Blogging as an instrument to learn

           
             Nowadays, the blogging is very useful because blogging is a discussion or informational site published on the World Wide Web and consisting of discrete entries ("posts") typically displayed in reverse chronological order. By this we can use now blogging for learning such topics and to communicate with our classmates and our teacher,to give them information or share your ideas by the use of blogging.This may be an instrument to post an topic or quiz and sometime in blog we can save all the important documents that can help us to study and know what are the information post by our classmate or new task that we should finish.

            As a education student blog is very important to us because this can help us to communicate to tour teachers and class using blog site. Your insights or thoughts you want to share, you can also put it in the blog. In our Educational technology 2 we can use different websites and other program by the use of computer but this blog site is different to other website because you can create on your own design and you has a rights to put what you want in the dashboard of your blog, any ideas and topic you wanted to share. Also, blog site can help students to learn more and answer more on what you have written on your blog because they can visit it and explore more about the blog that you made that is educational and easy to understand by everyone. An example of blog site is were you can look for details on what you are looking for and this can be a big help even each of the people can create a blog this is very helpful to us students.

            Using blog is enjoyable but you should consider those people who will read your blog, if they understand it or not and if they can get information to your blog. Using blogging is important to us because in our new era, we don't know that computer will be the one by means of communication and students can learn on it. In how many years the blog is still their you can visit and read again those important post that you had that you can use in learning. Lastly we can use this blog and share our knowledge how to create and use blog for them to use it when they having this kind of computer or if they will get information trough their blog that I or they made.

Digestive System

Digestive System

 
      The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract).

Parts of the Digestive System

*Mouth

The mouth is the beginning of the digestive tract; and, in fact, digestion starts here when taking the first bite of food. Chewing breaks the food into pieces that are more easily    
  digested.

 

*Esophagus

Located in your throat near your trachea (windpipe), the esophagus receives food from your mouth when you swallow.

 

*Stomach

The stomach is a hollow organ, or "container," that holds food while it is being mixed with enzymes that continue the process of breaking down food into a usable form. Cells in the lining of the stomach secrete a strong acid and powerful enzymes that are responsible for the breakdown process.

 

 

 

 *Small intestine

Made up of three segments — the duodenum, jejunum, and ileum — the small intestine is a 22-foot long muscular tube that breaks down food using enzymes released by the pancreas and bile from the liver. 

 *Pancreas
The pancreas secretes digestive enzymes into the duodenum, the first segment of the small intestine. These enzymes break down protein, fats, and carbohydrates. The pancreas also makes insulin, secreting it directly into the bloodstream. Insulin is the chief hormone for metabolizing sugar.

 

*Liver

The liver has multiple functions, but its main function within the digestive system is to process the nutrients absorbed from the small intestine. 

*Gallbladder

The gallbladder stores and concentrates bile, and then releases it into the duodenum to help absorb and digest fats.

 

 

 

*Colon (large intestine)

The colon is a 6-foot long muscular tube that connects the small intestine to the rectum. The large intestine is made up of the cecum, the ascending (right) colon, the transverse (across) colon, the descending (left) colon, and the sigmoid colon, which connects to the rectum. The appendix is a small tube attached to the cecum. The large intestine is a highly specialized organ that is responsible for processing waste so that emptying the bowels is easy and convenient.

 

*Rectum

The rectum (Latin for "straight") is an 8-inch chamber that connects the colon to the anus. It is the rectum's job to receive stool from the colon, to let the person know that there is stool to be evacuated, and to hold the stool until evacuation happens. 

*Anus

The anus is the last part of the digestive tract. It is a 2-inch long canal consisting of the pelvic floor muscles and the two anal sphincters (internal and external).

Lesson Plan : Digestive System

Digestive System Lesson Plan:

Grade Levels: 6-8, 9-12

        In this digestive system lesson plan which is adaptable for grades 6-12, students use a free online science interactive to learn about the organs and organ substructures of the human digestive system. Students work in teams to identify the digestive system’s parts and structures, and drag and drop them to the correct position within the body to build a complete system. Students will also attempt case studies where a problem within the system must be linked to the structure affected.

Lesson Plan Common Core State Standards Alignments

Students will:

1. Work collaboratively to identify the parts and structures of the human digestive system.
2. Use an online interactive to build a complete digestive system and explore how the parts work together.
3. Apply problem solving skills to various case studies, linking variables to the organ structure affected.

Materials:

• Interactive whiteboard
• Computer with internet access
• Four small dry erase boards, iPad/tablets, or large sheets of papers

Preparation:

        This lesson plan features an interactive activity in which students learn about the human digestive system. Build-A-Body is a drag and drop interactive in which players choose organs from the organ tray and drag and drop them in their correct position within the body to build the digestive system. The interactive also includes case studies where a problem within the system must be linked to the structure affected. To prepare for this lesson, preview the Digestive System movie and the Build-A-Body interactive, and plan how to adapt the resources for your students' needs.

Lesson Procedure:

1. Play the Digestive System movie to review what students have already learned about the digestive system.


2. Project the Build-A-Body interactive for the class to see. Divide the class into four groups, and tell students they will have the chance to compete in teams to assemble a human digestive system. The game will be played in two sections: identifying parts and structures within the system, and attempting case studies where a problem with the system must be linked to the structure affected.


3. Read the text to the left of the illustration, then choose one part of the digestive system that's listed on the right. Challenge students to work with their team to define the part, and write a definition on a small dry erase board, iPad/tablet, or even a sheet of paper. On your signal, have each team hold up their definition for you to read.


4. Click on the body part and read the definition that's now displayed on the left. Compare the definitions to those that students generated. For quicker game play, the teacher can determine whether each team's definition is accurate enough to receive points (3 points for an excellent answer, 2 points for a good answer, 1 point for partially correct response, or 0 points for an inaccurate response.) For more in-depth game play, display all the team's answers at the front of the room and have the class analyze them together. You could rank the responses from most thorough and accurate to least, awarding the top-rated response 3 points, the second top-rated response 2 points, etc., with the fourth-place response earning no points. Keep track of each team's points on the board.


5. After discussing each part of the digestive system, explain that you will be introducing case studies where a problem within the body must be linked to the structure affected. Click on one of the case studies at the top of the screen, and have each team work together to determine combinations to try. Each team should write down their strategy. Have one player from each team take turns coming up to the interactive whiteboard and entering their solution, and award points based on the the level of success each strategy produces. Alternatively (and to save time), you could assign a different variable to each group.


6. Encourage students to reflect on the structures they explored through the interactive. You may want students to conduct further research about one of the problems raised in the case studies, and make additional real-world connections.

Extension Activity:

Students can explore and build the digestive system as well as other systems within the human body in BrainPOP's Guts and Bolts game. Be sure to check out all of our Health Games and Science Games for more learning resources.
