Our ACS ChemClub (Buena Science League) at Buena High School in Ventura, California, has developed an exciting outreach program for local elementary and middle schools. We travel to the local middle schools and spend the day presenting demonstrations to their science classes. In a day, we typically see six classes, with about thirty students per class. Depending on how we travel to the middle school, we take seven to twelve Science League student demonstrators. We also host an annual Science Show for elementary students in our large auditorium, usually presenting three 40 to 45 minute shows to an audience of 200 students per show.
We also host themed Family Science Nights each quarter for elementary and middle school families. We arrange demonstrations for viewing and hands-on activities for participation. We try to choose demonstrations and activities that relate to the chosen theme. Fourth through eighth grade students attend for an hour and a half in the early evening. About 30 students came to the last one, with a superhero theme. We have about 15 students participating from the high school, and they are pretty committed to the events. Their responsibilities are to learn how to perform specific demonstrations safely and to explain the underlying science.
While the ChemClub Virtual Book Club is about the printed version of The Martian, it would be hard to never mention the movie version. The movie gives the characters faces and voices making it more appealing to a wider audience. We’ll explore resources for both the film and the novel in this blog post, but remember to share your thoughts with us in the comment section and on Facebook or Twitter using #ACSChemClubBook.

I don’t even remember why I chose it to read. Maybe it was random buzz on the internet. I mainly needed something to kill time on a cross-country flight. On the plane, I cracked it open. Just a few pages in, I knew it was different. An interesting science fiction story, but it was something more that appealed. It was how science and problem solving were woven directly into the plot of The Martian at nearly every turn. Continue reading “Science in Fiction”
The Art of Estimation
When I was in high school, in the days before electronic calculators were available, we learned how to use mechanical slide rules (see ChemMatters, April 2004, p.4) for our calculations. While they were great for getting a good answer to math problems, they didn’t keep track of the decimal place. That had to be done by keeping track of an order of magnitude estimate of the answer.
