How do we communicate with each other? How do we communicate with people who are close by? How do we communicate with people who are far away? In this lesson, students will explore the role of communications and how satellites help people communicate with others far away and in remote areas with nothing around (i.e., no obvious telecommunications equipment). Students will learn about how engineers design satellites to benefit life on Earth. This lesson also introduces the theme of the rockets curricular unit.

In this lesson, students are introduced to both potential energy and kinetic energy as forms of mechanical energy. A hands-on activity demonstrates how potential energy can change into kinetic energy by swinging a pendulum, illustrating the concept of conservation of energy. Students calculate the potential energy of the pendulum and predict how fast it will travel knowing that the potential energy will convert into kinetic energy. They verify their predictions by measuring the speed of the pendulum.
