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!!!

Types of Simple Machines

Inclined PlanesLeversPulleysScrewsWedges

Wheels and Axles

Inclined Plane

An inclined plane is a flat surface that is higher on one end.

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.

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.

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.

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.

Wheels and Axles Here are some

things that need a wheel and axle to work.

Car

Wheelbarrow

ScooterBike

Skateboard

Roller skatesMotorcycle

Activity #3 Compound Machines

Find as many simple machines as you can in the bicycle below. Circle each part and label it.

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
