First graders in Mrs. Dorris‘ classroom learned about structure and function in Project Lead The Way.  After reading the 3 Little Pigs, students constructed their own straw, stick, or brick simulated homes.  Mrs. Day, PLTW instructor, tested their design with “the big bad wolf” blowing machine.  Children had to analyze and improve their designs as part of the engineering design process!  Little eagles are becoming great thinkers at Glenns Valley!
