I think you can skip the water testing or any other attempts to get her to change the water. If she was going to do it, she would've done it by now.
Just volunteer to do it yourself, and maybe organize some other students to help. When I was a kid I would've loved to do something like this. A chance to play with water? Yes please!
It takes less than 5 minutes to do a wc. Get one of those large siphons that drains quickly. It is a fun process I bet some of your classmates would be happy to help.
Other than water changes, you can also lower the number of fish as well as add in plants like lucky bamboo, golden pothos, and floaters to quickly lower ammonia.
If you're savvy with social media, you can post some requests on Facebook and/or craigslist. I bet lots of people will be willing to donate equipment to you. Just be careful though -- always meet those people via your parents or teacher or some trusted adult. NEVER do any donation stuff on your own there's some crazy people out there.
