Example Questions

Example Question #1 : Investigate The Effect Of A Beam Of Light On Different Objects

What would happen if you put a mirror in front of a laser light?

Possible Answers:

The light would pass through

The light would be reflected

The light would be blocked

Correct answer:

The light would be reflected

Explanation:

When a mirror is placed in front of a light source, it will reflect the light or cause it to be bounced back. If I were to shine a laser light on a mirror in front of me, the light would be reflected and appear on the wall behind me. Other objects may cause light to be blocked or will allow it to pass through, but a mirror will reflect it.

Example Question #2 : Investigate The Effect Of A Beam Of Light On Different Objects

What would happen if you put a piece of plastic wrap in front of a flashlight?

 

Possible Answers:

The light would be blocked

The light would pass through

The light would be reflected

Correct answer:

The light would pass through

Explanation:

If you put a piece of plastic wrap in front of a flashlight, there would be little change because the light would pass through. Plastic wrap is transparent and allows light to be seen through the other side. Other objects may block or reflect light, but something clear would allow it to pass.

Example Question #3 : Investigate The Effect Of A Beam Of Light On Different Objects

What would happen if you put a sheet of black construction paper in front of a flashlight?

 

Possible Answers:

It would allow the light to pass through

It would reflect the light

It would block the light

Correct answer:

It would block the light

Explanation:

If you tried to shine a flashlight through a sheet of black construction paper, it would block the light. Light would not be able to pass through to the other side, and it would not be reflected. Something dark in color and also a thicker material like construction paper would block light from passing.

Example Question #4 : Investigate The Effect Of A Beam Of Light On Different Objects

If I place a chocolate bar in a beam of light from the Sun, what would the result be?

Possible Answers:

Nothing would happen.

It would melt.

It would freeze.

Correct answer:

It would melt.

Explanation:

If I were to place the chocolate bar in the Sun, it would melt due to the heat. The rays of light from the Sun are not only bright but hot. Chocolate is something that melts, and sitting under warm light would cause that to happen.

Example Question #5 : Investigate The Effect Of A Beam Of Light On Different Objects

What makes a shadow?

Possible Answers:

Shadows are made by bright lights mixing with dim lights.

Shadows are made by cold air and warm air mixing.

Shadows are made by blocking light.

Correct answer:

Shadows are made by blocking light.

Explanation:

A shadow is created by blocking light. Shadows need a light source like a lamp, the Sun, or a flashlight and an object to block the light. A simple way to see a shadow is standing outside during the day and looking down! Your body blocking the sunlight will create a shadow of your figure on the ground. Another easy way to make a shadow is by putting your hands in front of a flashlight in a dark room.

Example Question #6 : Investigate The Effect Of A Beam Of Light On Different Objects

How does light travel?

Possible Answers:

Light travels in waves and a straight line.

Light travels through sections or air in an S-shape.

Light travels in cars and trucks.

Correct answer:

Light travels in waves and a straight line.

Explanation:

Light travels in waves outwards from its source. Light travels in a straight line. It can be altered when it is absorbed, refracted, or reflected.

Example Question #7 : Investigate The Effect Of A Beam Of Light On Different Objects

Which list of objects allows light to pass through them?

Possible Answers:

Glasses, windows, and plastic wrap.

Walls, windows, and umbrellas.

Glasses, hats, and sunscreen.

Correct answer:

Glasses, windows, and plastic wrap.

Explanation:

The list of objects that allows light to pass them all has one thing in common; they are transparent (clear). Clear items will enable the light to move without being blocked or absorbed. Sunscreen, walls, hats, and umbrellas all block light from passing through.

What can Mel conclude about how light affects different objects based on the data above?

Possible Answers:

Light can either pass through an object or be stopped entirely. There is no in-between.

Some objects stop all light; some allow it all to pass through; others stop some light.

All objects are affected the same by light. There is no difference between different objects or materials.

Correct answer:

Some objects stop all light; some allow it all to pass through; others stop some light.

Explanation:

Based on the data given can conclude that some materials are transparent and let all light pass through. Some materials stop some light from passing through. Some materials are solid and block or reflect all light. A beam of light will have a different effect on an object based on that object's characteristics.

Example Question #9 : Investigate The Effect Of A Beam Of Light On Different Objects

Which item would be the worst for blocking light based on the data below?

Screen shot 2020 06 01 at 2.11.16 pm

Possible Answers:

Glasses

Vegetable oil

Shoe

Correct answer:

Glasses

Explanation:

The worst item for blocking all light would be the glasses. Glasses allow all light to pass through unless they are coated or tinted like sunglasses to block light. A much better item to block light would be a show because it is made of a dense, solid material that does not allow light to pass.

Example Question #10 : Investigate The Effect Of A Beam Of Light On Different Objects

Which item would be best for covering blocking light?

Screen shot 2020 06 01 at 2.23.06 pm

Possible Answers:

Cardboard

Wax paper

Mirror

Correct answer:

Cardboard

Explanation:

The best item for blocking light would be the cardboard. Cardboard is a thick, dark material that would not allow light to pass through or be reflected. Cardboard is used for packaging because it not only hides what is inside and is sturdy, but it keeps light from damaging the items inside.
