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]

Monitoring Sustainability: Land Cover Data Activity Source: Earth Science Information Partners, Earth Observations for the Sustainable Development Goals Background Almost every aspect of life — ​our homes, food and water sources, and outdoor activities — ​is connected to the land on which we live.. Landsat satellites collect images of Earth’s surface but cannot zoom in enough to monitor small-scale changes. The Global Learning and Observations to Benefit the Environment (GLOBE) program has created an app so you can help fill in the gaps in the global dataset. [Read More]

Mud Fossils Activity Source: USGS Learning Web Lesson Plans. Background At the close of the 18th century, the haze of fantasy and mysticism that tended to obscure the true nature of the Earth was being swept away. Careful studies by scientists showed that rocks had diverse origins. Some rock layers, containing clearly identifiable fossil remains of fish and other forms of aquatic animal and plant life, originally formed in the ocean. [Read More]

My Mineral Activity Source: The Mineralogical Society of America Background Minerals are the naturally occurring solid materials that make up rocks and sands and are found in soil. You have probably heard of minerals such as diamond, halite (table salt), graphite, garnet, and quartz, but there are many others. New minerals are being discovered all the time. There are 6,017 minerals as of this writing, and you can learn about them online in the Handbook of Mineralogy, Mineralogy4Kids, and on the Mindat website. [Read More]

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]

Natural Gas Formation Activity Source: Adapted by AAPG from the American Geosciences Institute. Adapted with permission. Natural gas, which is mostly methane, is an energy resource used for generating electricity and heating, powering transportation, and manufacturing products. Right now, one-quarter of the world’s energy comes from natural gas. Natural gas formation, one of the processes occurring on our ever-changing Earth, takes a very long time. Natural gas is formed from marine organisms that die, sink to the bottom of the ocean, and get covered with sediments. [Read More]

Nitrogen Connection Activity Source: Adapted with permission by Soil Science Society of America. All biological organisms require certain nutrients to live. Plants require carbon, hydrogen, and oxygen from air and water, as well as nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, manganese, copper, zinc, nickel, chloride, boron, and molybdenum from soil. Animals require a few others. Conversions and transformations of nutrients in the environment result from chemical reactions, biological activity, or both. [Read More]

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 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.
