IV. Teaching process: (preset)
(1) Inspiring conversation (playing video)
Students, since the "Canal Citizen's Day" was held in our school, all our classmates have actively participated in it. So have you ever wondered why we should add the word "canal" 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.
(II) Report on Achievements
Students, recently, our class launched a class activity with the theme of "Walking into the Canal". We visited the Canal Museum, and our classmates inspected the surrounding environment of the canal in the process of group activities. I heard that it was very rewarding. In this class today, let's show our research results! Today, not only the guests attending the class, but also the experts from the environmental protection department came to our activities! Let's welcome them with warm applause!
1. Praise team: (Mainly show the history and culture of the ancient canal and the achievements made by government functional departments in managing the canal in recent years by visiting the materials collected by the Canal Museum and shooting the scenery of the canal; And praise the canal through the form of poetry reading with music. )
(1) All the students in our first group learned something about the history and culture of the canal and its value by visiting the Canal Museum. And 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 recent ten years, 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 the uncivilized behavior of people, the river 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. (Show pictures) In recent years, the government has made great determination to manage the canal. Through everyone's efforts, the old look of the canal has taken on a new look. Look, this is a quiet and beautiful canal in the morning, and this is a brightly lit canal at night. As citizens of the canal, I hope that all of us can join hands to keep the canal beautiful and make it shine forever.
(3) finally, All our team members present a poem recitation for you: (score and show photos of team members)
Ode to the canal
You float from a distant place like a ribbon
Leading history and tying the future
Crossing mountains and mountains
Connecting all corners of the country
You kiss fertile soil with deep affection
You shine with life
. China's spring is full of flowers
Qiantang spring tide is your personality
All rivers run into the sea, your feelings
Silent dedication is your spirit
Prosperity is your expectation
Blue waves are your grace
Surging spring tides are your spirit
You will always flow in my heart
You will always be my favorite
Yes. After listening to the report of the first group of students, do you have anything to say? Although the environment of the canal has undergone earth-shaking changes through governance, there are still some discordant places, aren't there? What
did your team find?
2. Qingshui Team:
(1)ppt video demonstration experiment: During the activity, our classmates found that the water in the canal was still muddy and there was garbage floating on the water surface, so we conducted research on the water quality of the canal. (Let me introduce myself first. I am a member of Shimizu Team (). We have a group of students, classmates of Shimizu 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 the pH value was up to standard. Two small fish were put in the bottle, and one day 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 the sewage was continuously discharged from the nozzle. We also collected the sewage at the sewage outlets and tested its PH value, and found that the PH value was (), which must have affected the water quality of the canal. If there was no sewage discharge, I believe the canal water would be purer.
(2) After listening to the second group's speech, do you have any thoughts? (What is the PH value? What effect does this have on evaluating 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 the relevant departments supervise? .....)
(3) Solve doubts: students solve doubts or experts supplement doubts
(4) Summary: Yes, we are "small citizens of the canal", and we have the responsibility to brainstorm and offer suggestions for improving its water quality.
3. Escort team:
The other two teams, come and report your findings quickly. Which group will come first?
(1) sketch performance: what our security team will report can be presented by a sketch.
(2) Students, do you understand what this sketch is about? Have you ever seen such a phenomenon in Ping < P >? Have you ever seen it yourself? (Yes)
(3) Picture presentation, 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 did you think when you saw this phenomenon? How is it done? Have you ever thought about discouraging them?
what do you want to say? What do you think we should do? (inquiry: start from ourselves and appeal to people around us ...)
(4) We are "canal citizens", so we should start from ourselves and remind people around us not to litter.
4. Meishan Team:
(1) Our Meishan Team supplemented the contents of Qingshui Team and Escort Team. Through our investigation, we found two phenomena (picture display): there are often people fishing by the canal? On this issue, the students in our group have different opinions. Some students think that Hangzhou is a leisure capital, and fishing is very leisure. However, some students think that the relevant departments prohibit fishing, and as citizens, they should abide by the law and not fish. What do the students think?
(2) Experts talk about whether it will affect water bodies from the perspective of environmental protection.
(3) In addition, we also found that the coming and going of ships in the canal has produced domestic garbage and oil pollution, which will also affect the water quality. Nowadays, the means of transportation are so developed, can we stop the ships? (start a debate)
(4) Summary: For the sake of the health of our mother river, I am really glad to see my classmates making such conscientious suggestions. So, as canal citizens, what can we really do for our mother river? (start from yourself and establish a sense of responsibility; Appeal to others and publicize the sense of responsibility. )
So, classmates, why don't we just get a pen and write some publicity slogans!
(3) Summary of the initiative:
1. Write propaganda slogans
2. Rewrite three and a half sentences:
No littering of dirty garbage
No dumping of smelly sewage
No fishing by the canal
Less slogans and more work
Everyone is responsible for protecting the canal
3. Read the summary together
.
this is my answer. I hope it will help you.
