Learners explore hurricanes and tornadoes by conducting an experiment. In this weather pattern instructional activity, students define many extreme weather vocabulary terms and discuss the relationship with static electricity. Learners...

Students study the nomenclature, operation and purpose of America's Space Transportation system. They demonstrate how water can be broken down into its component gases of hydrogen and oxygen by electrolysis. They construct and use the...

Second graders explore weathering and how the water cycle plays a part in weathering. In this weathering lesson, 2nd graders put gravel and sugar cubes in a jar and shake, simulating weathering. Students use the scientific method to...

Students examine how water is treated prior to becoming available for human consumption. In this water treatment lesson, students conduct an experiment in which they filter water. Students formulate a hypothesis, test, analyze data, and...

Young scholars explore the carbon cycle. In this carbon cycle lesson, students discuss the four main reservoirs where carbon is stored and then discover the process through which each reservoir absorbs and releases CO2. This lesson...

Students explore marine life by conducting a rubber duck experiment. In this water currents lesson, students practice identifying latitude and longitude coordinates on a map and define the currents of major oceans. Students discuss the...

Learners explore winter adaptations and glare. In this winter weather lesson, students discuss the season of winter and how animals and plants adapt to the changing weather. Learners discuss the glare off snow and make goggles for their...

Learners explore the ecosystem by conducting a ziploc bag experiment. For this recycling lesson, students identify decomposer organisms in our environment and how they speed up the recycling process. Learners utilize a ziploc plastic...

Young scholars explore the weather system by analyzing water properties. In this precipitation lesson, students review weather related vocabulary terms and discuss how rainbows are created by light hitting droplets at the right time....

Students explore how sewer systems can contribute to water pollution and perform an experiment to see how well a water purification technique can protect against water-born microbial illnesses. They compare the bacterial growth from...

Students are taught that plants produce oxygen underwater, and they design an experiment that test this question. They discuss whether plants give off oxygen, and how to measure this. Students measure the increase in dissolved oxygen...

Drawings of four groups of soil particles of varying sizes are displayed across the page for soil scientists to examine. As they complete the worksheet, place a set of similar soils at each table for hands-on experience. In this way,...

Students construct a volcano using baking soda and vinegar. In this earth science lesson, students explain the reaction that takes place when these two chemicals combine together.

Scientists need to figure out how to measure interplanetary magnetic fields, but the magnetic field of the spacecraft is interfering with their readings. Scholars attempt to solve the problem that has perplexed NASA scientists for years.

Young scientists learn how to select a scale factor for a large scale model. Then they figure the scale for each of the planets and the distance between them. Finally, they construct a giant scale model of the solar system and answer...

Every year we discover new planets including more than 1,000 in 2016 alone. Will we ever find life on another planet? The lesson includes two activities to help scholars understand this concept. First, they analyze the temperature range...

How can you provide healthy soil for your garden? Study worms, bacteria, and other microorganisms in a lesson about decomposition and organic compost. After discussing what you know about worms and watching a video, watch what worms do...

Which is worse — drought or flooding? Neither is helpful to the environment, and both are increasing due to climate change. The 16th instructional activity in a series of 21 covers the average precipitation trends for two different...

Fourth graders explore the three layers of the Earth describing the composition, thickness, and temperature of each layer. Layers are compared and contrasted and data unearthed placed into graphic organizers.

Third graders utilize technology to access, analyze, interpret and communicate information about Earth Day.

Learners explore the skills and information needed to complete a science fair project. They follow guidelines to create an document their science fair project.

Students identify the concept of an element and work with an idea that all of the millions of substances on the earth are various combinations of only 8 elements. They work with the Periodic Table of the Elements and symbols of the...
