Tuesday, February 19th, Mr. Picazo's 5th grade class at Ray Darr worked on a lab over the properties of air.
Earth's atmosphere is composed of air.
Air is a mixture of gases, 78% nitrogen and 21% oxygen with traces of water vapor, carbon dioxide, argon, and various other components.
To explore this concept, the class worked on the Solar Bag Experiment.
A Solar Bag is a long plastic bag made from a very thin plastic and colored black to absorb solar energy. The heated air inside the bag provides buoyancy and causes the bag to float.
Go Mavs!
