to live and work in a weightless environment? It doesn't come naturally! Junior physicists conduct experiments to examine the link between buoyancy and microgravity. Each activity illustrates a different aspect...

How does sound travel through different mediums? Scholars explore this question by creating and observing sound waves as they learn the difference between transverse and longitudinal wave motion. Using their new knowledge, class members...

Young classes are sure to get a charge out of this lesson! Learners experiment with circuits of a solar cell. They practice determining current, voltage, and power for the circuit and maximize the voltage and current of the cell.
