This session is part four of four on the New Science TEKS series for third through fifth grade. In Organisms and Environments, participants will continue the journey to understanding the new science and engineering practices (SEPs) and updates to the 3-5 content strands. SEP topics will include the engineering design process, recurring themes, a deep dive into concepts, input and output tables, and graphic organizers. Science content topics will include plant dormancy, fossils, animal adaptations, life cycles, deep roots and waxy leaves, life processes, and animal instincts vs. learned behaviors.
