The Greenhouse Effect: The Role of CO2
Though this is meant to be second in a two-part lesson, the two are not dependent on each other. Pupils play the roles of visible light rays, light or dark surfaces, and carbon dioxide molecules. They interact and react according to...
Curated OER
Big Extinction
Students discuss evidence of a pre-dinosaur era meteoric collision, and its impact on living creatures. They build buckyball molecule models out of marshmallows, toothpicks, and soccer balls.
Curated OER
Density
Students, in groups, design a procedure to calculate the mass of gas molecules in the classroom by measuring the volume of the classroom and researching the density of air. They apply changes in air density with altitude and effects on a...
Curated OER
Rising Water!
Students observe water change from a liquid to a gas state when heated and then return to its liquid stage when cooled. They learn that gas molecules move faster than liquid molecules. They discover physical properties that describe how...
