Today is Thursday. There's a lab session. Class, the teacher came in to tell us an interesting experiment, paper pot boiling water. Everyone did not believe that paper is not the most afraid of fire, how can we boil water? The teacher brought the paper pot and put it on the fire. After a while, the water began to smoke, and the teacher asked us to have a look, but we still didn't understand? The teacher assigned us homework, looked up all kinds of information to find out what was going on. Students, do you know?
Today, I saw the first lesson of the first semester, and I felt it was very good. My favorite is the scientific experiment of hatching chicks without shell. First put the yolk in the eggshell into the film, then put the film in a basin, and finally put the basin into the thermostat. The thermostat must reach 27 to 28 degrees so that the chicks hatch after 21 days. I am very interested in scientific experiments. My dream is to be a great scientist when I grow up.
Today, I did an interesting experiment at home. I think a box of pins will come out slowly when they are put in the water, but I put one box, two boxes and three boxes, but none of them come out. I think this problem must be checked on the mobile phone. I checked it. It turns out that the pins are hollow. As long as they become smoke in the water, the pressure of the water will be reduced, and the water will not come out slowly. I'm really proud of myself for finding this problem. I think as long as I find out a problem carefully, I can get the right result.
