Carolina STEM Challenge®: Chemical Reaction Rockets Kit
Students apply their knowledge of chemical reactions to solve the engineering problem, “What is the best way to modify a chemical reaction to maximize the altitude of a rocket?” Teams complete a prototype activity during which they observe the effects of chemical changes in a chemical system. Next, they create a simple rocket to explore the energy transformations that propel the rocket into the air. During the design challenge, teams brainstorm ways to modify the reaction and the design of the rocket tube to maximize altitude. The activity concludes with a classroom competition of the engineered rockets.
Time Requirement
Total, 285 minutes. Teacher prep, 30 minutes. Prototyping and the design challenge, 150 minutes. Design challenge presentation and assessment, 105 minutes.
Digital Resources
