How do you teach dozens of gradeschoolers basic science principles? Well, one way is to disguise the lessons as a big, fun disaster area. This spring, Drs. Courtney and Tim Griffin led a team of OMRF scientists to wage a guerilla science assault on Oklahoma City’s Wilson Elementary School. From bag bombs and cloud bubbles to “elephant toothpaste” (a foamy substance caused by the rapid decomposition of hydrogen peroxide), students conducted a battery of simple experiments using common household materials. In the process, lots of eager young minds got an ooey-gooey, up-close look at science.
