Constructing a simple magnifier engages children with embodied cognition, as they create a tool that interacts with light. This hands-on experience solidifies their understanding of optical principles through direct observation and manipulation.
1. Take a clear plastic bottle and cut off the bottom. 2. Fill the bottle with water until it's half full. 3. Find a small object or text to examine closely. 4. Hold the bottle over the object and adjust the distance until it's magnified. 5. Observe how the details change as you move the bottle closer or further away. 6. Share your findings with a family member — what surprised you?
