Your ultimate goal for the day is to get out of school. You're not really sure how you're going to accomplish that, but at least you've got your bag back.

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 a potion 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 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.

My biggest problem is that I can't figure out how to find the gold or the methanoic acid, which I think is baking soda. I'm hoping that if I find those things, then I can figure out the rest. Any help would really be appreciated!
Thanks!
