Properties of the Ocean: Change

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...

It's time for your class to literally show what they know! Pupils illustrate what they learned about the causes and effects of climate change by filling out a graphic organizer to complete the 5-part series of lessons. They discuss them...

Students analyze the impact of climate variability and change utilizing a broad span of topics over a wide range of grade levels. This three instructional activity unit is easily adapted for the various instructional levels listed.

Global warming isn't just an issue on land; deep ocean waters are also showing troubling signs. Young scientists learn more about deep water corals and the many recent discoveries researchers have made. Then they examine data related to...

It's time to mix things up! Introduce biology scholars to the latest topic in marine research—invertebrates! The third installment in a five-part series of Invertebrates lessons explains the hypothesis that tiny, migrating shrimp are...

What does it mean when scientists say the earth is warming? The second video in a seven-part series explains how scientists measure the temperature of the entire Earth. It links to factors that affect climate change through discussions...

Young scientists explore climate change by taking a look at many different disciplines. They hear from scientists who study soil, clouds, ice cores, ocean temperatures, and more. Then, they search public databases to draw their own...

Test the class's knowledge of the key components of climate change. A 10-question online quiz asks learners about weather, climate, greenhouse gases, and several other concepts related to climate change. Interactive and easy for...

Show the six-minute video, "Changing Planet: Fading Corals," and then demonstrate how calcium carbonate forms a precipitate in the presence of carbon dioxide. Separate your scientists into small groups to gather information about coral...

Students sample goodies from an unseen ocean floor and try to accurately describe their composition. This simulation helps students explain the limitations of sampling and the problem of obtaining representative samples of sea floor...
