Organelles (9/28-10/1)





Summary:
Website Link
This week we were learning about organelles, cells, tissues, and organs. I learned that it all starts with the organelle and ends with the organisms. The organelles make friends (work together)in a cell. Then the cell makes friends (works together with other cells) and forms a tissue. Then the tissues come together and form an organ. Them all of the organs come together to make the organ system. Then the organ systems work together to make an organism.

The organelles work together but they have their own jobs. For example: The chloroplast gets the sugars from the sun and the mitochondria makes it into energy for the cell. Cells that have the same job work together to make a certain tissue. You have skin cells form skin tissues, blood cells form blood tissues, etc.

When tissues get into groups together, they make organs. For example, a brain is an   organ so it is made out of brain tissues. Your heart is made out of heart tissues. It is the same with all of the other organs.

Organs work together in groups which is called an organ system. For example, the stomach, small and large intestines, and many more make up the digestive system. These organs work together to digest food. Another example: The Circulatory system has some of these organs: The heart that pumps the blood, and the veins and the arteries take the blood and they deliver it to other organs.

As you can see all of these parts work together to help the organism. If all  parts are working correctly, then you are very healthy. If one of these parts went wrong, you could get sick. Now we all know that every part in your body is very important. I                                 can't wait to learn more about the organs and systems in class with Miss J.

Structure of the Periodic Table - 9/25-9/29

https://image.slidesharecdn.com/theperiodictable-110223090122-phpapp01/95/the-periodic-table-7-728.jpg?cb=1298451775 Summary: This week, we have been learning about how the periodic table is arranged and the different patterns that are in the rows  and columns. In the periodic table, the rows are called periods. Along the rows, the elements are organized by atomic number (the number of protons.) The rows also have the same energy level or the number of electrons. For example, in the first row, all of the elements' atoms have one energy level, and so on.The atomic mass is the number of neutrons plus the number of protons. The atomic mass can be a decimal, and it is ordered increasingly. The columns in the periodic table are called groups or families. Each family has a name. For example, group one is composed of alkali metals which is the family with Lithium, Sodium, and more. Each group also has the same number of outer, or valence electrons. The elements in group one ...

Musical Instruments and Sound- Weekly Blog (3/11-3/15)

Sound Energy - Musical Instruments by SolPass Summary We understand how sound is produced, and how sound waves can travel through different mediums, but how do musical instruments produce sound? There are hundreds of instruments in the world, producing various pitches, tones, and chords. There are three main types of instruments: wind, percussion, and string. The sound is produced differently based on the type of instrument. The first type of instrument is a string instrument. In a string instrument, the sound is created from the vibration of strings. For example, when you play guitar, you pull on the strings. As the strings vibrate, the air molecules start vibrating as well, producing sound. The next type of instruments are wind and brass instruments and are made when we blow sound into them. The shape and position of the instrument affect the overall tone and pitch. The most common kind of wind instrument is a reed instrument. Blowing on the reed causes it to vib...

Energy Transformations - Weekly Blog (1/28-2/1)

Types of Energy  by  Solar Schools Summary: You've probably heard the quote by Albert Einstein, "Energy cannot be created or destroyed, it can only be changed from one form to another." But what are the forms of energy? There are six general energy forms: chemical, mechanical, thermal, light, electrical, and nuclear. Any form of energy can be converted into another form. There are many examples of energy transformations that happen in our everyday lives. The first energy form is chemical energy. Chemical energy is a form of potential energy and is stored in chemical substances. An example of chemical energy is gasoline that is used to power a car. The next form of energy is mechanical energy. Mechanical energy is energy released by a moving object. For example, mechanical energy is the energy that causes a soccer ball to move when kicked. Another form of energy is thermal energy and is associated with the motion of molecules. This means that it is caused by f...
