One fun and easy way to remember the order of the different radiation types is by using this mnemonic: “Red monkeys in vans use x-ray glasses”. It's also fun when your students come up with their own! In this activity, students will create an EM Spectrum chart. They should include the uses and dangers of each type of radiation, and can create their own mnemonic. Students can use the chart they created as review, and this activity can be completed at the beginning or the end of a unit.
This activity can easily be differentiated and modified for your students by removing rows and deleting or adding information. Cut up the example chart and get your students to put it together like a jigsaw puzzle. Alternatively, have a student or small group complete a column each, then combine the columns to make a complete spectrum. You may also choose to have students write the wavelength and frequency ranges in the chart, although this can be difficult because often the different radiation parts overlap, and students may find that the numbers found for the ranges vary from website to website.
