SUMMATIVE Grade 9

Egg Launch

• Challenge
  • design a method to launch and land an egg using a bottle rocket
  • keep the egg aloft as long as possible
  • keep the egg intact
• Restrictions and Requirements
  • only source of propulsion is the bottle rocket as demonstrated
  • no alterations to neck of bottle
  • no substitutions or additions to the water in the rocket
  • the egg must land
  • rocket shall be stable at time of launch
    • by either;
      • a suitable launch pad
      • or a stable self standing design of the rocket itself
    • to demonstrate stability the top of the rocket will be able to withstand a 5 N load in any horizontal direction without 50 mm of deflection; or be deflected in any horizontal direction by 50 mm and return to its original stable position.
  • launch will be disallowed if the rocket appears to be potentially unsafe for any reason including;
    • protruding sharp objects
    • potential aerodynamic instability
  • students may work in partners
• Process
  • Following the Design Method
    • Define the Problem(s)
      • "How can we..." or "We need to..."
      • Break the problem down into smaller problems
    • Rocket Design
    • Launchpad Design
    • Crash protection Solution
    • Conceptualize Possible solutions
      • design sketches
    • Choose and Test concepts
      • Template drawings
      • test plans
      • records and notes
    • Realize Chosen Solution
    • Review Design
    • problems solutions improvements
  • Materials
    • As mentioned the only source of propulsion may be a 2 L pop bottle
    • It is encouraged to use recycled or scrap materials which the students supply
    • there may be limited amount of material including foam and cardboard available in class.
      • You may only use class materials if specific prior approval is obtained from your instructor.
    • there will be low temperature glue guns available suitable to secure parts directly to the pop bottle.
  • Testing Option
  • One day (only) may be allocated for testing. In order to complete testing the CAD must be completed and web site on schedule.
  • A test plan must be created and approved by your instructor prior to testing.
  • The test plan must include;
  • The system or specific item (or variable) which you want to test.
  • A brief description of your test procedure.
  • A description of what you will measure in the test.
  • A list of materials and resources that you will need for the test.
  • A diagram if it increases the clarity of the test procedure.
  • No egg will be allowed for the test launch. A suitable replacement is allowed.
  • The Launch
  • All construction of the project must be done prior to launch day.
  • You will be given about 10 minutes to fill the bottles with water and install the egg on launch day. It is important that you are able to install the egg quickly within the timeframe.
  • Eggs will be numbered. To register an intact egg it must be retrieved and returned to the instructor on launch day.
  • All areas must be cleaned up after launch.

  What to Hand In

  • A design file - Click here for the format
    • problems definition
    • design sketches
  • CAD drawings of the Rocket will be completed
    • orthographic
    • pictorial 3-D
  • A 3D animation depicting your flight plan.
    • include the flight plan of your rocket and the path of the egg.
  • A website
    • technology explanations
    • rocket promotion
    • design improvement ideas
  • A rocket (launched)
    • stable launch platform or method
    • visual design
    • time egg in the air
  • Timeframe
    • The summative shall occur in the last 5 cycles of the year (16 classes). Be sure to catch up on absences and make sure your partner has access to information in case one of you is absent. "That was my partner's part of the project" will only be considered in the most extreme examples.
