Remember those old diagrams in your grade school science text books? I used to flip through each chapter trying to find the coolest images, but was continually disappointed when I was forced to squint at tiny illustrations. As I continued through school, however, I found myself drawn to large illustrations that conveyed information effectively and in plain language. I read The Way Things Work every night before bed. The blend of science, art, design, and communication, was intriguing, and I suppose part of why I entered the field of GIS and mapping.
From subway maps to government information pamphlets and all across digital and print media, illustrations are an engaging way to convey information.
NASA’s Jet Propulsion Laboratory (JPL) agrees, and their new citizen science project, JPL Infographics, calls on you to be the scientist-artist in charge of communicating their cutting edge science. NASA provides a huge library of amazing high-resolution space images, 3-D models, and lists of interesting facts for you to piece together into your very own Infographic. You can browse other user submissions for inspiration and then upload your finished image easily online.
Head to the JPL Infographics project to learn more. It is free to join, and registration is easy! This is a really fun and challenging project, and your work will be used to educate and inform others about cutting-edge space exploration.
Fire up both sides of your brain and create some educational space art!

For those of you who watched “Raiders of the Lost Ark” and wondered how you could go searching for ancient artifacts yourself, here is your chance to get in on some archaeology action. The Calico Early Man Site, located near Yermo, California, is starting its fall digging season this weekend (October 2 and 3) and they welcome volunteers to help with their unearthing efforts.
JK Mueller, the organizer of the dig, let us know what first-timers should expect. When you first arrive, she says, you’ll see on the ground “chips and artifacts scattered everywhere, mostly made of chalcedony, an orange glass-like material.” She assured us that diggers will learn on the job “how to sift for artifacts and how to distinguish an artifact (human made) from a geofact (nature made).”
Saturday night lectures cover a wide range of related topics, from geology, gemology, and tool manufacture to climate. Volunteer effort is central to keeping the site running, and helpers have made many significant finds. Just last season, says Mueller, “The Friends of Calico president found two projectile points in the piles of mined bentonite clay right outside the main building. One still had animal hair and leather string attached [and was] dated at 1500AD.”
This archeological site has delivered interesting finds—and scientific controversy—since digging began there in the 1940s. From the mid-1960s until his death in 1972, Dr. Louis S.B. Leakey, famous for his research in evolutionary anthropology, directed the excavation. Of particular debate are rocks found at the Calico site that look much like prehistoric tools, and that are thought to be around 200,000 years old. While the tool-like rocks may appear to have been made by people, other scientists have argued that they could have acquired their shape through typical geological processes. If these rocks are indeed human made—that is, artifacts—rather than a result of geologic pressures—geofacts—the finding could push back the traditionally accepted date of human entry into the Americas (about 11,000 years ago) nearly 20-fold.
To see for yourself, and to learn more about the science behind the dig, head down to southern California. There is no cost to volunteer, but if you wish, you may join the Friends of Calico, a non-profit organization that helps finance ongoing scientific projects. It’s also helpful, notes Mueller, to bring “gloves, scarves, jacket, hiking boots to travel the last few feet of rough ground, [as well as] magnifying glasses and knee pads.”
And be prepared to make friends. Mueller says, “Volunteers are loquacious, energetic, and personable, and love to talk about varied topics and to learn at all ages. New volunteers almost always feel right at home.”
