This experiment has student teams comparing a sample of room air with one of the greenhouse gases - carbon dioxide, nitrous oxide, or methane - and observing the relative effectiveness of the gases in trapping infrared (IR) radiation. The activity... (View More)

This is a hands-on lab activity about seawater density. After developing a hypothesis, learners will conduct a simple investigation of density. They will discuss changes in density observed and describe how salt affects the density of water.... (View More)

In this laboratory activity, students investigate chromophoric dissolved organic matter (CDOM) through gradual dilution of black, green and chamomile tea. Through this activity, students discover how CDOM can dominate the absorption of sunlight, how... (View More)

This is a hands-on lab activity about the composition of salt. Learners will explain the general relationship between an element's Periodic Table Group Number and its tendency to gain or lose electron(s), and explain the difference between molecular... (View More)

In this laboratory activity, students experiment with becomes CO² concentrations in water as a prelude to investigating the marine carbon cycle. The activity includes a worksheet and assessment questions. Tap water, ocean water (real or simulated),... (View More)

In this lab activity, students examine phytoplankton and picophytoplankton under a microscope and learn how to use a stage micrometer to measure microscopic specimens. Resources needed include a microscope, slides, coverslips, a stage micrometer,... (View More)

In this lab-based activity, students learn how to use scientific instruments used to take hydrological data. Students will rotate among measurement stations for each of the hydrology protocols that will be done by the class. They will practice using... (View More)

In this laboratory activity, learners explore the difference between heat and temperature, and explore the rate of heat transfer from one substance to another as it depends on the density of the substances being investigated. The activity can be... (View More)
