The Little Prince meets Science

Marble

It's tasty but it's a little bit sour. Why is that?

It's amazing out here! Look at the stars and the planets!

So he got into his plane and started his travel.&nbsp; But let us see what happened………

A rainbow can be formed when light falls on a cd or on a glass of water

Well let me tell you how a rainbow is formed

&nbsp;When the white light falls on a triangular glass prism, it is seperated  into seven spectrum colours that they have different wavelengths of the light

Rainbow

It's a scale 0-14 that measures the acidity.The closer a compound is to 0 the more acidic it is.

Watch the light coming out along with a streamline

what are they doing over there? Do they perform the same experiment because the bubbles are different

No it's another experiment that is called "elephant's toothpaste" Yeast reacts with hydrogene hyperoxide and the oxygen that is produced is trapped in dish detergent creates the foam

You can create a rainbow nutralizing an acid with a base

Acid is a compound that when dissolved in water gives Hydrogen cations

I think you got caught into a ray of light and that changed your course.

Even a glass may become invisible due to refraction of light

When light travells in vacuum or in the air has a maximum&#160; velocity 300.000 Km/s which is called speed of light.

Refraction of light? I've never heard about that.

Due to refraction a straw may seem broken

Hey. Look over there. A rainbow! I didn't notice it was raining.

But they have one property in common. They both change the color of indicators

Don't be afraid. Some students are perfoming&#160; experiments with vinegar and soda

Volcano 6th Junior High School of Veria

Would you like a glass&#160; of lamonade?

But then his plane started shaking and got out of its course. Suddenly he crashed to earth

Oh my god. Where am I? How did I get here?

And he decided to walk around and find someone ...

Elephant's toothpaste

They are substances that change their color according to the pH of the solution

When a ray of light in a medium of higher index of refraction&nbsp;&nbsp;approaches the other medium at an angle of incidence greater than the&nbsp;critical angle total internal reflection takes place at the boundary between two transparent media and the light remains trapped in the first medium

Once upon a time there was a little prince&nbsp; that he wanted to explore the world.

I love your school. But what's happening over there? Is there a volcano in the yard? I'm scared! Let's run!!!

When an acid reacts with a carbonate, carbon dioxide is produced which is a gas. That causes the bubbles. Let me show you.

I'm so happy that I've met you. I've learnt so many things. Thank you. I'll never forget you!!!

She seemed so friendly and Little Prince had so many questions ...

I think I know what happened. Have you ever heard of the refraction of light ?

I was travelling in the space with my plane and then something happened and my plane crashed. I wonder what&#160; happened?

Another compound is base that when dissolved in the water gives Hydroxide anions

But when it travells in other optic medias its velocity is lower. That causes a change in its course.

You are in Greece. Don’t be afraid. My name is Ann.

I think it's better to show you. Come with me.

Wow! I can understand now what you meant before.&#160;

Refraction&nbsp;is the bending of light  as it passes from one&nbsp;transparent&nbsp;substance into another.This change of direction is caused by a change in speed.
