THE EYE

HOW DOES LIGHT TRAVEL FROM EYE TO BRAIN - The light travels through your pupil to the  lens, the lens focuses the light on to your retina , light sensitive cells at the back of your eye . The retina changes the light into a nerve signal. The nerve signal travels along the optic nerve to your brain. the iris is the only eye part that light cannot go through .

WHY DOES COWS HAVE NIGHT VISION - Dogs and cows and other animals have a tapetum. A tapetum is a reflective tissue that cause light to reflect from animals eyes in the dark. It is located within the choroid layer of the eye



THE DIFFERENCE BETWEEN THE HUMAN AND COWS EYE -
 - The size of a cow is a little over 1/2 inch with a diameter of 1.2 inches whereas the human eye is 1          inch
-  The shape of the cows pupil is oval and round in a human eye and the iris of a cow is almost always      brown whereas the human's iris come in different colour. The human eye also have a higher number      of attached muscles than a cows eyeball
- cows can see at level 20/80 in the daytime

MONARCH SEEL PARAGRAPH - SOCIAL STUDIES

Currently I am a Swazi monarch and I am an absolute monarch. Since I am an absolute monarch I am not limited or restrained by laws or constitution aka I have complete control over all aspects of the society including ; political power, economics and all forms of authority. Because I am a monarch I spend my my free time chatting to my family and watching movies in the house of Dlamini. I plan to rule for life and have my eldest daughter flourish.

Convection- science

AIM - OBSERVE CONVECTION IN A LIQUID

METHOD - 1. SET UP A BUNSEN BURNER ON A HEATPROOF MAT. PUT THE GAUZE                                 MAT ON A TRIPOD BUT LEAVE IT JUST TO ONE SIDE OF THE BUNSEN                               BURNER
                     2. FILL A 200 mL BEAKER WITH 150 mL COLD WATER
                     3. PLACE THE BEAKER ON TOP OF THE TRIPOD AND GAUZE AND ALLOW                           IT TO SETTLE FOR A FEW MINUTES
                     4. CAREFULLY INSERT A DRINKING STRAW DOWN ONE SIDE OF THE                                   BEAKER, BUT BE CAREFUL AS YOU DONT WANT TO DISTURB THE                                   WATER TOO MUCH
                     5. USING TWEEZERS , DROP A CRYSTAL OF POTASSIUM PERMANGANATE                           DOWN THE INSIDE OF THE STRAW. WAIT FOR THE CRYSTAL TO                                         SETTLE ON THE  BOTTOM OF THE BEAKER
                     6. VERY GENTLY, SO TO NOT DISTURB THE WATER,REMOVE THE STRAW
                     7. LIGHT THE BUNSEN BURNER AND SLIDE IT UNDER THE TRIPOD SO                                 THAT YOU ARE ONLY HATING THE OUTSIDE OF THE BEAKER WHERE                             THE CRYSTAL IS. OBSERVE

DISCUSSION - The purple water rised

RESULT -

PARTICLE THEORY OF MATTER, CONDUCTION - SCIENCE

AIM - TO OBSERVE CONDUCTION ALONG A METAL ROD

METHOD - 1. SET UP AND LIGHT A BUNSEN BURNER
                     2. SMEAR A SMALL AMOUNT OF PETROLEUM JELLY ON THE HEAD OF                                 EACH DRAWING PIN
                     3. ATTACH THE DRAWING PINS AT EVEN INTERVALS ALONG THE                                          LENGTH OF THE METAL ROD
                     4. CLAMP ONE END OF THE METAL ROD TO A RETORT STAND
                     5. POSITION THE RETORT STAND SO THE UNCLAMPED END OF THE                                      METAL ROD IS IN THE BUNSEN FLAME
                     6. RECORD THE TIME IT TAKES FOR EACH PIN TO DROP IN THE TABLE                                 BELOW


DISCUSSION - When particles at one end of a metal rod are heated, they begin to vibrate more. Vibrating particles collide within sticking particles making them vibrate faster and transferring they energy along the bar.

Chernobyl Disaster - Social studies

1 Week ago our class was told to research some of disasters that happened through the years. I chose to search about the Chernobyl disaster that happened in 1986 ( approximately 33 years ago )

What I already Knew :

 - A nuclear disaster
- City is officially abandoned 

-  Able to visit but its very strict 

-  2 people died on the initial explosion

What I learned :

- Over 100 people got affected by the radiation 

- Reactor 4 exploded

- There is an exclusion zone 

- It was spread to other city close to it

- Happened 1986

- Home to wild animals 

Art

This term we have been working on culture clash between manga and pasifika patterns. We started off with planning of course then we slowly worked up to our final painting throughout the term.

We had many different concepts and started developing them to get to our final idea. The whole point of concepts and developments is because they are a plan to get to where we wanna be.

I think I have used Colour theory right now, I will admit it wasn't easy to get the plan but I did get it in the end.

In my process of painting I put some of my feelings and thoughts in with my colours. I think the way I painted brought out a lot of feelings so I put it into my work

Raising agents

AIM - what is the best raising agent

METHOD -  1. Measure 1/2 tsp raising agent into a test tube

                     2. Half fill the balloon with water

                     3. Put the balloon over the test tube

                     4. Tip in the water

                     5. Record what happens to the balloon

                     6. Warm gently

                     7. Record what happens to the balloon

                     8. Leave to one side, Record what happens after 5 - 10 mins

  

OBSERVATION - The best raising agent is the baking powder because it inflated the balloon faster than the active yeast

TYPE OF RAISING AGENT	INITIAL REACTION	AFTER WARMING	AFTER 5 MINS	AFTER 20 MINS
BAKING POWDER	Fizzed up and inflated the balloon	nothing
BAKING SODA	Dissolved in the water and kinda inflated
YEAST & SUGAR	It did not dissolve fully like it was supposed to	Foamed up	Balloon got bigger
