Hi . Great site and love all the updates especially the quizzes but the Physics CE practise question paper actually shows all the answers as well as the answer paper . Biology and chemistry are fine . Thank you .

Thanks for your comments. All the pages are correct. I expect an old page is stuck in the cache and it should work as expected if loaded again.
Good luck with the C.E. exams!

Heating sulphur in air:
If heated very gently sulphur will MELT. Melting is a physical change.
When heated more strongly sulphur will start to BURN with a pale blue flame and producing choking fumes of sulphur dioxide gas. Burning is a chemical change.

Word equation for the reaction that takes place when sulphur burns (combines with oxygen):

Sulphur + oxygen —>; sulphur dioxide

how do you make a cheek cell slide?

Michael Curtis

These are the instructions for preparing and viewing a microscope slide of some cheek cells:

1 Take a clean microscope slide
2 Rub a clean cotton bud around the inside of your mouth and then smear it across the middle of the slide.
3 Add one drop of water followed by a drop of methylene blue stain
(The stain is a special dye that helps the nucleus and membrane show up better)
4 Place a cover slip on the drop (at an angle so that there are no air bubbles)
5 Squash it down gently using a piece of blotting pape
6 Place the prepared slide on the microscope stage.
7 Adjust the light source so that it shines through the slide.
8 Focus by turning the focus knob so the lens AWAY from the slide
