Reflection
Yesterday in UOI, I learned about the disasters around the world. I know more about the causes and effects of the disasters. We all discuss together and Mr. Perico will question the people who didn't recite. We all are getting more knowledge. Earth changes because because of natural disasters too and it is the dangerous cause of Earth. Example of natural disasters are; typhoon, tsunami, tornado, flood, earthquakes, volcanoes etc.

Symmetry
After watching the video, I learned that symmetry has in architecture, nature and art. It is kind of interesting to me because I love nature and I love to find out about it. The video is good for grade 4 students because the way it explains can make students understand. Symmetry is in real life because people build things using symmetry. We learned about symmetry because our dream might be be to be a builder, artist etc.

My reading on Erosion and Weathering
I didn't rad about erosion and weathering. I have some questions that I love to know. They are;
1) What is the meaning of weathering and erosion?
2) What can weathering effects us?
3) Why is there erosion?

The answers are;
1) Weathering is a break down of rocks, solids etc.
Erosion is form the nature like landslide, avalanche etc.
2) Weathering can affect us to die.
3) Theres erosion because of gravity caused by nature.
The causes of this changes because of nature, pollutions etc.

Science Investigation Time
Our experiment is about how do fires turns off. It is kind of interesting because the fire turns off without water or blowing. It's because of carbon-dioxide and I learned thatr carbon-dioxide puts off fire.
My favorite experiment is Rizqi's and Hafizh's experiment because their experiment is "Color Change". First they put qa half of water and put food color green. Then, they put a toothpick and bleach. It turns to yellow. The thing that I was confused is that what is the toothpic for?

Reflection
Yesterday in English, we typed our persuasive essay in Microsoft Publisher. When my work is done, I saved it but its not responding. So I started it again. I had a hard time in making the pictures smaller because its too big and I can't see the things that I typed in there.
In UOI, we explained our experiment. Our experiment is about the effect of carbon-dioxide to a burning candle. It is about carbon-dioxide affect a candle. First you need to put two candles in a tray and one of them is covered and the other not covered. And I learned that carbon-dioxide puts of fire. The experiment that I like is Rizqi's and Hafizh's experiment because they told us how to change color. I like it because its so interesting.
In Math, We all continued our activity with our buddies. We sre done with our work and Mr. Perico called us to continue at home, then, Mr. Perico gave us another activity about Area and Perimeter. I did it with Sallyna and we finished it.
