This is a complete lesson to teach night and day at the kindergarten level, but could probably be used in other grades as well. It includes a step-by-step lesson with 5 e's, standards, objectives, materials needed (description), intro, lesson, assessment, conclusion. The lesson is great for all styles of learners. It incorporates basic literature integration, followed by students working in groups and pairs to sort objects as belonging to "night" or "day", has an edible model idea for students to enjoy, and culminates with songs. Students will love this science lesson.
I am a current 5th grade teacher, but also have experience teaching 4th grade inclusion, and additional field experiences in kindergarten and third grade. In addition, I have been a substitute and have that perspective as well.
