Biomedical Club proposal

Hello everyone
I’ve been trying to initiate a club of bio medical research in my school. I have a club adviser and spoke to the vice principals who said all I have left to do is write a “proposal” so it can be board approved. She said to write in the proposal the purpose of the club and why it should exist. Please leave some ideas of what my proposal should include. My club is allowed to meet as of now, but if we wish to go on field trips we need to be board approved. I am planning to have the club members use the lab facilities my school offers, and conduct bake sales to raise money for the American Cancer Society. I am just a little bit stumped on how I should write my proposal, and I would appreciate any other ideas that my club could possibly do.
