|Houston, we have lift off!|

What was a small step for man became one giant leap for third graders Thursday, Nov. 18. Duncan Brandt, freshman at the University of Colorado at Boulder, recently launched a hands-on experiment at Holyoke Elementary School, teaching the students all about the science of shooting rockets. After a series of lessons, test runs and lots of trial and error, third graders understood concepts like pressure, chemical reactions, aerodynamics and center of mass.
Third graders in the build group focused on the right balance of canister size and a vinegar/baking soda mixture that would get their rocket off the ground. The design group then created an outer shell for their rockets, remembering the weight, shape and size would all affect their rocket launch. It was exciting for students to see their hard work pay off when two of the five teams launched their rockets about 30 feet into “space.”
Last week’s activity was part of Brandt’s NASA outreach in his independent study this semester. Brandt serves as the lead of the GPS project ALL-STAR with CU’s Space Grant, a nationally funded program for student projects with NASA.
