Academic Enrichment Theme – Simple Machines Overview Students will learn about what a simple machine is and study the six different kinds of simple machines: inclined plane, lever, pulley, screw, wedge, and wheel and axle. This unit is book based, with books available from the Howard County Public Library and also involves student experiments and a collection of simple machines. Students will complete a page in a workbook for each type of simple machine. You could culminate this theme with a Rube Goldberg challenge (the public library sponsors one every year) where students have to use simple machines to complete a task. Here’s what the library website has to say about the challenge: The Rube Goldberg Challenge unleashes the creativity of fourth and fifth grade students as they apply STEM concepts to solve a problem.

General Bibliography Each simple machine has a separate bibliography, but here are three books that give an overview of all the machines and provide additional experiments. Thompson, Gare. Lever, Screw, and Inclined Plane: the Power of Simple Machines. Washington, D.C.: National Geographic Society, 2006. Tocci, Salvatore. Experiments with Simple Machines. New York: Children’s Press, 2003. Van Cleave, Janice. Janice VanCleave’s Machines: Mind-boggling Experiments You Can Turn Into Science Fair Projects. New York: John Wiley & Sons, 1993. Session – What is Work? What is a Simple Machine? In this session, students will learn the scientific definition of work that will be used throughout all the sessions. They will also sort a variety of simple machines learning the six categories that will be studied in further sessions. The book by Thompson, Lever, Screw, and Inclined Plane: the Power of Simple Machines, has a great explanation for work that can be repeated with students (page 7). Have students push against an immovable object (wall or really heavy piece of furniture – make sure that it can’t be moved). Have them push as hard as they can. Then ask students to push a chair around them room. Tell them that scientists would only think of one of these activities as work – ask them to guess which one (pushing the wall or pushing the chair). Then tell them that scientists define work as a forced used to move an object over a distance. So, pushing against the wall wasn’t work to a scientist because the wall didn’t move. Students will define work in their workbooks. The book by Tocci, Experiments with Simple Machines, does a great introduction on simple machines and Rube Goldberg (pages 4 – 10). After reading the pages, pass out an assortment of machines to students and see if they can sort them into groups. The next two pages have a variety of simple machines sorted out by type. Try not to pass out the machines already in their groups. Have students share the groups that they made at their tables – you will have a variety of sorting methods. Define simple machine – a device that makes work easier to do and have students copy the definition into their workbooks. Provide simple categories and sort the machines with students – doing an example for each one and then seeing if they can find other examples that fit in the category. Students will draw the simple machine that they had during the sorting activity and label what kind of machine it is. Save the machines in sorted groups for the next six sessions.
