Activity Overview
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.

Student Instructions
Create a visual timeline of how and why ideas of the EM spectrum have changed over time.
- Click "Start Assignment".
- Choose six people or moments in the history of science that you think are the most important in our understanding of the EM spectrum.
- Write a title and the date (just the year is fine) for these six moments using the timeline.
- Illustrate the moment with a cell using a combination of scenes, characters, and items.

How Tos about Electromagnetic Spectrum Timeline
Incorporate primary sources to deepen timeline research
Enhance your students' understanding by guiding them to find and use primary source materials, such as scientists' original diagrams or letters, for each timeline event. This exposes learners to authentic historical context and helps them practice critical analysis skills.
Model how to locate reliable science history sources online
Show students step-by-step how to use trusted websites, academic databases, and digital archives. Point out key features like .edu, .gov, and museum sites to reinforce the value of credible information.
Guide students to analyze and summarize primary source content
Help learners break down complex language from original documents by highlighting the main idea, key discoveries, and historical impact in their own words. This improves comprehension and communication skills.
Encourage creative integration into timeline visuals
Invite students to embed excerpts, images, or quotes from primary sources directly into their timeline cells. This makes their work both informative and visually engaging, fostering deeper connections with the scientific process.
Facilitate classroom sharing and discussion of discoveries
Organize a gallery walk or presentation session where students explain the significance of their chosen primary sources and how they shaped our understanding of the EM spectrum. This promotes speaking skills and collaborative learning.
