Hello Dr. Miller,
We have successfully preformed the leaf flotation protocol, and, as expected, adding carbon dioxide to the water helped the plant preform photosynthesis, as CO2 is a necessary ingredient for photosynthesis to occur.
Now that we've learned more about that, we are beginning to design our own personal experiments on photosynthesis using the question "How does ____ effect photosynthesis?" Some of our ideas include adding carbonation, acids, milk, or vinegar to the water and testing to see if the leaf flotation protocol is still effective. Another option would be to expose the plant to music, as there have been studies saying that plants grow differently when exposed to certain genres of music.
If you have any input on which of these options may be the best to experiment with, or if you have any other suggestions, please let us know!

We are currently looking for new teachers for our Spring 2021 Session!
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. Read more here.
Each week we feature some of the best projects of the current session here. Go to the Star Projects Gallery to see all the excellent work by star teams in past PlantingScience sessions.

“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.”
