There are many organelles in a cell, and all of them have specific roles. Some organelles are ribosomes, endoplasmic reticulum, and lysosomes. All of these organelles are important to the cell. The ribosomes is one of the smallest organelles. The importance of ribosomes is that they provide protien, which is why they are found all over the cell. Most of the time they are around the rough ER. The endoplasmic reticulum is classified into 2 groups: soft and rough. The soft ER is not surrounded by ribosomes. The ER is very important to the cell because it delivers the ribosomes in and out of the cell. For some reason, lysosomes is my favorite organelle. The lysosomes are also important cells because they get rid of waste and old, dying cells. I think that is my favorite because I think of it as a superhero. 
     There is also another important organelle, although I'm not sure if it really is one, but it is the cell membrane. The cell membrane is like the gate entrance to the cell. It controls what goes in and out of the cell. It is made of phosolipids. The outside of the phosolipid likes water, but the inside does not. Which is why it is difficult for certain materials to get through. I think of all these cell organelles as a cell city. 
      When the baby rat is first born, it goes through many changes in its life. When a baby rat is first born, it has no fur and it is blind; therefore, its mother is really needed. After a week or so, the baby's eyes are open. After another week, the baby is able to play wildly. And after four weeks, it is officially weaned and it has some fur. 
     The growth of the baby rat changes over time. To see if it has grown, you have to measure from its head all the way to its tail, and you also measure its weight. By doing that, you can see how much has the baby grown. My science class hasn't really done this because we don't have baby rats. But I have gone to Mr. Kriste's classroom and play with his baby rats. I saw them when they were first born. All the babies were sleeping and their eyes weren't open. But after 5 or 6 weeks, I went back to visit them. They had fur on them and they were playing wildly. I was amazed by how fast the baby rats grew from just being small tiny babies.
     So as you've heard, the first quarter has ended and now we are on to the second quarter. I truly did enjoy my first quarter here at Computech; I learned many things. Some things I learned took place in science class. I learned many new things in that class and I'm glad I did. We did many activities in the 1st quarter. One of the interesting activities we did was bubble gum chewing. I think that was the most interesting activity we did in the first quarter.
     What is bubble gum chewing? Well, it's exactly as it's said. We chewed gum in class for 10 minutes, but stopping every two minutes. The purpose of the activity was to see if mass of the gum would increase or decrease in the 10 minutes that it is being chewed. We used a triple beam scale to measure the mass of the gum. It turns out the gum was decreasing every two minutes that we had to stop and check. During that activity, it was my first time using a triple beam scale. I'm glad I know how to use it because I know that it will be used a lot through out the year in science class. This activity was a good experience, and I hope we get to do more interesting activites like these in the next 3 quarters, including this one. 
    How do you know if your cells are working if you cannot feel the cellular activity that is going on inside your body? Well, that is a pretty simple question. You can not feel cells moving around in your body. But a way to know that your cells are working is that you are alive and healthy. The cells keep you alive and most cells prevent you from getting sick. 
     Another way of knowing that your cells is work that your body is functioning correctly and nothing odd is really happening. Such as one day, all of a sudden, you start throwing up, your head is dizzy, and your stomach really hurts. You probably aren't getting enough nutrients and you need more energy by eating. I think you can figure out if your cells are working or not by pretty obvious things or maybe just having regular check-ups with your doctor. 
     A majority of people say I look like my father, some people say I look like my mom, and some say I look exactly like my older brother and sister. How is this possible? How do I look so similar to all them? Well, I have notice the appearance of  me and my family. My physical features and traits are made up from the genetics of my whole family. So I can say, my family is literally apart of me.  
     I can say I have my dad's eyebrows, eyes and face structure. My nose and lips look similar to my mom's, my eyes are also similar to my sister's, and I look exactly like my brother. Everyone in my family has black hair, including me. Older people, such as my mom's and dad's friends say I look like my dad a lot, but also a little bit of my mom. My brother's friends call me Little Kerry, which is my brother's name, because we are look so alike. It is very rare that people say I look my sister. Everybody in my family is about 5'7 or shorter. Overall, I think I look very much like my dad and brother. 
     I think I got my personality and attitude from both of my parents. When they were younger, they were very intelligent so the intelligence got passed down to me of course! I get very mad fast, and I have noticed that my mom does too, so I'm pretty sure I got it from her.  I have a lot traits that are similar to my parents and my siblings. I'm really blessed to be apart of a beautiful and awesome family!
    It is pretty simple to find out the volume of a solid shape But do you ever wonder how to get the volume of irregular objects, such as a rock? How will you be able to figure out the volume of that? Well, there's a technique called the "displacement technique" that will help you find the volume of an irregular object. 
     When we performed this concept in science class, we started by estimating the volume of that object. Then, we filled a graduated cylinder with water. Then we wrote down the original volume of the water. We placed the object into the cylinder, and the volume of the water should increased (but it didn't always.) The last step was to subtract the volume of the water before the object was put in it from the the volume with the object in it. That is how we got the volume of an  irregular object. 
    What I am currently learning about in science class is knowing how to measure in centimeters, meters, inches, etc. I think there's really not anything amazingly interesting about this concept. It's like practice for when we perform experiments that involve measuring and such. When we first measured objects around the classroom with a ruler, it was super easy for me, but it's always good to review what you already know.
     We are also learning how to round decimals to the nearest tenth, hundreths, etc. This concept was also like a review for me. I have not forgot how to round from all those years in elementary when I learned it. Decimals are usually involved when we measure things. 
     Yesterday, we learned how to find the volume of an object. It is also another easy concept for me. We measured objects around the classroom, wrote down the length, width, and height, and plugged in the formula. Basically, what we are learning about in science right now is mostly review. I can't wait until we perform actual experiments.
