A school is about to undergo major renovations and new construction to handle a growing student population. So some science classes and labs are assigned to other parts of the building temporarily. Most teachers are excited about the opportunity to help design the new facility—but many are unaware of the challenges that lie ahead. Therefore, science teachers and their supervisors need to get on board early in the planning stages for new construction and renovations. This includes planning for safety-smart temporary lab facilities. An alternate instructional site where all legal standards and professional best practices can be addressed is critical.
