Sleep and wake are verbs (although we usually use "wake up" for when you stop sleeping, and "go to sleep" for the moment when you begin sleeping):

My kids go to sleep at 10 PM.

I slept during the 6-hour flight.

I wake up at 7 AM and I have to be at work by 8.

Yesterday I woke up late because my alarm didn't go off.

You can also use wake up for the action of making someone else stop sleeping:

Don't talk so loudly! You'll wake up the baby!

Your sister is taking a short nap. Can you wake her up in about 20 minutes? Awake and asleep are adjectives. Use them with the verb to be:

He's awake. = He isn't sleeping.

He's asleep. = He is sleeping.

It's common to use the expressions stay awake / stay up (to continue awake) and fall asleep (to begin sleeping):

On New Year's Eve, my children stay awake until midnight.

I always fall asleep in history class - it's so boring!
