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 anatomy).
Objective: After completing the PowerPoint presentation and 3
activities, the learner will identify the six simple machines and their functions with at least 90% accuracy.

Introduction
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!!!

Inclined Plane
An inclined plane is a flat surface that is higher on one end.
![Page 7: My Presentation On Simple Machines](https://reader034.vdocuments.us/reader034/viewer/2022052410/548a9c81b479595b4d8b458f/html5/thumbnails/7.jpg)
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 inclined plane.

Inclined Plane We found some inclined planes on the playground

Levers
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.

Levers
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 more!

Levers
A see saw is a lever, it has a fulcrum in the center.
A swing is a lever. The swing chains connect to the fulcrum, the top bar

Pulleys
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.
![Page 13: My Presentation On Simple Machines](https://reader034.vdocuments.us/reader034/viewer/2022052410/548a9c81b479595b4d8b458f/html5/thumbnails/13.jpg)
Pulleys
Wheels are in pulleys!
The only pulley we found on the playground is the flag pole. It is used for raising the flag up and down.

Screws
A screw is an inclined plane that winds around itself.

Screws
Screws help us to connect two objects together.

ScrewsA few parts of these objects are screws:
Clocks
JarsLight bulbs
Water Faucet

Wedges A wedge is a simple machine used to push two
objects apart.
![Page 18: My Presentation On Simple Machines](https://reader034.vdocuments.us/reader034/viewer/2022052410/548a9c81b479595b4d8b458f/html5/thumbnails/18.jpg)
Wedges There are a lot of
wedges! Here are some examples:
Fork &Knife
Shovel
AxeScissor
Saw Hammer Can Opener

Wheels and Axles
Wheels help people get around faster. Axles help the wheel turn.
![Page 20: My Presentation On Simple Machines](https://reader034.vdocuments.us/reader034/viewer/2022052410/548a9c81b479595b4d8b458f/html5/thumbnails/20.jpg)
Wheels and Axles Here are some
things that need a wheel and axle to work.
Car
Wheelbarrow
ScooterBike
Skateboard
Roller skatesMotorcycle

SummaryInclined
PlaneMakes it easier to move objects upward; a longer path, but easier lifting
Lever 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
Wheeland Axle
Makes it easy to move things by rolling them, and reducing friction

Conclusion
Basic Types
Designed to make work
Few or moving parts
Combine to form complex machines
