Eye Dissection

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

Equipment 

1 : Cow's Eye

2 : Newspaper

3 : Scissors

4 : Gloves

5 : Tweezers

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 cornea where the cornea and the sclera meet.

5 : Cut around the corner 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 move 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 have now have placed the retina, lens , cornea and iris on a piece of paper.

9 : The dissection is now complete and all the 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 thrown out.

Summary :

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

Reflection/ Refraction

 

Reflection           light            reflected            normal           same          incidence When ________Light____ hits a mirror, the angle at which it hits is the ___same________  as the angle at which it is _____reflected_______. Scientists called this the Law of Reflection. In correct science terms, the Reflection Law states that the angle of _____Reflection________ is equal to the angle of _____incidence________ when measured from the ____normal_____________.  ReplyForward

2. Light + Chemical  = Flashlight

3.Kinetic + Light = Car

Aim: To make a marsgmallow shooter that transfroms energy

Equipment :

1.Platic Cup

2.Marshmallow

3.Tape

4.Balloon

5.Scissor

Method:

1.Cut a hole in the  bottom of the cup

2.Insert the balloon at the bottom 

3.Then tape it around the balloon

4.Tie the ballon after that

5.Put the marshmallow in

6. Shoot your shot

Conclusion:I didnt get to do anything because I went student reception and when I got back its time to pack up.

Energy

 Definition: Stored in an object, the ability to move something.

Diffrent kinds of energy.

- Light energy = The energy of the electromagnetic waves. Found in all Micowaves , Xrays and visble light. (flash light , candle)

- Heat enery = caused by the movement of particles. Found in all hot objects (  solar system , Heat energy)

-Sound energy =  Energy produced by vibrating objects. Examples are speech,ultrasound and music. ( solar , wind)

-Chemical potential energy = Energy stored in the bonds between particales. found in substances petrol and food. ( food , batteries)

-Electrical energy = the movement of electrically charge particles. found in wires generators and lighting.(Direct current , lighting)

-Gravitational potential energy   = Energy stored in objects due to their height above the  ground. (Airplan , Rocket)

-Kinetic energy = Energy due to the motion of an object. eg. moving cars, running, swimming

-Elastic pontentail energy = Energy stored in stretched or sqauashed objects. Examples are springs and rubber bands.

Aim: To correctly light a bunsen burner

Equipment: Bunsen burner , heatproof mat, matches

Method: 

1.Place the heatproof mat on your workbench

2.Connect the bunset burner to the gas outlet ( do not turn the gas on yet)

3.Turn the  collar so that the air hole is closed

4.Light a match and hold it 2-3cm above the nozzle of the bunsen burner

5.Turn the gas on at the tap

Today We did an experiment about how tea bag can fly when you light it.

Aim :  To obeserve convection in real life 

Method:

We went and got all of our equipment. Then we started off with cutting the tea bag.Then we tipped out the inside.And went place it on the heat mat. We lighted up and it flew everywhere.

Yes it was fun because I didnt know tea bag can fly when you lighted up

Equipment:

Cheese puffs

ngredients :
2 cups of flower
6 T baking powder
4 cups cheese - grated
2 eggs
1 cup of milk
Cayenne pepper - pinch

Method:
Sift flour and baking powder into a large bowl
Add grated cheese and mix lightly with a fork
Put eggs in to a small bowl and whisk
Add milk and whisk again
Combine both wet and dry ingredients together. But, Don't over mix
Put even sizes spoonful of the mixture onto a baking paper on 2 trays
Put oven on fan bake at 200 degrees for 10 to 12 minutes
Check if there light and golden and well risen

Today in food we made cheese puffs. I was a bit late to class so I didn't get to see how it was made. Although. I came just in time for putting the mixture in its tray and we waited until its cook. After we waited 10 minutes for it to be crispy golden brown. We took it out. I tried half of it and I didnt like it and I'm assuming its something new that I've taste.Thats why it tasted a bit gross. Even though it tastes a bit gross it still smells very flavourful and mouth watering

Evaportation Experiment

Intro : We have been learing about distillation , evaportation , and dilutions.
Evaporatain is when liquid to gas.

Aim: To evaporate cooper sulfate (sulfur oxygen) - ( Blue Liquid )

Hypothsis:

Equipment: copper sulfate solution, 250ml beaker, heat proof mat, evaprorating basin, element

Method:
1. Set up element
2. add 100ml of hot water to the beaker and place on the element.
3.Add copper sulfate to the evaporating basin on top of the beaker.
4.carefully, place the evaporating basin on top of the beaker.
5.Turn on the element to 3
6.Heat the solution until most of the solvent has been evaporated and crystals of solute are forming.
7. Turn off the element - careful not to touch as will be hot for a long time

Solute = Solid
Solvent = Liquid
solution = Mixturez

Oberservations: we saw bubble inside the water
Conclutions: My Hypothsis was right because we saw steam coming out of the water.
Discussion:
Evaluation:

Distillation

Aim: To separate a solute from a solvent in a solution using distillation.

Equipment: A solution of saltwater, conical flask, heatproof mat, a delivery tube and bung, Bunsen burner, tripod, gauze mat, retort stand, boss head and clamp, boiling tube.

Method:
 1. Set up the equipment as shown in the diagram
2. Add approximately 50ml of saltwater to your conical flask
3.Light your bunsen burner. Open the air hole and gently push the bunsen burner under the tripod
4. Heat the solutions utill most of the solvent has been evaporated.Turn off your bunsen burner.

Hypothsis: I think that the colour of he zero coke will change and there be no sugar left it in.

Rusult: After a while  it  was bubbling, It turn into a watery liquid and it went through the delivery tube

Discussion:First we had the solutions and it was coke. after that it started to bubble because we heat it. I saw steam going up thats means it's evaporating. The solutions was going through the delivery tube. At the end it turn into clear liquid which mean it was condensed.

Conclution: The protect that we did  turn out the way we wanted to turn out whice is was  great. At  the end it was colour less.

Health - Online relationships and Real Life Relationships

People think diffrent ways of online relationships and real life relationships.I think both ways are good but real life is trustworthy.I think that a person cannot truly fall in love with someone he or she has never met in person, unless you really know who they are.Online chatting is one of a way to connect decide if there are possibilities for you.But I think that real life relationships is a way to connect more.A real life relationship contain care,love,understanding,help and support whice is really good.In conclutions both way are important but online relationships may not be real.But as long they are happy about there relationships that all it matters.

Testing for simple sugars - the Benedict's Test (Test Number 2)

Aim:To test a sample of food to determine whether it contains simple sugars. Testing foods simple complex protein.

Equipment: Bunsen Burner, Test Tube Tong, Benedict's Solutions, A Sample Of Food.

Method:

Milk is not complex.

Protein:
Potato: neg
Apple: neg
Milk: Positive
Egg: Positive
Bread; Neg
Sugar: Neg

Complex Sugar
Simple Sugar

So my conclusion is. I am so surprised that potato didn't have protein. Because obviously milk and egg have protein in it.
