A Constructivist Version of the Snail & Elodea Lab
Students explain the importance of having a control when setting up an experiment.
Curated OER
Endothermic and Exothermic Lab
In this endothermic and exothermic reactions activity, students experiment with water and a salt of choice to determine if heat is absorbed or released in the reaction. Students take the temperature of their solution over a 2 minute time...
Curated OER
Weathering Lab
In this weathering worksheet, students use limestone chips and acidic solutions of pH 2 and 7 to determine if acidic solutions contribute to the weathering of rocks. Students determine which pH weathered the rocks the most.

Synthesis of an Insoluble Ionic Salt: A Stoichiometry Experiment
Challenge young scientists to design their own experimental procedures. They write the procedure for properly preparing two grams of a water-insoluble ionic salt. To finish, they perform the experiment and collect data to prove their...
Curated OER
Exploring Buoyancy
Students use materials found at a resource table to design simple devices that will house instruments to take water samples from a tub of water. They design 3 instruments, each varying in density so that one will float, one will hover...
