Students, since the school launched the "Canal Citizen Day" activity, all our classmates have actively participated in it. So have you ever wondered why the word "canal" should be added before "little citizen"? Because we live by the canal, because the canal is our mother river ... Yes! Our Grand Canal is the longest and largest canal in the world and one of the oldest canals in the world. Today, let's walk into the Beijing-Hangzhou Grand Canal.
(2) Report of results
Students, recently our class launched a class activity with the theme of "Walking into the Canal". We visited the Canal Museum, and the students inspected the surrounding environment of the canal in the process of group activities. I heard it was very rewarding. In today's class, let's show our research results! Today, not only the guests in class, but also the experts from the environmental protection department come to our activities! Let's welcome them with warm applause!
1, praise team: (mainly through visiting the information collected by the Canal Museum, shooting the scenery of the canal, showing the history and culture of the ancient canal and the achievements made by government functional departments in managing the canal in recent years; And praise the canal through poetry reading and music. )
(1) All the students in our first group learned about the history, culture and value of the canal by visiting the Canal Museum. With the help of TV staff, we found a short film about the canal. Let's share it.
(2) Our team also inspected the environment around the canal, and learned from the mouth of nearby residents that in the past decade, with the efforts of the municipal government and all citizens, the face of the canal has undergone earth-shaking changes. Once upon a time, due to people's uncivilized behavior, the water in our ancient canal was turbid and gave off a stench. Some passers-by covered their noses and held their breath, and the fish and shrimp in the river died in groups. (Showing pictures) In recent years, the government has made great determination to manage the canal. Through everyone's efforts, the canal has taken on a new look. You see, this is a quiet and beautiful canal in the morning and a brightly lit canal at night. As a citizen of the canal, I hope all of us can join hands to keep the canal beautiful and let it shine forever.
(3) Finally, all our group members perform poetry reading: (Grading and showing the photos of the group members)
Canal ode
You are like a ribbon.
Floating from far away places
Grasping history is also tied to the future.
cross/travel/trek over mountains
Connect all corners of the country
You kissed the fertile soil affectionately.
You shine your life.
You hold hope in your hands.
You let the spring of the motherland bloom.
Qiantang spring tide is your character.
It's your feelings that all rivers run into the sea.
Silent dedication is your spirit.
This is your expectation for future prosperity.
Blue waves are your style.
The surge of spring tides is your spirit.
You will flow in my heart forever.
You will always be the love of my heart.
Yes, we are "canal citizens", so we are happy for its old look and new look, and we have the obligation and responsibility to protect it. Do you have anything to say after listening to the report of the first group of students? Although the environment of the canal has undergone earth-shaking changes through governance, there are still some disharmonies, aren't there? What did your team find?
And then what?
2. Shimizu team:
(1)ppt video demonstration experiment: During the activity, a group of our classmates found that the water in the canal was still turbid and garbage was floating on the water surface, so they studied the water quality of the canal. (Introduce yourself first. I am a member of Qingshui team (). We have a group of students, classmates of Qingshui team. Say hello to all the teachers present. With the help of parents, we collected water samples and tested them with PH test paper. It was found that the pH value was 7, which was weakly alkaline and reached the standard. Two small fish can be put in the bottle. 1 days later, a small fish died ... When we further investigated the environment around the canal, we found that there were many sewage outlets along the river, and sewage was continuously discharged from the nozzle. We also collected sewage from the sewage outlet and tested its PH value, and found that the PH value was (), which must have affected the water quality of the canal. If there is no sewage discharge, I believe the water in the canal will be purer.
(2) After listening to the second group's speech, do you have any thoughts? What is the PH value? How does this affect the evaluation of water quality? Where does the sewage come from? What impact will it have on the water quality of the canal? Is there any way to improve the water quality? How do relevant departments supervise? ……)
(3) Solving doubts: students solve doubts or experts supplement them.
(4) Summary: Yes, we are "citizens of the canal", and we have the responsibility to brainstorm and make suggestions for improving its water quality.
3. Escort:
The other two teams, report your findings quickly. Which group goes first?
(1) Sketch performance: The content to be reported by our security team can be presented by sketches.
(2) Students, do you understand what this sketch is about? This phenomenon is flat.
Have you seen it? Have you seen it yourself? (Yes)
(3) Photo display, interview: I heard that your escort also brought us a set of photos. Let's have a look. I want to interview the students who took this group of photos. What do you think when you see this phenomenon? How did you do it? Have you ever thought about discouraging them?
What are you going to say? What do you think we should do? (Inquiry: Start from yourself and appeal to people around you ...)
(4) We are citizens of the Canal, so we should start from ourselves and remind people around us not to litter.
4. Meishan team:
(1) Our Meishan team supplemented the Qingshui team and the escort team. Through our investigation, we found two phenomena (picture display): there are often people fishing by the canal? Students in our group have different views on this issue. Some students think that Hangzhou is a leisure capital, and fishing is very leisure. However, some students believe that the relevant departments prohibit fishing, and as citizens, they should abide by the law and cannot fish. What do the students think?
(2) Experts talk about opinions: From the perspective of environmental protection, whether it will affect water bodies.
(3) In addition, we also found that ships coming and going in the canal produce domestic garbage and oil pollution, which will also affect the water quality. Now that the means of transportation are so developed, can the ship stop it? (start a debate)
(4) Summary: For the health of our mother river, I am really happy to see the students' dedicated suggestions. So, what can we do for our mother river as canal residents? (start from yourself and establish a sense of responsibility; Call on others and publicize the sense of responsibility. )
So, students, why don't we write some slogans with a pen?
(3) Summary of the initiative:
1. Write a slogan
2. Rewrite three and a half sentences:
Dirty garbage is not littered.
Smelly sewage will not be discharged casually.
Don't fish by the canal.
Less slogans and more work.
It is everyone's responsibility to protect the canal.
Step 3 read together
Summary: Students, your slogan is very sincere. As descendants of the canal, we have an obligation to protect her and a responsibility to defend her. I am a "citizen of the canal" and it is my responsibility to protect the canal.
This is my answer, I hope it will help you.
