It’s Simple!

Demonstration Storyboard by Dot Garman

Screen #1

Audio Narration Visuals

In this lesson you will learn about the six

types of simple machines and how they

make our lives easier. By the end of this

module you will be able to sort and label

simple machines into their correct

categories.

.

Simple Machines – Lesson Objectives

Students will accurately sort and label objects into the simple machine categories.

Screen #1


Simple machines are devices that

make work easier for us. Without

any motorized parts, a simple

machine will increase or change the

force needed to accomplish a task.

Simple machines are all around us.

In fact, you have probably used a

simple machine today. Do you have

a bicycle? If so, the hand brake is a

simple machine called a lever. Your

bicycle chain uses a simple machine

that is called a pulley, and the tire

uses the wheel and axle simple

machine. I’m sure there are bolts on

your bicycle . . . that is the simple

machine called a screw. And if you

rode your bike over a ramp, you

used an inclined plane. Last, if you

have ever experienced a flat tire,

you could have run over a wedge

simple machine, such as a

thumbtack, nail, knife or razor.

Let’s move on to learn about each

simple machine in more detail.

Simple Machines – Tools for Making Work Simple

Instructions for Interactivity The screen will open with the image of the bicycle.

As each simple machine is mentioned, the item and its associated label will appear around the edge of the bicycle.

Images and labels will appear in the following order: 1. Top left picture with label “Lever.” 2. Label “Pulley” and arrow pointing to the bike chain. 3. Label “Wheel and Axle” with arrow pointing to the wheel and axle. 4. Label “Screw” with arrow pointing to the screw on the handlebar. 5. Bottom left image with label “Inclined Plane.” 6. Top right image with label “Wedge.”

Screen #2


Let’s start with the simple machine called a

lever. A lever is a straight, solid item that is

supported against another object. The

object that supports the lever is called a

“fulcrum.”

Levers make our lives simpler by helping us

do common tasks. Did you turn on a light

switch lately? If so, you used a lever! If you

ever handed in an assignment that was

more than one page, you may have used a

lever to keep them together – a stapler. A

fun recess activity for young children is

playing on a lever called a seesaw or

teeter-totter. And we all use a very common

lever every day, the little handle that flushes

the toilet.

What other levers have you used recently?

Functional Instructions

The screen will open with the text only.

As each item is mentioned, it will appear on the screen. Items will appear in the following order: - Light Switch - Stapler - Seesaw - Toilet

Screen #3


Now let’s talk about the simple machine

called a wedge. A wedge is used to cut,

chip, or push items apart. A wedge will

normally have at least one side that is

slanted with a narrow or sharp edge that

cuts, splits, or opens the object.

Some examples of wedges are:

Scissors

Knives

Door stops

Chisels

Wedges



As each item is mentioned, it will appear on the screen.

Screen #4


Let’s take a moment to see if you can

distinguish between a lever and a wedge.

Drag each picture to the correct area.

CA:

Nice job! You have identified different lever

and wedge simple machines.

What is a lever and what is a wedge?

Instructions for Interactivity

Display items on the screen with instructions

As students drag the items, they will snap in place if they select the correct area.

As students drag the items, they will snap back if they select the in correct area.

Correct answers: Stapler and seesaw are levers. Axe and hedge trimmers are wedges.

When all items are correct, display CA.

Wedges

Levers

Screen #5


A pulley uses grooved wheels with a rope,

cord, or chain to move objects. Pulleys

simplify our lives by allowing us to move

heavy objects or things that are in hard to

reach places. Some examples include:

Elevators

Buckets in wells

Theatre style curtains

Construction equipment

Pulleys




Screen #6


The inclined plane is a flat surface that is

arranged at a slant. It makes life simpler by

allowing things to be moved with less effort.

Some examples include:

Ramps

Slides

Bathtubs (the bottom of the bathtub

is slanted to allow water to drain out)

Inclined Plane




Screen #7


Let’s do another check of your knowledge

of simple machines.

Drag the text box “inclined plane” to

the image of an inclined plane.

Drag the text box “pulley” to the

image of the pulley simple machine.

CA:

Well done! You understand what simple

machines are pulleys and inclined planes.


Display items on the screen with instructions

As items are moved to the correct picture, they will snap in place.

As items are moved to incorrect pictures, they will snap back. Correct answers are: Handicap vehicle ramp is an inclined plane. Construction pulley is a pulley.

When both items are correct, display CA.

Inclined Plane Pulley

Screen #8


Another simple machine is the screw.

Basically, it is an inclined plane wrapped

around a cylinder. They simplify our life by

holding things down or together. Some

examples of screws are:

Drill bits

Jar lid

Light bulbs

Screw <Sketch a representation of on-screen visuals here.>>




Screen #9


The last simple machine is made up of two

parts, a wheel and an axle. The axle is a

rod that is placed through the wheel. As the

axle turns, it moves the wheel. It makes our

lives easier as it allows us to move objects

that we would not be able to move on our

own. Some examples include:

Tires on cars and bicycles.

Roller skates

Pencil sharpener

Wheel and Axle




Screen #10


We will now pause to see if

you can distinguish between

the six simple machines. Click

on a picture and drag to the

name of the simple machine.

CA:

Well done! You have

successfully identified the six

simple machines.


Display items on the screen with instructions.

A line will be drawn from the picture to the word as the student drags and drops.

If the item is correct, the line will remain in place.

If the item is incorrect, the line will disappear and beep sound will play.

Correct answers are:

Wheel and Axle

Wedge

Inclined Plane

Pulley

Screw

Lever

Wheel and axle is the roller paint brush. Wedge is the fireman prying open a door. Inclined plane is the treadmill. Pulley is the construction equipment hoisting a big blue box. Screw is the light bulb. Lever is the nutcracker. When both items are correct, display CA.
