13. Describe what is happening to the light in the picture.
The light is hitting the water and then being refracted (bent) so it looks like the spoon is broken or separated.

12. Reflection best occurs when light strikes what type of surface? 14. Does water ever behave like a mirror? Explain.
12. Shiny or glossy surface 14. Water will act like a mirror and reflect light if it is smooth, still, and clear.

11. If you were to design a classroom experiment to demonstrate refraction, what tools would you need? Explain how you would use them.
Tools- Laster pointer and a prism Explanation- I would shine laser through prism to show light bending

10. If you were to design a classroom experiment to demonstrate reflection, what tools would you need? Explain how you would use them.
Tools- Mirror, Laser Pointer, Target Explanation - I would shine laser pointer to reflect through mirror and hit target
