Flower challenge

Reds ... yellows ... greens ... we need to make the room more colourful! Can you make a model of a flower for us, the bigger the better?

Levels of difficulty:
Level 1 - Make a simple flower
Level 2 - As level 1, plus a pot that it grows in
Level 3 - As level 2, plus a string to pull to make the flower grow!

Equipment: K'NEX set, plus 1m length of string for level 3.

Approach: How many different sorts of flower do you know? What colours are they? What shape are they? Can you make a model of one of them from K’NEX?

For level 2, can you make a pot for the flower to grow in? How will you fasten your flower into the pot?

For level 3, can you make the stalk of your flower slide up and down in the pot? Do you think you could tie a piece of string to it, so that when you pull the string the flower grows?
