Step 1. Questions
Put two or more simple machines together, and you have a compound machine. Even the most complex machines are examples. Look at the parts of a car, for example, and you will find levers, wheels and axles, and pulleys. When simple machines are put together the right way, they can do all sorts of things!
For this e-Journal project, you will choose at least one interesting compound machine and learn how it works. Here are some questions to guide your research.
Are you ready? Begin by researching the compound machine of your choice. You may choose from those listed in the Web links, which are found in Step 2. Or use search engines to find other compound machines. When you are ready, follow Steps 3 and 4 to write your report.
