In the fall of 2004, United Way engaged TERC to develop a curriculum for their “Math, Science, and Technology initiative” (MSTi). The program kicked off when 50 students at three agencies signed up for the Muscles, Lungs, Blood, and Gutscurriculum. By the next fall, the program had grown to include close to 300 middle school students. Gaining comfort and experience teaching hands-on science, the afterschool staff are helping students see how science is a part of their life and their future.
