For the past month this has been our kitchen table. Nate has been working on a science project involving plants and magnetic fields. There are 90 plants in this picture, three per pot and ten pots per variable. The pots in the foreground have battery powered electromagnets, the next section has permanent magnets, and at the far end the plants have neither electro nor permanent magnets.
Monday was the end of the whole thing and I was very happy to see the plants grow. Theoretically I could have kept a few going over the winter and planted them next spring.
No.
The plants were already starting to lean and wrapped themselves around each other. It was quite a challenge for Nate to tease them apart for the final data collections. It was easier for him to cut each plant flush with the soil and then take all of the measurements. I could see differences between the two groups, but Nate hasn't crunched all the data yet. My guess is the the electromagnets stimulated the most growth.
