Hello everyone, this time I went to the Hisense Science and Technology Museum in Qingdao. There are 4 floors on the first floor. The first floor is the history of Hisense and the Science Enlightenment Hall on the first floor. , the Science Enlightenment Hall on the first floor is also divided into a transportation area and a water science hall. The entire second floor is a Science Enlightenment Hall, including mirror maze, abyss and other places. The third floor is the Science Discovery Hall, which contains magical reversed water droplets and an air tunnel that can send balloons up by themselves. The fourth floor is the Nature Exploration Hall, which is divided into six areas: desert, plain, grassland, rainforest, ocean, and polar regions. Each area introduces the characteristics of its own area.
We started from the fourth floor and went down. The reason is that people generally look from the bottom up. We can avoid the flow of people from the fourth floor and it is safer. On the fourth floor, we looked from dry to wet. First we went to the desert area. Several animals were displayed in the desert area. First we looked at the ant.
This is a lot of ants crawling around in this small box. The reason why this ant is called ant is because it looks like It is tempting to arch its back, hence the name of this ant. (You can see the big picture below)
This is the fossil between the walkway from the desert animal area to the desert scenery simulation area. The first one is a fish fossil. It is a fish that appeared very early because it has four fins. The second piece is an ancient eel with a long body and is very flexible. The third piece is a trabedodocus. When this trabedocus died, It should have died lying down. The fourth piece was a pterosaur. This pterosaur fell to the ground and was buried in the soil and turned into a fossil. The last piece was also a fish, but there were only two.
The first picture is of two little hedgehogs. Because they have not grown up yet, the thorns on their bodies are not yet long. They have been indoors for a long time without seeing the light, and their colors are not that bright. Deep, the second picture shows several rabbits. The rabbits' fur are intertwined in black and white, and they are nibbling on some leaves. The third picture is of four slightly larger hamsters, also in black and white. One of them is nibbling on corn leaves. The fourth picture is They are two little hamsters. One of them is drinking water from his mouth, which is very cute.
This picture shows five very small microorganisms. The first picture is amoeba. Amoeba can parasitize in the human body and harm human health. The second picture is It is Paramecium. Paramecium is the largest biological microorganism, with a size of about 0.1 to 0.3 mm. The third picture is Escherichia coli, which has many tentacles. Once Escherichia coli enters the large intestine, it will cause diarrhea and other intestinal infections. , the fourth picture is yeast, the yogurt we usually drink is fermented by yeast, and the fifth picture is Chlamydomonas, a kind of algae, named Chlamydomonas because its shape resembles a piece of clothing.
? These sixteen pictures are all specimens, among which animals include jellyfish, small rays, conches, crabs, etc. Each one is placed in a large glass jar and soaked in formalin. , plants include algae, vegetables, etc. The jellyfish displayed here is a relatively small jellyfish, and there are many other varieties of jellyfish.
This picture shows me and my classmates doing an experiment on building an arch bridge. First, we need to place the building blocks in the corresponding positions according to the serial numbers, and then stand up a movable board at the bottom. , and then slowly lift the base plate. If the bridge does not collapse, then remove the base plate to see if the arch bridge still exists. My classmates and I failed several times.
? This is a simulation of prying the earth that my classmates and I did together. Everyone pulled the rope down with their hands to tilt the middle beam to one side, thereby levering the "earth". Archimedes once said: "If you can give me a fulcrum and a lever long enough, I will move the entire earth." This is the famous Archimedes Principle, because this principle is Archimedes's principle. De discovered it, so this principle is named after him.
This is how my classmates and I work together to make the ball pass through all the rings when it pops up. First, adjust the angle of the ejection surface below the track, and then according to the order of the rings, make all the rings pass through. To make the ball pass through, we first thought of the parabola, so we arranged the rings in the order of short on both sides and high in the middle. After adjusting the angle, we launched the ball. In the end, none of them passed through. We adjusted the order and angle several times. Only passed through two rings. Afterwards I remembered that the best angle is the one that can pass through the highest ring.
Okay, these are the notes of my classmate and I’s visit to the Hisense Science Discovery Center. See you next time.
