Why did people use seals?
Government officials marked their property so nobody could steal it. Their neighbors further east in India and west in Greece, from the Early Bronze Age, about 2100 BC, learned to use seals too. By the Qin Dynasty, about 200 BC, people were also using seals in China.

How can I make a seal?
You can make seals and seal things, just like people did in the Bronze Age. Seals can be made from anything hard enough to mark wet clay (or Play-Dough). Soap is a good choice and easy to carve. If you leave a bar of soap exposed to the air for a week or two it will get harder, but not too hard to carve with a butter knife.
Or you can use Sculpy clay; carve your seal with pencils, and then let it dry.
There are some excellent images of cylinder seals that 9th graders made here:
Be sure to design a seal which is different from anybody else’s!
Now seal something closed!
Take a box, like a shoebox, and put something in it. Put the lid on. Stick a gob of clay (or Play-Dough) over the join between the lid and the box, to stick the lid closed, and press your seal into it while the clay is still wet, then let it dry.
Or, just put a small object inside a gob of clay, then seal it by pressing your seal on the outside of the clay, and let it dry.
How writing was invented
Now mix yours up with other people’s. Can you tell which belongs to whom, by comparing the seals? What if you were a thief? How would you try to steal this stuff? What problems would you have?
