Introduction
Hello Scientists!
WONDER: What are the characteristics of mechanical and electromagnetic waves?
This is the question that you and your classmates will investigate in your role as student scientists.
Task
You will identify the characteristics of electromagnetic and mechanical waves
Process
INSTRUCTIONS:
1. Explore the virtual simulation . . .
https://phet.colorado.edu/sims/html/wave-on-a-string/latest/wave-on-a-string_en.html
- While you were interacting with the wave on the string, explain the relationship between amplitude and frequency. Were there any factors that affected the wave?
- Elaborate on what you explored during the virtual simulation. Minimum of 3 complete sentences.
2. Watch the video . . .
3. Investigate the presentation to learn more about energy ! ! !

- Name and define the two types of Waves.
- Examples: Sound waves, ocean waves, ripples in water, earthquakes, wave of people at a sporting event. If waves transfer energy, which type of mechanical wave do you think transferred the most energy? Why?
-Compare and Contrast the mechanical waves: Transverse vs Longitudinal Waves.
- Types of Waves:
1. sound Wave, ocean wave, stadium wave, wave on a rope - which does NOT belong. Why?
2. microwave, x-ray, laser, sound wave - which does not belong. Why?

Conclusion
Well Done Scientists ! ! !
You have shown that you understand the characteristics of electromagnetic and mechanical waves . . .
You have a task to do ! ! !
- Select 1 of the experiments found in the link. https://www.fizzicseducation.com.au/category/150-science-experiments/light-sound-experiments/
- You will record or provide an image of yourself performing the experiment.
- You will then write a one page reflection on your experience with the experiment.
Introduce your experiment.
