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

Energy Transformation Experiment

 1.Chemical + Electrical = A Phone

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:

Match 

Lighter
