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.

There are some key words that you need to know for circles: radius, circumference, diameter, sector, segment, tangent, chord and arc. In this video you will discover what they all mean.

This video discusses the topic of circles.

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.

When electromagnetic radiation is absorbed by a material the energy it carries has to go somewhere. When lower energy waves, like radio and infrared waves, are absorbed there can be an increase in temperature of the absorbing material. Higher energy waves, like x-ray and gamma waves, can actually permanently damage or change materials. Learn about the different types of electromagnetic waves and how their energies can influence their effects on objects.

This video explains the equation of a circle.
