Ideas about the EM spectrum have changed over time. In this activity, students will create a timeline that highlights how the EM spectrum developed over time. This will highlight how science needs scientists to collaboratively work together to share findings to further human understanding and how scientific discoveries can directly benefit the human race and lead to important inventions.
For an alternative to the timeline layout, have students create a timeline poster to incorporate into a presentation or gallery walk. You can add more than one template to this assignment to give students lots of options and adjust the instructions accordingly.
(These instructions are completely customizable. After clicking "Copy Activity", update the instructions on the Edit Tab of the assignment.)
