Students investigate the effects of acid and bases on dyes made with plant materials.  In this chromatography lesson students predict color outcomes and complete a lab activity on color combinations.

Students explore the different phases of a crystal.  In this mineral lesson students grow their own sugar crystals using a sugar recipe. 

Students compare various brands of floor polishes and test their durability and appearance.  In this floor polish lesson students test different polishes and check performance. 

Students identify various kinds of paints by using the scientific method.  In this solvents lesson students collect data and identify paint samples while working in teams.

Students examine water and what causes it to become hard.  In this water lesson plan students use the soap test and determine the mineral content and hardness of a sample of water.

Students examine the different propereties of ice, such as freezing temperature.  In this scientific lesson students complete several activities using ice, like making ice cream.

Students study the concepts of polymerization and the function of crosslinkage.  In this polymer lesson students complete a lab activity and write down their observations. 

Students explore what chemical indicators are and use pH paper to determine if something is alkaline or basic.  In this pH lesson students manufacture their own soap.
