GI-NORMOUS GIRAFFES

Ponder on the development of life. Consider Darwin's comments about the origin of the Giraffe's long neck whilst having a go at constructing a giraffe from newsprint and masking tape!

What to do:

The challenge is to construct the tallest 'giraffe' possible, using only newspaper and sticking tape.

Suggested challenge rules:

  1. Time allowed is 30 minutes
  2. Teams of three people
  3. The giraffe must be 'free standing' (not attached to table top or propped against a wall)
  4. The giraffe must have an identifiable: head, neck, body, four legs
  5. The tallest giraffe wins! The height will be measured from the top of the head to the surface on which the giraffe is standing.
  6. ONLY the materials provided may be used. The newspaper may not be cut - entire sheets need to be used.
  7. The judges' decision in all matters is final!

Remember:

Building Hints and Tips:

  1. Good planning, design and TEAMWORK are essential to building a successful giraffe!
  2. Newspaper can be a very versatile construction material. Rolling the paper TIGHTLY is important to strength.
  3. A stable 'free standing body' is important to achieve, make this your first priority before adding head and neck. Think about what makes a 'strong shape' (triangles are good!) How do you stop the legs from 'splaying'?
  4. Height can be achieved both by extending the legs AND by creating a very long neck.
  5. A long neck adds considerable weight to the front of the animal. How are you going to prevent toppling? Making the front and back legs different lengths may assist with stability. Would it help to slant the neck backwards towards the tail?
  6. How does nature do it? Look at photographs of real giraffes - they have enormously strong neck and shoulder muscles.
  • The giraffe is the world's tallest animal. Males stand 4-5 metres high
  • Giraffes rarely lay down, they sleep standing up and sleep for only 1-12 minutes at a time!
  • Giraffes spend 16-20 hours a day feeding
  • Giraffes have the highest known blood pressure of any mammal
  • Giraffes have elastic blood vessels in their neck so that they can drink water without fainting!
  • Each giraffe has a unique coat pattern
  • Despite its extreme length, the giraffe neck is too short to reach the ground, as a result the giraffe has to awkwardly splay its front legs or kneel down to drink
  • Like camels, giraffes can go for long periods without drinking water - they get most of their water from the leaves they eat
  • Giraffes can reach speeds of up to 35 mph
