     Teamwork is just as important in science as it is on the playing field or in the gym.Scientific investigations (调查) are almost always carried out by teams of people working together.Whatever the task your group is assigned, a few rules need to be followed to ensure a productive and successful experience.
     What comes first is to keep an open mind, because everyone's ideas deserve consideration and each
group member can make his or her own contribution.Secondly, it makes a job easier to divide the group
task among all group members.Thirdly, always work together, take turns, and encourage each other by
listening, clarifying, and trusting one another.
     Activities like investigations are most effective when done by small groups.Here are some more
suggestions for effective team performance during these activities:make sure each group member
understands and agrees to the task given to him or her, and everyone knows exactly when, why and what to do;be responsible for your own learning, though it is by no means unwise to compare your observations
with those of other group members.
     When there is research to be done, divide the topic into several areas, and this can explore the issue in a very detailed way.You are encouraged to keep records of the sources used by each person, which helps
you bring back the origin of the problems that may happen unexpectedly.A file for exchanging
information  (eg, photocopies of notes, oral discussion, etc.) is also important, for a wellchosen method not only strengthens what you present but also makes yourself easily understood.Most important of all, it is
always wise to make decisions by compromise and agreement.
     After you've completed a task with your team, make an evaluation of the team's effectiveness-the
strengths and weaknesses, opportunities and challenges.
