Six Simple Machines and a Flat Tire

While changing a flat tire on my car, as the jack was lifting the car, it seemed to me that there was science at work here. My husband explained that the jack was basically a screw, one of the six simple machines he remembers learning about. Not having a clue to what he was talking about, I did my Google homework and learned quite a bit.

Basically, there are six simple machines that help us push or pull items - they decrease the amount of work it takes to move objects over distances. For many years, these simple machines were seen as the elementary "building blocks" of which even more complicated machines were made.


My STEM Toys - Six Simple Machines and a Flat TireThe six simple machines, as first defined way back in the Renaissance, are:

  • Lever
  • Wheel and axle
  • Pulley
  • Inclined plane
  • Wedge
  • Screw

Why is it important to know and understand these simple machines? It is important because simple machines are in many devices that we use daily - such as highway ramps, wheelbarrows, crowbars, etc. For engineers, they are tools that help them solve everyday challenges.

There are some STEM (Science, Technology, Engineering and Math) toys that are specifically designed to teach kids about these simple machines - how they work and what are the scientific principles behind them.

Lever

A lever is a stiff bar that rests on a pivot (also called a fulcrum) which lifts or moves loads.


Engino Mechanics Discovering STEM Levers & Linkages

This is a fun product that teaches how levers can be used for increasing applied force to lift or change the direction of motion of an object. The kit includes a 14-page manual loaded with theories and facts with a 4-page quiz. There are 7 pages of experimental activities and includes enough parts to build 16 different working models using the theory of leveraging.

WHEEL AND AXLE

A wheel with a rod, called an axle, through its center lifts or moves loads.

Engino Mechanical Science: Wheels & Axles Construction Kit

Young engineers and scientists will enjoy the Engino set introducing them to the importance of the invention of a wheel. They can actually build five models including a tractor, motorcycle, door, car and car lift. It offers children to be creative with their own designs and experiments.

PULLEY

A pulley is a simple machine that uses grooved wheels and a rope to raise, lower or move a load.

My STEM Toys - K'NEX Education STEM EXPLORATIONS: Levers & PULLEYS Building Set Building Kit

K'NEX Education STEM EXPLORATIONS: Levers & Pulleys Building Set

Introduce your child to STEM concepts while building items that require pulleys and levers like a wheelbarrow, sailboat or a balance. This set has a booklet that guides children through three hands-on models teaching them about pulleys, resistance, effort and mechanical advantages.

INCLINED PLANE

An inclined plane is a slanting surface connecting a lower level to a higher level.

Engino Mechanical Science Inclined Planes Construction Kit

This set introduces young engineers and physicists to the use of inclined planes in moving heavy objects and how they are used in our everyday life. Five different models can be built including a splitting wedge, an automatic ramp with a car, a mobile airplane stair, and a vehicle with crane.

SCREW

A screw is an inclined plane wrapped around a pole which holds things together or lifts materials.



Engino Mechanical Science Screws Construction Kit

This educational STEM building kit has easy to handle colorful pieces which combines the use of wood and plastic. The kit has enough parts to build three different models with over 162 parts. Your young engineer can build structures or machines. This kit will introduce them to how worm gears are used to lower rotational speed and how screws can convert circular to linear motion.
