Your ultimate goal for the day is to get out of school. Before you do, however, you're looking to get your bag out from the classroom where you left it.

That is, however, not the only thing going on in school today.

You've uncovered a major power struggle in the Chemistry Department, where Mrs. Desai is brewing something to give her full control of the lab. She's asked you to get for her gold, methanoic acid, and nitrochalk. So far you've given her the gold and the nitrochalk.

The teachers in the physics lab have built a time machine, and they want you to go back in time to get some "dead organic matter." All you've really learned so far is that they definitely do not want leaves.

Hungry Mrs. Awatif is looking for something wriggly to eat and wants you to help her out. (I have what she wants outside her door but it won't let me bring it in the room.)

Mr. Anand over at the computer lab is having trouble with a game and is looking for your help.
