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...

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...

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...

Fifth graders explore the major components of the water cycle. They pay close attention to evaporation, condensation, and precipitation. A water cycle kit is set up in the classroom, which learners observe for a couple of days before the...

In this earth science worksheet, 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...

Sixth graders experiment to understand the ocean's currents.  In this ocean current lesson, 6th graders complete an experiment with two bottles of water and an index card to discover information about the ocean current.  Students...
