Curated OER
Cement and Concrete Engineering
Students explain the components of the engineering design process. In groups, they identify the materials that make concrete and practice curing cement using the various methods available. They develop a graph showing the amount of...
Curated OER
Hot Rocks
Students demonstrate that setting of plaster and cement is a change, which involves a release of heat energy, use data collected experimentally to construct comparison graphs and analyze the graphs to make predictions about future...
Curated OER
Exothermic Rehydration of Gypsum
Learners observe exothermic reactions in the lab using plaster. In this chemistry lesson, students collect data from their experimental set up every five minutes. They explain the different stages in the hardening of plaster.
