First,I poured 100ml of water into the beaker.Then,I added 50ml of oil slowly.To my surprise,the oil floated on top of the water!After that,we added a few drops of red food coloring.The food coloring went through the oil and mixed with the water,making the water look red.We observed carefully and took notes The experiment was agreat success!We learned that oil is less dense than water,so it floats.I was amazed by the colorful phenomenon when we added food coloring.This science experiment was very interesting. I not only learned about density but also felt excited about science.I hope to do more experiments in the future. 【满分范文逐段解析】 第一段（实验准备）： 时间状语Last week明确实验时间： 使用put on safety goggles和followed instructions强调实验安全规范： 材料列举清晰：beaker,water,oil,red food coloring。 第二段（实验过程)： 步骤连接词：First..The.After that..使流程清晰： 现象描写生动：floated on top,went through,mixed with; 科学观察行为：observed carefully and took notes体现严谨态度。 第三段（实验结果与感悟）： 原理说明简洁：oil is less dense than water; 情感表达真实：amazed by.felt excited about.; 结尾升华：learned about...hope to do more.体现科学兴趣培养。 1 初二上册沪教牛津版 【寒假专版】 满分范文及模板 满分范文模板 1.(:Last week,Yesterday,Last month),our science teacher asked us to do an experiment about ”2._”(实验主题：Water and Oil,Floating Eggs,Plant Growth)in class.We prepared3.一（实验材料： a beaker,some water,oil,and red food coloring;a glass,an egg,salt,and water;pots,soil,seeds,and a watering can).Before starting the experiment,.we4.一(C准备动作：put on safety goggles and followed the teacher's instructions carefully;read the steps and cleaned the tools;asked the teacher questions about safety). First,,I5.(第一步操作：poured 100 ml of water into the beaker,put an egg into a glass of water; planted seeds in the soil).Then,I6._(第二步操作：added50 ml of oil slowly,.poured salt into the water and stirred,watered the soil gently).To my surprise,.7.一（观察到的现象：the oil floated on top of the water!;the egg started to float!;the seeds sprouted after three days!).After that,,we8.一（后续操 added a few drops ofred food coloring;added more salt to see changes,measured the plant's height). The9.(实验对象：food coloring went through the oil and mixed with the water,,making the water look red,egg floated higher with more salt;plant grew taller in the sun).We observed carefully and took notes. The experiment was a great success!!We learned that10.(实验原理：oil is less dense than water, so it floats;salt water is denser than fresh water,so objects float better;plants need sunlight and water to grow).I was amazed by11.一（感到神奇的部分：the colorful phenomenon when we added food coloring;how the egg changed from sinking to floating;the way the seeds grew day by day).This science experiment was very interesting.I not only learned about 12.一（学到的知识：density,.buoyancy,.plant growth)but also felt excited about science.I hope to do more experiments in the future. 【模板填写指南】 1.实验时间（如：Last week,Yesterday) 2.实验主题名称（如：Water and Oil) 3.实验材料清单（如：a beaker,water,oi) 4.实验前准备动作（如：put on safety goggles) 5.第一步操作（如：poured water into the beaker) 6.第二步操作（如：added oil slowly) 7.观察到的现象（如：oil floated on water) 2 初二上册沪教牛津版 【寒假专版】 满分范文及模板 8.后续操作（如：added food coloring) 9.实验对象变化描述（如：food coloring mixed with water) 10.实验科学原理（如：oil is less dense than water) 1l.个人感受最深的现象（如：colorful mixing effect) l2.学到的核心知识（如：density) 填写示例： 1.Last week 2.Water and Oil 3.a beaker,water,oil,red food coloring 4.put on safety goggles 5.poured 100ml water 6.added 50ml oil 7.oil floated on water 8.added food coloring 9.coloring mixed with water 10.oil is less dense 11.colorful mixing 12.density 高分亮点总结 结构清晰：三段式（准备→过程→结果）符合实验报告规范 步骤连接：使用First..Ten.After that.…使流程连贯 现象描写：准确运用1oat,nix,go through等科学动词 原理阐释：用简单语言解释密度等概念(less dense than) 情感表达：To my surprise.I was amazed..增强感染力 时态统一：全程使用一般过去时，符合实验记录要求 写作小贴士·科学实验类作文 安全第一：必须包含安全措施描写（如put on safety goggles) 步骤有序：使用顺序连接词保证操作流程清晰 现象精准：用float/sink/mix/separate等准确描述现象 原理简明：用because/so简单解释科学原理 3 初二上册沪教牛津版 【寒假专版】 满分范文及模板 数据真实：包含具体数据（如l00 ml water)增强可信度 情感真实：通过surprised/amazed/excited表达科学探索感受 4
