What's a CTD?
Why are the properties of the water important when exploring the ocean? Young scientists discover the tools and technology used in deep sea exploration in the fourth installment in a five-part series. Groups work together to...
Curated OER
Ice Energy
Young scholars explore how chemicals change water. In this chemical change instructional activity, students participate in an experiment to observe how salt effects ice and how ice cream freezes.
Curated OER
Salt Water Wedge
Students 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 the...
Curated OER
We All Scream for Ice Cream
Students make ice cream while experimenting with the freezing point of water. They experiment with different amounts of salt.
Curated OER
Frozen Solids
Pupils investigate various properties of ice including melting points and the effect of pressure on ice. They demonstrate how increased pressure lowers the melting point of ice and perform a simple experiment proving that water is more...
Curated OER
Ice Cream
Students explore the concept of the colligative property. Through experimentation, students lower the freezing point of a liquid in order to create a solid by using household ingredients to create ice cream.
Curated OER
Osmosis and Dialysis
How do you engage pupils in a discussion about osmosis without leaving them overwhelmed? By providing them with the tools to perform an exciting experiment, and they will see osmosis in action! Young chemists and biologists use...
