Creating a Freshwater Ecosystem
Pupils correctly identify some fishes of Texas and parts of their ecosystem.
Curated OER
Salt Water Wedge
Young scholars conduct an experiment to observe the properties of both salt and freshwater. They explain why freshwater will stay at the surface while salt water will travel up a river bottom because of density. Students also research...
Curated OER
Earth Water Distribution and Water Consumption
Students explore the need for conserving fresh water and understand that it is a limited supply. In this water consumption instructional activity students participate in an activity and answer questions.
Curated OER
Floating Pencil
Students discover how salt water makes a pencil float better than freshwater by measuring and comparing the lengths of the portion of the pencil that floats above the water surface. They then determine if an unknown water sample is...
Curated OER
Pond and Pond Organisms
Students explore pond ecosystems. In this pond organism activity, students will use pond water and a plastic bad in order to locate and identify freshwater organisms. The activity is designed for younger grades, but...

Aerobic and Anaerobic Microbe Analysis in a Subarctic Setting
Students investigate the relationships between protozoa, algae and monera in freshwater, shoreline soil, and reindeer rumen. They publish reports of their findings.
Curated OER
Water Sources in Cape Verde and West Africa
Learners analyze the importance of a fresh water supply in Cape Verde, researching five methods of obtaining and conserving water there. Students create and present displays demonstrating their understanding of the methods of water...
Curated OER
The Weight of Water
Students examine how salt water is more dense than fresh water. They discuss how manatees need to float and sink, conduct a sink or float experiment, and conduct an experiment with eggs and salt and fresh water.
Curated OER
The Captain And Lake Wilmar
Tenth graders examine the ecosystem of Lake Wilmar through three coordinated performance tasks. They first investigate the effects of pH on freshwater animals by comparing the zooplankton counts from three different areas. They then...
