Many people enjoy the beauty of the snow. But do you really know the snow? Here are three biggest snow myths that will surprise you.

First of all, it’s a myth that no two snowflakes are the same. In 1988, a scientist found two identical snow crystals that had both formed in a snow storm in Wisconsin, USA. Since then scientists have come to learn that snowflakes can only form into 35 different shapes. Although scientists are also unsure why exactly the various shapes of snowflake form, they have identified eight major shapes, with each of these eight shapes having several different variations.

“Snow is white” is the second biggest myth. It’s actually colorless. Snow is made up of ice particles, and ice is translucent, which means that light does not pass through it easily, but rather it gets reflected. When light hits a snowflake, it gets reflected back from the snowflake’s many surfaces, often bouncing between these surfaces, and because of this that light is reflected back to our eyes as the color white. This is why, up close or magnified, a snowflake always looks clear, yet in reality appears as white.

Lastly, snow doesn’t always appear to us as the color white. Not counting the infamous yellow snow that everyone knows never to eat, you can also get naturally blue snow or even pink snow.

Deep snow can sometimes appear blue in color because the extra layers of snow create a filter for light, which causes more red light to be absorbed by the snow than blue light, meaning that it looks blue.

Likewise, snow can sometimes appear pink in mountainous regions or coastal Polar Regions due to it containing cryophilic fresh-water algae that have a red pigment in them.

As an interesting bonus fact, the fur of Polar Bears is actually made up of translucent fibers, trapping light between its many surfaces and making the Polar Bear look white, when in actuality if you were to examine a single piece of Polar Bear fur up close it would look clear – just like a snowflake.

It’s also a commonly known fact that, if shaved, a Polar Bear would be black in color. The reason a Polar Bear’s skin is black is because black is the color which locks in the most heat.

1.According to the passage, the underlined word “myth” means _________.

A.tale B.riddle

C.mystery D.misunderstanding

2.Why does a snowflake appear as white?

A.Because snow is white.

B.Because snow is made up of ice particles.

C.Because ice is translucent, light does pass through it easily.

D.Because the lights reflect back and forth between the snowflakes’ surfaces.

3.Which of the statement is true?

A.Polar Bears’ black skin can help them keep warm.

B.The color of the snowflakes are white, yellow, blue and pink.

C.Scientists have identified eight minor shapes of the snowflake.

D.The snow absorbs more blue light than red light, making it look blue.

4.Which of the following doesn’t belong to the three biggest snow myths?

A.Snow is white B.Snow always looks white

C.No two snowflakes are the same D.Polar Bear fur looks clear--just like a snowflake.

Museums have changed. They are no longer places that one “should” go to but to enjoy.

At a science museum in Canada, you can feel your hair stand on end as harmless electricity passes through your body. At the Children’s Museum in New York, you can play an African drum. There are no “Do Not Touch” sign in some other museums in the USA.

More and more museum directors have realized that people learn best when they can become part of what they are seeing. In many science museums, the visitors are encouraged to touch, listen, operate and experiment so as to discover scientific rules for themselves.

The purpose is not only to provide fun, but also help people feel at home in the world of science. If people don’t understand science, they will be afraid of it; and if they are afraid of science, they will not make the best use of it.

One cause of all these changes is the increase in wealth and spare time. Another cause is that the number of young people grow in the population. Many of them are college students or college graduates. They see things in a new and different way. They want art that they can take part in. The same is true of science and history.

The old museums have been changing and the government is encouraging the building of new, modern museums. In the States and Canada, there are more than 6000 museums, twice as many as there were 25 years ago.
