Using Models to Understand Photosynthesis
Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...
Curated OER
Law of Conservation of Mass
Students work in small groups. They grab a handful of ice, and place the ice in an empty beaker of ice using a triple beam balance. Students heat up the beaker of ice over a hot plat until the ice has changed into water. They measure...
Curated OER
The Chemistry of Killer Coal
Students research chemical components of coal, as well as environmental health impacts of mining and burning coal. They discuss conservation of mass as it relates to combustion of organic compounds.

Swinging Pendulum
Learners engage in an activity which demonstrates how potential energy (PE) can be converted to kinetic energy (KE) and back again. Given a pendulum height, students calculate and predict how fast the pendulum will swing by understanding...
Purdue University
Design of an Earthen Dam for a Lafayette Neighborhood
How do dams support bodies of water? Scholars engage in a hands-on STEM activity where they design, build, and test dams to learn about bodies of water and how humans use natural resources. They learn how criteria and constraints affect...
