1st: Reflection
In UOI, Mr. Perico used his laptop to show us the information about Natural Disaster. We wrote the observable change, the cause, and the effect. Now, we have known about natural disaster. I wanted to research about it so I can learn more.

2nd: Symmetry
After watching the video about symmetry, I know how to use it in architecture, nature, and arts. Architecture can built a building which has symmetrical line, in arts we can draw a place or living things that has symmetrical lines, and nature we can put a flower which has a symmetrical lines too. Symmetry is a picture or drawing that has the same side. We can fold it horizontally and vertically.

“I learn symmetry so I can know what the use of symmetry is.”

“It can be used in folding and drawing exact side.”

“I need to study about symmetry so I can now what is the used.”

“We can see symmetry in all around us.”

3rd: Reading about “Erosion and Whether”
From what I’ve read, I learned that erosion is displacement of solids (sediment, soil, rock and other particles). It is current as a wind, water, or ice by downward or down-slope movement in response to gravity.
In whether it is, weathering is the decomposition of rocks, soils and their minerals through direct contact with the planet's atmosphere. Weathering occurs in situ, or "with no movement", and thus should not to be confused with erosion, which involves the movement and disintegration of rocks and minerals by agents such as water, ice, wind, and gravity.
I read the information yesterday but I still can remember it. I will re-reading so I can remember more of this information.
I’m interested to know in:
· What is the difference between whethering and erotion.
4th: Group Working (experiment)
In the experiment time, I learnt something in Rizqi’s group. I learnt that the colour can changed by putting the bleach, toothpick, and green food colour. The first is putting green food colour and it became colour green. Second, they put a bleach and a toothpick it became colour yellow. I didn’t know why they use toothpick. I think it has something related to it.
My experiment can’t be present because I were not ready that time.
