What color makes up all the other colors?
What is white?

A distant hillside has green grass. Why does the grass look green?
What is the color green is being reflected from the grass into your eyes and all the other colors are being absorbed.

What color is most likely going to absorb the most sunlight and heat up?
What is black or dark blue?

What is the light transfer when light rays are bent due to changes in the speed of the light from one medium to another medium?
What is refraction?

How does light travel? What experiment could you try with index cards, scissors, and a laser/flashlight to prove that this is true?
What is light travels in straight line waves. I could use the index cards by cutting a hole in the center of the card and lining up all the cards. I would use the laser to shine light through the holes and see if I can get the light to pass through all three cards.

What is the area behind the object called where the light can not pass through the object?
What is a shadow?

In the world sometimes, objects reflect light. Give me 3 objects that reflect light. They can be here on Earth or not.
What is Apple, Bookbag, Walls in the Room, Moon.

What does black or dark colors do? What does white and light colors do when you are wearing them?
What is black with absorb all the colors of light and heat you up? What is white will reflect all the colors of light and keep you cool?

What does the prism do to the white light that shines into it?
What is refracts or separates the white light into all the colors of the spectrum (ROY G BIV).
300
What are all the colors of light in the spectrum in order?
What is ROY G BIV - red, orange, yellow, green, blue, indigo, and violet?

What is the material called that light and sound can travel through? Examples are air, water, glass, plastic, corn syrup, and vegetable oil.
What is a medium?

If there are people and swans swimming in the pond, will there be a reflection when another person looks in close to the people and swan? why?
What is No - there will be no reflection because the water looks rough and wavy causing light to scatter and not come in and out at the same angle.
300
What degree of light will heat up an object quicker? 80 degrees or 20 degrees? Why?
What is 80 degrees because the light angle is close to 90 degrees which is straight up and down. It will be more direct on the object like wood or metal.
300
What happens when you pass a pencil into a cup of water? Why is this happening?
What is the pencil looks like it is bent? It is being refracted. The reason this is happening is because light is faster in air and is having to slow down when it reaches the water making it play tricks on your eyes.

What objects emit light? Give me 3.
What is fireflies (lightning bugs), fire, sun, stars, flashlight, and light bulb?

Why is there smoke at a dance party that has a disco ball in the center of the room on the ceiling?
What is the light must need something to reflect off of to see the light through the air?
400
When light hits a rough surface like the stucco walls in the classroom, what will happen to the light?
What is the light will reflect back in different directions and scatter? The light will not leave at the same angle it came in.
400
Light can produce ______________.
What is light can produce heat?
400
Do lens reflect or refract light? Explain why you picked refract or reflect.
What is lens refract light. The lens are shaped differently and not flat so it will bend light inwards or outwards to a certain point to make the object bigger or smaller depending on what type of lens.

A thunderstorm is a good example when trying to explain whether light or sound is faster. Why? Which one is faster, light or sound?
What is in a thunderstorm, you will see the lightning first and then hear the thunder a few seconds after. Light is faster and sound is the slowest to move.
500
In what substance (air, water, or glass) does light move the fastest in? Talk to me about the particles.
What is light moves the fastest in air because the particles are more spread out letting light move through faster. A solid has particles close together and will not allow light to pass through therefore solids are most times opaque.
500
What are the three things that make light reflect perfectly? How must the object be? Describe it.
What is the object must be shiny, have a smooth surface, and be made up of the color white because white normally reflects all colors of light.
500
Give me 2 things that could influence the temperature of an object.
What is the material of the object, how long time wise you keep the light on it, the angle of the light on the object (directly or indirectly), the color, or how well the object absorbs.
500
What does convex lens do to the object?
What is the lens makes the objects appear bigger in size?
