Curated OER
Properties of Fresh and Sea Water
Learners work with three stations to demonstrate the properties of water. They explore water's boiling point, freezing point, and its ability to store heat.
Curated OER
Properties of Fresh Water and Sea Water
Young scholars conduct experiments using water. In this properties of fresh and sea water lesson plan, students investigate boiling point, freezing point, and the water's retention of heat. Young scholars hypothesize, collect and record...

Water from the Well
How much water does it take to brush your teeth? How about to wash your clothes? Perform an experiment that measures water usage in everyday tasks and compares them to the days before indoor plumbing, specifically the California gold...
Curated OER
Water Cycle and Ecosystems
Students explore the water cycle. For this investigative lesson, students examine the water cycle process. They will record their observations and discuss marine and freshwater ecosystems.
Curated OER
Stacking Water
Students experiment with different salinities of water using straws and different colors of water. They collect and interpret data from the experiment.
Curated OER
Sea Water Freeze
Students observe how salinity affects the time it takes water to freeze. They participate in an experiment to determine that ice is essentially salt-free whether formed from fresh or salt water
Curated OER
Saltwater Science
Students conduct an experiment that shows them how salt water allows things to float. In this salt water lesson plan, students mix ingredients together to create salt water and observe how it makes the oceans dense. They then interpret...
