6 Feb. Science 8 History of the discovery of photosynthesis continued

Notice: If anyone wants to help some local students with experiments and simple science activities, please let me know. This afternoon a group of students from Each One Teach One will be coming to M313 to do some chemistry activities. Friday the Reach Out kids will be building and flying air-pressure water rockets. Saturday morning Hope Club will be visiting the Hope Foundation School for the Dr. Seuss story of Bartholomew and the Oobleck and exploration of Non-newtonian fluids. Upcoming are visit to the Blind School and to Ms. Madhu Kapoor’s project Yamuna Kids. Helping can be a great way to combine Service with Science. We would love to have your assistance. See me for details.

Bring in some “wild” seeds and or wild stems (fresh) and see if they will sprout and grow. During this next phase of our study, grow a “wild” and food/garden plant. Keep track of its growth. Use this plant to contemplate photosynthesis. Pick out a campus tree that you see every day or that you really like or wonder about. Visit this tree regularly to thank it for the service of taking in carbon dioxide, releasing oxygen, providing food for various organisms, for fixing nitrogen (in the case of bean family plants and the Casaurinas), for giving shade, for protecting the watershed, for moderating the climate, for providing shade, and for adding beauty to our campus environment.

Finish poster / cartoons of Jan Baptiste van Helmont

Here is an interesting critique of various interpretations of van Helmont’s experiments in the history of botany : http://helmont1.tripod.com/hersheypsb49-3.htm

“He (von Helmont) misses something. . .” (8:39)

Jan Ingenhousz

As an individual choose a creative way to express Ingenhousz’s contribution to the story of photosynthesis. A poem, a play, a single drawing (rather than a cartoon), another cartoon.

Apothecary–making remedies from plants

(Find out about Phlogiston theory and how it influenced scientists working with gases at the time of Ingenhousz.)
