Science- Things I have Learned

Out the 7 last week of our science class. I have learned 4 main things in science and there are :

The Skeleton
Our skeleton consists of 206 bones. However, when we were an infant you had as many as 350 as some of the bones fuse together as you grow. More than half of your 206 is found in the hands and feet. The largest bone in your body is the femur (thigh bone). The femur connects to the tibia and fibula (shin bones). Our humerus (funny bone) connects the radius and ulna (forearm bone). Our shoulder blade is called the scapula and our collar bone is known as the clavicle.  Our cranium is known as the skull. Our fingers and toes are called phalanges. The mandible (jaw). The smallest is found in the ear and called the hammer, anvil, and stirrup.

The joints
Function
-Cartilage-reduces friction and acts as a shock absorber.
-Synovial fluid-Keeps the cartilage slippery and lubricated. 
-Synovial membrane-Produced synovial fluid and hold it in place.
-Ligament- Hold bones together and stop them coming apart.

The muscle

The muscle a band or bundle of fibrous tissue in a human or animal body that has the ability to contract, producing movement in or maintaining the position of parts of the body. Muscle is attached to bones by strong tendons. When a muscle contract, it pulls on the bone, and the bone can move if it is part of a joint. Triceps are the back of the upper arm. Biceps are the front of the upper arm. Hamstring muscle at the back of the upper leg. Quadriceps muscle at the front of upper leg. Gastronomic calf muscle back of the lower leg. Tibialis Anterior muscle at the front of the lower leg.

The Blood
The Blood is made up of four main components-plasma, red blood cells, white blood cell, and platelets. Plasma carrying carbon dioxide to your lungs. The white blood cell fights infection and disease. Platelets are tiny fragments of cells. They are responsible for making blood clot when you get a cut in your skin. Red blood cells contain a chemical that carries oxygen around your blood cells make up about 45% of the blood. The chemical messenger is called the hormones.

Social Studies - Child solider

Child Solider

In my social studies class we have been learning about slavery. In particular Child slavery, child trafficking and child soldiers around the world.  I chose to research the topic child soldiers in Somalia. More information are in the slide below:

Maths

What does it mean to be a good mathematician?*Help people in going  maths problem.*Great skill in maths.*You can become good at maths simply by dedication. *Take time each day to practice maths until the concepts start to click for you. * Most people  can improve at maths with some extra hard work.*Should always prove your answer and show your work.*Should take their time and think about it first.*Use different strategies to solve your problem.*Should always check their work.*Make sure your answer makes sense.
*Ask question/opinion  from teacher and student .
*Double check your work. 
*One reason why people who learn more mathematics earn more is because doing maths makes you smarter and more productive. According to Clancy Blair, a professor of psychology at NYU, the act of performing mathematical calculations improves reasoning, problem-solving skills, behaviour, and the ability to self-regulate. 

Human Right

The top 5 human right:

*Freedom

*School

*Marriage

*Religion

*Law

Corona virus

Corona virus

1.What is the corona virus?

Corona viruses are a family of viruses known for containing strains that cause potentially deadly diseases in mammals and birds. In humans they're typically spread via airborne droplets of fluid produced by infected individuals.  Some rare but notable strains, including Wuhan corona virus (2019), and those responsible for severe acute respiratory syndrome  and Middle East respiratory syndrome.

2.Why are you interested in it?
Corona virus is a world wide problem . The virus has infected more than 14,200 people in mainland China, with a further 100 cases reported from 23 other countries. Although the disease is mostly confined to China, where each of its provinces and territories have reported infections, corona virus has reached as far as the US, France, Germany, Australia, Japan, Canada and South Korea, the United Arab Emirates, the UK and Finland. At least 304 people have died in China plus one person outside of China .

3.How does the news impact on you , your community , the environment or the world?
The loss of jobs. Family member loss. People are scared around the world. People will be afraid to eat foods in china. Some people will be racism to china people.  

4.What does that corona virus make you think about, worry about, or want to take action about?
Cover your mouth and nose with a tissue when cough or sneeze. Put your used tissue in the rubbish bin . Wash and dry your hands often, especially after coughing or sneezing use soap. Stay away from others if you're sick. 

Bones

Bones
what are bones?A bone is a rigid organ that constitutes part of the vertebrate skeleton in animals. Bones protect the various organs of the body, produce red and white blood cells, store minerals, provide structure and support for the body, and enable mobility.

How does our body make bone ? Bones begin life as cartilage. As the young baby develops in the mother's womb, the skeletal system becomes organised into a framework of cartilage. Before birth, there is a certain amount of hardening of the limb bones to allow the animal to stand shortly after delivery. However, the greater part of the skeleton is cartilage at birth. After birth, hardening of all parts of the skeleton begins. This process continues throughout life until, in old age, very little cartilage is left and the bones are old and brittle. The process of hardening cartilage into bone is called ossification.

How do they grow/repair? Throughout life, bone is constantly being replaced in the process of bone remodelling. In this process, osteoclasts resorb bone, and osteoblasts make newbone to replace it. Bone remodelling shapes the skeleton, repairs tiny flaws in bones, and helps maintain mineral homeostasis in the blood.
