Sixth graders are investigating mold growth in science class after collecting samples from different locations in school. Using the scientific method, they have been analyzing the results over the course of a week. Locations that students tested include a window sill, a keyboard space bar, a bathroom sink, a toilet seat, and the gecko cage in the science room. They transferred their swabs to a petri dish and then watched to see what would grow. They measured the diameter of any mold colonies and recorded their observations onto a data table. Sixth graders analyzed their data and wrote a concluding statement that summarized their findings.
