We can apply the law of reflection and some concepts in geometry to measure the height of an object that would be very difficult to measure directly.
I hope you enjoy doing this activity.
In the diagram below, "h" is the height of the person's eyes above the surface of the water, and "d" is the horizontal distance from the person to the center of the bowl. "H" represents the height of the flagpole, and "D" is the horizontal distance from the flagpole to the bowl of water. The 3 distances h, d, and D are easy to measure.
Congratulations to the groups that got the closest to the actual height of the pole. More exciting activities to come...
