Structure and Composition of the Earth
Subject area: Science
Grade level: Third
Time needed: 45 minutes to 1 hour
Standard: Earth and Space Science: Understands basic features of the Earth
Materials: overhead projector, Vis-a-Vis markers (several colors), overhead transparency, modeling clay or Play dough (yellow, green, blue, red), toothpicks, index cards (cut into 1 inch squares), tape, construction paper, magic markers, plastic knives
Differentiation: Students will have the opportunity to work with a partner if they would like to. The teacher can write the labels for students who have a hard time copying work off of the board.
Technology link: This first part of this activity could also be used with a Smart Board instead of an overhead projector. Students could move the labels around on the graphics on the Smart Board. Students can also look at two websites for pictures and graphics about the layers of the Earth and other geological formations for later studies: www.pbs.org/wnet/savageearth/animations/hellscrust/main.html or www2.nature.nps.gov/geology/tour
Assessment: The teacher will assess students’ work by checking to see if the labels go with the correct layer. The assessment will be done by observation.
Cross Curricular Connection: The teacher could read The Magic School Bus: Inside the Earth to the students as an introduction or follow up to the lesson.
