Water is the source of life, and we must protect every drop. If there is no water, the earth will split; if there is no water, we humans will die of thirst; if there is no water, there will be no beautiful world and home. Therefore, we must cherish every drop of water. Here is an essay on saving water for third-grade students, which I hope will be helpful.
Essay 1 on Saving Water for Third Graders
I finished my homework early today and watched TV after dinner. My mother told me to wash my face and then watch TV. I agreed. Then I went to wash my face. When I arrived, my mother was washing her face. I said, "Hurry up, Mom." She replied, "Okay." I was waiting for my mother to finish washing her face. My mother washed her feet in the same basin of water. I said, "Mom, why are you doing this?" She asked me why. I said, "It's to save water." Mom really knows how to teach me. She washed her socks in the same basin of water. My mother said that if everyone could save water like this, how much water could be saved in a year?
Today, my mother gave me a lesson in water saving. Now it's my turn to wash my face and feet. Ah, washing your feet can eliminate the tiredness of the day. It's good to save water.
Essay 2 on Saving Water for Third Graders
Many students in our school run to the faucet as soon as they enter the classroom. They open the faucet and then throw water into the basin. When they leave, they do not turn off the faucet but run away quickly.
I used to do such a "stupid" thing.
When I was young, my parents were not at home in the evening. I was scared to be alone at home, so I ran to the bathroom to play with water. When the water was finished, I left the faucet running. The next morning, all the water was on the ground. My parents had to mop up all the water and take off the mop and rag. They just wanted to sit on the sofa and rest. I felt bored again and then opened the faucet. I sat on the sofa and watched cartoons without turning off the faucet. The longer the faucet is left running, the more water is wasted.
When my parents came home, they told me not to play with water again. Playing with water was a great hazard to the country. Since then, I have not played with water again.
Later, every time I washed dishes and face, I thought, "I can't waste water and harm the country. I can't harm the motherland!"
Essay 3 on Saving Water for Third Graders
Today, I saw a problem on my math exercises. The topic is: Our country has about 130 million people. If we save 1 cent per person per day, our country will save about 1.3 million yuan a day. So this money can provide children with no money to go to school.
Looking at the information above, I thought, "What a force!" I suddenly thought: if these 130 million people, each person had wasted one drop of water, then altogether wasted 130 million drops of water, then, how much water does 130 million drops have?
I conducted an experiment: I dripped 1000 drops of water under the tap and weighed them, which weighed 200 grams. I counted the drops as 260 tons.
I don't know. It's a shock. I went to ask my father, "Daddy, how much electricity can one ton of water generate?" Dad said, "One ton of water can generate 100 degrees of electricity." That means 260 tons of water can produce electricity. I was shocked at once. 260 tons of water had so many functions. So we must save all water and not waste a drop.

節約用水作文800字三年級5篇
水是生命之源,生命之本,人類的健康離不開水。因此我們有必要節約用水,不要浪費水資源。下面是我為大家收集的節約用水作文800字三年級例文,希望你喜歡。
節約用水作文800字三年級(精選篇1)
大樹的翠綠是因為水的滋潤,鮮花的美麗是因為水的滋潤,好吃的蔬菜水果也是因為水的滋潤,我們的身體有三份之一是水……世界沒有水的話,那就可怕死了
水,是生命之源泉。水是大自然賜予人類最珍貴的禮物。滴滴水珠、涓涓溪流、滾滾浪濤、滔滔江水,我們的一生都不能離開水,也離不開水。
對于水,每個人都認為水是取之不盡用之不竭的。正因為如此,在如今的21世紀中,水資源伴隨著環境的污染正悄無聲息的流逝。水資源的短缺也成為了當今世界面臨的重大危機。世界上的水只有十分之三的水是可供人類使用的淡水,而這些彌足珍貴的水資源也正在我們的浪費中失去。這樣維持不了多久,人類就會滅亡,世界的生靈將慘遭厄運,我們一直捍衛的地球也終將在我們的手中被摧毀,變成一片廢墟。這也將是人類繼續浪費水的后果。可是,即使這樣,我在校園中卻發現了一種可恨的現象。當天,我從洗手間出來,發現那兒的水龍頭壞了,一滴滴清澈的自來水猶如江水一般,滔滔往外流,我費盡心思想把它關好,但總不能如愿以償,我馬上叫來一個健壯的男生,請他幫忙。
根據所提供的信息,改寫后的內容如下:
1. 地球上只有大約三分之二是淡水,而且這些淡水大多分布在極地,以冰的形式存在,使得可供人類飲用的淡水資源非常有限。然而,許多人并沒有意識到節約用水的重要性,仍在浪費這些寶貴的資源。如果不加以改變,人類和地球上的其他生物將面臨嚴重的生存危機。
2. 有一次,我在農村旅游時,看到一個水龍頭壞了,自來水不斷地流失。當我試圖關閉水龍頭時,一位叔叔卻告訴我不用管它,因為那是自來水,用也用不完。他的態度讓我感到震驚,我告訴他水是有限的,我們應該節約用水。盡管他沒有完全接受我的觀點,但我至少讓水龍頭的水流小了一些。
3. 我們離不開水,一旦沒有了水,就等于沒有了生命。我們應該從個人做起,節約用水,比如重復使用洗衣服的水來澆花或沖廁所,洗手時關閉水龍頭等。只有每個人都行動起來,我們才能真正節約大量的水資源。
4. 保護水資源是我們每個人的責任。我們應該意識到,水資源的浪費和污染不僅威脅到我們的生存,還會對生態系統和生物多樣性造成嚴重破壞。我們應該珍惜每一滴水,用實際行動來保護這個美麗的地球。
5. 為了我們共同的家園,讓我們攜手合作,弘揚節約用水的傳統美德,共同為保護水資源做出貢獻。
