This sequence of instruction was developed in the Growing Elementary Science Project to help elementary teachers who were working remotely.  We developed a short storyline that ties together a few sessions to help explore a specific concept.  We tried to include some activities that honored and included the student’s family and experience, and some that included the potential for ELA learning goals.
Students view a couple of videos and record what they notice and wonder about how plants change as seasons change. Students take a walk with family members to search for evidence of changes due to weather in their neighborhoods.
It is part of ClimeTime - a collaboration among all nine Educational Service Districts (ESDs) in Washington and many Community Partners to provide programs for science teacher training around Next Generation Science Standards (NGSS) and climate science, thanks to grant money made available to the Office of the Superintendent of Public Instruction (OSPI) by Governor Inslee.
