1) The teacher in the video is supporting the students in conducting investigations, making explanations, supporting claims with evidence and reasoning (CER), and drawing scientific models. Describe four key ideas that a teacher would need to know to be able to support students in doing this work. Think about listing ideas you might want to remember in the future if you were to teach this unit. For example, "a scientific model can help predict what would happen next for a given phenomenon." is more useful than "I need to know about scientific models."
