Wow! You guys have figured a lot out, that's great :)
I think your procedure sounds good! There are a couple more things you might want to think about too:
1. How often do you want to add the treatments? I think adding fertilizer and Gatorade everyday might overwhelm the plant, but adding them every second or third day (with plain water on the days between) would probably work great!
2. All the pots should be the same size or very close! This way all the plants will be in the same environment, and the only thing we're changing is our treatments.
3. Buckwheat and nasturtium are very different plants, and so comparing if buckwheat grows more than nasturtium might not tell us much about the liquid treatments (but it will tell us how the plants have different traits!). But, I think it will be super cool to see if we see the same trends in both plants due to the liquids! So this sounds like a fun idea!
Do you guys have any questions or concerns about the methods so far?
Liaison Cameron nominated this mentor for being "very responsive, attentive, and thorough! Easy to talk to and students respond well."

PlantingScience F2 Grant Award
We are thrilled to announce that we have been recently been awarded a 5-year, $3.9M grant from the USA’s National Science Foundation. The new project extends previous research on PlantingScience, which showed improvements in student achievement and attitudes toward scientists. This grant will include developing and comparing an online format for collaborative teacher/scientist professional development to an in-person format, including comparing outcomes from students of teachers prepared through the different formats.

“I liked that we didn’t know what was going to happen before we did the experiment. Instead of being taught something and then just doing an experiment to prove it, we made an attempt to find out what would happen ourselves.”
- PlantingScience Student
“At every opportunity, all involved kept reminding my students of the process that real science requires. This helped me to convince my students that they are really doing science - not just play acting until some future date.”
- PlantingScience Teacher
“It is a lot of fun interacting with students from an age group I don’t have the chance to spend a lot of time with. It is a good reminder of where public knowledge of plant science stands, and a great opportunity for me to practice explaining key concepts in a simple and straightforward way.”
