Through the theme of mechanical toys, students explore the concept of control systems, and use the Internet to research related concepts. Students conduct a hands-on class activity in which they take apart a mechanical toy and analyze the input, control, and output of the device. Then, they create a multimedia presentation to explain how the control system of the toy works. In this lesson students explore the technology of vertical architecture. They learn about planning, design, and construction-technology as it relates to tall buildings.
Students design and construct a solar cooker.
They use the Internet to research solar collectors and the process of changing light energy into heat energy. Using their research, students consider various uses and designs of solar collectors. The completed solar cooker is then tested by cooking a basic recipe at appropriate temperatures. Up, Up, and Away This activity allows students to investigate and apply the laws of physics that govern the flight of helicopters and airplanes. Students build and launch a model rotor, simulating rotors used on helicopters to provide lift.
