Grade 4: Rocket Racers!

Fourth grade returned to their study of Aerodynamics today and continued working on rocket racers.  We designed cars completely fabricated from Styrofoam and straws of various sizes.  Our rocket fuel is air coming out of a balloon.  We started our first distance trials today!  Our cars had some good distance, (we kept a data chart to record) although steering and balloon/straw placement was an issue.  Following the engineering design process we will modify our designs and retest for our 2nd and 3rd trials.
