In this lesson, students learn about work as defined by physical science and see that work is made easier through the use of simple machines. Already encountering simple machines everyday, students will be alerted to their widespread uses in everyday life. This lesson serves as the starting point for the Simple Machines Unit.

In this lesson, students will be learning to convert Inches to centimeters and millimeters.

Students learn the metric units engineers use to measure mass, distance (or length) and volume. They make estimations using these units and compare their guesses with actual values. To introduce the concepts, the teacher needs access to a meter stick, a one-liter bottle, a glass container that measures milliliters and a gram scale.

I use this to help students memorize the information they need to know for making conversions.  Tools and charts are not always available so this will help students focus on the information that they should memorize so they could complete the conversions without using a tool or a chart.I spend time on the memorizing after much instruction and practice with the metric and customary units. So both metric and customary units are included in this memoriztion practice.

In this technical education lesson, students should be able to determine and use the correct size drill and tap to make a threaded internal thread.
