Heat: Math Lesson

Wrap-up

The electromagnetic (EM) spectrum shows different types of wave energy, from gamma rays to radio waves.  Think about the spectrum the next time you use a microwave, talk on your cell, or lie on a beach soaking up the sun.

In this lesson you:

• Learned the definitions of wavelength and frequency
• Examined the relationship between wavelength and frequency
• Used exponents to represent very large and very small numbers

On your own:

• Find examples in your own life of direct and inverse relationships.  For example: the more TV you watch, the more/less_______ (e.g. the more junk food you inadvertently eat?).  The less sleep you get, the more/less________.   The more time your kids spend on homework, the more/less___________.
• Find out the meaning of AM and FM radio. It’s all about the waves!
• Practice calculating exponents using a variety of bases and powers, including negative exponents.
• Get a ruler that measures both inches and centimeters.  Practice taking measurements with each system.
