Wheel and Axle for Kids Simple Machines Lesson

Join us as we learned about the wheel and axle. This Wheel and Axle for Kids lesson is a fun, hands-on, and engaging simple machines lesson for preschool, pre k, kindergarten, first grade, 2nd grade, 3rd grade, and 4th grade students.  Learn about how this simple machine, how it was used in history, and try one of our simple machine projects.

Wheel and Axle

A wheel and axel is a simple machine where a wheel turns around a bar to move objects.  In this wheel and axle for kids lesson we will look closer at how this simple machine words with a hand-on wheel and axle activity, read informative pictures, books, and have a chance to explore the 6 simple machines. This simple machines science lesson is perfect for preschoolers, kindergartens, grade 1, grade 2, grade 3, and grade 4 students.

Wheel and axle for Kids

Wheels and axles include things like sharpeners, doorknobs, Ferris Wheels, wheels on cars, flour grain, and more.

    

Here are some of the books we read to prepare for our second week studying simple machines :

Wheel and axle Activity

For one of our experiments I had the kids try to push a brick across the counter. They observed how the friction from the weight and the brick’s surface made it difficult. We briefly talked about how before we had modern machines it would have been very difficult to move large stones, but that it could be done. Then we read a couple books to explore:

• Stonehenge. England – they used lots to roll the heavy stones
• Pyramids, Egypt – they used inclined plains to move heavy stones

We attempted both methods and discovered for our purposes of moving over a flat surface rolling over “pencil” logs worked really well.  The logs were a version of a simple machine – the wheel.

Simple machine projects

For this simple machine project, we started off by rolling a Styrofoam ball. Balls roll in all different directions and aren’t as easy to control. I asked the kids if a ball was different from a wheel.  Then I cut off the sides of the Styrofoam ball to show that wheels are really the centers of balls.

Love the light bulb that went on in their eyes!

Before I could even suggest it, my 3rd grader stuck a pencils through the middle and said – “Look Mom, I made an axel.” Someone was listening to the books we were reading! After having them push it around for a while we made a second Styrofoam wheel and joined it with the same axel. It was a lot easier to turn.

K’NEX Simple Machines

Last Christmas I found these K’Nex Education sets on super deal so we decided to try them out. We love Lego, but they are SO expensive. K’Nex are fun, easy to use, and great for teaching STEM; we have been so impressed with these K’Nex kits. The pieces are so versatile and the educational guide explains simple machine along with instructions to create 7 models.

Our favorites were the well (pictured at the top of the post – the kids played with it for hours) and the car with the working steering wheel.

I highly recommend the K’next Education Simple Machines: Wheel & Axel and Inclined Planes. It is such a great way for kids to be able to visually see and put into practice what they’ve learned. We are huge fans of hands on learning!
