1. Create your own Electromagnetic Spectrum!
Use the supplies at your desk.
Fold the construction paper like this   
Label the top of your construction paper “ The Electromagnetic spectrum”
The top line will be where the crests of your waves reach.
The bottom line will be where the troughs of your waves reach.
Make your electromagnetic spectrum begin with long wavelengths/low frequency waves and end with short wavelength/high frequency waves.
Draw an arrow showing how frequency increases along your EM spectrum.
Draw an arrow showing how wavelength increases along your EM spectrum.
Label the types of waves that are found along the spectrum, draw a picture that describe each of those wave types.
