An Interesting Experiment Essay Example Hurry! Fast! Who s quick to get extra points!!!!

I was curious to know if putting too much water or too little water would make mung beans sprout faster, so I did an experiment a few days ago to test it. I first took two plastic boxes, then paper towels and water, and also brought two mung bean seeds, I first put the paper towels in the two boxes, then put 50 drops of water in one box, and 80 drops of water in the other box, and then I put the two mung bean seeds in the two boxes, and wrote the number, No. 1 with more water, No. 2 with less water, and finally, I put the box on the south-facing balcony. Do all this, my heart is sweet, and I can know the result immediately.

I also guessed that the group that thought the mung beans that were put in more water would germinate faster. I stood quietly on the balcony and waited patiently for this moment to come. I waited for about 2 hours and found that the seeds in box 1 were much larger, while the seeds in box 2 had barely changed.

I waited for another 3 hours or so, and I found that the seed skin in box 1 was broken, and the seed in box 2 was only much larger. I was secretly happy and continued to wait for the moment when the seeds would sprout. About another 3 hours later, I looked at it again and found that bean No. 1 had a foot sticking out, while bean No. 2 was only broken.

I thought: I'll know the results in a little while! I waited for 2 hours and I saw the seeds germinate in the box with a lot of water, I let the seeds germinate faster, and I cried out with joy:

I guessed it, I made it! Yikes! This mung bean germination experiment has benefited me a lot.

Today, when I came to my father's office out of breath after playing ball, my father took out a lot of strange things and said to me, "Li Jian, do you want me to do an interesting experiment for you?" I said

Okay! But what do you use to do it? Dad pointed to the pile of things in his hand and said

That's it! I said, "Huh?

No way! How can it be? What experiments are you going to do?

Eating fire experiment," my father said with a wicked smile.

Then he took out a bottle of alcohol, and then he took out a peeled pear, and soaked it in alcohol, and then he took a candle and lit it with fire, and then he took out the pear, which had been soaked in alcohol, and then he took out the pear, which had been soaked in alcohol, and lit it with a candle, and then, the important moment came, and a miracle happened! Daddy swallowed the still flame-breathing Sydney!! I yelled, "Wow!

Dad, are you dying? Aren't you afraid? Oh my god!

Don't let anything happen to you! "I thought with prayer and with urgency. After a few minutes, it was amazing!

Dad was actually fine, and he chewed happily, and said that it was delicious, it was really strange! I asked my dad, "Dad, aren't you afraid?"

Could it be that you have cultivated a vajra mouth that is not afraid of fire? I said in amazement. Dad told me:

It's nothing, as long as you put the pear in your mouth and keep your mouth closed and don't breathe, that's it, how about it, do you want to try it?. I said, "Yes!"

Dad repeated what he had just done, and then he brought me the burning pear and said, "Wait a minute, you can eat it when I tell you to eat it, and you can chew it when I tell you to chew it, remember!" I looked at Sydney, who was still burning on fire, and said with fear

Good. So, I took the pear, "eat," Dad said, I immediately put the pear in my mouth, and after a few minutes, Dad said, "Chew."

So, I ate it, and ah! It's really delicious! And I didn't feel any pain at all, I thought it was really strange, so I asked my father, and my father said:

Everyone knows that fire is burned by air, because when we eat it, we immediately shut up and stop breathing, then there is no air in our mouth, and the fire is naturally extinguished, so it's okay! ”

Yes! It turns out that there are such wonderful experiments in the world!

Today, we waited for the teacher to come and give us a science lesson. After a while, the teacher came in, and she cleared her throat and said to us, "Let's do an experiment today, fellow old students.

Immediately, the students cheered because this was our first time doing the experiment. We quietly followed the teacher to the science lab, and it was very large, the size of two classrooms. I saw that the experimental equipment was already waiting for us on the table.

The teacher showed us first, and she skillfully picked it up. I saw that the students were watching intently, staring at every action made by the teacher. The teacher said after doing it:

When turning on the alcohol lamp, be sure to pay attention, otherwise it will happen**. When the students heard this, they were all terrified. "Next, please do it once in a group.

The teacher said. Everyone in our group was very scared, afraid that the alcohol lamp would blow him up, and he didn't dare to take the lead. The experimental materials in front of my eyes are:

Iron stand, alcohol lamp, test tube clamp, glass, glass sheet, match. I brought the old iron frame to me. Pour about 500 ml of water into a glass, place a mesh on the iron stand, and place the glass on top of the mesh.

Then use a test tube clamp to clamp the glass piece. At this point, it's time to light the alcohol lamp. What to do?

What to do? My heart is like fifteen buckets of water--- seven up and eight down. But I can't back down!

That's what my heart thinks. I finally decided to insist, I carefully and meticulously swiped the match, at this time, I saw that the people in our group were far away from me, and I knew that they were afraid that they would **. "Please, don't be so cowardly," I called out to them.

Even though I said that, I was actually scared too. I slowly lit the alcohol lamp from the bottom up. I carefully placed it underneath the wire mesh.

On top of which I put a slice of glass on top of the glass. At this point, we wait for the rain to form.

Teacher Xu walked into the classroom with a smile on his face and took out a bottle of mineral water, a plastic bucket, a bag of salt and an egg as if by magic. Teacher Xu said, "Let's do an experiment today.

The second class was in class, and we all couldn't wait for the teacher to do the experiment. I saw that the teacher poured half of the mineral water into the cup, and Hong Yinjing then put the egg in the water, and the egg sank to the bottom of the water at once, as if sleeping lazily. How do you make the eggs float?

The classmates began to talk cautiously, and finally decided to put some salt. Teacher Xu put some salt, and then took Hu Yanlong's chopsticks to stir the salt, but the egg still did not float, and the classmates said that there was too little salt. Mr. Xu himself felt that the salt was too little, so he put a little more, but the egg still did not float, added a little salt, stirred it with chopsticks a few times, and finally the egg floated, and the experiment was successful.

Some students didn't believe it, so Mr. Xu asked the students to gently press the eggs to the bottom of the water with their hands, and then let go of the eggs, and sure enough, the eggs floated again. Seeing this, I remembered the Dead Sea, and some people committed suicide by jumping into the sea without thinking about it, and immediately floated up when they jumped into the Dead Sea. This is a mystery that I have never been able to solve, and until now I know the reason why I jumped into the Dead Sea and floated again, that is, there is too much salt in the water, and the buoyancy is very strong, so of course people will float when they fall.

Doing this experiment today has added some gains to me.
