A Fun Plant Experiment to Try at Home
Without water, plants would die. How does water get from roots of a plant to the other parts of the plant? The water travels through" small pipes" to all parts of the plant. And here is a scientific experiment to show it.
What we need:
* a celery stalk(芹菜茎) with leaves
* a knife
* some red food colour from tomatoes
* a glass of water
How we do it:
1. Put a few drops of the red food colour in the glass of water.
2. Cut the bottom(底部) of the celery stalk and place the celery in the water.
3. Leave the celery stalk in the glass of water for a few hours.
4. Take the celery stalk out of the water and cut it into pieces across the stem.
What happens:
You can see red food colour in all cross parts from the bottom of the celery stalk right up to the leaves.
Why it happens:
The water, with the red food colour, has run in the celery stalk through the small pipes in it. The experiment, therefore, shows that the small pipes in the plant allow water to reach all parts of it. The red food colour shows where the water has travelled in the celery stalk.
As we all know, with the development of technology, smartphones have influenced the old people in our family a lot. A TV programme interviewed three teenagers on how smartphones influence their family.
My grandfather asked me to teach him how to play the popular video game King of Glory(王者荣耀). I was surprised that he was interested in this! He chats with family members on Wechat every day. He tries to learn other new things as well. For example, he watches courses on learning apps. Although he is old, he still cares about technology and sports. So, as we can see, the Internet can help elderly people. —Xing Yuxi, 12, Chongqing |
I live in Hangzhou, a city of technology. People enjoy the convenience(便利) brought by the Internet. However, I often worry about the elderly. Take my grandma as an example. On one hand, she would like to get discounts by using mobile phones. On the other hand, she's afraid of getting cheated online. I think it takes time for elderly people to get used to these things. We should help them keep up with the times. — Sun Run, 14, Zhejiang |
Smartphones have made a big difference in my grandma's life. In the past, newspaper and TV programs were her only ways to get information. However, it was not good for her eyes, as she has severe cataracts(严重白内障). But now, she can listen to the news through all kinds of apps on her mobile phone. She doesn't have to look at the screen all the time. Sometimes, she even plays mobile games for fun. Thanks to the Internet, my grandma now has a more colorful life. —Wen Jiayi, 13, Sichuan |
