Newton’s Rings Fun Facts

An interference pattern caused by the reflection of light between two surfaces, a spherical and an adjacent flat surface is known as Newton’s Rings. These patterns are formed by light incident on the thin film of air between the convex surface of a convex lens and a flat glass plate. These...

Wedges

Look at the edges of an axe. What do you see? If you said an inclined plane, you’d be on the right track. Wedges are similar to inclined planes, but there are some differences. An axe is actually two inclined planes put together. An...

Wheel and Axle

Wheel and Axle
Imagine a world with no wheels. No cars, no bicycles, no scooters, no skateboards, no roller skates. How would you get around? How would you bring things from one place to another? Your options would be to walk, use horses and other animals, use sleds, or go by boat. Not very convenient,...

Levers

Levers
Let’s say you have a tree house. You need to lift a large bag of snacks up to the tree house. How could you do it? Several simple machines might come in handy. You could make a simple pulley with a rope strung over a branch to lift the bag. But if you didn’t have a rope, you could use a...

Buoyancy

Buoyancy
King Hieron II of Syracuse asked the Greek scientist and mathematician, Archimedes to solve a problem for him. He suspected that a craftsman had made his crown out of silver and gold, rather than all gold as he had requested. He asked Archimedes to find out if the craftsman had cheated him by...

Density

Density
Let's say you have a brick and a piece of Styrofoam that are exactly the same size. Which one weighs more? Chances are, you said the brick weighs more but do you know why? It's all about density. Fun Facts The density of an object is determined by two things: the mass...

Velocity

Velocity
Your mom is driving your car at 30 mph. That’s her speed. She’s driving the car north to drop you off at school at 30 mph. That’s her velocity. Scientists call speed a SCALAR because it has only one attribute, magnitude or speed. Velocity is a vector. It has two attributes, magnitude...

Laws of Motion

Laws of Motion
Sir Isaac Newton, born in 1643, was one of the greatest scientists and mathematicians that ever lived. He was curious about the world and the universe and his discoveries paved the way for modern science and math. He developed the Three Laws of Motion, which explain how forces work to move...

Energy

Energy
Your body turns the cereal you ate for breakfast into energy. This energy allows you to run and play or learn at school. The fuel in your parents’ car is burned, creating energy that makes the car run. Energy is all around us and is simply the ability to do work. Fun...

Gravity

Gravity
What goes up must come down, but have you ever wondered why? The answer is gravity. Gravity is an invisible force that pulls one object toward another. Anything that has mass – including humans – has gravity. The more mass an object has, the stronger its gravitational pull. We can’t...

Friction

Friction
What would happen if you tried to slide across the cement in your tennis shoes? You probably wouldn’t move much and you might even trip, right? What if you tried to slide across a wooden floor wearing only socks? Or slide across a sheet of ice in your boots? You’d probably slide right along....

Simple Machines

Simple Machines
Let’s say you needed to lift something very heavy. How could you do it? Sure, you could ask a friend to help – or maybe even two or three friends. But what if the object was REALLY heavy? You might need some extra power, right? Simple machines increase force and

Gears

Gears
We don’t know who invented the first wheel, but we do know that it was one of our most important inventions. Wheels allow us to go places and allow products to be delivered to us. Gears are another important invention. Gears are wheels with teeth. They are simple machines that harness...

Parachutes

Parachutes
Have you ever watched a milkweed seed, a bit of cottonwood fluff, or a feather float through the air? We know that gravity is always present, pulling any object that goes up back down. Why do these objects seem to take a long time to reach the ground though? It’s not because they’re light,...

Electricity

Electricity
We know that atoms contain neutrons, which have no charge; protons, which have a positive charge; and electrons, which have a negative charge. Protons and neutrons stay within the atom, but electrons are a little like bumper cars. They race around and can even jump from one atom to another....

Color

Color
Think about the waves in the ocean. They seem to roll forward. Sometimes the waves are wide and slow. At other times, the waves seem close together and they move quickly. Light moves in waves too. Some of the waves seem to move slowly with wider spaces between them. Others move more quickly with...

Light

Light
Light is something that we take for granted. Turn on a switch and voila, light! In most cities, street lights shine throughout the night. A few hundred years ago, though, people really appreciated light. Once the sun went down, the only light they had came from candles, simple lanterns, or the...

Heat
Think about all the ways you can make heat. Put a log on a fire and it burns, creating heat. Run around the playground and your body gets warm. Turn up the thermostat on the furnace and warm air flows from the vents. Or, rub your hands together and you'll notice heat. Fun...

What is Physics

Physics is the study of all matter, energy, and forces and how they interact. Unlike chemistry, which focuses on combining atoms and elements into substances and compounds, physics explores mechanics, energy, momentum, waves, light, heat, sound, electricity, magnetism, optics, and...
