Project Overview

Read This First |
Students in partnered classes will design a device that incorporates three simple machines. The job of this device will be to move and deposit a ping-pong ball into a drinking cup. In the course of traveling from point A to point B (the cup), the ping-pong ball must move a minimum of one meter in a horizontal direction and thirty centimeters vertically. Materials used to create the contraptions will be common classroom items and supplies. Students will be encouraged to use any RECYCLED materials that they bring from home that can be SAFELY used in a classroom setting. Some examples of materials are: paper clips, cardboard tubes, string, rubber bands, erasers, tennis balls, rulers, old bicycle parts or broken household tools and appliances. Students will write a paragraph describing how their device works, describing each machine used, and the movement of the ping-pong ball through the device. This descriptive paragraph will be posted to the partnering class. The partnering classes will work to visualize or replicate (SIGHT UNSEEN) the contraption based on the descriptive paragraph. Exchanges between the partnering classes can be done via e-mail (preferably) or snail mail (if necessary). As a final activity, partnering classes will view pictures of each other's device. Pre-Activities are provided to teach students about Simple Machines and the development of Complex Machines. A variety of extension activities are also provided. The project is designed to be implemented over a four to six week period and is appropriate for Grades 4 - 8. Resources, reproducibles, and bilingual translations (Spanish) are included.
