Set the Scene:
Let’s start with some questions to connect your everyday life to the subject of counterintuitive mechanisms. Have you ever experienced a situation where something didn’t behave as expected? Maybe you’ve seen a spring shrink when stretched or a traffic jam get worse when a new road is added. How do you think these phenomena can be explained? What are some examples of counterintuitive behavior you’ve observed in your daily life?
Featured Image Analysis & Prediction:
Look at the featured image and describe what you see. What do you think this activity will be about based on this image? Do you think it’s related to physics, engineering, or something else? Share your thoughts and predictions with your partner or the class.
Introduction:
Read the introduction to the activity and get an overview of what counterintuitive mechanisms are and how they can be observed in various systems, from mechanical to food chains and power grids.
Video Engagement:
Watch the video associated with the activity, available at https://www.youtube.com/watch?v=-QTkPfq7w1A. Pause the video at the following points and discuss the questions with your partner or the class:
- After the introduction to counterintuitive mechanisms, what are your thoughts on how these phenomena can be explained? Do you think they can be applied to real-world problems?
- When the video explains the counterintuitive behavior of springs, can you think of any everyday situations where this behavior might be observed? How can this knowledge be useful in engineering or physics?
- After the explanation of Braess’s paradox, discuss how this concept can be applied to traffic flow or network connectivity. Can you think of any examples where adding more roads or connections might actually increase congestion?
