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 first 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 A, students move through the lessons below to answer the following Essential Questions:
- What patterns do you observe in your tree over time?
- What evidence can you find of how weather impacts your tree?
- How can you use those observations to predict how weather might impact your tree in the future?
