Curated OER
Chemical Volcano
Students observe a demonstration performed by the teacher. They examine of a series of acid/base reactions and discover how various indicators work.
Curated OER
Lake Superior Ecology Unit
Sixth graders research Lake Superior and its ecosystem. Students investigate the lake's cycles of mixing and stratification and how these cycles affect the biology of the lake. This lesson plan contains five days of activities.
Curated OER
Yo-Yos, Tow-Yos and pH, Oh My!
Students explore how hydrothermal vents are formed and where they are located on the ocean floor. They study how scientists use CTDs to locate hydrothermal vents.
Curated OER
Gold Mine
Students view and discuss a demonstration of how gold is mined and panned. They design and create a tunnel that has reinforcements to withstand collapse.
Curated OER
Rate of Solution Demonstration
Students explore the factors that can increase the rate of dissolution for a solid. They complete a laboratory exploration in which they compare the dissolution rate of a whole sugar cube to that of a crushed sugar cube in a variety of...
Curated OER
Air Pollution Over Where?
Learners predict the movement of an air borne pollutant using their understanding of air currents. They determine which governments and/or communities should be contacted to be forewarned. They also explore the properties of their...

Science Buddies: What's the Point of Boiling?
You know that water can exist in three separate phases: solid (ice), liquid (water), and vapor (steam). To change from one phase to another, you simply add (or remove) heat. When water boils, what happens to molecules (for example sugar...
