The Chemistry of Ceramics
Students compare the characteristics of a fired porcelain sculpture to the clay used to create it. They discuss the physical and chemical changes that occur in the clay as it is heated and then create their own clay sculpture. This...
Curated OER
Heat Loss and Gain in Physical Changes and Chemical Reactions
Students compare and contrast exothermic and endothermic reactions. In this chemistry lesson, students perform experiments to determine whether heat was released or absorbed in a reaction. They share their observations in class.
Curated OER
Weathering
In this weathering worksheet, students investigate the effects of water and acid on limestone. They form a hypothesis for both and experiment to find the results.
