Sorry for the failure to blog yesterday ... lots going on this week ... two labs this week in AP and I am helping with the Allen County Beekeepers Bee School on Saturday ... starts at 8:30 and weather looks good. If you want to some great bee info and look at some weird equipment (courtesy of Kelley's Bee Equipment / Clarkson, Grayson County) you should stop by.
We wrapped up AP Lab #4 / Photosynthesis today in our AP classes ... great results from chloroplasts extracted from turnips and mustard ... not exactly what the lab calls for but they were the freshest (and not very fresh) greens in the produce section at Food Lion. I added some leaves from some of the plants I keep in my classroom. The paper chromatography of pigments from geranium leaves yielded great results!
Students used our two spectrophotometers and that also went well.
Tomorrow is a short session of biochem poker to review biochemistry and the start of cell biology. Thursday and Friday is our Diffusion / Osmosis Lab (five labs in one). We will demo some technique for this lab tomorrow. We are trying to complete all 12 required labs before Spring Break.
In Selected Topics in Science, we did a paper chromatography lab to separate different inks found in black ink ... The Who Killed Waldo Lab ... All but one group was able to solve the mystery! Tomorrow is cell biology and some ACT prep.
This last weekend I was able to prepare a couple of small fields and plant hairy vetch (a legume) and clover. Hopefully it will benefit our honeybees in the future and I am sure our deer will enjoy some for the their salads!
Also ... I have been hearing some sandhill cranes on the move between Long Creek and Barren River ... a sure sign that Spring is getting closer ... and I for one will be happy to see it arrive!
