If you're giving a birthday party, there's so much you have to think about: who to invite, what to give them, what presents to ask for, where the party will be (at the swimming pool or at home), when .. ?? and so on. Having all kinds of questions ready in your head will help you. Then you'll remember the things you've learned more easily.
Let's suppose you want to know more about American Indians, and to remember what you learn about them. You've looked up stuff on the internet. Or you've borrowed a book about Indians from the library. Get these questions ready first (5xW+H):
	Who is it about? (Indians)
	What do I know already? (the earth, sun, moon, plants and animals are important for them)
	Where do they live? (in North America)
	What do they look like? (headdress)
	When were they discovered?
	What more do I want to know about them? (how they live now, why they're called Indians, and how many of them are still living?)
	Why do I want to know? (because I want to give a talk about Indians)
	How long do I want to talk about them?
Need to learn something? First get your questions ready in your head. Write the answers down.
