What would happen if you tried to blow a soap bubble in freezing weather? Would it freeze solid(固体) and fall to the ground? Would you have to hit it to break it? These questions happened to me on a cold winter day. It was too cold to play in the snow, but it was a perfect time to experiment with blowing frozen bubbles.
To blow frozen bubbles, I used dishwashing soap and a drop of glycerin(甘油) to make it even better. I chose a place out of the wind, and blew bubbles the same way I always do. I watched to see what would happen. Here’s what I learned.
If the temperature is low enough, the skin of the bubbles frosts over (结霜), becoming cloudy instead of clear. And what about those rainbow swirls(旋转) you see in soap bubbles? The rainbow colors stay even when the bubbles frost, but they don’t swirl anymore. The bubbles still stay in the air. They don’t fall to the ground any faster than they would on a warm summer day.
When these frozen bubbles break, they don’t turn into small water drops as summer bubbles do. They turn into flashing rainbow confetti(碎屑) and move slowly to the ground. Sometimes a frozen bubble will roll across the snow without breaking. If nothing disturbs the bubble, it may stay there for a long time. Sometimes I could catch a bubble and hold it until the heat of my hand made it pop.
I learned another thing about blowing frozen bubbles. It’s so interesting that I want to try it again next year.

“I hate school, and I’m not going back!”Have you ever had that thought?
Lots of kids have had. Usually this feeling doesn’t last long. But what if you feel this way too much? If you are stressed out, you might have a hard time making decisions. In the morning, you can’t decide what to eat, what to wear, or what to take for lunch. Sometimes it’s a problem with your classes and schoolwork. Maybe the work is too easy and you get bored. Or maybe the work is too hard, or you don’t feel as clever as the other kids. Reading may be difficult for you, but you are asked to do a lot of it. You may be getting farther and farther behind, and it may seem that you will never catch up with others. When you know why you don’t like school, you can start taking steps to make things better
It’s a good idea to talk to someone about your problems at school. Your mom, dad, friends, teachers, or even classmates will be able to help you.
Another good idea is to write down your feeling about school. For instance, keep a diary or just write in a notebook. It’s a great way to let out emotion that may be stuck inside you. And you don’t have to share(分享)what you have written with others.
The next time you find yourself disliking school, this will also help you:
Make a list of everything you dislike or enjoy—even there is only one thing. See what you can change on “don’t like” list. Could you find a way to show off your special interests and talents on what you like? Which activities could you try that would help you solve these “don’t like” problems? Focus on what you can change and you might be able to put the good feeling back in school!
