Today's class started out with a discussion on air and its properties. The students discovered that because air is not empty space, it has properties that allow things to fly as long as those things have a certain shape. That shape is called an airfoil and is what helps an airplane fly -- more commonly known as the wing. Students learned about how different factors of an airfoil will change the amount of lift the airfoil produces. Students then built their own air foils. Then they used a wind tunnel to find the air speed over the wing.
After the break the students flew their mini airfoils in the wind tunnel. Then they used an airfoil simulation on the computer to change the different factors and see if a plane weighing 140,000 pounds still flew. Through this exciting class, they discovered how airplanes stay airborne!!
