I see what you mean about that little one! It looks like its stem isn't strong enough to hold up the leaves, meaning it probably is dehydrated. A dehydrated plant means there's not enough water pressure (known as 'turgor pressure') for it to stand upright. You can think about turgor pressure as being similar to the air in a balloon keeping it full, and when there's not enough the balloon goes limp/deflated. Since we added so many salts and sugars into the soil, water leaves the plant to try to equalize the concentrations between the outside and inside of the plant (but this is more than you need to know! You'll probably learn more about these processes in high school ).
However, the other ones look like they're doing well! It will be interesting to see what the Gatorade treatment results look like at the end of our experiment!

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.”
