QUESTION [6 upvotes]: Can someone suggest an idea for a school project in knot-theory for a 13 year old?
Thanks

REPLY [5 votes]: You may wish to take a look at the readable and well-illustrated Why Knot?.
Something to consider about knots is how 'basic' they are -- children will often learn to construct simple knots before learning arithmetic. This demonstrates an ability to manipulate (and distinguish between classes of) closed curves in three dimensions, and amounts to an intuitive theory of topology. We can use this as a staging ground to ask more interesting and difficult questions about knots and their classification.
