Now Blogging at GeekMom with Mythbuster Kari Byron!

I've been busy the past few months helping to launch GeekMom, a site dedicated to moms who want to share their geeky passions with their kids. To start us off, we've got MythBusters host Kari Byron writing about her new adventure as mom to a one-year-old girl. Kari is also the host of the new hour-long kids' show Head Rush. Check us out!

And I'll still be blogging at GeekDad, so be sure to stop by there too!

Comic Book Elements

"OK, 103 -- Now you're going to turn him into pure copper!"

Coughs, colds and catching up have kept us from doing more experiments. Hopefully we'll get back to it soon.

In the meantime, while searching for info on Ferrofluid and Magnetic Slime, I came across this nifty site. The Periodic Table of Comic Books links each element to its appearance on the printed page. From the University of Kentucky Department of Chemistry!

Access to Chemistry at Oxford

Oxford University in England has joined the list of colleges offering FREE online courses to the public. Their Access to Chemistry website "provides an excellent resource for prospective applicants to learn more about Chemistry at Oxford from anywhere in the world."

When you click on Pre-University Course, you can page through teaching material based on the book "Chemistry, Matter and the Universe" by Richard E. Dickerson and Irving Geis -- complete with helpful animated illustrations. Here's the introduction:

Many reasons can be given for studying chemistry, ranging from, "It is an intellectual adventure," to "I can make a good living at it," or even "It is required for graduation."

But the most valid response is simple. Chemistry is the study of how matter behaves. We have only one world in which to live. If we want to know how we can change it and what we cannot alter, or even simply to appreciate what we already have, then we must know how it works.

Chemistry is the subject that tells us this. Physics may teach us fundamental facts about elementary particles, matter, and energy, but it stops short of drawing conclusions about how the different kinds of matter around us change and react. Biology describes the large-scale behavior of organisms, which at their core are elaborate chemical systems. Some of the most fruitful advances in biology in the past two decades have come from a thoroughly chemical approach. If we can expand the concept of chemistry beyond our present limited and inadequate knowledge, then biology fundamentally is the highest form of applied chemistry. If chemistry is the study of how matter behaves, we must not forget that we, ourselves, are an integral part of this material world.

This is all part of Oxford's Virtual Chemistry Virtual Laboratory, which includes a 3DChem (a molecule of the month website), LiveChem (a library of nearly 300 videos), and a Webcast Lecture Series of courses such as Dr. Hugh Cartwright's Entertaining Chemistry. Looks to be an excellent resource!

New and Improved About.com Chemistry Page

Today I'm making up a worksheet of experiments to do later in the week about solutions and precipitates, based on our "spine," The Joy of Chemistry. While I find the book helpful in organizing my lessons (and, of course, providing all my information), it hasn't worked for us as a read-aloud. So what I do is go through the chapter I want to cover, find the demonstrations that I think we can do (based on availability of materials and risk level) and type them up. Surprisingly, despite the analogy the authors make to "The Joy of Cooking," the "recipes" in their book are integrated right into the text. So unless you're reading it surrounded by your fully-appointed and ready-to-use laboratory, it's a little hard to do the demonstrations just using the book. To make them usable for us, I've been putting them into recipe form -- Explanation, List of Equipment and Ingredients, Directions. I told both co-author Monty Fetterolf and his publisher's PR person that if they don't come out with a new edition, I'm going to write my own companion volume when I'm done!

One other thing I've been doing is finding similar, related experiments to add to, modify or replace some of the demonstrations in the book that I feel could use improvement (or just can't resist tinkering with). My main source for this information has been Anne Helmenstine's Chemistry section at About.com. I just scooted over there to see what she had on our upcoming projects and saw the site has gotten a makeover. It's cleaner looking, and the ads have been toned way down, making it easier to find what you want. The current lead story is about making a "Do It Yourself Chemistry Lab." One interesting question discussed: "Is It Safe to Use Kitchen Glassware for Chemistry?" Helmestine writes:

I remember a chemistry experiment in analytical chemistry class where we were asked to take a piece of glassware from the storeroom, get it as clean as we could, and then the instructor rinsed it with acid and water and showed us the spectrum of the stuff that was still on the glass. As you would imagine, there were heavy metals and some dangerous organics. He was trying to illustrate that even 'clean' glassware isn't inert and can mess up an analysis, but it also went a long way to explaining why we shouldn't make coffee in the lab. Using dishes for chemistry projects isn't the same thing, but it may not be safe.

Her conclusion? Yes and no. "If I make slime or a smoke bomb I'll use dishes, but I'll be careful to rinse them immediately so that no one accidentally eats borax or saltpeter ... but there are exceptions. For example, I wouldn't make green fire in cookware. "

I know a certain 12-year-old that will appreciate my saving those particular links.

Update: Anne Helmenstine left a nice little comment to this post. And I couldn't asking why the little white dish in the green fire photo above looked so much like a Corningware ramekin. Her reply:

Um... (confession time)... that's because it is a Corning ramekin. I think what I said was I wouldn't use ceramic cookware, not that I didn't, lol. When I tried that project, I did not expect the methanol in the Heet to burn quite that hot. I'm surprised the ramekin didn't shatter. For future tests, I used a stainless steel mixing bowl.

Just so you know.
