Mechanical And Chemical Erosion

Mechanical erosion is not doing erosion naturally, so instead of the air eroding rock, machines break the rocks to transform them into little ones.






Mechanical erosion





Chemical erosion is when the minerals that make up the rock are changed.

Michel's year reflection

My Year In Grade Five...

My year in Grade Five helped me a lot in growth and learning. Two years ago I used to study in a small school in Brazil; but when I moved, I knew CAC was different, it looked big and fun and anything you might ask for. The school helped me with a lot of things that my other school would not be able to do. In grade five; I experienced a lot of fun things while learning, and my teacher, Mrs. Kasal was the best, she is super kind and funny and she taught my classmates and I in the best way possible, Grade five was the best!

Reading...

In reading, I can say that I developed a LOT. In fourth grade, it was hard for me to read for a long time and stay focused, but during grade five I developed a lot and now I am able to read and focus for hours. Mrs. Kasal is always teaching and helping us in case we are stuck somewhere,  and classmates can help each other with the work, I guess that's why Mrs. Kasal most of the time lets us work in groups.

Writing...

In writing, I developed in my grammar, the way I write; and I learned new methods and new vocabulary. During grade five I had a lot of fun writing fantasy, informational, narrative and other topics. Mrs. Kasal is always teaching us new methods and always keeping us awake being funny and kind; writing can be really annoying sometimes, but we always have fun learning so we always have fun writing.

Math...

Math is something I really improved on. In grade four I was average in mathematics; but now I got the third best score in M.A.P tests, but that was only possible because Mrs. Kasal taught us and helped us in the best way possible; even though we had the annoying Eureka Math, this year math was really fun

Science...

In my opinion I think that science was really fun this year, we learned a lot and did a lot of fun things in the science lab. My favorite thing in science this year was the adaptation unit; it was so fun and we got to learn more about animal's and plant's adaptations, we even did a science fair based on it; We had partners, my partner was Pranay and we chose our project to be about the Arctic Tundra.

Social Studies...

In social studies I had a lot of fun learning about the aztecs and the history of the U.S, I did not know about many ancient civilizations, but during this year I got to learn a lot of things about one of them and in grade six I will learn more.

Citizenship...

I do not know what citizenship means, but I think it means being a good friend, classmate and student; if it is I improved a lot on it, because this year I made really special friends, they were: Nico, Ian, Pranay, and Momo.

Most Challenging...

The most challenging part of grade five, in my opinion was when we had to work together in the grade five thing in the beginning of the year, it was so challenging, but it was really fun, and when we played baboomba, my team lost, but I had a lot of fun. 

Most Enjoyable...

The most enjoyable part of grade five was the way 5K learned together, always having fun and 

playing and all the other fun things

Most Proud Of...

I am most proud of 5K because we had a lot of fun together and we accepted to learn together, we became great friends.

Most Growth...

I grew a lot in all subjects and categories, but most of all I grew in friendship, I made a lot of friends; best friends.

Parent responses...

1. I see it as growing a lot, failing many times but never giving up, always going, improving, and finally mastering something.

2. I had a lot of fun in the thing that we did in the beginning of the year (unity day), where we did a lot of activities that required a lot of teamwork and, and I struggled a lot in multiple projects, sometimes there was not enough information, sometimes it was not valid information etc. etc.

3. I think I could improve a lot in handing assignments in time, because sometimes I forget to turn them in or I get them late, so that's something I need to improve.

Evidence...

Show Goal Sheets.

This year I showed initiative when I convinced my friends to do something.

Slow process erosion and rapid process erosion

Slow process erosion is a type of erosion that happens slowly, for example; air erosion, air erosion happens really slowly, a rock only gets a little damaged when a lot of dust or sand that the air carries hits the rock.






Eroded rock.




Rapid Process erosion is a kind of erosion that happens really fast, like an avalanche, or a landslide, an earthquake.







Avalanche.

Thesis statement

Because people are spending more time online, watching movies, and playing games, I believe this leads to less focused people and kids that repeat the grade.

QUESTIONS

• How many students repeat the grade every year in the US?
• What are the benefits of film makers and video game makers?
• How many people die yearly in car accidents because of driving and looking at the phone at the same time?

4 corner activity reflection

All of the opinions of everyone were good, two things that  that surprise me were that Jimmy thought that boys were better than girls in science, I do not agree with Jimmy, because that was an individual question; something else that surprised me was YoungSeo's rage.

wind erosion experiment.

Virtual Reality

     The virtual reality was very real, the grand canyon was amazing, the words that the person said in the trailer were very convincing, and the fall were awesome, the natural space is so cool.
 The devils pool doesn't look that much "dare-deviling".  But the views were very cool, and they were very beautiful and  COOL.

experiment 3: flood

 Question: How does the amount of water that flows through a stream table affect erosion + deposition?

Hypothesis: The water deposits a lot more sand.

Materials: Fine sand, rough sand, clay, 3 cups of water, ruler, stream table, beaker.

Procedure:1. mix fine and rough sand with clay; 2. make the sand flat; 3. put the water in the beaker; 4. wait for the results

Observation: the thing was very fast, almost nothing happened, but the water "flooded" the land

       Conclusion: I have to admit,  it wasn't very interesting.

Wadi Degla field trip

      The bus ride was not so long, I couldn't wait until we got there. When I hopped down the bus, I saw it, a big valley, slopes spreading both sides, I was amazed.

      I honestly thought the walk to the spot that we were going to eat was not so far away, but it was. After the safety talk we set off, I stayed around the middle of the group.

      We sat on a place with no shade, but it was windy, so I didn't sweat. Dr. Bill started talking, I didn't know how he exceeded in making the whole fifth grade be quiet.

      Apparently we were sitting on what used to be an ocean floor thousands of years ago, a giant meat -eating whale called, ahhh... I don't remember it's name, but there also swimmed the Megalodon, my favorite species of sharks, but it's extinct, sadly. 😢.

When Dr.Bill finished talking, I went exploring a little-, and I realized that there were holes in the walls, I thought I could climb to the first hole. As I did so I forgot that we were not allowed to do that, so a parent made climb down. Th field trip was a lot of fun.


Dr. Bill explaining stuff.

Experiment four: Water engineer

Question: what happens to the tissue when water flows and hits it?


Hypothesis: the tissue rips.

Materials: Fine sand, rough sand, clay, 3 cups of water, ruler, stream table, beaker, tissue, tape.


Procedure:
1. mix fine and rough sand with clay;
2. make the sand flat;
3. put the water in the beaker;
4. wait for the results


Observation: It made a huge River 0:20, 0:40 the water just went under the tissue. 1:34 The tissue got wet all over. 6:00 It went crazy (The tissue fell, the tapes are all around)

Video: https://youtu.be/6SWW01g-CtU


Conclusion: The hypothesis failed, but the experiment was a lot of fun, the water did not rip the tissue, but wet the tissue all over.

experiment 2: deposition

 Question: What happens to the land that gets eroded?

Hypothesis: The land follows the river downstream until the hole.

Materials:Fine sand, rough sand, clay, 3 cups of water, ruler, stream table, beaker.

Procedure:1. mix fine and rough sand with clay; 2. make the sand flat; 3. put the water in the beaker; 4. wait for the results

Observation:20 seconds: water is making a river. 52 seconds: Making a fast river. 1 minute 23 seconds: going down really fast. 1 minute 40 seconds: water is at the end of the river. 1min 50 sec it creates a new land at the end of the river. 3 min 30 sec: it made a huge land. and it made canyon. 5 min 10 sec it made a huge huge huge land made out of the sand in the canyon at the end of the river. ? min, the water is starting to fall. 5 min 50 sec it made a river on a new land. 6 min 50 sec: it stopped.

       Conclusion: our experiment worked, the land that the water passed through gets eroded and ends up at the end of the river.

APL QUOTE

 "Don't raise your voice, improve your argument
~Desmond Tutu
      I think the quote means that when you discuss something  with someone else, you should not scream or shout, you should only speak with a calm assertive  voice. I wonder who is Desmond Tutu, because he sounds wise. I think the quote is good, because it would help  you through life and it helps people not to get mad at you.

Experiment one: water erosion

 Question: What happens to land when water flows over it?

Hypothesis: I think water erosion happens, when water erodes earth and carries it down the river.

Materials: Fine sand, rough sand, clay, 3 cups of water, ruler, stream table, beaker.

Procedure: 1. mix fine and rough sand with clay; 2. make the sand flat; 3. put the water in the beaker; 4. wait for the results

Observation: 0:35 forming a little pond; 1:25 the water is starting to go down; 2:30 the water is making a river; 4:00 the water is starting to spit out; 5:00 some of the water fell from the stream table; 6:30 the water stopped.

      

 Conclusion: the water eroded the sand/clay and made a river, but our experiment failed and we need to do better next time.

science EQ

EQ: I think that our earth is shaped like this because of how it changed and changed over the millions of years, because of landslides, earthquakes and other events. It is how the earth is, and we should like it , but prevent anything that could happen to harm us. We have devices to warn us and that is good enough, because the earth is always changing, events and events happen, so we must know how to deal with them, even though some of them are our fault.

Science

Erosion: Erosion happens when the wind the water or other natural forces hit the earth and makes it fall off.

Flood: When a lot of water comes into land and takes everything with it.


Weathering: A natural process that shapes the earth and rocks.


Deforestation: when people cut down or burn forests, on purpose or not.


Earht's plates: earth's outer layer is made from large things called plates, all of our land and water lie on the plates.


Landslides: When earth from mountain sides fall and cause huge destruction.


Glaciers: When big moving islands of ice are in the ocean


Rapid process erosion: Erosion that happens very fast, like  when a earthquake strikes and some land disappears.


Slow process erosion: When wind erosion hits a rock, a very slow progress happens until the rock is shaped like something else.


Tsunami: When an earthquake happens in the middle of the ocean, very soon a big, giant, humongous wave hits the shore, that is a tsunami.


Earthquake: When the ground shakes and big rocks under the ground move.


Debris: rubbish, trash.


Topsoil: Surface land that farmers usually plant on, or where plants grow most of their root.


Sediment: Stones and sand that are deposited by wind water or ice.


Volcanoes: More than one volcano.


Canyon: A deep valley with steep sides and usually a little river flowing in between


Plateau: A long flat space in high land


Dune: A hill of sand piled by the wind


Delta:A triangle shaped piece of land made by deposits of mud or sand in the bank of a river


valley: An area of lowland between mountains.

Michel the wise

My name is Michel, My favorite topic as a scientist is mostly about animals, because if they die, the world as we know it would end, so I would study them, and then save them. I like baseball and soccer, my favorite kind of science this year is animal adaptations, I like to know about how animals survive and create strange living things.

Learning science is very important, because you know how to make cool experiments and know how our earth is now and how to make it better. I would want to learn how to do chemistry, because there are a lot of experiments to do and it sounds fun.  If I were to be a scientist I would be a chemistry scientist or an inventor.

shark endangered or dangerous

My reflection
My book was about sharks, I really liked my book and I learned  a lot while writing it, as I was writing I tried to think about my audience, I hope you are satisfied. I enjoyed writing to you and it was the best I could do.
