Curated OER
Rock Candy Crystals
Learners discover how rocks are created. In this rock formation lesson plan, students investigate saturation, evaporation, and phase changes in geology. Learners create rock candy from skewers, string, boiling water and sugar.
Curated OER
Adventures With Super-Absorbers and Substance Solubility
Students understand the concepts of absorption, swellability and solubility and recognize that science is all around us in our everyday lives and is fun to explore.
Curated OER
Solubility
Fifth graders determine the difference between a soluble and an insoluble solution and how to increase solubility. They make a saturated solution using solvents at different temperatures.
Curated OER
Disposable Diaper Comparison and Mystery Powder Identification
Learners investigate which diaper is the most absorbent. In this chemistry lesson, students calculate how much water is absorbed by diapers. They identify an unknown powder based on physical and chemical properties.
Curated OER
Ice Energy
Students observe the chemical reaction that occurs when salt is put on ice, and use the energy that is released to make ice cream.
Curated OER
Ice Energy
Students investigate how salt affects the state of ice. In this ice cream making lesson plan, students change the freezing temperature by adding salt and observing the results. Students use experimentation and comparison to see how...
Curated OER
Boy, Is That Buoyant!
Fourth graders see that salt increases the density of water and creates a condition wherein objects are more buoyant than would be expected under normal conditions. They describe the relationship between heat energy, evaporation and...
