Example Question #9 : Relate The Amount Of Daylight To The Time Of Year

What does the term daylight mean?

Possible Answers:

Natural light from the stars

Natural light from the Sun

Natural light from the Moon

Correct answer:

Natural light from the Sun

Explanation:

Daylight means the arrival of natural light from the Sun. When the Sun rises in the morning, it shines a light on Earth, which we call daytime. The amount of daylight that we receive depends on the season.

Correct answer:

June; summer

Explanation:

The month with the most daylight is in June. This month is during the summertime. The longest day of the year is actually in June, and some places receive 21 hours of sunlight that day!

Example Question #41 : Earth And Space Science

Winter is the warmest season and has the most sunlight.

Possible Answers:

True

False

Correct answer:

False

Explanation:

This is a false statement. Winter is typically the coldest month and receives the least sunlight because of the Earth's tilt and location in its revolution. Summer is the warmest season and gets the most sunlight.

Example Question #1 : Physical Science

Which of the following objects provides evidence that humans can make light sources?

Possible Answers:

Flashlight

The Sun

Lightning

Correct answer:

Flashlight

Explanation:

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.

Example Question #2 : Physical Science

Construct an evidence-based claim to answer the question below.

What illuminates this birthday cake?

Birthday, Birthday Cake, Cake, Candles

Possible Answers:

Light from a lamp illuminates this birthday cake because a lamp is a light source. The light is coming from above, so it is from a lamp. I can tell the lamp is the only light source.

Candles illuminate this birthday cake because they are a light source. Without the candles, you could not see the cake. I can tell the candles are the only light source.

This cake is not illuminated. If it were illuminated, it would not be able to be seen. I can tell because illuminate means to be in darkness.

Correct answer:

Candles illuminate this birthday cake because they are a light source. Without the candles, you could not see the cake. I can tell the candles are the only light source.

Explanation:

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.

Example Question #1 : Illumination Of Objects In Darkness

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?

Possible Answers:

Tina took a flashlight with her and explored a dark cave. She couldn't see anything but heard strange noises.

She couldn't see anything but heard strange noises. Once the cave was illuminated with the flashlight, she saw there were tons of snakes!

Once the cave was illuminated with the flashlight, she saw there were tons of snakes! The flashlight went out, and it was dark again.

Correct answer:

Once the cave was illuminated with the flashlight, she saw there were tons of snakes! The flashlight went out, and it was dark again.

Explanation:

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.

Example Question #1 : Illumination Of Objects In 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?

Possible Answers:

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.

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.

Kelly wants to look for bugs that only come out at night. She looks around and finds an old lantern to bring with her.

Correct answer:

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.

Explanation:

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.

Example Question #5 : Physical Science

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?

Possible Answers:

Candle; it illuminates objects (and people) in the dark, so it will help him see a short distance

Flashlight; it illuminates objects (and people) in the dark, so it will help him see a long distance

Lightbulb; it illuminates rooms in a house so it should help him see in the dark outside

Correct answer:

Flashlight; it illuminates objects (and people) in the dark, so it will help him see a long distance

Explanation:

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.

Example Question #6 : Physical Science

Which statement best explains why fireworks help us to see at night?

New Year'S Eve, Fireworks, Beacon

Possible Answers:

Fireworks help us see at night because they are a source of light. They illuminate the sky and other objects.

Fireworks help us see at night because they absorb light from other things.

Fireworks help us see at night because they are beautiful and colorful. Things that are pretty are easy to see.

Correct answer:

Fireworks help us see at night because they are a source of light. They illuminate the sky and other objects.

Explanation:

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.

Example Question #1 : Illumination Of Objects In Darkness

I am only able to see in the dark when I have a light to help me. I can use a flashlight, candle, or turn on a lightbulb.

Possible Answers:

False

True

Correct answer:

True

Explanation:

This is a true statement. Humans have limited vision in the darkness; we need a light to help us. All of the items listed would be helpful in the dark. This claim is based in fact.
