Change Journal

Hello! Hotty,
in UOI, we study about the meaning of physical and chemical change. We found out from Mr.Perico that physical change is the change that can seen the change but, the substent will not change. For example, a water that has been put in the fridge and became ice. But, the ice still can be water if we melt the ice through the sunlight or heatness. Chemical change is, a change that can be seen but, the substent will change unlike physical change. We tried some experiments in the labotary room like, putting brown sugar in the water and the smell changed and the colour changed. It is physical change because the substent not change. That is what I learned for today, bye-bye!
