This arrangement of lessons moves students through the stages of exploration, explanation, and elaboration. True to constructivist pedagogy, students move through these phases in a linear fashion as they begin by testing ideas to develop knowledge, and then modify and refine those ideas as appropriate to answer questions and extend conceptual understanding. PLT recommends moving through each of the following lessons sequentially, to scaffold student learning over time.
In Level C, students move through the lessons below to answer the following Essential Questions:
- What can we learn about trees and their habitats by closely observing them?
- What patterns can we see in trees over time?
- How are habitats alike and different?
