The 21st Century Science: STEM Careers of the Future and The Annual Career Fair exposed students from Ware Shoals High School and Greenwood School District 51, SC, to the multitude of career options in STEM, ACS, Savannah River National Laboratory (SRNL) and provide valuable insight into the educational and vocational pathways they would need to pursue to obtain a career in their fields of interest.

Look at a raw potato and you might visualize tater tots. Potato chips. French fries. A baked potato dripping with butter. The Martian character Mark Watney looks at one and sees survival.
Readers of Andy Weir’s The Martian, including those who have joined the currently running American Chemical Society (ACS) ChemClub virtual book club, will recognize the humble potato as a key plot item. It’s a major part of Watney’s saga to survive until a possible rescue from his predicament of being left for dead on the planet Mars. He calculates that his remaining food will not provide him with enough calories to last until rescue. (Watney “spares you the math” in the book, but you can do the math yourself with the Think Like a Scientist: Back of the Envelope Calculations handout from the virtual book club resource packet.) His solution is to turn his living space into the first Martian garden, using raw potatoes sent with his mission team to use for a Thanksgiving meal as his planting material. The challenges are many.
What are the chances for actually growing food on Mars, beyond the science-based fiction of the book? A view of the planet’s dry red landscape might suggest the chances are slim. Dig deeper into the issue using additional free resources from ACS.
ChemMatters is a magazine designed for high school students to help find connections between chemistry and the world around them. The most recent issue includes the articles “Growing Green on the Red Planet” and “Open for Discussion: Surviving on Mars.” The two pieces discuss the extreme conditions astronauts would face on Mars. Although “Growing Green on the Red Planet” states that it is the most habitable planet in our solar system besides Earth, humans (and any plants) would face extremely cold temperatures, an atmosphere of 95% carbon dioxide, a lack of readily available water, and less than ideal soil. The article also touches on plant growth experiments done on Earth using volcanic soil from Hawaii to simulate Martian soil.
Readers can also take advantage of two accompanying resources for “Growing Green on the Red Planet”: a Teacher’s Guide and Background Information. The Teacher’s Guide is packed with tools you can use with the article itself and extensions to take the article topic further. You’ll find an anticipation guide, student questions and answers, possible student misconceptions, links to lesson plans on the science of soil and the chemistry of fertilizer, and more. I found the beginning of the Background Information particularly interesting. It summarizes the spacecraft that have been used to study Mars and the resulting data/information obtained by each. The first was in 1964, and a future mission is in the works.
The ChemMatters site also highlights the video “Can We Grow Plants on Mars?” from D News. At three-and-a-half minutes, it could be a good way to kick off a discussion of the chances of Martian gardening.
Together, these free resources are ways to link science fiction from The Martian with real-life connections to Mars and its possibilities.
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”
