Chromosomes, 1 - 22

Chromosomes: 1 - 22

If you didn't know every human has 23 pairs of Chromosomes, in total we have 46. Here is an image of how we solved and placed each chromosome in each section! 

Task description:

Today in room 4 Genomics we were to place each chromosome from numbers 1 - 22. Each pair were to be Red and blue with words/numbers written on each chromosome. This task was quite challenging as it was hard finding and matching the right chromosomes. Although it was challenging I definitely found something I never knew before, Thanks to Doctor Terry I had so much fun as it also made many of us come together and work as a team. Now I know more about chromosomes and the exact amount we have!     

Hope you enjoy and that you learn something off this post, I definitely did!  

Chromosomes - 5th December 2019 

Who Dunnit?

Who dunnit?

Today in room 4 we are solving a crime due to the scene of someone breaking in & stealing something which hadn't been found by the owners or anyone, during the investigation we found bits and pieces of bloody cloths which was covered in blood. The window was violently smashed and the man had vanished in under 2 minutes before the investigators arrived.

Suspect 1: AB + 
Suspect 2: B
Suspect 3: A+
Suspect 4: 0 -

Although the suspects had different blood types all we were needed to find was A+. Due to the blood stains on the bloody cloth we had found the perfect match which came out A positive. The suspect was perfectly matched to suspect 3. Here are the images of us testing our suspect's blood!

Suspect 3: Positive - 4th December 2019!   

Dna - note taking!

Dna - note taking!

Today Room 4 watched a short video about cells and how they’re connected. Below this
introduction is my what I’ve been taking notes of. Learning more about cells and how they’re

connected was incredibly interesting. I really hope you enjoy! 

  

How is Dna, chromosomes and gene connected? Today we will be talking about how Dna,
chromosomes and genes relate. 

Our body is made up of hundreds and thousands of cells. Cells are only seen under a microscope. 

Humans have 23 pairs of chromosomes. Chromosomes have different sorts of information about
dna.

 Dna is made up of 4 basis (AKA) 4 different things. A,G,C,T. Dna is in the chromosome, the
chromosome is in the nucleus, and the nucleus is in the cell. 

The reason why Dna is shaped as a ladder is because…

A always joins with T  and G always joins with C

When a sequence of three pairs come together they create a word, then when we add more
words together we then create a chapter which is called gene.  

Gene’s are like chapters in a book. More than one or two genes is what creates our chromosome.
Chromosome is what lives in the nucleus.

Protein base letters:

Codons = words

Gene = Chapter

Chromosome = Book

Science Experiment

Science Experiment!

Aim: see onion cells on a microscope

Hypothesis:
I think the 100x magnification we’ll be able to see what’s about to happen!

Equipment: 
Microscope Onion
Slide
Cover slip
Tweezers 
Blue dye - Blue stain

Method:
Our very first step started off with using a slide, after that we got ourselves a pair of tweezers and one onion, using the tweezers and onion we were to peel a thin layer of onion and gently placed it onto the slide, after placing the thin layer of onion onto the slide we were to pour a few drops of saline on top and add a bit of blue stain. The last step was to add a cover slip as it’ll help to make our vision more clear to see.

Observation: 
On the 10x microscope we were able to see the basic shape of the cell.
On the 40x microscope we were able to see a closer version of the segmented area.
On the 100x microscope we were only able to see the blue stain but from what our vision was the colour was purple.

Label the parts of a cell - Inquiry

What’s inside a cell?

SAY IT - NAME IT - LABEL IT

NUCLEUS: Nucleus is the brain of the cell. It tells you what type of cell it will be and when it will decide to divide.

RIBOSOMES: Ribosomes is what makes the proteins. The cell can create new structures from the ribosomes protein.  

CHROMOSOME: It’s the item that carries our dna. 

GOLGI BODIES: Post office? Is what transports molecules around the entire cell.

MITACHONDRION: The powerhouse of the cell. They take in food and turn into energy cellular respiration.  

ENDOPLASMIC RETICULUM: Transportation that collect and take the molecules to where they are needed to go.

About Organelles

All living things contain a variety of different cells. Cells are the main structure that living things are based on. The cell membrane is a thin layer that separates what goes in and out. The cell wall is incredibly tough and holds its shape. Cell walls are what let them stand tall. Tiny organ that play a different role in the cell. It gets rid of waste, reproduce and repairs. The organelles float in cytoplasm.

The Tree Of Life

WALT: Learn about the origin and tree of life

Today Room 4 is learning the living things that currently exist and extinct on our planet. On this image of the tree of life lays sea animals, creatures, land animals, flowers and more. After finding the rightful places for these animals/creatures we thought it'll be the greatest time to reveal and find the information of the origin of life. We are currently learning the origin of life which is super exciting and amazing as it really links on to what we are learning at the moment. The tree of life means everything, if you didn't know the tree of life created all living things by making one single cell organism. In a cell is nucleus, chromosome, DNA and of course Gene. A cell covers 2/3 of water inside your body which means your body is 2/3 of your whole entire body. Animals reproduce overtime and children are born with different traits. If it turns to be a positive trait it's able to live longer, if it's born with bad traits it would unfortunately die. 

Our topic this term is how are all living organisms connected? The tree of life is currently what the whole team is learning and is what most of us students are wanting to learn. I love that we are able to learn more or start learning about genomics as it tells us about, how we are related to different animals, how are all molecules connected and how the tree of life was made. Darwin was famous for it's well known knowledge for the tree of life. I can't wait to see what is to come and hope to find out more of what and when the tree of life was first made. 

Empanada - Inquiry

EMPANADA'S

Today in inquiry Room 4 will be trying the one and only Empanada's. Empanada's are known for being a traditional dish from Argentina located in South America. Empanada's have the ingredients of Sweet Paprika, Spice - Mild, Capsicum, Mince, Onion, Sugar and Flavours of Spice. The overall outcome of this dish is made by using Puff - Pastry filled with a bit of meat and of course healthy vegetables. 

The smelt of it:

Pizza, Pastry, Sausage Roll, Smokey Flavour, Strong Capsicum, Little sweet and spicy, Strong pastry smell and Powerful Puffed Mince.

The looks of it:

Sausage Roll, Golden Crisp, Darker edges, Triangular corners, Mince Pie, Crisped Dumpling, Brown looking Red colours, Spiced Red, Roll.

The taste of it:

Meaty, Chunky Mince, Sweet but a bit spicy, Crispy edges, Very sweet raisins, Vegetable Pie, Soft Bites, Strong Flavours from the spices and mince, Very delicious.

The sound of it:

Crispy, Chunky bites, Smooth + Soft.

The feeling of it:

Hard Bumps, Runny ingredients, Crumbly - Soft - Smooth, Chunks of pieces. 

Overall I would personally say that Mrs Stone did really well with her cooking as this turned out of being a really delicious dish. Thank you Mrs Stone for the cooked delicious meal.  

Europe - Italy

Task Description:

Today Room 4 and I were to write and list down a few things about some countries in Europe. The place I have decided to choose was Italy as my facts are mainly based on the Romans and its people. The images include the different but most popular places in Europe - Italy. Europe is also the place where the special and amazing languages there are which are Spanish and French.
