Observing Salinity Patterns
Stephanie Jaeger, Green River Community College
Part 1: Students measure the salinity of samples using a refractometer, and consider the units and density of these values. Part 2: Students apply concepts and reinforce what they've learned about salinity and ...
Seasonal variation in light, mixing depth and primary productivity in temperate northern hemisphere waters
Lauren Sahl, Maine Maritime Academy
In this exercise students work with light, temperature, and phytoplankton biomass proxy (chlorophyll a concentration) data to; Become more skilled in reading and interpreting semi log graphs, temperature profiles, ...
Getting a Grip on Hydrogen Bonds
Elizabeth Nagy-Shadman, Pasadena City College
The purpose of this brief (~15 minutes) activity is for students to directly observe some of the unique properties of water that are the result of hydrogen bonds, such as capillary action, adhesion, cohesion, and ...
Petra Dekens, San Francisco State University
This is an in-class activity designed to improve the students' understanding of the relationships between temperature and density, salinity and density, and density differences in driving vertical water ...
Seawater composition: an introduction
Joceline Boucher, Maine Maritime Academy
In this activity, students collaboratively "build" the hydrologic cycle and use it as a starting point for thinking about the composition of seawater.
Deep water circulation and chemistry jigsaw
Michele LaVigne, Bowdoin College
This activity is designed to introduce students to the way in which thermohaline circulation and the biological pump influence the distribution of nutrients, oxygen, carbon, and radiocarbon in the Atlantic vs. ...
Changing With the Tide
Rebecca Teed, Wright State University-Main Campus
This lesson plan is written around a brief role-play in which students learn about and act out plants and animals in a salt marsh habitat as the tides change. -
ConcepTest: Drivers of Ocean Salinity Variations
Imagine ocean circulation stopped suddenly, with half of the world's salts in the northern hemisphere and half in the southern hemisphere. Assuming no net difference between evaporation and precipitation ...
ConcepTest: Ocean Element Profiles - 2
Which element could have a depth profile in the ocean that looks like this? A. It probably has a source from the atmosphere B. It is probably an essential nutrient for phytoplankton C. It probably has a source ...
ConcepTest: Ocean Element Profiles - 1
Which element could have a depth profile in the ocean that looks like this? A. Oxygen, an element produced during photosynthesis B. Barium, an element required in trace amounts for micro-organisms C. Nitrogen, a ...
