Eye Dissection

 Aim: To dissect a cow's eye and look at the different parts of the eye.

Equiptment: 

1.  A Cow's eye

2.  Tray

3.  Tweezers

4.  Scissors

5.  Newspaper

6.  Gloves

Method:

1. Set up a tray with newspaper on the desk, the tray on top and the scissors and tweezers in the tray.

2. Put on a rubber glove.

3. Start to remove the excess fat and meat from around the eyeball before dissecting it.

4. Puncture a hole in the corner where the cornea and the sclera meet.

5. Cut around the cornea so that the vitreous fluid leaks out of the eye onto the tray.

6. Once the cornea has been totally removed you will be able to remove the lens from the iris.

7. Cut the eye in half so that the inside is totally exposed. Once this has been done you will be able to access the retina at the back of the eye.

8. You should now have placed the retina, lens, cornea and iris on a place of paper.

9. The dissection is now completed and all parts of the eye need to be wrapped up and trashed. The trays and utensils that were needed must be rinsed and the rubber gloves throw out.

Summary:

The cow's eye has exactly the same parts as the human eye except for its ability to see better in the dark.

Labour Day

Labour day is for your parents and children but children do school not same as with there parents. Parents who work a lot and they have time to relax there self for one day and hang out with there family. Also, labour day is to celebrate the achievements of workers.

3.  Will it be good for your wellbeing? Yes, cause you can exercise your body in the morning and spend time with your family and friends.

Reflection and Refraction

Definition

Reflection
The bouncing back of a wave when it hits a surface through which it cannot pass.

Refraction
The bending of a wave as it passes at an angle from one medium to another

Incident ray
Incoming ray

Reflected Ray
the light ray that bounces off a surface

Refracted Ray
The Ray that has bent as it enters a new medium

Normal line
An imaginary line is drawn perpendicular to the surface of a mirror or any surface

Angle
The amount of bending that a light ray experiences 

Complete the sentences using the following keywords:

Reflection   light   reflected    normal   same    incidence

When Lights hits a mirror, the angle at which it hits is the Incidence as the angle at which it is Reflected. Scientists called this the Law of Reflection. Incorrect science terms, the Reflection Law states that the angle of Normal is equal to the angle of Same when measured from the Reflection.

Research Task:

1. What is a periscope? Is an optical instrument that uses a system of prisms, Lenses or mirrors to reflect images through a tube. 
2. How does it work? Light from a distant object strikes the top mirror and is then reflected at an angle of 90 degrees down the periscope tube.
3. Draw and label a periscope?
   
   

Market Day

Yesterday is our market day, I and my friend was selling ice cream but first, we bring all our stuff outside in the classroom because we saw lots of people bring their stuff outside and 1 group that making sausage with bread, they are starting cooking it. But we did bring our ice cream we put it on the refrigerator because it will melt if we put it on the table with a sunny day. After we put our stuff on the table we starting putting our banners on the table where we sell our product. Our company name Cream Joy, meaning our company selling ice cream. I was in the group with Alex, Jullien and Jesse. When It almost period 3 lots of people coming and buying food and others, I and Jullien just looking around and trying to find some food that we want to eat.  Suddenly Mr Scot Speaking and telling us what to do like where to change ur money to a paper so people can buy something on the Market day. He Also tell us the DJ who is going to put a music and just staiyng on the music speaking. When the market day started a lots of people coming on our Ice cream sell because it so chip $1 each, at the end of the market day our profit is $34 and maybe next time we bought 4 pack of ice cream than 2 because alots of people want to buy an ice cream and we bought doritos for nothing we don't even use it on the ice cream we only use cones and sprinkles.

Political Party

 What are we doing?

So guy our teacher said that we are going to do the political party si there are 4 classes name and in every class, there will choose 1 in that class and 1 in the other class so they don't work with there classmate and work with other people that you don't normally work.  So my group is Aryan, Cody, Chara and Saiha we are thinking about the name of our political name, suddenly Aryan said that the name of our political is Mint and all of us like it and we tell to the teacher that our name of our political name. Then Aryan make a very cool logo and we all like it and would love to be our logo, then after we did the logo name now we are thinking about the slogan and My group member said that the slogan will be 'Let's get Mint' and then we are choosing  5 policies that we will focus on. We are choosing who is our leader in this group and all member except Aryan, the member said ''Aryan will be our leader'.

5 Policies You Will Focus On - Look back to the list on the slides  Plant more trees around New Zealand More bins around New Zealand More access to counselling and mental health support.  Try to get the cafe to use less plastic Free mints in every classroom

Here are our Logo and Slogans

Energy Transformation Experiment

8 different kind of energy

1. Sound Energy
2. Light Energy
3. Heat Energy 
4. Chemical Energy
5. Electric Energy 
6. Kinetic Energy
7. Potential Energy
8. Elastic Potential Energy

1. Chemical  + Electrical = Phone
2. Light + Chemical = Flashlight,Car
3. Kinetic + Light =  Conect

Aim: To make a marshmallow shooter that transforms energy.


Equipment:

1.  Marshmallow
2.  Cup
3.  Scissors
4. Duck Tape
5. Balloon

Method:

1. Take the scissors
2. Cut the bottom off of the cup
3. Take the balloon and cut the bottom off the very tip after you cut it off you will take it and stretch it over, the top of the cup where you cut hole once it's on you will tie and knot in the end where you would normally blow air into balloon tie it off.
4. In order to secure the balloon over the top of the cup take a piece of duct tape and wrap it around securely tapping the balloon to the cup, this will allow you to be able to pull the balloon as far back as you can without snapping off, You will now take a handful of marshmallow this will be your ammo that you will able to shoot far distance with to prepare your new marshmallow and place it in the  very centre of the bottom of your cup 
5. You will now take hold of the end and pull it back as far as you would like in order to gain
6. Have Fun!

Here is The Video

Conclusion:


 This Experiment turns from Elastic  Energy ➡ Kinetic energy. 

Energy Transformation

                       The Law Of Conversation Of Energy

Energy can't be created nor destroyed, but only change from one form into another form.

Example of Energy transformation 

• Flashlight -Chemical-light
• Car-Chemical-Kinetic, Light sound
• Phone-Chemical-Electricity-Light, Sound, Heat, and chemical energy
• Laptop-Electricity-Light, Sound, Heat and chemical energy
• Radio-Electricity-Sound

Aim: To look at the energy transformation


Equiptment:

Paper

Scissors

Summary:

The paper will get burn and more fire going on

What kind of energy was transformed?

To heat energy

What was it transformed too?

The heat energy to kinetic
