Old Microscope Sparks New Idea for Kids' Science Club
When he was a child, Center research ecologist Bill Hargrove burnt off his eyebrows making rocket fuel, blew up a sealed jar of cultured yeast, and started a bathroom fire while doing sterile transfers for a carrot tissue culture. Fortunately, he survived his early scientific experiments and is now inspiring a new generation of young students.
Hargrove and his wife, Dr. Rebecca Efroymson, are pioneering an extramural science club for 4th and 5th graders at Haw Creek Elementary School in Asheville, North Carolina. Each monthly club meeting features real-life scientists who lead lively discussions and activities about diverse scientific topics.

During the first club meeting last year, students looked at living creatures found in drops of pond water through a light microscope—Hargrove’s own childhood microscope. “I used to spend hours in junior high school looking at protozoa through that microscope. My family got used to having stinky jars of pond water on every available window sill,” says Hargrove. Students also controlled a scanning electron microscope located in a different state over the internet to observe insect specimens that they had mailed weeks earlier to the national Bugscope project.
At other meetings, students have built simple robots that could move and follow a light source; explored rockets, airplanes, and space, including outdoor rocket and airplane demos; and delved into electronics. Students have also surveyed archaeology, constructed pickle and lemon batteries, learned about biofuels and solar power, and have even touched human brains as part of a recent meeting focused on psychology, following a discussion about respectful conduct and ethics.
One might wonder why Hargrove and Efroymson—both busy researchers and parents of two—commit their extremely limited spare time to the club. In short, they wish to share their passion for science with others. They hope to excite students about the possibilities of careers in science, especially those underrepresented in scientific fields, including women and minorities. Hargrove explains that kids today belong to a “software generation” and feels that free range tinkering is critically important for developing minds. “I think that kids often don’t get any ‘feel’ for science. But if they can experiment in a safe environment, they realize that science is just normal, regular stuff. No magic at all. Then the fear is gone, de-mystified, and they can get on with learning.”
