Hi everyone

I have noticed that on one of my prepared slides the cover slip is smashed.
Does anyone know how to fix this problem or am I better off just tossing this one.

Cheers Nicky

Hi Barbara

I have read about using adhesive tape to clean off the iron filings. I havent tried this myself so I'm not sure if it will work but its worth a try.

Hi Anastasia I have 48 hours notice as I have only been doing this job for 6 months. Most of the time the teachers give me plenty of time to make up pracs.

Hi Kim

We store our cords on a piece of thin wooden board and clip the cords on top and bottom then hang with a bit of wire on a hook on the walll and back of the door.

Works well, no tangles and easy to count.

Hi Vicki

Perhaps you could try beetroot juice, red wine, cold tea, liquid obtained by boiling geraniums, purple violets or blue hydrangeas. These alternatives were in the Jacaranda Science Book2 page 61.

Hope this helps

Hi Julie

The display is probably more targeted at junior. i was thinking of an equipment display, or rocks or maybe a mobile just something to brighten up the room. Security is a big issue though so not a hands on display. I'm only new to this job so any ideas will be appreciated.

Thanks Nicky

Hi all

I have been asked to set up a science display in one of the labs. It can be anything to do with science. Does anyone have any great ideas that maybe you have set up at your school.
