COLD SEA WATERS

Investigate how temperature affects the density of water and stratification that occurs in bodies of water when temperatures vary. Water of differing temperatures is given different colors to see the layers that form. The lesson is meant...

In a cross-curricular lesson linking math and science, examine the percentages of earth's water supply with your elementary kids using pasta or dixie cups of water. Younger learners focus on identifying local water sources on the globe...

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...

Scholars find Earth won't support humans much longer and need to identify a planet with water to inhabit. They test four unknown samples and determine which is the closest to water. Then they explain and defend their results.

Students investigate the role of temperature and salinity in determining seawater density. They use a Temperature-Salinity Diagram to examine the effects of mixing on density.

Students observe how salinity affects the time it takes water to freeze. They participate in an experiment to determine that ice is essentially salt-free whether formed from fresh or salt water

Ice is nice, and its condition on the planet has a significant effect. Junior geoscientists experiment with ice melting in both water and on land to discover how each affect the rising sea level. This detailed lesson outline even...

How is it that water that falls as rain ends up coming out of the tap on our sinks? Learners trace water's journey and examine how along the way pollutants make their way into the water supply. They conduct experiments, use the Internet...

Young scientists examine how even a small rise in sea level can lead to salinisation of valuable agricultural land. First, everyone takes part in a simple demonstration which shows the negative effects salt water has on plants. Peer...

With the global temperature on the rise, the effects of climate change are starting to be seen. However, many people have a difficult time conceptualizing the long-term effects, such as sea levels rising. Given an easy and effective...
