So, how to go about writing an essay? The following is my collection of interesting experiments sixth grade essay, welcome to read, I hope you can like it.

Interesting Experiments Sixth Grade Essay 1

One evening, I saw several articles from the composition book, which were written about doing experiments. When I saw these articles, a thought quickly came into my head: right! Why don't I do a little experiment too? This can improve my hands-on ability and make me understand some truths at the same time, I should give it a try. Thinking of this, I leapt up from the sofa.

From the articles, I chose one of them, which was about the topic of "whether potatoes contain water". I did it. I immediately ran into the kitchen and found the ingredients I needed: salt, a spoon and a large potato. Next, I started to do what the article said, step by step.

First, I took out the potato, placed it in a safe place, and dug a shallow pit above it with the spoon. Next, I carefully used a spoon to get a shallow spoonful of salt out of the salt shaker, and then poured this salt, without missing a single drop, into the long-dug pit on the potato. Finally, I walked gently into the living room with the potato in my hands and set it on the windowsill, then left satisfied and began to speculate on what would happen in a few hours.

That evening, I walked out onto the living room windowsill right on time to see what had happened to the potato. To my surprise, I realized that the little puddles on the potatoes were filled with water! What in the world was going on here? I was so puzzled that I had to go to the book to find out why. It turned out that it was the salt at work, it precipitated all the water out of the potato cells. Similarly, salt can also precipitate water in the human body. I finally understand, no wonder I feel thirsty after eating too salty food!

This experiment was not only interesting, but also made me realize another truth. It seems that everything in life, you need to practice in order to come to a conclusion!

Interesting experiment 6th grade essay 2

Today my dad took me to do the egg salt water test on the Academic Assessment - the egg will float on the water.

I first found a teacup and put it in the water. My father said, "Put the egg in and see if it sinks or floats." It is well known that the egg must sink, and without thinking I answered, "Sink." Dad said, "Now let's experiment by adding salt little by little and see how many salt eggs will float." So I first put in a spoonful of salt, stirred it evenly with chopsticks, and put in the egg, which was heavy. Two spoonfuls, three spoonfuls, four spoonfuls, five spoonfuls, I kind of couldn't stand my temper and yelled, "Dad, the egg can't float, this experiment can't be done." Dad laughed and said, "Don't worry, when the salt water reaches a certain concentration, the egg floats." "You didn't realize that people don't sink into the Dead Sea, did you? The same goes for salted eggs. Mom said while it was hot.

I took the trouble to put the salt in for the sixth time. I put the eggs in carefully, but they haven't floated yet. On the seventh, eighth, ninth, and tenth spoonfuls, the big end of the egg floated up. I jumped three feet high in joy, "Yes, it worked!" Dad put the brine in a mineral water bottle and said, "This brine weighs about a pound.

In this experiment, I not only know that eggs can float in salt water, but also know that people should be patient.

"It's turning brown!" "It's turning brown!" A shout of excitement came from the classroom. How on earth could this be? It turned out that we were doing an interesting experiment.

Under the guidance of Mr. Cao, I prepared a candle, a match, a small spoon and a small amount of sugar. After the preparations were done, I put the small spoon with sugar on the fire. After about 5 minutes, the sugar was smoking, and after another 3 minutes, the sugar was bubbling. I looked at the sugar in the spoon and shouted, "Come and see, why are the bubbles brown instead of white?" The teacher smiled and said, "You're really observing carefully!" Hear the teacher's praise, I feel happy, and continue to observe carefully. The see into the brown place at first only a grain of rice so big, gradually become a soybean so big, and then to the fingernail so big, and finally all turned into a brown solid.

Why does sugar turn brown? We were puzzled, so we asked the teacher for advice. Mr. Cao said with a smile: "Sugar is a carbohydrate, is water and carbon mixed together in a certain proportion. When white sugar is heated to a certain degree, the combination of water and carbon is broken, and the water separates from the white sugar, creating a new substance, the brown carbon solid." Oh, I see! Seeing the look of realization on everyone's face, the teacher smiled heartily.

This experiment is so interesting, it allows us to understand the scientific truth, but also let us reap the benefits of happiness.

Science, it opens our eyes, makes us full of curiosity and excitement, let us see so many things and strange things from it. It's like a bottomless pit how to see can't see the edge ......

Once, I saw my sister doing an experiment: a cup full of water, and then a piece of paper to seal the mouth of the cup, and then turn the cup upside down, I think the water will be but the water will be broken through the paper, and then out, but the water did not flow out a drop! ...... I think it's simply impossible, so a thin piece of paper, how can a cup to hold up?

So I decided to try it myself. After preparing the props, I will fill the cup with tap water, a paper cover the mouth of the cup, with the hand will be the rest of the paper cup ring, and then inverted the cup, and then carefully look at the paper, the water inside the water does not move, but the paper is a little bit wet, I thought that the water will certainly flow out, but after a long time, the paper did not break, and the water did not move a little bit.

At night, I filled the cup with half a cup of water, in front of mom and dad "show" again, but this time I do not know how, when the water is poured over a drop of water flowed down. I don't believe it, I did it again, and this time I finally succeeded.

But why did the water flow down? I looked online, finally found the answer: it turns out that when the water cup filled with water, cover the paper after the cup in the atmospheric pressure is lower than the cup outside the atmospheric pressure, the cup outside the atmospheric pressure on the pressure only, the water will not flow out. But if it is half a cup of water, then there is half a cup is air, the atmospheric pressure is greater than the atmospheric pressure in the cup, so the water flowed out.

Saturday night, my mom gave me a problem, what can be used to make the egg float on the water? I first said, "Add gasoline to the cup." Mom shook her head, came over for a moment and said, "Put the egg in a fully inflated balloon." She shook her head again. Mom said, "Want to know how?" I pricked up my ears.

Mom then said, "The way is simple, just add salt to the cup." I was puzzled, she explained: "When the salt is added to a certain amount, the specific gravity of the salt water is greater than the specific gravity of the egg, then the egg can float on the water." After listening to my mom's words, I was still half convinced. Decided to try their hands.

Now, everything is ready, all we need is an east wind. I couldn't wait to dart to the kitchen.

First I got a cup, an egg and a packet of salt. Then I added the right amount of water to the cup, and then carefully put the egg into the water. Then I added a little bit of salt to the cup. However, the egg did not move. I said to myself, "What's going on? Did I not add enough salt?"

The second time I tried it, I took the plunge and poured half a packet of salt into the cup. I thought to myself, "There's still salt left anyway, enough for mom to cook with. Besides, my courageous spirit will be recognized by my mother. Just when I was complacent, a miracle happened! The egg really floated a little. I was so excited that I continued to add salt to the cup, and finally the egg floated on the cup. I jumped for joy.

After the experiment, I was excited to go to my mom, she saw my eyes have narrowed into a line, but also silly smile.

Last week in science class, the teacher asked us to bring play dough, wooden blocks, ping pong balls, leather balls, glass bottles, foam, tin, small stones and other items, ready to do science experiments.

On the experimental class, the teacher said to us: "You now do a test to see what can sink in the water? What can float in the water?" The students through the experiment, know the playdough, iron, small stones into the water and sink, and wooden blocks, ping-pong balls, leather balls, foam, glass bottles can float in the water. The teacher then asked, "How can I make playdough float in water?" I flattened the playdough with my hands, and then wrapped in foam thrown into the water, the playdough really floated. The teacher saw and shook his head and said, "Let the playdough float, not with the help of anything else." I had to think of another way. I pinched the playdough into the shape of a boat, and then carefully put into the water, "playdough boat" floating in the water, I was very happy, and quickly asked the teacher to look at my "masterpiece", the teacher smiled and nodded, I was happy. Teacher again asked: "You can let the glass bottle sink?" I heard, the glass bottle lifted high, and then thrown into the water, I thought I could sink, but the glass bottle drilled to the bottom of the water and then quickly "climb" up.

At this point, I thought that when I was swimming, I could hold my breath and float, and when I exhaled, I would sink. So I opened the lid of the glass bottle, so that the glass bottle broke the gas, filled with water, then only see the glass bottle shook a few times on the sinking. Through hands-on experiments, and fun, and interesting, but also to learn a lot of knowledge.

"Students, if you don't use glue, tape and other adhesive things, the newspaper can stick to the wall and not fall off. Do you know why this is? Well, today we are going to do a little experiment 'Electrified Newspaper'!" The teacher told us. I heard to do a small experiment our interest as if all of a sudden by a rope to lift up the general, immediately high emotions, eyes brushed staring at the teacher, look a little impatient!

The teacher took out a piece of newspaper and a pencil, "Watch out, I'm going to do some magic! We watched with rapt attention, not blinking for fear that we would miss a part of the show!

The teacher put the newspaper on the wall, "Class, if I take a pencil and rub it on the newspaper many times, what will happen to the newspaper?" Before the teacher finished, the students began to discuss it enthusiastically. Some put their hands up directly; some seem to be like a "contemplative"; some are scratching their heads and can't think of anything; and some simply ran directly to the podium and asked the teacher, who just shook his head and smiled mysteriously, but the smile was meaningful ......

When the teacher took the pencil and rubbed it against the wall several times, he said, "What would happen to the newspaper? p> The moment the teacher picked up the pencil, the students' necks stretched out like geese being picked up, staring at the pencil with round eyes. "Brush, brush." The pencil rubbed on the newspaper for a while, and the newspaper actually stuck to the wall, what's going on? It turns out that the pencil friction produces static electricity, electricity has a kind of suction, before the newspaper will be firmly sucked.

It seems that there is science everywhere around us, just that we did not go to find it.

Through this small experiment, not only enriched our knowledge, but also enriched our after-school life, really make us benefit a lot!

Today, the science teacher arranged for us to go home to do an experiment: to explore the reasons why the cactus is drought-resistant. As soon as I got home, I was forced to prepare the experimental materials, according to the requirements of the teacher to start the experiment.

I first took out three paper towels, came to the pool, let them fully dipped into the water. Then carefully put the three pieces of paper on the outside is "accepting" the hot sun on the plastic paper, one of the paper is flat, another paper rolled into a thin pole like . One of them is laid flat, the other is rolled up in the shape of a small cylinder like a thin pole, and, of course, the last sheet of tissue paper is wrapped in a small, airtight coat of wax paper. Well, it's time to rest for a while. Yikes! Don't just walk away, you're only halfway through the experiment, and there's still more to come! Really still everything is ready, all we need is the east wind ah!

"One minute ...... ten minutes ...... fifty minutes ...... sixty!" I was so excited that I quickly walked to the door and squatted next to the three pieces of paper. I first touched the first: dry! After an hour of "sunbathing", the first sheet is close to being completely dry; the second sheet is much better than the first, not completely dry; the third sheet, sloppy me grabbed the third sheet, the water dripped down at once. Oh my god! An hour's exposure didn't evaporate any of the water. I was amazed!

The next day in science class, the teacher explained to us, and I realized: it was because the paper was covered with wax paper, so that the water reduced evaporation. Just like the strange skin of the cactus, the cactus reduces the necessary evaporation so that it can survive in the desert.

Through this interesting experiment, not only let me know the cactus drought-resistant reason, and understand that life everywhere there is science, as long as they continue to experience the process of scientific inquiry, will be able to obtain scientific knowledge from it, understand the true meaning of science.

As soon as class started today, the teacher took out a stack of freshly torn strips of paper from her purse and pulled one out of it. Then he pressed the end of the strip of paper tightly to his chin. We saw it and burst out laughing. Mr. Deng said calmly, "I'll blow down and guess where the note will float?" Some said it floated down, some said it floated up, and some said they didn't know. Everyone talked and talked.

Ms. Deng waved her hand to quiet us down. I saw her press on the note, puffed up her cheeks, and blew up with all her strength. At first, the note did not move much, blew a few breaths. Just see the note shaking "ass", flat floating up. The students all shouted, "Look, flat floating up."

Mr. Deng let us take turns one by one on the stage to blow the note, some puffed up cheeks like a toad, some puffed up cheeks, up full of red, veins rippling. Some of the students to make the strength of the milk, the note lazily, not even move a little. When it was my turn, I held my breath, gathered my mouth into a circle, and then blew hard. My note was so high and proud that it shook its butt and floated up.

In the end, the teacher summarized why some students could make the note float up and some couldn't. The reason was that the airflow was coming from the middle of the mouth. The reason is that the airflow from the middle of the mouth to run out, not from the sides of the mouth to run out, we blew out the force to make the surface of the strip of paper to reduce the pressure, so the strip of paper floated up.

This experiment is really interesting, so there are so many small science in life, just that we do not know.

Teacher's comments: This is a narrative essay. The author of a complete narrative of a thing, the beginning - the process - the end, the structure is complete. But the article can start another paragraph as the beginning, the end is also missing a transition, but as a third-grade student, it is already very good.

As far as I can remember, there were many classes that I enjoyed, but one of my favorite classes was science, which increased my courage.

"Ding bell, ding bell ......" class, this class is to go to the laboratory class, we have long been prepared for the large size battery two, a wire, two light bulbs. Before this, we have learned about making light bulbs bright.

All my life, my biggest weakness is timidity, this class is to let each group to choose a person, on the stage to demonstrate his experimental process, and ultimately can make the bulb light up. The students in our group know that I am timid, but they prefer to let me go up, I have no choice but to seize the time to experiment. During the lesson, the teacher stopped halfway through. The teacher first let the first group of people up to demonstrate, this group out of our class is the first five good students, I watched their experiments, really inspired, the turn of our group, I found an assistant, need to be made under the supervision of the projector with a battery to light up the two bulbs of the experiments, I first use the positive electrode of the battery to press the end of a wire, and scissors to cut the rubber outside the wire, half of which is connected to a bulb, the other half is connected to another bulb! The other half of the other light bulb, pressed on the top of the negative pole, a try, did not light up, and tried again, hey! And did not light up, I was like a hot pot on the ants - anxious round and round, the critical moment, the teacher reminded me that: "positive and negative poles are reversed", I quickly changed over, finally the bulb lit up, the following loud applause, I was also relieved! I'm so relieved, I walked down the podium with ease.

An ordinary experimental class, but let me courageous, from a timid and fearful students, to a dare to go to the stage to do experiments, this is one of my most memorable class.

Today, I did a match dancing experiment with my mom and dad. At first, I asked curiously, "Daddy, why do matches dance?" My dad said mysteriously, "You'll find out in a minute." I followed my dad's instructions and brought in a basin of water. Dad took out a match from the matchbox, brought a bottle of glue from the table, applied a thick layer of glue on the match's ignition point, and put it into the pot. After about a minute, I said to my dad, "Dad, why isn't it moving at all?" Dad didn't say anything. Just when I felt disappointed, quasi was gone.

The matches suddenly stood up from the water, one after another, one after another, left and right to dance, I said to my dad "Look! The matches are dancing!" The match danced continuously for about 1 minute, it jumped on the surface of the water, from time to time to turn around, it is like a match with an invisible dance partner in the dance. In a short while, it was like a sleepy doll, sleeping on the water surface, and after another 5 minutes, the match was full of energy again, and continued to dance, still dancing so lovely, so joyful, so rhythmic. But in a short while it collapsed again, and after waiting a few more minutes, it would get up and dance again, and after repeating this many times, the match collapsed and never moved again.

I couldn't understand why. So I asked my mom for advice. My mom told me, "There is phosphorus in the match head, and when it comes into contact with glue, it produces a gas. The more the gas gathers, the more it will make the matches stand upright, and when the gas plays, the matches will be driven to "dance". When the gas on the outside of the match head has evaporated, the match will not move. After a while, the gas gathers again, and the match stands up and "dances" again. When all the gas has evaporated, the match can no longer dance."

This is a really interesting experiment! Not only fun, but also let me learn a lot of knowledge!

Put the water in a paper cup, and then turn the quilt upside down, the water will not flow out. You may not believe it, today, I will let you see it!

First of all, of course, the first to prepare the material: a paper cup filled with water, a basin, a few pieces of paper, the experiment began, I carefully user paper wrapped around the mouth of the cup, and then take the cup to move to the top of the basin,, and then invert the direction of the paper cup, thought it would be successful me, the result is out of my expectation - the water flow! It came out! "SORRY, SORRY, it was just a mistake!" I was busy explaining to everyone. Undeterred, I took another piece of paper and started the experiment again. But I failed again! What's going on? My classmates began to talk. Suddenly I felt wet under my hand, I raised my hand to see that there was a bit of water on the table. Wait a minute, isn't this where I just placed it! It turned out that I had been using wet paper! Doing this experiment with wet paper won't work! I changed the paper and started the experiment all over again. When I reversed the direction of the cup, a pair of surprised eyes staring at the cup, the water did not flow out, the experiment was successful!

The students asked me what was going on, I replied: "This is a small experiment to prove the existence of atmospheric pressure. Because the contact between the water and the paper cup produces atmospheric pressure, because the atmospheric pressure makes the paper sucked the paper cup, so the paper will not fall, the water will not flow out."

Look at this experiment, you believe it! In fact, everything in the world is wonderful, as long as there is a pair of good eyes, you can find a lot of amazing things!

One day, I was paying full attention to "Science for the Masses", and suddenly I was attracted to the book, which said that when you put an egg into salt water, no matter how you press down, it just sinks and floats back up. I found it a bit unbelievable: the egg was so heavy. It will only sink to the bottom of the water, how can it float to the surface? So I decided to do an experiment myself.

I prepared the materials: a cup of water, eggs, salt, can not wait to start doing the experiment. First of all, I put the egg in the water, and found that the egg did not float, it is at the bottom of the cup motionless, as if it was sucked by the iron absorption stone. I started to add salt to the water and stirred it with chopsticks, but the egg didn't move. I continued to add salt and stir. The egg slowly started to float upward, and I was so excited that I saw the "flame" of hope, but the "flame" went out and the egg sank again as it floated. What happened? I brought the book "Science for the masses" to carefully read a few times, finally, "effort does not fail", I finally found out the reason, it turned out that the water is too much. So I poured out some water, added some salt to the water, stirred for a while, the miracle appeared, the egg is like a balloon full of gas, I pressed my hand, the egg sank, and once I let go of my hand, it was like a naughty child floated up again. What is the reason for this? I couldn't figure it out. Looking at my puzzled look, my father told me the secret: "The specific gravity of water and salt water are different. The specific gravity of the egg is bigger than that of the water, so the egg will sink in the water; the reason why the egg won't sink in the salt water is that the specific gravity of the salt water is bigger than that of the egg". I suddenly realized.

This little experiment brought me an unexpected harvest, through this experiment also let me understand: the door of knowledge is hidden, only dare to explore, the courage to pursue the people can open this ideal door.

Last week in science class, the teacher instructed us to bring a few things with us when we come back to class this week: a candle, a few corn kernels and an iron spoon. This group had to have at least one of those ready.

All of us were curious about why we had to bring a few things, and we were all chattering and excited before this class. After the bell rang, the teacher entered the classroom with a smile, walked up to the podium and said to us, "Today, the teacher is going to take you to do an interesting experiment."

The teacher first showed us on the podium, she first lit the candle, and then put a few kernels of corn in a small iron spoon, and then use the hand has been erected on the top, waiting. We all watched with bated breath what would happen to the kernels of corn. After about seven or eight minutes, a student suddenly called out: "corn kernels cracked," we all gathered to see, really, one after another, several corn kernels are cracked, just like the usual effect of popcorn. It was really fun.

After that, we divided into groups to do their own experiments, we are very excited in the process of experimentation, after the experiment, there are people pick up the "test" taste, although not very tasty, but there is still some sweet flavor. Really is an interesting experiment ah.

One day in the summer vacation, I did a test of ants eating. This experiment was to test what kind of food ants like to eat. The food I needed to prepare was a little spent milk candy, a dead insect, a vegetable leaf, some wood shavings. A piece of white paper.

I first picked a piece of green vegetable leaf, scraped some wood shavings, found a little bit of melted milk candy, as for the dead insect, I first caught a grasshopper, just get it dead. And by all means get a piece of white paper 60 by 60 centimeters, put the material on the paper, to catch ants.

It was hard to catch 30 ants and put them on the paper, but they crawled around and ran to the side. I was not willing to let them go, and caught them back to continue to observe. What a group of ants that never give up, they actually ran to the side again and again. I was really angry, so I simply went to catch another large nest of ants, they were all frightened, crawling around, a mess. I thought that after a while the ants would be looking for food, and all I had to do was wait quietly. However, the ants did not appreciate it at all and still crawled to the outside of the paper. My patience is limited, I got angry, these little ants really don't know what to do, they don't appreciate my love, I have to do something hard. So I stuck a little ant on the candy, let's see what you do. The ant broke free. I put it on the sugar again, and it broke free. It fell off, I put it back on, it fell off again and put it back on. After all my tossing and turning, it finally ran out of energy, but its legs and feet were still stomping around. I was stunned and took it down.

Although the experiment did not succeed, but by the little ants never give in to the spirit of conviction.
