What do you notice about the chopstick on the previous page?
Slide 3 - Open question
Try this at home with some other things like a spoon or fork. Describe your observation and place a photo in your answers.

Write down which tool(s) will help you to investigate the behavior of light.
Describe the behavior of light when it shines on water. Provide examples for a variety of incident angles to support your description.
Slide 7 - Open question
What changes if the light is underwater and the light goes into air? What changes if you shine light on glass?
Slide 8 - Open question
Test materials with other indexes of refraction to see if your ideas about the behavior of light seem comprehensive. Write a summary description of what happens to light when it goes from one medium to another. Use the following vocabulary words in your summary: index of refraction, incident angle, reflected angle, and refracted angle.

The difference in refraction angles is small and difficult to detect in this simulation, so I have shown a possible experimental setup for you to try. How much does the angle of refraction change from 380nm to 700nm when the angle of incident is 80?
Slide 12 - Open question
Run some of your own experiments to see if you can detect a difference in refracted angles at other incident angles. Why did I choose 80 degrees?
Slide 13 - Open question
Use the Speed tool as you vary the wavelength to help understand why the angle of refraction varies. Describe the results of your experiments
Slide 14 - Open question
Does the speed of the light colour change during refraction or reflection?
A
YES
B
NO

Experiment to find ways to make rainbows. Insert at least one setup where light passing through a prism gives a rainbow and describe why a rainbow is formed. Explain why only some types of light will yield rainbows.
