Using Our Senses to Gain Information

Return to Table of Contents

Slide 28 / 91

Our sense of sight, hearing

and touch are all used when we

use certain technology

devices.

Our Senses and Technology

Slide 29 / 91

Vision

Our sense of sight requires light waves in order to work.

What technologies require the use of sight?

Brainstorm at your table!

Slide 30 / 91

Sense of SightWe need our vision when we use different types of devices.

The device must be using visible light waves. That means the light is traveling to produce or make an

image that we can see. We see these waves as the colors of the rainbow.

Slide 31 / 91

HearingOur sense of hearing requires sound waves in order to work.

What technologies require the use of hearing?

Brainstorm at your table!

Slide 32 / 91

Sense of Hearing

We hear sound waves. Particles vibrate or move back and forth, allowing us to hear sounds. Technology uses the sound waves in certain devices.

Slide 33 / 91

Sound waves can give us information, even if we don't hear them. Two examples of this are sonar and

ultrasound machines!

Technology Using Sound Waves

Slide 34 / 91

Sense of Touch

Our sense of touch requires feeling vibrations in order to work.

What technologies require the sense of touch?

Brainstorm at your table!

Slide 35 / 91

Sense of Touch

When we use our sense of touch, we rely on forces to be able to feel. Not only do we sense patterns on our skin's surface, but we also have to use the positioning of our bodies. There are many technologies which require our sense of touch.

Slide 36 / 91

Before certain technologies were invented, if you lost a hand

or leg, you were very limited. Now people can compete in

sports and live very well.

Doctors use sound vibrations to hear what is happening on the inside of our bodies.

Slide 51 (Answer) / 91

Sonar : Sound Navigation and Ranging

Sonar uses sound to communicate with or find objects under the surface of the water.

Certain animals use Sonar as well - can you think of any?

Slide 52 / 91

Microphones

Microphones change sound waves into electrical waves so that it can be sent to a speaker so you can hear the sound waves better.

Computers also have microphones which helps us communicate by using

Skype for example.

Slide 53 / 91

"Voice Activated"

Have you seen people talking to their phones? Or even talking to their car?

If an electronic device is voice or sound activated, sound waves are translated into electronic messages.

This icon means you can talk to the device.

Slide 54 / 91

Ultrasound

Ultrasound is a technology used by doctors and veterinarians. They can see an image of what is inside a

person or animal. Ultrasound technology uses sound waves to view inside the body because it is easier and safer than

an X-ray.

Gaining Information Using Radio Waves

Return to Table of Contents

Slide 64 / 91

Radio CommunicationRadio waves transmit music, conversations, pictures and data invisibly through the air, often over millions of miles --

it happens every day in thousands of different ways! Which of these do you use?

Slide 65 / 91

We use radio waves to send information and communicate. Radio waves link cell phones over great distances.

Your cell satellite satellite satellite cell your cell tower dish dish tower friend's phone

Cell Phones Use Radio Waves

Slide 66 / 91

Cell Phones Use Radio Waves

If the cell phones are near to each other, the path is shorter.

This cell phone tower is "disguised"

as a tree.

Slide 67 / 91

Wireless Radio waves

What wireless devices can you name?

Slide 69 / 91

Radio Waves

Radio waves are all around us, everyday, all the time.

We can not see, hear or feel them.

How do the waves get to the right device? The radio waves actually go everywhere. They have a frequency

that is specific for the receiver. Do you remember frequency from the unit on sound we did earlier this year?

So, your radio controlled car is not started by the garage door opener, even if it is in the garage.

day.

If you are using a Smart board right now, it is using light to project the data it

receives from the computer!
