Hi Natalie and welcome to Scibuddies.
'Medicine' is a pretty broad area for a project. You will have to narrow it down a lot before we can help you set up a good project. One way to do this is to use the Scibuddies project idea resource:
https://www.sciencebuddies.org/search?v ... n+medicine
Take a look at the examples of projects in the list and see which ones really interest you, and also think about what you would be able to do in the time you have and with whatever resources are available in your school lab.
Post again when you some more specific ideas about a project and we can help you narrow it down. Please remember to put your next post on the same thread as this one so everything stays together. It makes it much easier for us to follow the Q & A when they are all together in ONE posting thread.
Good luck!
Sybee
