The water cycle is one of earth's most easily observable processes, but demonstrating each step within classroom walls can be a challenge. Through a series of videos and quick demonstrations, cover each aspect of the hydrologic cycle in...

It may be tricky for a young mind to conceptualize that less than 1% of all water on earth is useable for humans to drink. Simulating the amount of fresh water available on earth by removing measured amounts of water from a five-gallon...

Keep within a water budget. Learners find out that less than 2.5% of Earth's water is available to drink—and that there is a fixed amount of water. Scholars read an interesting article comparing the available water to a game of Monopoly...

Water temperatures connect to the movement of the ocean. Pupils read two articles about the temperature and the motion of the oceans before small groups investigate the interaction of hot and cold water. Team members add cold and hot...

What is the best way to test water quality? Using plastic bottles, scholars create monitoring sensors to test water quality. Creating three different sensors allows individuals to measure water quality at different water levels.

How do clouds form? Learners demonstrate the formation of clouds and the water cycle by testing four different setups in a plastic bottle. They identify the key components of a cloud to help them understand the process of cloud...

Pique interest in water pressure, demonstrate buoyancy, and explore water displacement concepts with a homemade Cartesian diver. You may want to change the name of the toy, however, as is is not documented the Rene Descartes...

Rainwater doesn't stay where it falls. Learners use modeling to demonstrate how rainwater disperses once it hits the ground. The activity includes an investigation of the height of the water table in an aquifer and how it is affected by...

Create jumbo bubbles and use them to teach about surface tension or interference, perfect for a physical science lesson on light or molecular attraction.

Model an oil spill cleanup. An engaging engineering lesson has groups using aerogels to simulate an oil spill cleanup (vegetable oil in water). Along the way, they learn about nanotechnology and hydrophilia/hydrophobia.

How do temperature changes affect ocean currents? Scholars explore convection currents by demonstrating the flow of water in a baking dish. They use ice, heat, and food coloring to see currents. Then, they draw conclusions about their...

Weathering is not necessarily a result of the weather. Scholars conduct an experiment to explore the effect of surface area and volume on the weathering process. They create their own sugar cube rocks using the same number of cubes—but...

There's no need to have friction among instructors regarding the resource. Pupils investigate how marbles and coins slide along different surfaces which gives them information to estimate coefficients of friction.

As part of a unit, this instructional activity familiarizes youngsters with components of a rain garden. They speculate about the role of an assigned component in contributing to a rain garden, and ultimately, in the health of the local...

Here's a lesson that is simply a-MAZE-ing! Introduce science scholars to pipeline systems through a hands-on project. Partnered pupils participate in the design, construct, and test a PVC pipeline maze. Reusable materials and clear...

Here is your go-to student resource on primary geography concepts, including facts about the surface of the earth and its hemispheres, latitude and longitude, globes, types of maps, and identifying continents and oceans.

Learners investigate how solar energy is converted into heat in part two of the 10-part Discover Your Changing World series. They build and test homemade solar cookers to boil water and cook rice. Pupils consider the impact of heat...

Our oceans are composed of many complex relationships. Young oceanographers explore relationships between organisms, understand the world ocean's currents, and discover the effects of water pollution and how it behaves. There are...

Mold your learners into materials engineers. Using glue, Borax, and water, scholars create a viscoelastic material. But your class might know it by another name—Silly Putty.

How is solar energy able to move wind and water to control the climate? Scholars explore the concept of solar energy in the first of 10 activities in the Discover Your Changing World series. They follow instructions to build homemade...

Maintaining a garden is an ongoing responsibility. This resource follows a series of activities in a unit that resulted in the planting of a rain garden. What you will find here are general instructions for watering, weeding, pruning,...

Will your next buoyancy lab rise to the occasion? Make a splash with action figure divers! Teams of young physicists explore the relationship between mass and buoyancy by adding weights or balloons to achieve a diver that neither sinks...

Get hands-on in your physical science class by having learners conduct electricity with their own hands! By placing one hand on each of two different metals, a current can be generated and measured on a microammeter. Make an experiement...

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