Students will draw a scale model of Earth.
Earth is a remarkably round, smooth object when viewed from space. It is important that students understand that from their view of Earth, it is bumpy but from space, it is quite smooth. A picture of Earth taken from space is helpful to have to point this out to them. Make sure students understand that the layers of Earth are NOT visible from space. You might also discuss the reasons scientists use models (for things to small, too large, too dangerous or that occurred in the past) to study and test. Remind them that no one has ever drilled into Earth past the Core although it has been attempted. Temperatures, pressures and difficulty with the drilling process currently make it very difficult to drill very far into Earth.
