Hole in the Bucket Questioning
This questioning would take place after the students saw the demonstration.
Q: What happened when you pointed the laser pointer into the hole in the bottle?
A: “the light went through the hole and followed the water down.”
Q: How does this compare to what happened when we used a flashlight?
A: “the light just spread out in all directions.”
Q: How would the behavior of a laser light be useful in the real world?
A: “they could use it to direct the light exactly where they want it to go like for medical purposes.”
Q: What if you don’t have a fluid involved, how else could you get the light to bend?
A: “use mirrors to direct the light.”
Q: Why would this work?
A: “because mirrors reflect light, you just have to move the mirrors at the right angle to get the light to move where you want it to go.”
