How does a rocket fly? There is gas(气体) in the rocket. When the gas inside the rocket got hot enough, it will rush out of the end of the rocket. So it can make the rocket fly up into the sky.     

    Rockets can fly far out into space. Rockets with men have been to the moon. Several rockets with men have flown to another planet much farther away than the moon. One day rockets may be able to go to any place in space.

Information Card

    A blind boy sat on the steps of a building with a hat by his feet. He held a sign which said, "I am blind. Please help me."

    There were only a few coins in the hat. A man was walking by. He took out a few coins from his pocket and dropped them into the hat. He then took the sign, turned it around, and wrote some words on it. He put the sign back so that everyone who walked by could see the new words.

    Soon the hat began to fill up. A lot more people were giving money to the blind boy. That afternoon the man who had changed the sign came to see how things were. The boy recognized(认出) his footsteps and asked, "Are you the one who changed my sign in the morning? What did you write?"

The man said, "I only wrote the truth. I said what you said, but in a different way."

    What he had written was, "Today is a beautiful day, but I cannot see it."

    Do you think the first sign and the second sign were saying the same thing?

    Of course both signs told people the boy was blind. But the first sign simply told people to help by putting some money in the hat. The second sign told people that they were able to enjoy the beauty of the day, but the boy could not enjoy it because he was blind.

:I think kids learn better by studying for tests. If you actually sit and study what you are supposed to learn, you'll remember it. Hands-on projects might end up making a kid feel stressed if they are trying to finish on time, and If you are stressed, you might not learn as much.  {#blank#}1{#/blank#}

:When people study, they remember what was in the book. If they know they have a test, they will most likely to take notes on all the important information to help them with the test, so they will learn it better.  {#blank#}2{#/blank#}

:With a hands-on project, you can be creative while you learn. It's also a lot more fun than sitting at a desk with flashcards. Plus, with a hands-on project, you can learn more than you expected. It's more satisfying to learn on your own without someone explaining it to you.  {#blank#}3{#/blank#}

:Hands-on projects are better. When you are studying for a test, it can get boring and then you can get distracted(注意力分散的). You learn better doing projects because it is not boring and you experience new things depending on what you are doing.  {#blank#}4{#/blank#}

:I think kids learn hands-on projects because they have to consider the topic, instead of just memorizing information that they'll forget about after the test. Also, completing a project is good for spending time with your friends or family.  {#blank#}5{#/blank#}

    When it comes to the letter grade on your test or homework, you might notice that there is no letter E. Have you ever thought about why that is so?

    In the A, B, C, D and F grading system, the first four letters are typically considered passing grades. An F in this system simply stands for "fail". The word "fail" happens to start with the letter F, which seems to leave out the letter E.

    The first college in the US to use a letter grading system like the ones we use today is Mount Holyoke College. In 1897, they began to use the following grading scale;

    A: 95-100% (excellent)         B: 85-94% (good)      C: 76-84% (fair)

    D: 75%( nearly passed)         E: below 75% (failed)

    We can see the inclusion of E instead of F.

    Gradually, the letter grading system became more popular all over the US. However, many schools decided to drop the E grade and go straight to F. There is no evidence(证据) to really support this, but one possible explanation is that teachers were worried that some students and parents might mistake E for "excellent".

    Why do we have letter grades? Well, part of the reason is that they made grading simpler during a time of great change for schools. As the 20th century began, growing cities and an increase in immigration led to larger school classrooms. Most teachers at that time thought this new letter grading system was an easy, fair and clear way to grade students.

    Today, more and more people think that letter grades don't fully show students' learning. However, as teachers try to improve grading methods, many parents continue to prefer the letter grades they got as kids, as they are familiar and easy for parents to understand. So while they might not be perfect, the letter grades probably aren't going away any time soon.
