Albedo, Reflectivity, and Absorption
What is reflectivity, and what does it have to do with the Earth's climate? As reflectivity is measured by albedo, scientists can gather information on Earth's energy balances that relate to global warming or climate change. Budding...

Waves and Currents
Students are introduced to the forces that are responsible for generating waves in the ocean and how these forcesf differ from those that cause currents. They are able to explain how water molecules in a wave do not move in the direction...

Conductivity - Pass the Buoy and Pepper, Please
Buoys around our coastlines are equipped with sensory devices which monitor temperature, salinity, and water pressure. Emerging earth scientists examine some of this data and relate salinity to the electrical conductivity of the surface...

Fish and Zooplankton Through Remote Sensing
Ecology aces examine sea surface temperature maps and relate temperatures to concentration in fish and zooplankton populations. Take your class to a computer lab and provide experience with actual remote sensing data. Some of the links...
PHET
Planet Designer: Kelvin Climb
It's time to get those creative juices flowing! This second lesson in a series of five continues allowing pupils to design their own planets. It the same format as the first, but, this time, allows high schoolers to alter greenhouse...

Light Stick Chemistry
In groups of three with the lights off and the shades drawn, investigators place inactivated light sticks, in three beakers: one filled with ice water, another with lukewarm water, and the other with room temperature water. They wait...
NOAA
History's Thermometers
How is sea coral like a thermometer? Part three of a six-part series from NOAA describes how oceanographers can use coral growth to estimate water temperature over time. Life science pupils manipulate data to determine the age of corals...

Observation Milk Fat Lesson
Turn your class loose to experiment with the different fat content in skim milk, whole milk, half and half, and heavy cream. This is a visually vibrant experiment, as learners drip food coloring on the surface of the products and measure...
Georgia Aquarium
The Ocean's Nursery
Linear perspective, estuaries, and water ways converge in a science-inspired art project. The class uses what they've learned about eco-systems, estuaries, and the food chain to create scale models of a local marsh. While the...
