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 |

According to the dictionary definition of“create, ordinary people are creative every day”.To create means“to bring into being, to cause to exist something each of us does daily”.
We are creative whenever we look at or think about something in a new way. First, this includes an awareness of our surroundings. It means using all of our senses to become aware of our world. This may be as simple as being aware of color and texture(质地),as well as taste, when we plan a meal. Above all, it is the ability to notice things that others might miss.
A second part of creativity is an ability to see relationships among things. If we believe the expression,“There is nothing new under the sun, the creativity is remaking or recombining(重组) the old in new ways.”For example, we might do this by finding a more effective way to study or a better way to arrange our furniture, or we might make a new combination of camera lenses and filters to create an unusual photograph.
A third part of creativity is the courage and drive to make use of our new ideas, to ask for them to achieve some new results. To think up a new idea is one thing; to put the idea to work is another.
These three parts of creativity are included in all the great works of geniuses, but they are also included in many of our day-to-day activities.
1.“There is nothing new under the sun” really implies that _________.
A.a new thing can only be created at the basis of earliest things
B.a new thing is only a tale
C.we can seldom create new things
D.we can hardly see really new things in the world
2.What does the author think about the relationship between a new thought and its being put into practice?
A.It’s more difficult to create a new thought than to use it in practice.
B.To find a new thought will clearly lead to the production of a new thing.
C.A man with an excellent ability of practice can easily become an inventor.
D.One may come up with a new thought, but can not put it into practice.
3.The best title for this passage is__________.
A.How to Develop One’s Creativity B.What Is Creativity
C.The Importance of Creativity D.Creativity, a Not Faraway Thing
