Skin, Scales and Skulls
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.
Blowin’ Up a Storm of Oil
In this activity, learners investigate how wind can create surface currents and how waves move. Learners also discover how wind can affect oil spills.
Salt 'n LighterAdd to list Details
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.
Investigating Density Currents
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.
Water Body Salinities II
In this activity, learners discuss the different salinities of oceans, rivers and estuaries.
Sandy SamplesAdd to list Details
In this collecting/comparing activity, learners work with samples of sand from different places like a lakefront, river, or ocean beach.
Why Doesn’t the Ocean Freeze?
In this activity, learners explore how salt water freezes in comparison to fresh water.
Habitat Adaptation MatchupAdd to list Details
In this activity, learners work in small groups to match various marine animals with their different environments.
Let's Count Humpback Whales: Environmental Effects on PopulationAdd to list Details
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.
Fish Communities: National Marine SanctuariesAdd to list Details
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.
Amazon Water Cycle RoleplayAdd to list Details
In this creative roleplay activity, learners will explore the various processes of the water cycle using movement, sound, and props to aid in comprehension.
Coral, Carbon Dioxide and CalcificationAdd to list Details
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.
Fish Features and HabitatsAdd to list Details
In this activity, learners observe live fish in tanks to consider how their body structures are related to their behaviors and habitats.
Catch & Release II: It's Catching On!Add to list Details
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?
Tide Pool Survival
In this activity, learners observe tide pool animals in a touch tank to consider how they survive.
Earth's Water: A Drop in Your CupAdd to list Details
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
A Scientific CleanupAdd to list Details
This is a comprehensive lesson plan on page 85 for a group cleanup trip to a local beach, lake or stream. Learners keep track of the types and amounts of trash picked up and analyze this information.
