Investigations constitute just part of the day or week and connect learning around a relevant science topic for several weeks or months. The duration of the mini-investigation is shorter than a full investigation, generally lasting a week or two. This shorter duration allows teachers and children to focus time on less substantial studies of topics that are meaningful to children and families but may not be worthy of the time commitment associated with a full investigation. Daily routines are the common structures of the day that provide young children with the comforting predictability that is part of a quality early childhood program. In-betweens are the times that ACCESS teaching teams take to reflect on their practice and make intentional decisions to meet the needs of children, staff and their co-teachers.
