Natural Science Quiz Questions and Answers

Kids have so many science questions! Delight their curiosity with these answers to top science questions kids ask. These simple answers are easy to understand, but tackle real science concepts to answer the how and why of our world. The atmosphere i. White light is made of several different colors, like you see in a rainbow. Red light has a long wavelength, while blue light has a much shorter wavelength. When light from the sun enters our atmosphere, the waves collide with gas molecules. Shorter wavelengths, like blue, bump into the gas molecules and scatter in different directions.

Some of it still makes it through directly, but the rest is reflected back to our eyes from all directions, so the whole sky looks blue. Use a slinky to demonstrate wave-length motion. The earth weighs 13,,,,,,,, pounds. You can say this number like this: 13 octillion, septillion. How do scientists know how much the earth weighs? They study the gravitational pull the earth has on other objects, and use math to calculate how big the earth must be. The sun is 93 million miles away from the earth.

Even light, which travels so quickly that we cannot even see it move, takes eight minutes to get from the sun to earth. In a jet traveling miles per hour, it would still take 19 years to reach the sun. In a car traveling 60 mph, it would take about years. Using the power of the sun, explore your creativity with a sun print paper kit for kids and adults.

A black hole is an area in space where matter what everything is made of has collapsed in on itself. A black hole has a strong gravitational pull that sucks in everything nearby — even light. Nothing can escape it. Should you be worried that a black hole will suck up the earth and the rest of our solar system? Definitely not. Many galaxies have black holes in them. A black hole is large enough to pull objects near it, but not those far away.

Even supermassive black holes will not continue to grow forever. Just as the black hole was born, it will one day die. A black hole will slowly evaporate, releasing the energy it took back into space.

Study the stars with an Orion reflector telescope. This force lifts up. If lift is more than weight, the plane will rise. If thrust is more than drag, the plane will gain speed.

Airplane wings are designed to take advantage of lift. They are shaped so that air has to travel farther over the top of the wing than underneath it. When the air has to travel farther over the top of the airplane wing, it must also travel faster, which results in lower pressure. The shorter distance under the wings results in higher pressure, causing the airplane to move upward. Explore the physics of flight by building a model airplane with the ultralight glider kit.

To unstick their feet so they can walk anywhere, the fly uses tiny foot claws to push or twist themselves away. Explore glues and polymers with a slime science kit for kids. The colors that make up white light are the same colors that make a rainbow. They are: red, orange, yellow, green, blue, indigo, and violet. You can often see a rainbow after it rains. Beams of sunlight shine towards the rain in the air and when the light goes into the raindrops, it is bent refracted.

When the light bends, it breaks into all of its colors. The colors of the rainbow always appear in the same order because each color always bends at the same angle. Learn more about colors, make your own simple rainbow, and make a prism with these sunny day activities: 3 Rainbow Science Projects. Bend and refract light with a glass prism. Perfect for hours of fun! No, sharks are not mammals.

Mammals, like polar bears, squirrels, lions, elephants, and dolphins, give birth to live young. They are warm-blooded, and have fur or hair. Sharks are a type of fish. They use gills to breathe. They also do not have bones like we do, but have a skeleton made of cartilage the same flexible material at the end of your nose. Another interesting thing about sharks is that some are oviparous they lay eggs , while others give birth to live young.

Study shark anatomy with a dogfish shark dissection. The moon is the brightest object in the night sky. During the day, the sun is much brighter! But sometimes, you can see the moon during the daytime. Why is this? The moon is always in the sky. It orbits travels in a circle around the earth. The sun always lights up half of the moon. But we cannot always see that part of the moon — sometimes it is facing away from us. Sometimes we see a full moon, big and round. Other times we see only part of the moon a crescent.

Learn more about the phases of the moon! Look for the moon in the sky today! If the moon is waning appearing smaller each night look for it in the morning, after sunrise. If the moon is waxing appearing bigger each night look for it in the late afternoon or evening, before sunset. Track the phases of the moon with weather forecast station. Many birds fly south in the winter. Birds that eat nectar or insects will not be able to find food in areas that have cold winters.

Birds that migrate usually leave at about the same time each year and fly back home at around the same time each spring! How do they know when to come back to their homes? Some kinds of birds might fly very long distances, like from Canada down to Central America, while other kinds of birds only fly across a few states.

It can take the flocks weeks or even months to get to their winter home in the south, depending on how far they have to go and how fast they fly. Explore the world of bird-watching with a golden guide birds book and Celestron 10 x 50 binoculars.

Explore force and motion with a physics lab experiment , make a DIY battery with our potato battery kit , study alternative energy with a solar power experiment , learn about acids-base reactions with a bath bomb science kit , observe the microscopic world around you with a home microscope , and explore your backyard with rockhound kits.

Why is the sky blue? How much does the earth weigh? To put things in perspective: One male African bush elephant weighs 13, pounds. One million elephants would weigh 13,,, 13 trillion pounds. One trillion elephants—there are not even this many on earth—would weigh 13,,,,, 13 quintillion pounds. And still, earth weighs one billion times more than that! How far away is the sun?

This is one of those science questions that boggle even the adult mind! What is a black hole? This means a lot of matter takes up only a tiny amount of space. How do airplanes fly? Even though airplanes are very heavy, they stay up in the sky. There are different forces pushes and pulls that make flight possible. How do flies walk on the ceiling? Flies can walk upside down!

They can do this because of their sticky feet. A fly has foot pads that are covered in tacky glue. How are rainbows made?
