Curated OER
Science: Fossil of a Carbonized Plant
Students classify leaves by shape and margins and use them to create models of plant fossils. By using paper over a leaf, they simulate fossilization of organisms onto sedimentary rocks. Following instructions on worksheets, students...
Curated OER
Science: Making Trace Fossils
Young scholars explore types of fossils and discover how sediment affects fossil preservation. They focus their study on trace fossils and create their own using sediment, water, and a small organism such as a snail or lizard. Students...

Energy Resources: Where Are They and How Do We Get Them?
Future energy engineers visit several stations, each one dedicated to a different alternative source of energy. They describe how solar energy is converted into other forms of energy, the patterns of distribution of energy resources in...
Curated OER
Carbon Dioxide - Sources and Sinks
Where does all of the carbon dioxide come from that is supposedly leading to climate change? Earth science pupils test animal, plant, and fossil fuels as sources in this investigation. Using an indicator, BTB, they are able to detect the...
Curated OER
Environmental Studies: The Power of Wind
Investigate the prospect of wind as a renewable resource. Second and third graders make a pinwheel, answer critical thinking questions, and then attempt to use wind power to wind string. I would be more apt to use this lesson in a 1st or...
Curated OER
Fuel Cells
Learners examine how fuel cells and combustion engines work. Using the internet, they research the positives and negatives of the various energy sources. In groups, they complete an experiment with a working fuel cell model and take a...
Curated OER
Primary Energy Sources Pros and Cons
Students explore the different types of renewable and nonrenewable energy sources. In this earth science instructional activity, students discuss the pros and cons of each type. They conduct a variety of experiments on renewable energy.
Curated OER
Rocks, Minerals, and Erosion
Students identify and describe rocks that contain records of the earth's history and explain how they were formed. They formulate questions about and identify needs and problems related to objects and events in the environment, and...
Curated OER
Cell Structure and Function
Students discuss scientific advances brought about by the Mars Surveyor Space Program which impact on daily life, identify laboratory apparatus like microscopes, slides and coverslips, and use the microscopes to view cells and organisms.
Curated OER
Acid Rain - Go Away
Young scholars set up an experiment and make observations of the effect of acid rain.
