Hey there! Have you ever wondered how big cities, fast cars, and even trips to the moon all started? It all began with simple things, like small towns, the first motor wagon, and the invention of the wheel. Today, we’re going to explore something super cool: simple machines!
Simple machines are tools that help us do work more easily. They have very few moving parts but can do amazing things. Let’s meet some of these helpful friends: the inclined plane, the lever, the wedge, the screw, the wheel and axle, and the pulley. These simple machines make our work easier and save us energy.
An inclined plane is like a ramp. It helps us move heavy things from a lower place to a higher place. Imagine a big dump truck weighing 1,256,000 pounds! An inclined plane helps it move up easily. Ramps are also used to help people in wheelchairs get over curbs or into buildings.
The wheel and axle are everywhere! They help us move things easily. Think about bicycles, cars, and even pottery wheels. Without wheels, moving things would be much harder. Imagine riding a bike with square wheels—how funny would that be?
A lever is a simple machine that helps us lift or move things. It works with a pivot point called a fulcrum. Examples of levers include scissors, pliers, and even your arm! A teeter-totter is a fun example of a lever in action.
The wedge is a powerful simple machine. It helps us cut or split things. Think about how a wedge can split wood or how a knife cuts through food. Even a nail is a tiny wedge that helps hold things together.
The screw is a simple machine that helps us hold things together. It can also drill holes or seal bottles. A spiral staircase is a fun example of a screw in action!
A pulley is like a wheel with a groove. It helps us lift heavy things with less effort. Pulleys are used in cranes to build tall buildings and in elevators to take us up and down floors. Who doesn’t love a fun elevator ride?
Now you know about the six simple machines: the inclined plane, the wheel and axle, the lever, the screw, the wedge, and the pulley. These machines are all around us, making our lives easier every day.
When we put simple machines together, we can create amazing things like cars, airplanes, and roller coasters. Even a bicycle uses many simple machines. Can you spot the wheel, lever, and pulley on a bike?
Your task is to look around and find simple machines in your world. They’re everywhere! And if you want more fun activities, check out Clarendon Learning for more exciting lessons.
Thanks for exploring simple machines with us! Keep learning and having fun!
Simple Machine Scavenger Hunt: Go on a scavenger hunt around your home or school to find examples of simple machines. Look for items like scissors (lever), a ramp (inclined plane), or a jar lid (screw). Draw a picture of each simple machine you find and write a sentence about how it helps make work easier.
Build a Mini Lever: Create your own lever using a ruler and a small object like a block or a book as the fulcrum. Try lifting different objects by placing them on one end of the ruler. Experiment by moving the fulcrum closer to or farther from the object you are lifting. What do you notice about how easy or hard it is to lift the object?
Design a Simple Machine: Imagine you are an inventor! Use materials like cardboard, string, and tape to design a simple machine that can help solve a problem at home or school. It could be a pulley to lift toys to a high shelf or a wedge to hold a door open. Share your invention with your classmates and explain how it works.

[Music] Clarendon Learning explores simple machines for kids.
Hey kids! In the beginning, everything had a starting point. Think about it: huge bustling cities started out as small towns with little buildings. We wouldn’t have supercars if Karl Benz hadn’t built his first motor wagon, and we never would have gone to the moon if someone hadn’t invented the wheel.
The wheel and axle is an example of a simple machine, and this is what we’re going to explore today: simple machines! Let me introduce you to some important helpers of mine. We call them simple machines: the inclined plane, the lever, the wedge, the screw, the wheel and axle, and the pulley. These tools have made the work I do so much easier. I’d like to show them to you, and I’d like you to use your imagination. Are you ready to learn about simple machines? Awesome! Let’s go!
Keep in mind that a simple machine has few moving parts and enables you to do more work with less effort and energy. Look at this person hoisting a sail with a simple machine. She’s doing more work with less effort. She’s crossing the ocean with a simple machine!
This is the inclined plane, where a ramp can be used to lift heavy objects from a lower level to a higher level. How much do you think this dump truck weighs? It weighs around 628 tons, which is 1,256,000 pounds! Whoa! This inclined plane is helping this machine get from a lower level to a higher level with ease. Using a gradual ramp makes it much easier to travel up and down. A ramp is also how a person in a wheelchair can get over a curb or into many buildings with multiple levels.
Maybe the ancient Pyramids of Giza used the inclined plane. I wonder what other simple machines might make good use of the inclined plane. How about the wheel and axle? Moving equipment up and down a ramp using wheels is easy. The wheel and axle are used all over the world for all sorts of things.
Here’s an example of my friend, Mr. Pottery Man. I wonder what he’s making. I bet it’s a cereal bowl to hold a lot of cereal! And what’s he using to make that cereal bowl? You’re right—a wheel and axle! Good job! The wheel is probably the greatest simple machine of all time. Think of everything the wheel can do and what we use it for. Just about everything in the world moves because of the wheel: planes, trains, automobiles, bicycles, unicycles, wagons, horse carts, pickup trucks, trucks, wheelbarrows, skates, and scooters.
Wait, whoa! Back up! Is that a six-wheeled truck? Whoa! The wheel and axle have made the work we do easier and recreation more fun. I mean, how fun would it be if a bike had square wheels?
Next, if you give me a fulcrum or a pivot and a plane, I’ll give you a lever! Actually, there are three types of levers, depending on where you put the pivot. Some examples of levers as simple machines are scissors, pliers, a baseball bat, and your arm and elbow. The lever gives us leverage to move things. A teeter-totter is a super fun simple machine—just ask Lily and Max!
The shovel is a combination of two simple machines: the lever and the wedge. Yes, the wedge is a simple machine and very powerful. With the wedge, I can split wood, cut through steak, chicken, and vegetables with ease. I like the wedge! I can use it as a doorstop to keep my door open. A nail is another example of the wedge—a very small but important simple machine.
Look at the screw—a simple machine all by itself! With the screw, I can attach things to a wall, drill a hole, or seal a bottle with a screw-on cap. And what about a spiral staircase? Yep, that’s a screw!
Now, let’s talk about the final simple machine: the pulley. The pulley is like a wheel but with a groove. With a couple of pulleys and a rope, you can exhibit superhuman strength! Look at this example of Mr. Kitty getting pulled up by a pulley. Look how huge that crane is! A lot of huge buildings all over the world are built by cranes—a simple machine. The elevator uses the simple machine technology of the pulley. Who loves elevator rides? I do!
We just learned about the six simple machines. Do you remember what they are? The inclined plane, the wheel and axle, the lever, the screw, the wedge, and the pulley. Great job! These are the simple machines that are around us every day.
When you assemble several simple machines together, you get cool things like cars, airplanes, and roller coasters. The bicycle uses many simple machines. Can you figure out what they are? Can you see the wheel, the lever, and the pulley? Good job!
Today’s assignment is to look around and identify the simple machines in the world around you. And while you’re at it, check out the Clarendon Learning activity pages made for your grade level.
