1
What is Engineering?

• Problem solving
• Design
• Innovation and Creativity
• Application of math and science
• Teamwork and Leadership
• Communication
• Professional

2
What do Engineers do?

• Work in industry, government or consulting
• Develop surgical instruments
• Design municipal infrastructure (water
  distribution lines, water treatment)
• Remediate a contaminated site
• Design a robotic systems for a production line in
  a factory

3
Engineer or Scientist Whats the difference?

• Science understand concepts, learn about theory
  and principles, have expertise
• Engineering applies principles of math and
  science to solve real-life problems
• Engineers and scientists often work together as
  part of a team
• Engineering is a profession P.Eng

The Mission

• Design, build and test a device to transport a
  marble from less than a foot off the floor into a
  column of water
• Slow the descent of the marble to the greatest
  extent possible
• Maximum time completely under water, not touching
  the bottom

11
The Rules

• You may attach a device to the marble to suspend
  it in the water column
• You may not change the marble
• Human energy can only supply potential energy to
  the launch mechanism
• If you add something to the water, it must be
  added with the marble mechansim
• No explosives can be used

12
More Rules

• Made entirely by recycled materials
• Constructed by the group
• Total equivalent cost less than 50
• Safe for a nine year old to use
• No animals may be used/harmed in the design

13
The column

• Column 3 feet high
• Water filled to within 2 inches of the top
• A shallow sheet metal funnel will be attached to
  provide a greater entry radius (approx 3-4 feet)
• Launch mechanism can touch the metal funnel but
  not the column or the water

14
What do you need?
15
The Criteria

• How long does the marble to descend to the bottom
  of the water column (longer is better) to a max
  of 5 min.
• How expensive (cheaper is better)
• Aesthetic appeal
• Simplicity of design
• Unique, innovative design

16
Brainstorming the first step

• No idea is a stupid or silly idea
• Wild and crazy is good suggest ideas without
  thinking too hard
• One person record all of the ideas
• No one is allowed to prove any ideas wont work

18
Solution 1 Elastic launcher

• Launching arm on an elastic band, potential
  energy by drawing back the arm launches the
  marble
• Added prop to elevate the launcher
• Adjustable to change the range of the launcher
  and improve accuracy

19
Solution 1 Cork floater

• Marble attached to cork buoyant forces
  counteract the weight of the marble
• Flat piece of cork acts to provide drag in the
  water

21
Solution 2 Weight pulley on a ramp

• Weight (pop bottle filled with nails) attached by
  string to ½ popcan holding the marble flotation
  device over a pulley (old inline skate wheels)
• As weight falls by potential energy, the can with
  the marble leaves the floor and rises to the
  column and tips the marble flotation device into
  the column

22
Solution 2 Oil capsule

• Spherical capsule filled with canola oil (lighter
  than water)
• Fishing weights and paperclips to balance weight

23

24
Solution 3 Counter-weight lift device

• Elevator type lift wooden structure with a
  angled platform
• Free weights attached by string to the platform
• Once released from the top of the structure, the
  weights fall, and the platform rises, releasing
  the flotation device into the column

25
Solution 3 Water balloon

• Large balloon filled with water, diameter
  slightly less than the diameter of the column
• Marble inside
• Attached to a PVC pipe capsule containing
  alka-seltzer
• When balloon is released, water leaks into
  capsule through a drilled hole
• Reaction with alka-seltzer released gas,
  increases the balloon diameter, balloon gets
  stuck in column
