Investigating Convection Currents

Environmentalists test stream water for temperature, pH, and turbidity. Each group shares their information and then the class makes an overall evaluation of the water quality. A slide show sets the backdrop for the teaching portion and...

Is your current lesson plan for salt and freshwater literacy leaving you high and dry? If so, dive into part one of a seven-part series that explores the physical features of Earth's salt and freshwater sources. Junior hydrologists...

Students investigate the water cycle by performing a simple hands-on activity using a plastic container, plastic cup, a rock, and a reflector lamp. They observe the model and measure the water level from time to time.

How does heat move from one item to another, even when the items are in different states of matter? Pupils experiment with adding washers to hot water and adding hot washers to room temperature water to observe the heat transfer. 

Open learners' eyes to the challenge of finding safe drinking water – something we often take for granted in our country. The PowerPoint presentation includes images, graphs, diagrams, and even a video to stimulate discussion on how we...

Environmental explorers examine the campus and take note of living organisms. Introduce them to the biosphere and the questions of the day: How much water can be found in the biosphere? A slide show helps you along, and even contains a...

Take young scientists on a trip through the water cycle with this interactive science activity. After setting up a series of ten stations representing the different places water can be found, children use the included printable dice to...

Your class sets up a mini water cycle model to examine the process. Then they watch an animation, following a water molecule through the cycle. A well-developed lab sheet guides learners through the lesson and a PowerPoint presentation...

Through a PowerPoint presentation and the embedded animation and video, earth science enthusiasts find out about the moisture in the soil beneath our feet. In the animation, follow a water molecule on its path through the water cycle. As...

What drives the ocean's motion? Get your class moving toward understanding by using this video. Viewers find that thermohaline circulation is caused by the concentration gradients of temperature and salinity. Using adorable animation in...
