Animal and Plant cells

  Hello The internet! It's SuperSara with another blog about cells!!! Yay! Ok so this time we are going to talk about the difference between animal cells and plant cells. Even though they are both cells (duh!) there are still many differences between the two.There will be a video at the end (by yours truly) Ok,  I'll stop talking now and get to the point.

  Plant cells. The cell of a plant, obviously, but there's more to it than that. Plant cells have parts an animal cell doesn't have. First of all it has a cell wall. A cell wall is another layer of protection and is basically just a similarity to the cell membrane.

  Second of all, a plant cell has a much larger vacuole than an animal cell.

Vacuole of a plant cell, much bigger than an animal cell's, right?

   Another difference is that Plant cells have a chloroplast. Chloroplasts have something called chlorophyll.
Chlorophyll is what makes leaves (and whatever else) green. In the fall, the chlorophyll goes into hybernation, which makes the leaves turn red. In the winter, the whole plant(leaf) dies, and so they fall off the trees.

   Plant cells make their own food using photosynthesis. Animal cells have to get their own food. 

Heres the Video!

Hope you had fun!

Meet Cellerium

 Hey guys! SuperSara here with another blog about cells. A-Tom's still really sick and doctors say he has the flu for life. But, I talked to A-Tom and he told me he has a friend named Cellerium. Cellerium is gonna be teaching all you guys about cells today, and SuperSara will go sit on the couch and watch television. Ok, here's Cellerium.

  Hey, my name is Cellerium. I am a cell scientist, and I'm going to take you guys on a journey of cells! Here we go!

Everything living thing in the world is made up of cells. Cells are very important because they keep us alive. Once you die, your cells die too. There are two basic types of cells; plant and animal.

Here are some vocabulary words:

• Nucleus:  Round and dark. Is "the brain" of the cell.

• Cytoplasm: What the nucleus floats in. Basically it's just this jelly blob that takes up most of the room in the cell.

• Cell membrane: Protects the cell. Let's good stuff in and out of the cell. Doesn't let bad stuff come in and reminds me of a castle wall.

• Mitochondria: The powerhouse of the cell. Gives the cell energy, and are rice shaped.

• Lysosomes: The cleanup crew. Lysosomes are small structures involved with the digestive system.

• Vacuole: The storage bins. They store food, water, and watse. They pump extra water out of the cell.

• Ribosomes: Small round structures in the cytoplasm that make proteins.

A Eukaryote cell, the ones that  we are made up of

Next we are going to have a video by SuperSara about cells.

Well... That's all for today! SuperSara fell asleep on the couch, but she specifically told me to tell you this: SuperSaraSuperBye!!!!

The Trip

  Hey SuperSara here coming back from an awesome field trip! So almost every kid from 4th-Kenneth at my school went to Titusville, FL to see the shuttle launch. We left on Monday and drove for 10 hours! On Tuesday, we went to the Kennedy Space Center.

We saw an IMAX movie called "Hubble 3D", went on some tours, and rode the space simulator. It was very fun. As we were coming out of the gift shop (where I got a cool t-shirt, picture below) that we learned the shuttle launch was delayed ANOTHER day.

 Ok, so originally the shuttle was supposed to launch on Monday. It got delayed from Monday to Tuesday because of electrical problems. I got delayed from Tuesday to Wednesday because politicians asked (Tuesday was voting day). It got delayed from Wednesday to Thursday because of electrical problems. Then it got delayed from Thursday to Friday because of bad weather. FINALLY it got delayed from Friday to Monday because of a fuel leak.

 


We were all pretty mad when we found out about the shuttle because we had driven to Florida for nothing. We were all tired from riding on the bus from 9 pm to 7 am the previous night. Straight after that we got our luggage in our rooms, and went straight to the space center at about 9 am. We were very tired and it was really hot and we had a walk everywhere and had to wait in line for almost an hour in the gift shop. The news that the shuttle was delayed, we didn't get to see it, and we had to go back to the space center the next day didn't really get us in a better mood.

That night, we went to Pizza Hut for dinner and were all smart about what to get (we were paying). We eventually found out that it was on our teachers, so it was for nothing. We went back to the hotel, and I got an okay sleep.

Cocoa Beach

  The next day we went to Cocoa beach and had a really fun time. At first we were going to go back to the hotel to get out of our wet, sandy clothes, so we got all wet and went out in the ocean. Then, we weren't going back to the hotel. We were all cranky and sandy. It was 84 degrees that day, and we had to sit in the sun. I had a bag of chips for lunch. It was good, then bad.

My eyes are closed, but who cares?

  We drove to Kennedy Space Center, and we all got paired in groups. I saw another IMAX movie called "Space Station 3D". Then we went to this big wall with a bunch of tiles that had the names of people who had lost their lives to space. There was a donation box, and we each donated  about a dollar. We rode the Simulator Ride again, and I had alot of fun now that I wasn't scared. We went to see some more things, and then met in front of the gift shop. We had had a long day, and I was starving. We drove back to the hotel.

  After having a spaghetti dinner, we w outside and played freeze tag. The rules were that Mrs. Crimminger was it and once you were tagged, no one could un-freeze you. Me and practically everyone else lied down in the shadiest part so Mrs. Crimminger couldn't see us. She found all of us eventually and while I was running away I tripped. I got up and I had this roaring pain in my ankle and I saw Mrs. Crimminger and Taylor, one of the 5th graders, on the ground with me. I was told that Mrs. Crimminger feel on my ankle. We went back to the room.

  Mrs. Crimminger and Miss Sara, the headmaster of our school, came into our room at about 9 pm. They told us that NASA was having a meeting at 5 in the morning about the launch. If it was still going on, we would go see it. If it got delayed, we would leave 8 am.

  I got woken up at 7 am by Mrs. Crimminger. We were told that it was delayed. We got dressed, headed for the bus, and left. Our trip was officially over.

  This trip was good, and I had alot of fun! I was glad my parents let me go, and I hope you had a good time learning about my experience. SuperSaraSuperBye!!!
