Good afternoon!

In a lesson plan for science about the planets and the Earth I see really necesary to use images that help the students to visulize the concepts and to understand topics that are not visible for the human eye.

In this case, it is more visual for children to study the planets if they see them, and recognize their colours and size. Because of that, these are some of the pictures I would use in this lesson plan explain this topic:
