Standards & Objectives
3.1.4 A Know that natural and human-made
objects are made up of parts.
Identify system parts that are natural and human-made
(e.g., ball point pen, simple electrical circuits, plant
After completing the PowerPoint presentation and 3
activities, the learner will identify the six simple
machines and their functions with at least 90%
Simple machines make people’s live easier.
All the force needed to make simple
machines work comes from people.
Every simple machine picture in this
presentation was found on the playground.
Look around your house and school and you
might find some simple machines!!!
Types of Simple Machines
Wheels and Axles
An inclined plane is a flat surface that is higher on
All inclined plans can
help people gain speed
going down it. It helps
people because a roof
slant prevents the
heavy weight of snow
and rain from caving in
the roof. Have you ever
seen a ramp? It is an
We found some inclined planes on the playground
Slant on a roof
A lever is a simple machine that has fulcrum or a stationary
point. A lever needs a kind of force for it to work. The force is
also known as the effort.
There are plenty of
places in the school
where you could find
levers. Here are
some examples: the
playground, gym, in
the first grade
classroom, in the
kindergarten, and lots
A see saw is a lever, A swing is a lever.
it has a fulcrum in the The swing chains
connect to the
fulcrum, the top bar
A pulley is something that
pulls objects up, down
and sideways in the order
to make life easier.
Pulleys hoist things with
less muscle power.
Wheels are in
The only pulley we
found on the
playground is the flag
pole. It is used for
raising the flag up
A screw is
Screws help us to connect two objects together.
A few parts of these objects are screws:
Light bulbs Jars
A wedge is a simple machine used to push two
There are a lot of Shovel
wedges! Here are
Saw Hammer Can Opener
Wheels and Axles
Wheels help people get around faster. Axles help
the wheel turn.

Helps lift heavy weights
using longer distances
Pulley Makes lifting heavy weights easier
by redirecting force
Screw Turns rotation into lengthwise movement
Wedge Pushes material apart, cuts
Wheel Makes it easy to move things
and Axle by rolling them, and reducing friction
