Congratulations!

You and three of your classmates have been chosen to join a special expedition that will travel back in time thousands of years. You will find a very different world from the one you are used to!

There will be no hamburgers or coke, no cars or planes, no flushing toilets or toilet paper, and no TV or computers. It might be a very good idea to pack a few things to take with you, if you think you couldn't do without them - they would have to be small and light, though, and not things that would frighten the people around you.

You will need to find out what sort of clothes to take with you, so that you fit in with the locals, and how to behave, so you don't get in trouble. You are there for three weeks, so how will you get around, and sleep, and eat? Don't forget that you will probably have to pay for things, too!
