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

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

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

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

What makes a shadow?
What makes a shadow?
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.

Which list of objects allows light to pass through them?
Which list of objects allows light to pass through them?
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?
What can Mel conclude about how light affects different objects based on the data above?
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.

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

Which item would be best for covering blocking light?
Which item would be best for covering blocking light?
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.
