This lesson plan teaches students about the earth's structure. There is a section in which the teacher guides the students in comparing the earth's layers to those of a hard boiled egg, followed by a lego group activity for the students to create a cross section of the earth's layers. There is also a colored worksheet included, which serves as a useful form of independent practice after the group activity. I have also included a list of my resources and helpful books that might help students grasp the subject. Lastly, there is a useful YouTube video included which is a rap about earth's layers. My students LOVED it and were singing it for days!
