Theresa Delancy’s third grade class at Mariposa Elementary School practiced being scientists as they explored scientific tools. The students rotated through six centers using tools like a pan balance, measuring tape, thermometer, graduated cylinder, eye dropper and hand lens. The students worked in small groups and performed an experiment at each of the six centers. They recorded their observations and collected data in their science journals just like real scientists do in the lab. Pictured are Joshua Pierre,left, and Juan Navarro.
