Stalactites And Stalagmites
High schoolers conduct a scientific investigation about the formation of stalactites and stalagmites. They conduct an experiment to reproduce them in the lab environment. Students make observations over a period of time in order to see...
Curated OER
Growing Crystals
Students are introduction to the cause and effect of a chemical reaction between water, mucilage glue, and magnesium sulfate as they form crystals.
Curated OER
Crystals
Fourth graders use mucilage glue and magnesium sulfate to make crystals. They mix the ingredients, place a drop on a glass slide and observe the forming crystals.
