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?
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.

Select the answer choice that will not stick to a magnet.
Select the answer choice that will not stick to a magnet.
A magnet can stick to metals that are made of iron, cobalt, or nickel. A magnet cannot stick to plastic, wood, rubber, and many other non-metal objects.
Looking at our answer choices, a paperclip, nail, and nickel are all made out of metals that are magnetic. A stick is made of wood, which is not a magnetic material, so it will not stick to a magnet.

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.

How does light travel?
How does light travel?
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.

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 object would be the best for investigating light reflection? (Remember reflection means to throw back or send back)
What object would be the best for investigating light reflection? (Remember reflection means to throw back or send back)
The object that would be most appropriate for investigating light reflection would be a mirror. Mirrors reflect images and light, whereas paper and clothing absorb light. Using a mirror would allow someone to shine a light on the mirror and record how it reflects and study why.

Which object would be best to use in an investigation about blocking light?
Which object would be best to use in an investigation about blocking light?
A dark sweater would be the best object to use in an investigation about blocking light because it is made of a material and is a color that absorbs or blocks light. A glass cup and plastic wrap are clear, so the light will pass through, whereas a dark sweater will prevent the light from passing.

A light wave can be used to send messages.
This is a true statement. Light is used to communicate and send messages every day. Everyday crosswalk signs, lighthouses, traffic lights, and so many more help to send messages to people all around. Light is made of waves, and we can use these waves to keep people safe and pass information.

Which of the following objects provides evidence that humans can make light sources?
Which of the following objects provides evidence that humans can make light sources?
A flashlight is a human-made object, so this gives us evidence or proof that humans can make light sources. The Sun and lightning are both natural sources of light, so nature, not humans, created them.

The candles on the top illuminate this cake. From the picture, we can observe that the only source of light is coming from the candles, and without them, it would be dark. The background of the picture is dark, so there are no other sources of light.

Illumination is necessary to see objects in the dark. I tested this by looking into a dark room with no lights and a dark room with different light sources (candles, flashlights, and lanterns). When I used a light source, I could see what was in the room. When I did not use a light source, I could not see.

Tina took a flashlight with her and explored a dark cave. She couldn't see anything but heard strange noises. Once the cave was illuminated with the flashlight, she saw there were tons of snakes! The flashlight went out, and it was dark again. She ran towards the light at the entrance of the cave and went home.
Which two sentences provide evidence that a light source is needed to see in darkness?

Which two sentences provide evidence that a light source is needed to see in darkness?
The sentences that provide evidence of a light source are necessary are, "Once the cave was illuminated with the flashlight, she saw there were tons of snakes! The flashlight went out, and it was dark again.". These sentences explain that once the flashlight illuminated or light up the cave, she could see the snakes. It also states that it went dark again when the flashlight went out. This shows readers that the flashlight is where the light came from and was needed to see in the darkness.

Kelly wants to look for bugs that only come out at night. She looks around and finds an old lantern to bring with her. When she gets outside, it is so dark she can't even see her feet! She turns on the lantern and can see all the bugs crawling on the roots of a tree. She records what she sees and goes inside.

Which two sentences provide evidence that light is needed to see things in the dark?
Providing evidence is like giving proof of something or for something. In this short passage, two sentences show us how light is needed to illuminate and see objects in the dark. "When she gets outside, it is so dark she can't even see her feet! She turns on the lantern and can see all the bugs crawling on the roots of a tree." The first sentence lets us know it is dark, and she cannot see anything, not even her feet. In the second sentence, she illuminates the area around her with the lantern so she can see the bugs and roots. These sentences show that light is necessary to see.
