This step-by-step series from Bethany Brookshire and the Eureka! Lab blog explains how anyone can do research in science (or engineering) and do it right. The experiments here may feature cookies, but the same steps apply whether you’re interested in making a plane fly further, developing a safer pesticide or studying changes in the night sky. All the directions are delivered in bite-size entries so that you can design your own engaging research — for a science fair or just for fun.
