The purpose of Tremendous Trees or Tree-mendous Trees, as it is sometimes called, is to encourage students to use inquisitive and creative behavior, to think like a scientist. The module extends the Essential Strategies of Attributes and Questioning that were introduced in Kindergarten and First Grade. Students use questions to approach problems and identify attributes to sort, classify, and make inferences to create analogies on observational data about our world. This module is meant for all students. The classroom teacher should work with a specialist or special educator to find or develop alternate activities or resources for visually impaired students, where appropriate.
