For the parents：
We looked at the heaviness of liquids, found the pressures they exert and now we have arrived at buoyancy. Next week, we will turn towards air pressure.
After being very attentive, in the middle of the week, many students got bored by a few students discussing bizarre ideas. Therefore I established a voting scheme to find the major opinion to follow up in class, while those students in favour of minor ideas would need to search for experimental proof first.
This first week of the physics main lesson in G8, I also got sick. However, I am already getting well again.
