In this activity, learners examine body parts (including skin, scales, and skulls) from fish, mammals and reptiles. Questions are provided to help encourage learner investigations.
In this activity, learners investigate how wind can create surface currents and how waves move. Learners also discover how wind can affect oil spills.
In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.
In this lab activity, learners explore how to initiate a density current. Learners measure six flasks with different concentrations of salt and water (colored blue).
In this activity (on pages 18-29) learners explore the impact of the March 24, 1989 oil spill in Alaska caused by the Exxon Valdez tanker.
In this activity, learners discuss the different salinities of oceans, rivers and estuaries.
In this collecting/comparing activity, learners work with samples of sand from different places like a lakefront, river, or ocean beach.
In this activity, learners explore how salt water freezes in comparison to fresh water.
In this activity, learners work in small groups to match various marine animals with their different environments.
In this activity, learners use whale count data from the Hawaiian Islands Humpback Whale National Marine Sanctuary to compare whale counts in relation to environmental factors.
In this activity, learners explore how acids can dissolve eggshells leaving behind a membrane-covered bouncy egg.
In this data activity, learners will compare and contrast fish communities, diversity and habitats in U.S. National Marine Sanctuaries.
Ocean acidification is a big issue due to the amount of carbon dioxide humans release. CO2 in the atmosphere is absorbed into the ocean thus changing its acidity.
In this creative roleplay activity, learners will explore the various processes of the water cycle using movement, sound, and props to aid in comprehension.
In this group activity, learners act out key stages of the "ocean carbon cycle" (also known as the "carbonate buffer system") through motions, rearranging blocks and team tasks.
In this activity, learners observe live fish in tanks to consider how their body structures are related to their behaviors and habitats.
Throw that fish back? A new generation of ethical anglers concerned about conserving resources is participating in "catch and release" fishing. How is this going?
In this activity, learners observe tide pool animals in a touch tank to consider how they survive.
This creative lesson plan provides a visual way for learners to gain knowledge about the finite amount of fresh water on Earth and encourages the discussion of the various ways to conserve this resour
