A: Grade 8 can do physics experiments, but they need to be accompanied. Generally speaking, in junior high school, you will be exposed to physics classes and related physics experiments, and there are also related experimental requirements, and you can do physics experiments in the eighth grade.

Summary. The simple experiment in Physics 8th grade is as follows: 1. Take two identical small beakers (150 ml), fill them with water, put beaker A on the iron frame, and put beaker B on a wooden block, so that the water surface in the two beakers is kept on the same level. 2. Insert two siphons, one long and one short, filled with water into two beakers.

The siphon is made of ordinary thin glass tubes heated and bent on an alcohol lamp. 3. Add a few drops of red ink to beaker B and stir well. And prepare the alcohol lamp on the iron stand.

4. Light the alcohol lamp to heat beaker A, and after a while, you can see that the red water in beaker B flows into beaker B continuously, and finally the two cups of water turn red. At the same time, when you touch beaker B with your hand, the water in beaker B also becomes hot, indicating that there is convection between the two cups of hot and cold water.
