Gases, Liquids And Solids
Students investigate how gases are different from solids and liquids and that they can evaporate and condense. They observe water boiling in a teapot and discuss what happens when the steam touches a cold window, complete an online Heat...
Curated OER
Warm and Cold Air
Students examine what happens to air when it is heated or cooled. They conduct an experiment using bottles and balloons, record and discuss their observations, and write a hypothesis.
Curated OER
What Is Energy? Short Demos
Students engage in three short, hands-on, in-class demos which expand students' understand of energy. First, using peanuts and heat, students see how the human body burns food to make energy. Then, they create paper snake mobiles to...
Curated OER
Atmospheric Processes - Radiation
Students investigate how different surfaces absorb heat, and how the physical characteristics of a surface have a powerful effect on the way a surface absorbs and releases heat from the sun.
