The Sun

THE SUN

Why is the sun important to life?

We need the energy from the sun for living things to grow!

Why is the sun important to human life?

FOOD

We need sunlight to help us absorb vitamins and minerals we need to grow big and strong!

If there wasn’t a sun where would our food come from?

How can the sun be toxic?

SUN BURNSKIN CANCER

EYE DAMAGEHEAT STROKE

What can protect us from the sun?

SHADE

STAY INSIDE DURING PEAK

SUN

Can we get closer to the sun?

YES

Are the sun’s rays stronger when you are closer to the sun?

• Think of a fireplace… when you are close to it, does it feel hotter than when you are on the other side of the room? YES

• When you are closer to the sun are the rays more powerful?

YES

What happens when…

What would happen if the sun no longer shined?

Plants would die People would get sick

Animals would have no plants to eatPeople would have no plants or animals to eat

THE FOOD CHAIN WOULD COLLAPSE

What would happen if you are closer to the sun?

You have to be even more careful of the sun!

There is less ozone to protect you from the suns toxic rays!

How could we protect ourselves more from the sun?

1.STOP POLLUTING! Pollution breaks down the Ozone layer

which helps protect us from the sun.

2.People can create things to help block those harmful rays!

What is pollution?

Pollution- is the release into the environment of toxic substances harmful to humans and the environment.

REVIEWWhat is the sun?

A source of energy that we need to live.

What is a toxin? A Poisonous substance.

Is the sun toxic? Yes, it can poison us. It can cause a sunburn, eye

damage, skin cancer, or heat stroke.

ReviewHow can we protect ourselves from the sun’s

toxic rays?

SHADE

STAY INSIDE DURING PEAK

SUN

Which of these things have people

created to help block the sun’s harmful

rays?

PowerPoint Presentation

The Pilot

THE PILOTand the Sun

Does the pilot have to worry about the sun being toxic?

YES

How will the pilot be exposed to the sun while flying?

Through the windshield and the sun will heat up the plane!

Remember the UV Frisbee experiment.

What happened to the Frisbee where the piece

of glass lay on it??? The Frisbee still changed color.

The glass did not protect the Frisbee from the UV rays!

Yes, the closer a person is to the sun, the less ozone there is to absorb/filter out some of the

sun’s harmful rays.

Closer to the sun = more toxic sun rays

Will the pilot’s contact with the sun rays be greater while flying than on

the ground?

What are some of the pilots tools for protecting himself?

Protective clothingFlight Suit

Eye ProtectionSun Glasses

Protection for your skinSunscreen

What can people do to help the pilot while designing his plane and tools?

PROTECT HIMDesign the windshield to reflect the UV rays.

Tint or darken the windshield so the sun is not so bright on the pilot’s eyes.

Design sun visors that effectively block some of the sunlight but do not block their view.

Design an effective cooling system so the plane does not get hot from the sunlight.

Design flight suits that protect from UV rays (some bathing suits now have

this).

Design sun glasses that cover the pilot’s full range of view.

What are the people that design planes called?

Aerospace engineers

Human factors engineers

Aircraft designers

Review

Because the pilot is closer to the sun making the sun’s harmful rays more powerful.

The pilot is exposed to the sun’s toxic rays through the windshield.

The heat from the sun will make the plane hot.

The rays from the sun can hurt the pilot’s eyes.

The sun’s rays could pass through the windshield exposing the pilot to a possible sunburn.

Why does the pilot need to worry about the sun?

ReviewWhat are the people that design planes called?

Aerospace engineers, human factors engineers, and aircraft designers.

What tools does the pilot have to protect him/herself?
