Unsharpened pencil at each table
Say: will someone at each table pick up the shiny yellow thing?
What is it called? What is it for?
Is that a good pencil or a bad pencil? How do you decide if it's good or bad?
(Hold up the variety of pencils)
So it doesn't matter if it's long or short, pretty or plain, old or new, right? A pencil is good if it writes, bad if it doesn't?
Can I write with it now?
What does sharpened mean?
Poke a leader with it.
Hey look, I can use it as a weapon. Is that a good use for it? Why not?
Could you make a pencil? What raw materials would you need?
So now I've got a big pile of stuff: wood, graphite, metal, rubber, yellow paint, black ink, a stamp for the label. How do I go from that pile to this pencil? What process would you need to make this pencil?
