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 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

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
