How can you measure the speed of an object
Measure the time the object takes to travel a specific distance
Why Is The Sky Blue
Gases and particles in Earth's atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves
Sharks Are Not Mammals. As you can see, sharks don't fit the criteria for mammals in the most important respects.

A black hole is a place in space where gravity pulls so much that even light can not get out.
How are rainbows made?
When sunlight hits a rain droplet, some of the light is reflected.
Offspring resemble their parents because they inherit genes instructions for biochemical, physical, and behavioral traits, some of which are responsible for diseases from their parents
The concept of gravity was discovered by which famous physicist?
Sir Isaac Newton contributed several key principles to the studies of science and mathematics in the fields of optics, calculus, and mechanics.
how can we hear music
sound waves traveling in to one of our senses
How do airplanes fly?
Airplanes fly because they are able to generate a force called Lift which normally moves the airplane upward.
How far away is the sun?
As noted earlier, Earth's average distance to the Sun is about 93 million miles (150 million kilometers) from the Sun. That's 1 AU.
Why do we dream?
One widely held theory about the purpose of dreams is that they help you store important memories and things you've learned, get rid of unimportant memories, and sort through complicated thoughts and feelings.
Humans and chimpanzees share roughly how much DNA
These three species look alike in many ways, both in body and behavior
how does it rain
Clouds are made of water droplets. Within a cloud, water droplets condense onto one another, causing the droplets to grow.
How do flies walk on the ceiling?
Flies need sticky feet to walk on ceilings, but not so sticky that they get stuck upside down. So each foot comes with a pair of claws that help hoist the gooey foot off the wall.
How did life begin?
After things cooled down, simple organic molecules began to form under the blanket of hydrogen.
Are there other universes?
There is not one universe—there is a multiverse.
Which is the main gas that makes up the Earth's atmosphere?
Earth's atmosphere is composed of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases.
How does lighting form
Lightning begins as static charges in a rain cloud. Winds inside the cloud are very turbulent.
