The reforms call for elementary science that engages students in meaningful and relevant learning opportunities for all students. While science lab facilities are common to middle and high school, in elementary schools, science is typically taught in the regular classroom. Elementary schools across the nation, however, have devoted financial and other resources to establishing separate laboratory facilities for science. How do these facilities support the delivery models for elementary science instruction and aid in meeting the vision of the reforms? The lack of research in this area should be addressed to enable districts to make informed decisions about whether to allocate funds to establishing separate facilities or equipping regular classrooms for elementary science instruction.
