Prisms

This term we are looking at measurement. This week we have been looking at prisms in particular. Yesterday we looked to how to work out the volume of different prisms, and what is the length of a prism. The formula is volume = cross-section x length. Length is the distance between one cross-section to another.

Child Slavery In The Democratic Republic of the Congo

In Social Studies we are looking at our human rights and what happens when someone takes our rights away. For this assessment we had to chose a topic and a country to focus on. I decided to look at child slavery in the Democratic Republic of the Congo. Here is my slideshow.

Medical Science

Bones
Bones protect our organs and provide suture and shape that the other cells of our body attached to.

Muscles
Muscles move parts of the body by pulling on bones. Muscles are attached to the bone by tendons. Muscles work in pairs called antagonistic muscles giving us more control over our bodies and our movements. Antagonistic muscles are on both sides of a joint of example your biceps and triceps, as our biceps on the top of our arm contract the triceps relax moving the arm up slowly. Then to move your arm back down your biceps relax then your triceps contract.

Blood
There are four composts in your blood, Red blood cells, white blood cells, Platelets and Plasma. White blood cells fight infections. Plates make blood clots when you cut your skin.

Joints
There are two types of joints in our bodies, ball and socket joint and hinge joint. An example of a ball and socket joint in the shoulder, and a hinge joint is your elbow joint. The difference between the two is that the hinge joint can only move in one direction while a ball and socket joint can move in most directions.

The make up of a joint -
At the end of each end of a bone there is a tough, smooth stuff called cartilage. Cartilage stoppes the bones from wearing away. Ligament hold the two bones in place. Synovial fluid keeps it slippery and is held in by synovial membrane.

The Border Problem

This week we have started to look at algebra and what it is. To me algebra is subbing out numbers we don't know with letters or images to answer equations.

Our big problem of the week this week is the border problem. We where given a 10x10 square like the one below, we had to work out how many red squares there are without counting them all individually.

My strategy to work it out was to take a side length or row and ignore the corners for now. Times the number of squares in the side length without the corners by 4 then add the corners back onto that number to get your answer.

Mystery Genre Performance

This term we are doing a group performance. The twist on this activity is that we had to pick a random genre from a box. The genre that my group got is R'N'B also known as Rhythm and Blues. The other people in my group are Leeane and Liam. I'm playing the guitar and he's also playing guitar and sing.

What Makes A Good Mathematician?

In my opinion a good mathematician is not necessarily someone who is fast at solving equations. Nor someone who get a right answer first try, but someone who does give up when they get something wrong. Someone who seeks to understand why an answer may be wrong.

Growing up it has been ingrained into us that you have to be fast to be any good at maths, that we have to get the answer right first time. While people say we don't have to be fast or get an answer right, we are told the opposite making it harder for people to get into maths and to enjoy it.

Musical Me

My favourite artists are Avril Lavigne and Jamie McDell, because they can actually play the instruments hear and sing.
I also like Linkin Park and Nickelback
I am play the guitar.
This year in music I want to get better as a musician.
