Ocean Water

Water with varying amounts of dissolved salt are dyed and then used to compare densities. The objective is to discover the effect of salinity, and therefore density, on ocean water on the stability of the ocean. Many branches of science...

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...

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...

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...

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...

Numbers and statistics don't mean nearly as much to middle schoolers as visuals. Create a model of earth's water supply with an aquarium, then follow the directions to remove small portions of the water to represent water in its various...

In this earth science activity, students complete 19 questions about oceans and the movement of ocean water in the form of puzzles, word scrambles, and brain teasers.

A video and laboratory investigation are highlights to this lesson on acidification of ocean water due to increased atmospheric carbon dioxide. Using bromothymol blue (BTB) as an indicator, pupils analyze the amount of carbon dioxide...

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...

The video clip that comprises the warm up is not available, but the related article from The New York Times and the movie trailer for Aliens of the Deep are, leaving enough material to make this a fascinating lesson on deep-sea...
