Conclusion:

Ira’s grandmother says that green onions are very good for health. Ira decided to please her grandmother and grow green onions for her.

Ira read in a book how to do this. Here's what it said:

Pour unboiled water into a small jar. Such water contains more air, which the roots need to grow.
It is better to take a transparent jar to make it easier to monitor the water level.
Place the onion head on top of the jar with the bottom of the onion touching the water.
In order for the leaves to germinate together, the onion must be exposed to light in a warm place.
After 2 - 3 days you will see roots appear on the bulb.
When the roots grow, green leaves will “hatch” from the bulb.
Make sure the onion roots are always touching the water.
Wait until there are a lot of leaves, then cut them off and eat to your health!

18. Ira did everything as she read in the book, and then left for five days on an excursion to another city. When she returned, she saw that the roots had not sprouted. Five-year-old brother Sasha said that the cat Murka dropped a jar of onions. Sasha picked up an empty jar from the floor, put an onion in it and put it in the closet, away from the cat. Why didn't the onions sprouted?

1) For roots to germinate, light is required.

2) The cat scratched the onion, and the onion “died.”

3) Too little time has passed, you need to wait a little longer.

4) The bulb can only germinate when in contact with water.

19. In late autumn, Ira discovered several bulbs with sprouted roots and decided to plant them in a box on the balcony. Ira put on her coat, went out onto the balcony, planted onions in a box of soil and watered her “garden.” However, she failed to reap the harvest. Explain why the onion leaves did not grow?

Answer:

20. Walking along the edge of the forest, Kostya and Dasha saw near the path a chick that had fallen from the nest. The chick sat with a ruffled look; it seemed to the children that he was looking around in fear. Kostya and Dasha began to discuss what to do. The guys' statements are given below. Get to know them.

He is so small and cannot fly. Left without help, he will die, because there will be no one to take care of him. Let's take him home and feed him. And when he grows up and learns to fly, we will release him into the wild.

I heard that birds living in captivity cannot later adapt to life in the forest. It's better to leave him in the forest. His nest was probably destroyed by predators. Let's take it far away from here so that predators won't find it, and leave it somewhere in the thick grass.

Do you share the guys' point of view? Mark your answer with a sign✓ .

Explain why you hold this point of view.
