part 2: water cycle
scientists use models and diagrams to explain and better understand concepts in science. they can break down complex ideas into simpler ones or show how pieces come together to form a whole.

now it’s your turn. you have learned about the water cycle and the processes that occur. draw a diagram or create a model of the water cycle and submit it with the assignment. label the processes of the water cycle. if creating a model, take a picture and submit it with your assignment. use your model to answer the questions.
