“July 23-24, teachers met in the Science Center on the campus at Wisconsin Lutheran College for Operation Science training sessions. The first day, the teachers took part in using the skills of science (observing, communicating, measuring, inferring, making models, and using the scientific method) as they participated in several hands-on lessons. The second day, teachers received training in a unit of their choice. (Units offered were Fabric, Organisms, Balancing and Weighing, Rocks and Minerals, Sound, Electric Circuits, Mixtures and Solutions, and Motion and Design) Teachers spent the day experiencing hands-on lessons that are part of each unit. Once teachers receive this training, they are qualified to rent the unit for their own classroom to use. “
