Thanks Hedi. And thank you for your email reply and invitation to the network. I still have some questions about using the Jiffy pellets to grow fast plants. Are there any step-by-step instructions for using them that includes how to handle "fluffing", planting depth, vermiculite, fertilizer, wicking... etc?
The physiology resource isn't it. It had lots of nice illustrations of each life stage. Perhaps the curriculum has been changed since I looked at it. It seems much more text dominated now, less illustrated. Thanks, Greg
The purpose of our experiment is to develop an inexpensive approach to monitoring the growth of the plants by measuring the light that gets past the leaf canopy. We are also trying different types of lights, largely because the light they produce is different and measures differently. Since we are using a measurement approach that requires the use of a laptop, we have also set things up so we can control the measurements from anywhere and can also watch the plants on webcams. We get teased for 'watching plants grow' but you know this is really a lot of fun.
Thanks Hedi. I am writing some curriculum to parallel research being done by an ecologist at UCSB, and I think fast plants are the way to go. Do you happen to know the germination rate of these brassica plants (that is, if I plant 10 seeds how many are expected to pop up?).
The first teacher to plant I think will be Reane this Friday. I'll talk with her and see if we can try this with her students. If she does we'll keep you updated on how it goes. Enjoy NSTA we have quite a few teachers from ASSET that are attending also.
I have some info about mini-garden necklace supplies. Go to http://www.usascientific.com/index.asp?PageAction=VIEWPROD&ProdID=545 for the tubes. 500 multicolored tubes for $13 (you can get clear ones too). I finally found 50 1 ounce clear shot glasses at a dollar store for $1.99 and they take the Solo brand caps--easy to find at any party store.
I appreciate the reminder emails to check out the site and today I got some great ideas. I would like to try the molecular paternity testing. I saw the experiments of the seedlings growing in some type of gel medium. I do the simple geotropism experiments in film canisters but I'm interested in maybe trying this with my AP Bio kids. Where can I find the recipe for the media shown in the pics? Also, I sent you a copy of my Butterfly experiment paper that I intend to send to ABT or The Science Teacher. I have taken a bunch of pictures and they turned out pretty well. I could blog about it on this site if that would be helpful.
