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.

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.

Construct an evidence-based claim to answer the question below.
What illuminates this birthday cake?
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.

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.

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?
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?
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?
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.

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.

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.

Nancy cannot find her favorite shoes in the back of her dark closet. She grabs a flashlight and sees them! Why couldn't she find them before she turned on the flashlight?
Nancy cannot find her favorite shoes in the back of her dark closet. She grabs a flashlight and sees them! Why couldn't she find them before she turned on the flashlight?
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.

The word illuminate means to light something up. Humans have good vision, but we do not see well at night because there is limited light. Our eyes rely on light to reflect off the surface of an object so that we can see.

Which choice would be the BEST to illuminate a dark room?
Which choice would be the BEST to illuminate a dark room?
The best choice to illuminate (or light up) a dark room would be a lantern. A radio would give off little to no light, and a small candle would only produce enough light to see a few inches ahead of you. A lantern would give off much more light and help you to see in the dark.

Which object makes its own light?
A glow stick produces its own light. You can use a glow stick to illuminate a small dark area or to make yourself more easily seen at night time. Glow sticks make their own light when two chemicals are mixed after snapping or shaking the stick.
