early days, primitive people know little about the world. but gradually they discovered fire, farming and so on. nowadays human beings have stepped into a world of information age. the meaning of information age lies in the fact that people master information and make use of information. therefore, people who know more will do better jobs in their life and people who can discover more will own more information. but do you know what kind of people in our world discover more than ordinary people?ss: scientists know more and discover more than us. they make a difference between the known and the unknown.activity two: stimulate students curiosityt: yes, scientist can make a difference because they are curious about unknown things. then they work hard at it until they succeed. you can also make a difference if you are interested in something and make effort to work out it. this way you can also become a little scientist.ss: can we? in what way? in english class?t: surely you can. but before you become a little scientist, you should learn how to follow scientific procedures to make a discovery of the things that are unknown to you.step guidance on scientific proceduresactivity one: look at the examplet: now please turn to page 19. look at the bulletin board on this page and find what the topic of this bulletin board is about.ss: the bulletin board is about sea animals.t: in what way does the host of the bulletin want to present his works? ss: he wants to make a sea animal show for it.t: yes, it is very important to choose a topic that interests you or your group. also you should know in what way you can present your works. activity two: know how to design the bulletin boardt: what are included in the bulletin board? ss: two students are interested in the show and responded to it. one is interested in starfish and the other is fond of penguins. t: besides these, what can you see from it?sa: there are pictures of penguins and a starfish.sb: the background of the bulletin board includes sea water, fish and sea plants.t: yes, you have come the points. to make a bulletin board, we need to design it. bulletin board should be eye-catching and well designed. this way you may invite more people to respond to it. in this bulletin board, what items are include?ss: the bulletin board includes: a title, background design, introduction words, responses. activity three: respond to the topict: you have known the bulletin board well. now please present your response to it after surfing the internet and collecting information in the library, you can work in groups.the ss choose a sea animal and collect information. then present information about a certain sea animal.sa: i am always interested in sharks. so i have come to know something interesting about sharks the project.sas works:sharkssharks are fish that have been around long before the dinosaurs(恐龙) existed. they live in waters all over the world, in every ocean, and even in some rivers and lakes. unlike bony fish, sharks have no bones, and this makes it possible for dolphins to attack them. dolphins, on the other hand, have strong bones and they can attack sharks by jumping up and strike the sharks body. therefore, with many dolphins attacking from all the sides the shark will die soon. sharks may have up to 3,000 teeth at one time. most sharks do not chew their food, but gulp (大口吞咽) it down whole in large pieces. the teeth are arranged in rows. when one tooth is damaged or lost, it is replaced by another. most sharks have about 5 rows of teeth at any time. sb: i like killer whales because they are the largest dangerous animals in the world. so i made a study of their life.sbs works:killer whales socializing among killer whales includes a great variety of communication between members of the group. killer whales can be distinguished by the kinds of underwater communication sounds they produce - squeals and screams. killer whales have acute hearing and also acute vision both in and out of the water. when resting, whales slow down and at times stop altogether, and usually become very quiet underwater. periods of rest may last from less than an hour to more than 7 hours. they may travel from one good feeding spot to another, or it could simply be a means of transiting an area.step iii do-it-yourself projectactivity one: know the procedures to plan a bulletin boardt: it is no easy job to plan a project. we need careful plan and design before we carry out the project. but scientific procedures will ensure its success. now please look at the following sample procedures of making a project, choose a topic in groups and make a do-it-yourself project.the ss work in groups and try to do a project. after careful study the students will use the procedures to guide their own project plan.sample procedures:proceduresactivitiesprocedure onechoose a theme which interests the students in the same group.procedure two work out a plan.procedure threegroup leader assigns(布置) different tasks to each person.eg: sa and sb will design the background of the bulletin board; sc will work as the host to write inviting lines; sd will act as one of the student who respond; se will act as another person to respond to the show.procedure fourcollect information and carry out the tasks separately.procedure fivepresent the bulletin board to the whole class.activity two: assign the projectst: now you will be divided into groups, and you can work together to design a bulletin board by yourselves. i think everyone of you can do a good job.ss: form groups and choose a topic. then follow the procedures to carry out their tasks.step presentationactivity one: group one does presentationt: i will let one group present your bulletin board in class. first, group one will present your works.group ones leader: our group chose water sports as our theme.sa and sb: in our design we use water, sky and peoples exciting expressions as our background. this means that water sports provide people with enough water and wide range of sky, and people can enjoy themselves by simply joining in the sports. besides, water sports are challenging and this means that this kind of sports can give people great excitement. sc: i work as the host of the bulletin board. here are my lines: hello, everyone. sea sports, as one of the most important part of sports items in the olympic games, need your attention. you neednt have to be a skilled athlete or a real fan of the sport. you can show your love for the sport by simply put on information of sea
