Why did I drop the photosynthesis lab in AP Biology?
Tip: "I had dropped the photosynthesis lab when I first started teaching AP Biology out of frustration. When the lab manual first came out (OK, I'm dating myself here) and the lab was included, I sunk into a short-lived funk (we were on shortened periods that day so I didn't have a full prep period). Then I had an epiphany.
Which is the best source of chloroplasts?
This was the first case in which a specific physiological or biochemical function could be ascribed to a particular organelle. A number of different plants may be used as sources for chloroplasts; spinach is usually the most readily available and most dependable. Get the freshest spinach available.
How do you put plant pigments on paper?
Just have the students place them on the paper, lower epidermis against the paper, and press the pigment onto the paper. I like to use the rounded tips of scissors or the blunt end of forceps to get a nice even line. Another good thing is that it only takes a couple of leaves for the entire class."
