shape, pod colour, pod shape, flower position and colour. He
used selective breeding to observe these traits over generations,

A short bio
Mendel was an Austrian monk who
chose to continue his education and
explore his scientific ideas. He was
happy that he was able to study

while also conducting experiments
about variation in plants.

Winter holidays are shorter than summer ones. They begin at the end of December and last about two weeks. It is so nice to have a rest from school.

During winter holidays we celebrate the New Year’s Eve and Christmas. There are New Year parties for children at schools and theatres. Cinemas show children films and cartoons.

It is usually very cold in winter, but frost and snow can’t keep children indoors. It’s so great to go skiing down a hill. Boys like to play hockey on the ice. Many children go to the skating-rinks to skate. Small children play snowballs and make snowmen, or ride on the sledges happily.

When the weather is bad, I stay at home and watch TV. There is always something interesting on during winter holidays. Sometimes my friends come to see me and we play computer games or listen to music. There is also more time for reading, drawing, making model planes and other hobbies.

Holidays pass quickly and soon it’s time to go to school again.
