     There are many organelles in a cell. I will tell you about 3 cell parts and describe what they are and what they do. First, I will tell you about ribosomes. Second, the mitochondria. And last, the cell membrane.
    First, is the Ribosomes. Ribosomes are really small. They are th smallest organelle. Even though Ribosomes are quite small, protein is made in the Ribosome. You can find ribosomes in the cytoplasm or attached to the endoplasmic reticulums wall. Second, is the Mitochondria. Mitochondria breaks down food to release energy. The mitochondria also makes ATP. Third, is the cell membrane. The cell membrane is flexible and thin. It is full of holes. It also controls what comes in and out of the cell. It is located along the edges of the cell. 
      In conclusion, I talked about the ribosome, mitochondria, and the cell membrane. I really enjoyed learning the cell parts because we got to do edible cells which I think is very fun. I think that we should do more edible cell projects because it teaches us responsibility.

The growth of baby rats

     Did you know that rats grow and develop differently? The growth of baby rats is different then ours. Yes, it is true. Baby rats. . . well I shouldn't say babies. . . When rats get bigger mostly all of their body parts get bigger, unlike us. Well you might be wondering . . a lot of our body parts grow too. Yes, but not all only most. As rats grow their heads, tails, arms, feet, and legs get bigger or longer too. Rats can climb up things really fast and like to exercise a lot. 
    In one of our science classrooms, we measure rats and find their mass. I can say the rats have gotten big. . .  and I mean HUGE ! They are so big, I don't even like to them. This is the growth of baby rats

Learning Science !

   In Science, we learned may wonderful things. First of all we learned about the safety of science. We know that you have to wear your safety goggles or glasses at all times! If you don't wear them we can get a zero. It is very important to wear them because if your partner accidently makes something explode it won't get into your eye because the goggles have side panels. They are also shatter resistant. We also got to find the volume of different size boxes. Volume is multiplying the length times width times height. Volume is really easy for me because multiplying is easy for me. We also learned what different types of science tools were called like beaker, test tubes, hot plate, flask and many more.
        Another thing we learned about was the shower and the eye flush. We learned that the eye flush has little tiny holes and a lid to it so no dust specks get into it. To activate the eye flush, you simply push the green paddle back. The shower is a bit different but easy, all you do is pull the triangle down and lots of water comes down. If its really bad you might have to take off your clothes. Science to me is very fun and interesting because you get to do fun experiments! Although we haven't done any yet, I know we will do some fun ones!
