Model Rocket Building Notes

Chapter 1: Introduction to Model Rocketry

• Overview: Today's class focuses on building model rockets, aiming for them to follow a parabolic trajectory.

• Goals for the Day:

  • Build rockets using available materials in about 20-30 minutes.

  • Ensure that all students have Logger Pro installed on their computers for data collection.

• Materials Needed:

  • Construction paper, tubes, glue guns, tape, and Logger Pro software.

• Planning for Launch:

  • Next class will involve launching the rockets and collecting data via video recordings.

  • Students may use their phones to capture the launch.

Chapter 2: Launching the Rocket

• Group Work:

  • Students will work in groups of 2-3 for the project.

• Rocket Launcher Description:

  • The rocket will use an air-powered launcher composed of PVC and a valve.

  • Rockets must slide snugly onto the launch tube.

  • Optimal launch pressure is around 30 PSI.

• Rocket Construction:

  • Rockets can be made from rolled construction paper around a tube.

  • The appearance of the rocket is less important than its functional design.

Chapter 3: Fins and Cone

• Design Recommendations:

  • The cone should be airtight to prevent air leaks.

  • Recommended to use white card paper for fins as it provides better rigidity.

• Fin and Nose Cone Design:

  • Simpler fin designs are preferred to ensure stable flight.

  • A weighted nose cone is advisable to maintain stability during flight.

  • The ideal balance point of the rocket should be between the fins and the nose cone.

Chapter 4: Height of Rocket

• Launching Mechanics:

  • Successful rockets will follow a parabolic trajectory.

  • Students can choose the perspective of their video recording to capture the launch effectively (front or side view).

• Data Recording with Logger Pro:

  • Logger Pro will track the height and x/y positions of the rocket throughout its flight.

  • Students can analyze height versus time or distance versus time.

Chapter 5: Point of Rocket Analysis

• Data Analysis Requirements:

  • Students must organize data into presentations (Google Slides or typed documents).

  • Must develop models in vertex form and standard form using data collected.

  • Perform quadratic regression analysis using Desmos and calculate the percentage error of landing spots.

• Math Problems to Solve:

  • Find out when the rocket is at a height of three meters, and the duration above that height.

• Conclusion Requirements:

  • Discuss real-life applications, assumptions, and limitations of the project.

  • Suggest possible variations (e.g., launch angle changes).

Chapter 6: Collaborative Efforts and Final Thoughts

• Group Collaboration:

  • Grades will reflect collective efforts within groups, promoting teamwork.

  • Each group will submit one rocket design for simplicity and efficiency.

• Preparation for Next Class:

  • Ensure all students are ready for the launch.

  • Collect glue guns immediately after use to prevent damages.

  • Address any final questions before construction begins.
