An HOS in USA treasure-trove

Many of you may know the previous incarnation (in-Web-nation?) of Clark Elliot's extraordinary database on the history and historiography of American science. It has just received a face-lift and is better than ever. Check it out here.

I am particularly impressed by the 19th century chronologies, which are even complete enough to note the foundation of the US's first permanent agricultural society. See for yourself.

BOOK REVIEW: Vanessa L. Ryan, Thinking Without Thinking in the Victorian Novel (Baltimore: Johns Hopkins University Press, 2012) ——————————————— Science and (the study of) literature are growing closer together. From  Stanford's Literary Lab  and a recent New York Times piece on the Digital Humanities  to reading Austen in an MRI machine  and so-called " Literary Darwinism ," there's both controversy and a certain cache (and maybe even a little cash) in bringing scientific techniques and the study of literature closer together. This is your brain on Austen ( http://news.stanford.edu/news/2012/september/images/mri_reading_news.jpg ) So what about the study of science and the study of literature?

Scientific Comparison Writing

My friend, Kip Bisignano, (a Delta/FOSS Sales Rep for Virginia, Maryland and DC) came to play with my class this week. We are presenting together at the Virginia Association of Science Teachers (VAST) in November on reading strategies and science. So yesterday, we used the book and the strategies with the class. The results were amazing! We started the day by having the kids read the book: Blue Whales and Buttercups by Seeds of Science. It is an excellent book that has the students reading about how animals and plants are similar and different. They eventually get to the point that they are all related - due to the fact that all living things are made up of cells. My students loved the book and we had a great discussion!

Chocoalate...Sink and Float

What's better than chocolate?  not much! Here's another experiment brought to you by Candy Experiments.   Most candy sinks in water, because sugar is denser than water.  But some candy floats. Why? This experiment is so easy...all you need is some leftover chocolate candy and water.  Drop the candy in the clear glass and observe what happens.  Here's what Loralee at Candy experiments says is happening: "Some kinds of candy, such as Kit Kats, 3 Musketeers, and marshmallows have air trapped inside. This makes them float.  " I have created another recording sheet to go along with this experiment!  Hope you can use it!
