Blast Off!Transforming Potential Chemical Energy to Kinetic Energy Goals Objectives Students will be able to describe the transformation from potential chemical energy to kinetic energy from a model rocket launch and the chemical reaction between Alka-Seltzer and water. Students will be able to calculate the height of an object using geometry and trigonometric functions of triangles. Students will be able to explain how Newton’s third law of motion (action-reaction) dictates the motion of a rocket. • Students should learn about the transformation of potential (chemical) energy to kinetic energy (thermal, mechanical, light, etc) • Students should learn about the use of triangulation to calculate the height of objects; • Students should understand Newton’s third law of motion.
Pre-Day 1 • Review of Geometric/Trigonometric Functions • Sum of all angles in a triangle equal 180 • Sine, Cosine, Tangent functions
Blast Off! Day 1 • Station 1: Energy Transformation • Alka-Seltzer and Water combined into a file canister
Blast Off! Day 1 (cont) • Station 2: Triangulation • Simulated Rocket Flight – Calculate height using triangulation • Cover transit operation • Cover day 2 responsibilities
Blast Off! Day 1 (cont) • Station 3: Measurements • Used extra teacher to ensure students completed the worksheet.
Blast Off! Day 2 Model Rocket Launches Data Collection Very Successful – All data collected and no injuries or fires.
Blast Off! Day 3/4 • Data Analysis and Conclusions • Students followed step-by-step instructions on a worksheet to calculate kinetic energy • Worksheet took longer than expected. • Students finished calculations overnight • Day 4: Students graphed propellant vs KE • Wrap-up
Engineering Connection • Application • Rockets (Satellites, Astronauts), Vehicles • Career • Aerospace, Mechanical, Chemical Engineering • Societal Impact • Scientific Advances, GPS, Radio, Television, Weather Forecasting, Surveying, Military Uses (Secret Tasks), Transportation
