Getting the Big Picture: Reading the Ocean Stories Satellites Tell
Students learn how satellite images can be used to learn about ocean conditions and phytoplankton and learn to generate questions about ocean conditions, processes, and life.
Subject: Ocean Physics, Ocean Biology, Ocean Chemistry, Inquiry Grade: 6 - 12 Duration: 1 to 3 x 50 min
Ocean Literacy Principle: #3, #5, #7
Got Seaweed?
Learners explore seaweed samples. They use different criteria to sort the seaweeds, and then are guided to sort the seaweed based on color. Visitors also may observe what happens when powdered seaweed is mixed with water, and predict why we might add such seaweed products to food found in our cupboards. They then find out which foods do contain seaweed by checking the ingredients lists of some common foods.

Improving Oil Spill Response: Plotting the Currents in Prince William Sound
Students find and use data from the Alaska Ocean Observing System (AOOS) to plot the tracks of drifters used by scientists as real-time data to compare with computer predictions during a field experiment to test a circulation model for Prince William Sound, Alaska. They apply their knowledge to predicting the path of an oil spill and search & rescue.

The Carbon Cycle Game
A kinetic game in which students take a trip through some of the reservoirs of the carbon cycle. Students visit stations representing stops along the carbon cycle, collecting beads along the way. They then diagram and compare their journeys, learning about biogeochemical processes, photosynthesis and respiration.

What is in the Water?
Students will use open inquiry to learn about the process of science as well as gain experience regarding the Law of Conservation of Mass, dissolution, and density.
