Science is about asking questions. A science fair project is an experiment or a research effort. Through such a project, you learn how to find problems and how to solve them.

    A science fair project includes at least three parts: the display poster board, the exhibit (展览) materials, and the written report.

    The display poster board

    The display poster board is very important. It is what people first see. As a kind of "advertisement" for your project, it must be carefully designed. Usually, the board should include the key points of your research.

    The exhibit materials

    These materials can be the most exciting part of any science project. They usually include the items you used in your project. Together, they tell a story. People should be able to understand your project on their own through these materials.

    The written report

    No matter what you do, you need to record your findings in a written form. The written report should include all the information you collected while you were working on your project. The report may also include your understanding of the topic you choose.

Tired after eating?

 After a busy morning, lunch can feel like just something necessary but sometimes it also makes you want to take a break at your desk. 

{#blank#}1{#/blank#} This is because when humans eat, our blood sugar level is raised after receiving energy from food, which may cause tiredness after meal. Feeling tired can make it hard to focus on the rest of your studies and activities. Here's why and how to improve the situation. 

{#blank#}2{#/blank#} Some people overeat instead of stopping when they feel full. For example, when having buffet, people often eat more than they expect. {#blank#}3{#/blank#} Because we usually feel tired after working the whole morning without breakfast. This will make us eat more at lunch. 

 The make up of certain foods can also cause you to feel tired. If you had a meal high in fat, such as a hamburger or a pizza, that could make you feel tired. Meals high in added sugar can have the same effect. {#blank#}4{#/blank#}

 If you don't get enough sleep, your body increases production of ghrelin, which sends a " feed me" signal to your brain. Not getting enough rest can also have a bad influence on your decision making skills. {#blank#}5{#/blank#}
 

It was a February afternoon. We were in a classroom. Taylor Angler watched some ducks swimming on a farm. But it was all in her head. A virtual reality headset（虚拟现实头戴式显示设备） took her there. "I was surprised to find that the ducks were right in front of me! It was an exciting experience（经历）." Taylor said after taking off the purple headset and finding herself still in the classroom. Many students around the world are taking VR "trips" like Taylor. But what change does it cause in learning? 

Taking children to visit different places is a good way to teach them about the world. But what can children do if they forget it after the trip? VR lets children go back at any time. 

It's difficult to talk about something if you didn't see it with your own eyes in the past. If you didn't see the ocean, with VR, now you can have a look at it for yourself. 

VR can also help students in science classes at school. "Too often at school, when you do experiments（实验）, you put different kinds of chemicals together and then get the result. And if you aren't successful, you need to do it again," a high school teacher said. "But we don't have enough chemicals. With VR, I just need to do it again on the computer. I don't have to use chemicals."

VR is useful, but that's not to say we don't need real-world experiences. The real world is what we really need to learn about. 

The following is some news from old students of the Islamabad University !

Teachers' Day is an important holiday in China, and it has been around for thousands of years in some ways! 

In old times, a similar holiday 1 by people on the birth of Confucius. Besides celebrating Confucius' birth, all teachers had2 day off and received dried meat as gifts. Excellent teachers3 got silver coins. 

Modern Teachers' Day in China was set up by the government in 1985. The government hoped4 more people would know the importance of teachers through celebrating this holiday. Now, people celebrate Teachers' Day5 September 10th every year. 

One of6 Teachers' Day celebrations is visiting the old school. This allows students who have graduated (毕业) to show thanks to7 old teachers. For students still in school, there are many ways 8 thanks to their teachers, such as sending cards, writing letters, or giving flowers. Many schools have class celebrations on this day as well. For example, some classes will give "Most Popular Teacher" awards. 

In China, people9 teachers to gardeners (园丁) and students to flowers. This comes from the idea that students need love and care to grow10 , just like flowers, And, of course, the most skilled gardeners grow the most beautiful flowers!
