Research indicates that preschool classrooms have few planned or spontaneous science activities (Brennemann et al., 2009; Greenfield et al., 2009; Nayfield et al., 2011). Tu found that only 50% of early classrooms have a science center and when there is a science center, teachers spend little time in them (Tu, 2006). Why do you think these facts are true? 2. The early years provide the foundation for later science learning. Historically and even currently, girls, minority children, children with disabilities, and children from low-income families are often excluded from science related jobs and education. Why do you think this is true? What can be done to change this trend?
