Blast Off!Transforming Potential Chemical Energy to Kinetic
EnergyGoals• 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.
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.
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 LaunchesData 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
