The middle school science fair is Friday. The event, which will feature the hard work of the 5th and 6th graders, will include original scientific experiments. Students in Ms. Dobler and Ms. Dorsey’s classes have been conducting original experiments, using various household materials to test their hypotheses. They have collected and analyzed their data and created graphic illustrations of the results to present to outside visiting judges on Friday. It is a great chance for children to boost their public speaking skills and see science at work.
