QUESTION: Dear Marie,
Do you have some good suggestions of biology: plant, animal, human science experiments that would work well with teenagers? Scientific methods must go with the experiments. Thanks! <
Donna
ANSWER: Dear Donna,
Marie is not online and I’ll help you instead of him. There are a lot of little things that can be done, but do you mean lab experiment or statistical analysis, etc.? Let us know what can be suitable for you teens, and we will do our best to send you some experiments to do.
Best,
Gloria

QUESTION: Dear Gloria,
I need lab experiments. The teenage students and I will use data from these experiments to make charts, graphs, tables, etc. and to provide claims and evidence to explain more about the results. Thank you very much.
Donna
ANSWER:
Hi there,
Your best and easiest way is to do some chemistry experiments. Those are very easy and most probably you can do it in the lab and have charts, etc. for you. I do not have any particular one at the top of my head because I do cancer research and it is a bit more difficult than research for teenagers. I think you can look through these and see if you find something useful for you. http://www.siraze.net/chemistry/sezennur/experiments.htm
If not, get back to me and Marie, and we’ll look more. The good thing about this site is that it has the procedures that you can follow.
Good luck,
Gloria

After giving a talk at a high school, I was asked to pay a visit to a special student. An illness had kept the boy home, but he had expressed an interest in meeting me. I was told it would mean a great deal to him, so I agreed.
During the nine-mile drive to his home, I found out something about Matthew. He had muscular dystrophy (肌肉萎缩症). When he was born, the doctor told his parents that he would not live to five, and then they were told he would not make it to ten. Now he was thirteen. He wanted to meet me because I was a gold-medal power lifter, and I knew about overcoming obstacles(阻碍) and going for my dreams.
I spent over an hour talking to Matthew. Never once did he complain or ask, “Why me?” He spoke about winning and succeeding and going for his dreams. Obviously, he knew what he was talking about. He didn’t mention that his classmates had made fun of him because he was different. He just talked about his hopes for the future, and how one day he wanted to lift weights with me. When we had finished talking, I went to my briefcase and pulled out the first gold medal I had won and put it around his neck. I told him he was more of a winner and knew more about success and overcoming obstacles than I ever would. He looked at it for a moment, then took it off and handed it back to me. He said, “You are a champion(冠军). You earned that medal. Someday when I get to the Olympics and win my own medal, I will show it to you.”
Last summer I received a letter from Matthew’s parents telling me that Matthew had passed
away. They wanted me to have a letter he had written to me a few days before:
Dick,
My mum said I should send you a thank-you letter for the picture you sent me. I also want to let you know that the doctors tell me that I don’t have long to live any more, but I still smile as much as I can.
I told you someday that I would go to the Olympics and win a gold medal, but I know now I
will never get to do that. However, I know I’m a champion, and God knows that too. When I get to Heaven, God will give me my medal and when you get there, I will show it to you. Thank you for loving me.
Yours,
Matthew
How old was Matthew when they met?

Too many people want others to be their friends, but they don’t give friendship back. That is why some friendships don’t last very long. To have a friend, you must learn to treat your friend the way you want your friend to treat you. Learning to be a good friend means learning three rules: be honest; be generous (宽宏大量的);be understanding.
Honesty is where a good friendship starts. Friends must be able to trust one another. If you don’t tell the truth, people usually find out. If a friend finds out that you haven’t been honest, you may lose your friend’s trust. Good friends always count on one another to speak and act honestly.
Generosity means sharing and sharing makes a friendship grow. You don’t have to give your lunch money or your clothes, or enjoy, like your hobbies and your interests. Naturally you will want to share your ideas and feelings. These can be very valuable to a friend. They tell your friend what is important to you. By sharing them you help your friend know you better.
Sooner or later everyone needs understanding and help with a problem. Something may go wrong at school. Talking about the problem can make it easier to solve . Turning to a friend can be a first step in solving the problem. So to be a friend you must listen and understand. You must try to put yourself in your friend’s place so you can understand the problem better.
No two friendships are ever exactly alike (相同). But all true friendships have three things in common. If you plan to keep your friendships, you must practice honesty, generosity and understanding.
Some friendships don’t last very long because.
