На уроках Science мы изучаем строение растений.
Очень интересный и важный вопрос: как вода с питательными веществами поднимается от корня по стеблю вверх? Мы провели интересные эксперименты, добавляя краситель в воду, в которой стоят растения В результате познакомились с "капилярным эффектом", благодаря которому питательные вещества, растворенные в воде, по стеблю попадают в листья и цветки.
How does the stem work?
During the Science lessons in our school, our first graders wanted to do some experiments.
As they have been studying various parts of plants and their functions, we have decided to do the experiment with the stems of the plants.
In our Science class children did this experiment and they showed it to their parents at home as well.
The students observed the colored water traveling through the stems making their flowers colorful.
Water travels up tiny tubes in the plant by a process called “Capillary Action”.
Adding a colored dye into the water in the vase allows them to observe capillary action at work. This was the main aim of the experiment. All first graders did it successfully and got immense positivity.
