Wow! What a lesson plan! Six terrific activities are described in great detail, in this 31-page document! Learners will model and explain cloud formation, sketch and identify certain cloud types, calculate and compare incoming and outgoing radiation, and make climate predictions based on increases or decreases in certain cloud types. I can't say enough good things about this lesson. If you are a 5th - 8th grade science teacher, check this one out for sure!
