Children's simple snowflake paper cutting step by step illustration

Children's simple snowflake paper cutting step by step illustration:

Materials: a piece of plain white paper and a pair of scissors.

Steps:

1, find a square piece of white paper.

2.Then fold it in half.

3.Fold it again to make a small square.

4. Then fold it twice diagonally.

5. Fold into one of the shapes shown.

6. Use scissors to cut out two types of snowflakes.

7, the finished product.

Snowflakes, also known as silver corn, jade dragon, jade dust, is a kind of crystal, is the water vapor in the sky by condensation of solid precipitation, the structure changes with the temperature, more hexagonal, like flowers.

Snowflakes are extremely shaped, each snowflake is an extremely fine pattern, even many artists have marveled. Snowflakes are mostly hexagonal, which is because they belong to the hexagonal crystal system. Cloud snowflake "embryo" of small ice crystals, mainly in two shapes.

A kind of hexagonal, long and thin, called the pillar crystal, but sometimes its ends are pointed, like a needle, called needle crystal. The other is in the form of a hexagonal flake, like a thin slice cut from a six-pronged pencil, and is called a flake crystal.

Snowflakes, a kind of crystal, is the water vapor in the sky by condensation of solid precipitation, the structure changes with the temperature, also known as the united flower and six out, a beautiful crystalline, it is in the process of drifting down in clusters to climb together, the formation of snow flakes.

Individual snowflakes are usually between 0.05 and 4.6 millimeters in size. Snowflakes are very light, weighing only 0.2 to 0.5 grams individually. No matter how light and small and marvelous a snowflake is, its crystals are regularly hexagonal.

So the ancients had "more than five flowers of grass and trees, the only snowflake six out of the" statement, the world's history of science writings are recorded as the earliest Chinese know the hexagonal structure of the snowflake.
