That can be really hard to tell without really precise environmental conditions, like a growth chamber. I mentioned to another group that flowering plant seeds come packed with nutrition for the embryo called endosperm. Not every seed has the same amount of endosperm in it. A seed with more endosperm would likely grow more quickly at first, even with identical conditions! In other words, environmental conditions might be a little different or some seeds could have had more nutrition in them than another.
A nice explanation for why there might be variability in the students' results

We will soon be recruiting for new teachers for our Spring 2022 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.”
