Cell Organelles (9/19-9/23)

http://www.aboutthemcat.org/images/biology/animal-cell.png

Summary:

This week I learned that all of the cell organelles are important to the cell and that there is not only one organelle that is important. Each organelle does something good, but there is also always a negative side of each organelle. All of the organelles depend on each other to be able to do their job. In other words, one organelle would not be able to keep the body alive without the other organelle.

Lets take a cell membrane, for example. The cell membrane depends on the endoplasmic reticulum to transport proteins for the cell. As another example, the cell membrane works with the cell wall to allow molecules and other substances to enter and leave the cell.

 Each organelle has a job that it needs to do for the cell, and some other organelles to work. For example, the cell membranes job is to protect all of the organelles that are inside of the cell. Without the cell membrane, the other organelles would not be safe, so they could not do their jobs.

Every organelle can do something bad when things go wrong. There is not just one organelle that carries diseases. 

 For example, the cell membrane can have a disease called cystic fibrosis. This disease causes for the cell to produce less water. When this happens in the lungs, it makes your saliva become really thick which makes it really hard to breathe.

 As another example, the mitochondria causes a disease called the mitochondrial disease. This happens when the mitochondria fails to do its job. Over time, this causes less and less energy that is being generated in the cell. This can lead to injuries in the cell, and even cell death.

 Some organelles (such as a cell wall or chloroplast) are only found in a plant cell. Other organelles (such as lysosomes) are only found in animal cells. Most of the other organelles (such as the cell membrane and the nucleus) are found in both animal and plant cells. Sometimes the same roll is played by different organelles in the different kind of cell. For example, lysosomes are the animal cells "garbage", but in plant cells, the vacuole does the same job as the lysosomes. In an animal cell, the vacuole stores waste and nutrients that the cell can later use.

SP6: Constructing Explanations and designing solutions:

My group and I constructed an explanation of how the cell membrane works with other organelles, and the diseases that it can cause. We constructed our explanations and solutions as we made our script for the video about our chosen organelle. We also learned that there is not just one organelle that is the "best," they all depend on each other to do their jobs.

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 vibrate, mak

The Food Chain (10/26-10/30)

This is an example of a land food chain http://www.sheppardsoftware.com/content/animals/kidscorner/foodchain/foodchain2.htm Summary: This week in class we started to learn about the food chain. We watched a video about the food chain, and then we had to answer a few questions. First you need to know that food chains always start with plants and end with animals. But remember, humans are animals. Humans are usually at the top of the food chain. But that does not means that they are always at the top, what if a lion ate the human! Then the lion would be at the top of the food chain. There are different types of food chains. If you want to see a full list then go to this website: http://examples.yourdictionary.com/examples-of-food-chains.html . In the video they talked about the ocean food chain. The ocean food chain is a food chain that happens in the ocean. Here is an example of an ocean food chain: phytoplankton (tiny little plants), get eaten by zooplankton (tiny animals

African Forest Elephants (2/5-2/9)

African forest elephants range from 2.5 - 3 meters in height, weighing from 50-200 pounds. Their color is usually brown and grey, and even though other coloring is possible, it is very rare. They live for about 60-70 years, which is quite a lot compared to some other forest animals. The African Forest Elephant lives in Central and Southern Africa, traveling through the forests and grasslands searching for food and water.  Why Endangered: The populations of these Forest Elephants is decreasing because of illegal poaching. The poachers kill the elephants for their ivory tusks to sell. They are also decreasing because of habitat destruction such as deforestation, which results in less food and shelter, which they need to survive. According to defen
