Applying for an undergraduate research mini-grant

Hello! I am a senior in college applying for 'mini-grants' offered by my university to support the lab that I have been a part of for several years. My project chiefly relies on reaction time and a little bit of coding, so I don't really have any high costs myself, but I would like to apply for miscellaneous lab needs as well as to put it on my CV. I'm concerned with 1. Is it ethical? And 2. what do I even put in for budget justification? I can list a few things needed by the lab, but they're not directly tied with my own research.

Thanks for the help!
