Lesson Nine: Building and Launching Water Rockets

  • Elementary school (grades K/1–2/3/4/5/6)- from 5 to 10 years old
  • Intermediate school (3/4–5/6) from 8 to 12 years old
  • Middle school / junior high school (grades 5/6/7–8/9) from 11 to 15 years old
  • High school / senior high school (grades 9/10–12) from 15 to 17/18 years old

Natural Sciences: material properties.

Art: Designing, decorating the rocket

Mathematics: Measuring and mathematics

2 hours

Shooting a coca cola bottle, transferred into a rocket, into the sky is conducted simultaneously with lessons on the universe and physics, students learn all about space, pressure and physics. As a practical activity, they make a water rocket. Video of the launcher will be available in resources. Water is necessary to make the rocket go higher.

Objectives:

  • Understand basic principles of physics, including pressure and forces.
  • Learn about space and rocket science.
  • Apply creativity in designing and decorating rockets.
  • Develop teamwork and collaboration skills

Dimensions

  1. Self-Confidence in Science and Technology. Students build their confidence as they successfully create rocket and make it fly.
  2. Technology Can Be Learned. The activity of taking a simple every day object and applying physics, step-by-step process, students learn about space pressure and physics.
  3. Practical Orientation. This activity focuses on hands-on learning by changing everyday material into something els using physics.

Types

  • Creative Makers: This activity involves physically building and experimenting with objects, which resonates strongly with their preference for creating tangible objects.
  • Doer: Assembling the rocket, making it by hand
  • Explorers: Benefit from the guidance of building a rocket, helping them gain confidence while exploring elements of physics.

The teacher(s) for this lesson need to be able to teach physics principles. Also, teach basic safety and construction with cardboard materials.

Preparation: Launching platform, pump

  • Empty Coca-Cola bottles (one per group)
  • Cardboard
  • Scissors
  • Tape and glue.
  • Water
  • Bicycle pump or air compressor.
  • Launch pad
  • Paints, markers, and other decorating materials

Safety rules & tips

Don’t push the pressure above 8 bar bottles can explode!

While launching beware of the direction of the rocket flying to (buildings, cars, people) best to do on a sports field!

Building and Launching Water Rockets The students in class 2 will build and launch water rockets within 2 hours. The rockets are made from Coca-Cola bottles and cardboard. Students work in groups of 2 or 3. Two rockets will be launched simultaneously each turn, allowing the students to compete against each other.

Introduction (20 min)

  • Welcome and Overview (5 minutes)
  • Brief introduction to the project and its objectives.
  • Explain the scientific principles behind the water rockets: pressure, force, and how rockets launch.

Step-by-step development

Lesson on Space and Physics (15 minutes)

  • Discuss the basics of space and the universe.
  • Introduce the concept of pressure and how it propels rockets.
  • Use visual aids and videos to enhance understanding.

Group Formation and Material Distribution (10 minutes)

  • Divide students into groups of 2 or 3.
  • Distribute materials to each group.

Building the Water Rockets (30 minutes)

  • Design and Planning (5 minutes): Each group sketches their rocket design and plans decoration.
  • Cutting and Assembling (15 minutes):
  • Cut cardboard fins and nose cones.
  • Attach fins and nose cone to the Coca-Cola bottle using tape and glue.
  • Allow students to decorate their rockets using paints, markers, and other materials (10 minutes)

Preparing for Launch (10 minutes)

  • Demonstrate how to fill the bottle with water (about one-third full).
  • Show how to attach the bottle to the launch pad.
  • Ensure safety precautions are understood.

Launch Procedures (40 minutes)

  • Launch two rockets simultaneously for each turn.
  • Allow each group to have a turn.
  • Measure and record the height and speed of each launch.
  • Encourage students to cheer for their classmates and discuss the results.

Discussion, conclusion and Reflection (10 minutes)

  • Discuss what happened during the launches.
  • Ask students what they learned about pressure, forces, and teamwork.
  • Reflect on what could be improved for future launches.

Cleanup and Organizing (10 minutes)

  • Ensure all materials are collected and the area is cleaned up.
  • Store reusable materials for future projects.

Related and supporting activities/modules

Assessment:
