Curated OER
Vapor Pressure
This extensive collection of slides begins with diagrams of molecules undergoing evaporation, progresses through methods of measuring pressure, demonstrates how to perform pressure calculations, and then explores the temperature-pressure...
Curated OER
Temperature Changes Everything
Middle school chemists visit interactive websites in order to discover what happens to molecular motion when heat is added to matter. They conduct an experiment that demonstrates the expansion of matter with the addition of heat. A lab...
Curated OER
The Water Cycle and Global Warming
Students study the flow of water in the environment. In this water cycle lesson students evaluate the consequences of changes in the water cycle using data.
Curated OER
Freezing and Boiling Point
In this freezing and boiling point graph worksheet, students use the graph illustrated to respond to several questions that follow. They identify what is the freezing, boiling, and melting point of the substance in the graph. Students...
Curated OER
Introduce Solids
Young scholars identify and interpret a variety of solid materials - cloth, wood, metal, plastic, paper, and rubber. After a period of free exploration, they then describe the properties of the objects and develop vocabulary in order to...
Curated OER
Condensation
Students explain how water changes from vapor to liquid with a change in temperature by engaging in this experiment. They use a worksheet imbedded in this lesson to guide their inquiry.
