Few of us act alone in the real world. Most things are done with the help or ideas of other people. Group projects are great practice for high school, college, and real life, when you will probably have a job that requires working with others. Right now, group projects can be fun and they often allow you to do a bigger, more interesting project than you could alone. With group work, you can actually learn more in less time.

Group projects also give you a chance to get to know kids you might not otherwise know or talk with. Group projects are also a great way to practice skills you’re not so sure of. For example: working on a deadline, staying organized, or being patient. And if you’re a little nervous talking in front of a group, a joint project can help you become more comfortable with it. Maybe your group will pick you to tell the whole class about your project. If so, you’ll know your whole group is rooting for you!

One of the most important things about group work is talking and meeting together. It’s a good idea to continually check with everybody on their progress to see if anyone needs help. You might think the first step is to figure out who will do what, but actually it’s getting to know another a little. Take a few minutes to chat. Even if you know each other well, it can help to take a minute to think about your skills and share your strengths and weaknesses. The second step is to go over ground rules from your teacher and any that you want to create together as a group.

小组同学研究杠杆平衡的特点，他们先用弹簧测力计测出三个钩码的重力，如图（a）所示，然后将它们挂在已调节水平平衡的杠杆A点位置上，再用测力计在杠杆B点沿竖直方向用力使杠杆保持平衡，如图（b）所示，接着在保持杠杆水平平衡的情况下，改变测力计的用力方向，使测力计拉力方向与竖直方向的夹角不断增大，如图（b）、（c）所示。请仔细观察图中的装置、操作及现象，然后归纳得出初步结论。（将结论填入下面的空中）

（1）比较图中（a）与（b）两图，根据测力计示数大小与钩码和测力计位置等相关条件，归纳得出的初步结论是：                                                                        ；

（2）比较图中（b）、（c）、（d）三图中拉力方向和测力计示数大小可得出的结论是：

                                                                           。
