Soap, Slime, and Creative Chromatography
Do you think chromatography paper suffers from separation anxiety? Young chemists make soap, slime, silly putty, and experiment with chromatography in this lesson. The material includes clear instructions for each experiment along with...
Curated OER
A Comparison of Land and Water Temperature
Students examine NASA satellite observations of surface temperature and investigate the seasonal changes of land and water temperature.

Determining the Enthalpy Change of a Reaction
For this enthalpy of reactions worksheet, students use a known amount of copper (II) sulphate solution and an excess of zinc powder to calculate the enthalpy change of the reaction. Students measure the temperature change over the course...

California Crops
Students explore agriculture by researching the native food crops of California. Students define a list of agriculture vocabulary terms and analyze maps of California which explain which foods come from which area. Students write a...

Sliding and Stuttering
Ninth graders use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor. The spring scale allows them to measure the frictional force that exists between the moving cup and the surface it slides on....
