Monitoring Life in the Rocky Intertidal Ecosystem

Monitoring Life in the Rocky Intertidal Ecosystem Activity Source: NOAA National Marine Sanctuary Program and Farallones Marine Sanctuary Association, 2006. Adapted with permission. Background The five national marine sanctuaries along the West Coast monitor the health of the rocky intertidal ecosystem. One way of doing this is to collect data on the relative abundance of the organisms living in that ecosystem. Since this is such a big task, the national marine sanctuaries are training students in how to follow standardized protocols to help with the monitoring. [Read More]

Mystery Mollusc

Mystery Mollusc Activity Source: “Problem- Based Career Activity for the Mystery Mollusc NOAA Explore Poster” Written by Joyce E. Patterson Stark, NOAA Office of Education and Sustainable Development Problem-based learning is an inquiry technique that involves students working cooperatively in groups solving real-world problems. Students learn how to assess what they know, identify what they need to know, gather information and come to a conclusion. The teachers are the coaches or facilitators who give only guidance on how to approach the problem. [Read More]

Ocean Acidification

Ocean Acidification Activity Source: Adapted with permission by National Oceanic and Atmospheric Administration. The ocean is a “carbon sink,” which means that it removes CO2 (carbon dioxide) from the atmosphere. The ocean currently absorbs about one-third of the CO2 released by the burning of fossil fuels. However, beyond a certain level of atmospheric CO2, the ocean can no longer act as a carbon sink without it having a negative impact on marine life. [Read More]

Ocean Currents

Ocean Currents Activity Source: Teachervison; Excerpt from Ready-to-Use Earth Astronomical Science Activities for Grades 5-12 Objectives Students will map the patterns of the major ocean currents. Students will learn about the influences of wind, water temperature, landmasses, and water density on currents. Materials Tin pie plates Water Oregano or chili powder (or any herb that floats) Paper or plastic straws Food coloring 150 ml beakers Hot plate (if hot tap water is not available) Table salt Map of the world Reference materials Procedure Point out that ocean currents are driven by the wind and influenced by the landmasses that obstruct the flow of water as well as the density and temperature of the water.

Ocean Currents Change Our Earth

Ocean Currents Change Our Earth Activity Source: NASA. Adapted with permission. Ocean currents — the continuous, directed movement of ocean water — affect regional climates and alter the biological and chemical characteristics of seawater. Currents can flow for long distances both at and below the ocean’s surface. Wind drives surface currents, whereas density often drives deep ocean currents. Density, a physical property of matter, is mass per volume. Density is not simply weight — it depends on the volume of the sample (the amount of space the sample occupies). [Read More]

Rain and Soil

Rain and Soil Activity Source: Adapted with permission by Soil Science Society of America. When it rains, much of the water drains directly into the ground. But why? Soil is made up of four main components: minerals, organic matter, water, and air. Ideal percentages of each is shown in the figure, but in reality the percentages vary from location to location. Water moves through open spaces in soil known as “pores. [Read More]

Sea and Ice Salinity

Sea and Ice Salinity Activity Source: NASA Aquarius Mission and the National Snow and Ice Data Center, 2007. Activity adapted with permission from UCLA Marine Science Center’s OceanGLOBE. Background What is sea ice? It is simply frozen ocean water. Why is sea ice important? While it occurs mainly in polar regions, sea ice influences our global climate. Changing amounts of sea ice can affect ocean circulations, weather patterns, and temperatures around the world. [Read More]

Sea Level and the Terrapin

Sea Level and the Terrapin Activity Source: U.S. Environmental Protection Agency. Adapted with permission. The diamondback terrapin (Malaclemys terrapin) is the only North American turtle fully adapted to life in brackish water (mix of saltwater and freshwater). Its home is in coastal salt marshes of estuaries along the Atlantic and Gulf coasts of the United States. Although they can live 40 years or more, most turtles do not make it to their first birthday, because they are prey for foxes, otters, raccoons, skunks, and birds. [Read More]

Sky and Cloud Windows

Sky and Cloud Windows Activity Source: The Weather Channel. Adapted with permission. Is today sunny or overcast? Is there wind, rain, or snow? No matter where you live, weather shapes your life. What’s happening in the sky can determine how you dress, what you eat, where you spend your time, and when you work—or play. The science of the sky encompasses Earth and space science (from the solar system to the water cycle), physical science (from heat and energy to motion and forces), and science in personal and social perspectives (from the environment to global climate change).
