Curated OER
Water Use and Conservation
Students discuss the different types of water found on Earth. They discover why not all water is used for drinking and calculate how much water they use. They create their own water conservation plan.
Curated OER
Settling Rates of Different Size Particles
High schoolers discover how and why the settling rate of particles differs with the size of the particles. Using different soil samples, they calculate the amount of time it takes for a sample to settle in water for up to forty minutes....
Curated OER
Determine Soil Particle Size
Students examine various soil samples in groups. Using the samples, they identify the characteristics of them and calculate percolation and infiltration rates. They use this information to discover why some species can survive in one...

Activity 4: Alvin Dive, A Mysterious Encounter and Change Over Time
Students receive copies of the Time Series Observations to use for note-taking. They work in small groups to discuss what they see when the outside lights of Alvin are turned on, and off, where the bacteria may have come from. They view...

Making a Food Web and Learning About Ecosystems
Third graders examine the difference between a food web and food chain. They also examine the importance of the sun in a food web and food chain. Students understand what happens when you remove parts of the chain.
Curated OER
Science: What Happens to Create the Lode?
High schoolers understand how mineral deposits are formed and why they are not evenly dispersed. They create and describe three different precipitates from four solutions simulating mineral ore deposit formation in sedimentary rock.

Getting to Work and Making Money
Learners explain how geography and climate play a role in the professions that are unique to their city. They explain how geography and climate influence the forms of transportation in their city.
Curated OER
Natural Hazards
Students evaluate the hazards of naturally occurring events. After watching a video concerning safety hazards, students work in groups to discuss the safety issues involved in taking a trip to a mountainous region. Recommendations are...
Curated OER
Annotating Change in Satellite Images
Young scholars compare a series of satellite images taken 3-4 years apart to investigate the effects of human land use. They annotate the images using ImageJ software and use the annotated images to explain their findings.
Curated OER
Watershed Analysis
Students conduct a regional watershed analysis of an area of their choosing. Using on-line data and their personal knowledge of the area, they determine the annual hydrologic budget and teach the class about "their" watershed.
Curated OER
and and Ocean Views of Earth by Remote Sensing
Students explain how satellites help scientists to see more than with the unaided eye and how Landsat technology works. Students identify vegetation and fire sites in the rainforest and detect erosion along rivers. They are able to use...
Curated OER
Excavating the Past
Students discover how palaeontologists conduct a dig for fossils and how they interpret the age of the fossils. In small groups, they prepare a "dig site" consisting of bones, rocks and soil layered in a cardboard box. They switch boxes...
