Science experiment evaporated in kindergarten
The following are some small experiments on evaporating that are suitable for kindergarten: 1. ** Add water and observe the evaporating ** - [Experiment Materials: Alcohol Lamp, Beaker, Water] - ** Experimental steps **: First light the alcohol lamp, fill the beaker with water, and then heat the beaker on the alcohol lamp. After heating it up, he guided the child to observe the changes in the water in the beaker. - [Experimental principle: When water is heated, water vapor will be produced. The phenomenon of water vapor running up is called "evaporating."] This was because when water was heated, the molecular movement intensified, and the liquid water turned into gaseous water vapor, and this process of turning from liquid to gaseous was called evaporating. 2. ** Observing the evaporating in daily life ** - [Experimental steps: Guide the child to think about the phenomenon of evaporating seen in daily life, such as the water on the ground slowly drying after the rain, or the phenomenon of wet clothes drying after drying.] This was because the sun's rays caused water to heat up. 70% of the Earth's surface was covered by water. When water was heated, it changed its form and turned into invisible water vapor. This process was called evaporating. Three-quarters of the water vapor in the atmosphere comes from the ocean, and the rest comes from rivers, lakes, and moist land. 3. ** Bubble Evasion Experiment (extended understanding)** - [Experiment Materials: Water, dishwashing liquid, glue, straw, gloves] - ** Experimental steps **: First, prepare a mixed solution of water and dishwashing liquid in a ratio of 3:1. Dip a straw into the solution and blow out bubbles (this kind of bubble is easy to break). Then, mix the glue and the mixed solution in a ratio of 1:2. Dip the straw into the solution and blow out bubbles. Wear gloves to touch the bubbles. - [Experiment Principle: The bubbles in Step 1 will explode due to the water evaporating.] This involved the thin film formed by water on the surface of the bubble. The bubble was easy to break due to the condensation of water, which also reflected the phenomenon of condensation. After adding glue, it would become very sticky, and the moisture would not evaporate easily. The strength of the bubble membrane would increase, so it could jump on the back of our hands.

The camera takes pictures
At present, there was a patent that could hide the iPhone's front FaceTime camera and front flash in the earpiece, making the iPhone more simple, but there was no information about the actual effect of the earpiece camera. Regarding the camera in the earpiece, in theory, the camera in the earpiece had a similar principle to the ordinary front camera when taking pictures. It needed to obtain permission from the phone system to activate the hardware to take pictures. When taking a photo, the light entered the camera in the earpiece. The light sensor in the camera converted the light into a digital signal, which was then processed by the image signal processor inside the phone to form a photo. However, the resolution, image quality, and focusing ability of the earpiece camera of different devices may vary greatly. For example, the front camera of some devices had low resolution, so the imaging effect might be average and the noise was serious. The front camera of the Vivo S19 used a 50-million-pel lens, and the imaging effect was better. At present, the technology related to the earpiece camera was not very popular, and the maturity of different devices was not consistent. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
