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?
Tap to reveal answer
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.

Tap to reveal answer
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 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)
Tap to reveal answer
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.

Tap to reveal answer
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.
Tap to reveal answer
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?
Tap to reveal answer
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.
Is this statement evidence-based, or is it an opinion? How do you know?

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?

Tap to reveal answer
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.

Tap to reveal answer
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.

Andrew was trying to look down the end of a very long sidewalk to see if his friend was coming, but it was too dark to see. He ran back home and looked for something to bring with him to help him see. Which item should he grab and why?

Tap to reveal answer
Andrew should choose the flashlight if he wants to get an item to help him see. A lightbulb will not work without electricity, so holding it up outside will do nothing. A candle will give off light to reflect off objects but only for a short distance, and he is on the end of a very long sidewalk. A flashlight would help him see the long-distance that is needed. It will reflect light off of the objects in the dark so he can see what is around him and if his friend is coming.

Which statement best explains why fireworks help us to see at night?
Which statement best explains why fireworks help us to see at night?
Tap to reveal answer
Humans can only see objects when they are illuminated by something that gives off or produces light. Fireworks do both of these things, so they help to light up the night sky and other objects around them. While waiting for a firework show, you may notice it is dark and hard to see the people around you; when the fireworks explode, you can see the people around you more clearly.

The best object to bring into a cave would be the fire torch. This would illuminate or light up the area around you so that hidden objects (or dangers) would be visible. In the dark, without any light source, we would not know what is up ahead.

To see objects in the dark, I must use a light source to illuminate it. I know this because I performed a set of investigations and collected data. The data showed that when I went into a dark room, and my brother held up a toy, I could not see what it was. When I used a flashlight, I could see the toy.

Tap to reveal answer
Nancy could not see her shoes in the dark closet because humans cannot see when there is no light. The light must shine on an object and reflect into our eyes for us to see the object clearly, or it must make its own light. Shoes cannot make their own light, and the back of the closet was too dark for her to see.
