Corrections for WS 4 & 5

Hi boys,

Sorry that I did not manage to give out these instructions in time during lesson time.

You would have received back your WS 4 & 5 today.
If you have not, pls see me on Tue morning before assembly to get them.

Those who have outstanding corrections, do take note:

1. WS 4 & 5 biological drawings corrections
-Remember to apply the standards learnt; pls refer to the checklist given last week; re-draw the cells
- Certain cell parts not labelled; add in missing labels in green ink

2. WS 4 - Purpose of using food colouring & iodine solution

Keywords in your ans:
- cells are colourless
- staining enables cell & cell parts to be viewed
- more easily

Ulvis, Yi Heng, Wee Kean, Lidrean, Anselm, David, Asher, John, Lei Yu, Darren, Joel:
I will like to mark your corrections on Tue.

Rgds,
Mrs Ng
