Hey there! Today, we’re going to explore something super cool called simple machines. These are special tools that help us do work more easily. Imagine how big cities started as small towns, or how we have fast cars today because someone invented the first motor wagon. Simple machines have been helping us for a long time!
Let’s meet some of these amazing helpers:
These simple machines make our work easier by using less effort and energy. Are you ready to learn more about them? Let’s go!
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 as much as 1,256,000 pounds! An inclined plane makes it easier for the truck to move up. Ramps are also helpful for people in wheelchairs to get over curbs or into buildings. Maybe the ancient pyramids were built using inclined planes!
The wheel and axle are everywhere! They help us move things easily. Think about cars, bikes, and even pottery wheels. My friend Mr. Pottery Man uses a wheel and axle to make bowls. Wheels help planes, trains, and even skates move smoothly. Isn’t that awesome?
A lever is a simple machine that helps us lift things. It’s like a seesaw on a playground. Scissors, pliers, and even your arm are examples of levers. They give us the power to move things with less effort. Have you ever played on a teeter-totter? That’s a fun lever!
The wedge is a powerful simple machine. It helps us cut or split things. A knife is a wedge that can slice through food. A doorstop is a wedge that keeps the door open. Even a small nail is a wedge that holds things together. Wedges are small but mighty!
The screw is a simple machine that holds things together. It can attach shelves to walls or keep a bottle closed with a cap. Screws are everywhere, and they make sure things stay in place. They may look like spirals, but they’re super helpful!
The pulley is like a wheel with a groove. It helps us lift heavy things with ropes. Imagine pulling up a flag or lifting Mr. Kitty with a pulley. Cranes use pulleys to build tall buildings. Elevators use pulleys too, and they’re so much fun to ride!
Let’s see if you remember the six simple machines:
Great job! These simple machines are all around us. When we put them together, we can create amazing things like cars, airplanes, and roller coasters. Even bicycles use simple machines like wheels, levers, and pulleys. Can you spot them?
Now it’s your turn! Look around and see if you can find simple machines in your home or school. They’re everywhere, and they’re super fun to discover!
Thanks for learning with us today. We hope you had a blast! For more fun learning, visit us at learnbrite.org. See you next time!
Simple Machine Scavenger Hunt: Go on a scavenger hunt around your home or school to find examples of simple machines. Can you find a lever, like a pair of scissors or a seesaw? How about a wheel and axle, like a toy car or a rolling chair? Make a list of all the simple machines you discover and share them with your friends or family.
Create Your Own Simple Machine: Use household items to create a simple machine. For example, you can use a ruler and a small object to make a lever, or stack books to create an inclined plane. Try to lift a small toy using your lever or roll a ball up your inclined plane. How does it make the task easier?
Think and Draw: Imagine you are an inventor in the past. Draw a picture of a simple machine you would create to help people in your town. What problem does it solve? How does it work? Share your drawing and explain your invention to your class or family.
Sure! Here’s a sanitized version of the transcript:

Welcome to our exploration of simple machines for kids!
In the beginning, everything had a starting point. Think about it: huge bustling cities started out as small towns with modest 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
– 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 should enable you to do more work with less effort and energy.
Look at this person hoisting a sail with a simple machine. They’re doing more work with less effort while crossing the ocean!
This is the inclined plane, or ramp. It 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 million two hundred fifty-six thousand pounds! Whoa! This inclined plane is helping this machine get from a lower level to a higher level with ease.
Using a gradual ramp enables you to travel up and down much easier. A ramp is also how a person in a wheelchair can get over a curb or into many multi-level buildings. Maybe the ancient pyramids of Giza were built using the inclined plane!
What other simple machine 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, hand trucks, wheelbarrows, skates, and scooters.
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 the lever as a simple machine are scissors, pliers, and a baseball bat. Your arm and elbow are also good examples of the lever.
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 with a knife. I can cut through stakes 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, and seal a bottle with a screw-on cap.
What about curly fries? I don’t think they’re a simple machine, but they sure do look yummy, and I’m getting hungry!
The screw is a very cool simple machine, which brings us to 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 large 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
– The pulley
Great job! These are the simple machines. They’re around us every day, and 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.
