In science class, right now we are learning about cell organelles. We are learning about what each organelle does to help the cell. There are several different cell parts with very important jobs to do. Each part has its own specific way and thing to do.
One part of the cell is the Nucleus. This organelle is very important to the cell because it is the "brain" of the cell. It has specific duties in order to keep the cell alive. Another part of the cell that I think is important is the ER or Endoplasmic Reticulum. I think that this part of the cell is important because it helps transport energy to different parts of the cell. These are some of the parts of a cell that I think are the most important in the cell.
Day 3: Head: 50mm Tail: 20mm Ratio: 20/50 | Day 6: Head: 55mm Tail: 30mm Ratio: 30/55 | Day 9: Head: 60mm Tail: 40mm Ratio: 40/60 | Day 13: Head: 62mm Tail: 50mm Ratio: 50/62 | Day 45: Head: 75mm Tail: 110mm Ratio: 110/75 |
Above is a chart with the growth of the baby rats each day we measured them. According to this information, the ratio of the tail lenght to the head circumference (listed above) changed each and every day the rats were measured. All in all, the tail length eventually became bigger than the head.
Although you cannot feel your cells working inside of you, there are other ways you can tell. For example, when you get hot, you can tell your cells are working because you start to sweat. When you get cold though, your body shivers to try to warm you back up in order to keep your body temperature normal. There are many more examples and ways to tell your cells are working inside you, even though you can't feel them. Even if your cells were not working, you would be able to tell. All in all, there are many ways you can tell if your cells are working or not.
Every cell inside your body has one specific job, or thing to do. For example, your nerve cells focus on sending signals to your brain, so your brain knows what is happening. Each cell also has its own way of functioning. They function the way they want and the way that they think is best. As you can see, there are many different cells with different jobs to do; and each cell does its job a certain way.
Do you look like your mom or dad? I look like my dad, but people always say that I look more like my mom. I have long browm curly hair, dark hazel eyes, and I'm tall for my age. Both of my granmothers are short, but my grandfathers are both very very tall. They are 6'0" and 6'3", while my grandmothers are 4'10" and 5'0". I am supposed to end up being 5'8" but I'm oply 5'4", and I'm twelve, so who knows if I will grow anymore.
I get my looks from both sides of my family. Personally, I think I look more like my dad, but others say I look like my mom. However, that could just be because I'm darker like her and my aunt, and I have her eyes. I'm not built like neither my mom nor my dad. I am built more like my grandfather (my mom's dad). I am pretty tall, I guess. Hopefully I still grow though. I have a long torso, but short legs. My legs are pretty defined, and you can see the muscles. All in all, I think I look like my dad more than my mom.
I do! Getting the volume of an irregular shape is actually very simple. First, you just fill either a flask, beaker, or graduated cylinder. After you've done that, you then measure how much liquid there is. Then, you insert the object you want the volume of and measure how much liquid there is now. After all these steps, you then subtract the amount before from the amount after the object was inserted. Then, you have the volume of an irregular object! It's just
In science, we just finished reviewing how to find averages. We made a paper frog and a card-stock frog and made them jump 10 times, then we measured how far they jumped. After that, we took all of the measurements and found the average. This week in science, we just reviewed how to find the length of an object by using centimeters, millimeters, meters, & inches. We are now reviewing how to find the volume of an object. Also, we are making estimates. All in all, we have accomplished many things in the few weeks we have been in school.
