Outcomes

In this lesson you will learn about:

1. Rounding off numbers.
2. Estimating answers to calculations.

This YouTube video explores the concepts of approximations and estimations.

The amount of effort saved when using machines is called mechanical advantage (MA). Simple machines use mechanical advantage as a key property to their functionality, helping humans perform tasks that would require more force than a person could produce. We will use the lever as an example of a simple machine to illustrate the concept of mechanical advantage.

Outcomes:

• Design a diet and exercise regimen.
• Estimate the number of calories required for basic survival.
• Estimate the number of calories burned by exercise.
• Explain how heart health depends on diet and exercise.
• Explain how Body Mass Index (BMI) depends on weight and height.

In this unit you will learn how to identify equivalent metric units of capacity.

In this online course, you will learn how to identify equivalent metric units of mass.

In this unit we will learn how these factors can affect the output of a simple machine. We will also learn about the difference between ideal mechanical advantage (IMA) and actual mechanical advantage (AMA), and how to apply your knowledge to calculate the efficiency of various simple machines.

In this online lesson you will learn how to compare measurements that have different units.

In this unit you will learn how to convert between common metric units of measure.
