 Digestive system; Sixth grade science

Did you know that the digestive progress doesn’t start in the stomach? Or did you know your body uses two types of digestions? During the 5th week of home school, I’ve been learning about the digestive system, and I’ve been longing to share these wacky and informative facts. I’ve gotten this information from 180 days of science of sixth grade and everything you need to know to ace science. 

What is a digestive system?: 

The digestive system takes and breaks down food, collects nutrients that was in the food and expels the leftover out of the body. The digestive system starts from the mouth and ends at the large intestine. Our body uses two types of digestion. The first is mechanical and the second is chemical digestion. Mechanical digestion is when your body physically breaks down food (like what the stomach does for example). Chemical digestion is when your body breaks down food with chemical reaction, or acids in your body (The stomach uses chemical digestion too!) 

How it works

The digestion system starts at the mouth, were you chew the food you ate. While you chew, salvia is released from salivary glands which forms the food into a clumpy ball. When you swallow, the ball goes done a tube called an esophagus where the food gets pushed down int the stomach. Here is where the interesting part happens. When the ball reaches the strong organ, the ball gets broken down into smaller chunks. After its broken down, the chunks turns into an acid called chyme.  Then, the chyme makes its way to the small intestines, where a juice called bile breaks up fat. Bile comes from the liver and pancreas. While the bile does its job, the pancreas releases a juice that breaks down fats and proteins using chemical reactions. Nutrients gets absorbed into bloodstreams. All of this happen in the duodenum, which is where most of the digestion system takes place. Then the chyme travels to the large intestine. At this point, all the water that was in the chyme gets absorbed. The leftover that didn’t get digested turns into waste. The whole system takes about 40 hours in total to finish at the anus. (The anus is the last part of the digestive system station)

Conclusion:

As you can see, the digestive system should be one of the most fascinating systems in the human world. Who knew eating some chips can make your body work so hard?

Coding with Python ; Sixth grade computer science ; Homeschool  Its been almost 2 weeks since April has started. The weather is heating up and flowers are beginning to bloom. Spring has arrived and I am very pleased. This week for home schooling, computer science was the most interesting subject I took (after math, we were learning geometry) so I decided to write about what I learned.  *Most of these information is from “coding for kids python” and “Everything you need to know about computer science and coding in one big fat notebook”.* Python:  Python is an easy and most widely used programming language. It can be used for creating codes, making projects and designing websites. Python is written in an Integrated Development Environment Program (IDE for short), a program programmers can use to type and edit code and to create Python programs. The IDLE (Integrated Development and Learning Environment) is the program that comes with python when you install it. The IDLE has ...

 New York Metropolitan Museum of Art The Metropolitan museum of Art, located in 5th avenue, is one of the worlds largest art museums in the world. It is the largest art museum in the Western Hemisphere.  On Friday August 12th, I went to the Met museum with my parents. I liked that the museum had a parking garage, and it was next to central park. If you are a New York State resident, the price you pay for tickets are up to you. Since our family lives on Long Island, we only paid 5 dollars. But tickets are usually $30 for adults and $17 for students. Kids under 12 enter for free. To find out more, you can visit their website  https://www.metmuseum.org/visit/plan-your-visit The museum has over 2 million artworks, so it is impossible to see them all in one day. We only visited 4 different galleries.  Map of Metropolitan Museum second floor (Created by Met) Circles are the place we visited ‘The Death of Socrates’ by Jacques Louis David located in the European paintin...
