Fossils

Fossils are something left from a plant or an animal that lived long time ago that have turned into a rock. Many of fossils are things that now is extinct. Extinct means a living thing’s kind is no longer alive today. For example, dinosaurs are extinct.
Fossils are form when a living things dies. It gets covered by sediment. For example, like mud, sand, soil, or clay. After a long time, soft pats decompose. Decompose means it breaks down. Then, the harder parts stay. After that, more layers of sediments pile up. So, it gets heavier as more sediments pile on. Since it got heavy, sediments presses down, so it creates a lot of pressure. Then, the lower layers turn into rocks. Water can sip through and create minerals. After many years, layers of rock slowly wash away. So then, fossils can be found. But sometimes, the living creatures can form into fossils in other ways. For example, there can be prints on rocks, get frozen in an ice, or get trapped in a tree sap. Fossils can give us clues about what happened or what was it like long time ago.
We made our own fossils. First, we had to put some clay at the bottom of a cup. Then, we made a print with a shell on the clay. After few days, we pour a little bit of liquid in that cup. After another few days, it got hard. So, we took out our fossils. But mine had broke, so I had to do it again. Next time I do this experiment, I will be very careful.
I learned from this fossil unit, that fossils can form in different ways, that some body parts from a fossil can give clues like what did that thing ate, what kind of place it live and so on. This fossil unit taught me a lot of things.

This is my fossil!

Chinese New Year Holiday

During Chinese New Year holiday, my family went to Hong Kong two times. The first time, we went hiking on Dragon’s Back (a mountain in Hong Kong), but it rained. I wasn’t sad about it since I didn’t want to hike. So we after we came down, we went to Times Square (Which is in Hong Kong) and ate in Pizza Express, bought a mechanical color pencil, and my mom and my sister shopped while me and my dad waited for them. When I was was waiting for my mom and my sister and waiting for the food in Pizza Express, I was using our “Family” phone to download some new apps and trying them. The second time our family went to Hong Kong, we went to Times Square again and watched Moana (a movie), bought two clothes for me and for my sister, ate in School Food for lunch, ate in Goobne for dinner, and went to Hysan Place (a place in Hong Kong) and shopped more. When I was waiting for food and my mom and my sister this time, I had brought my iPad with me. So I just watched some YouTube videos. It was very fun on both days. I like going to Hong Kong when it doesn’t get too tiring. I also like my new things I bought in Hong Kong. The mechanical color pencils, a pink pen, a purple pen, two clothes, three Hi-chews, and a notebook…
