Oh yes that does sound like fun! JOKING!

We're in Lake Macquarie, Labbie

We have a lot of preserved specimens that have seen much better days!
They are all in 50/50 metho and water.
My H.T. wants me to get rid of them.......what should I do with all the dead bodies?????
There's rats, snakes, frogs and all sorts of "bugs".

Thanks in anticipation.......

I have one of these, in the dark depths of the storeroom!
No idea what it is though!

We started using Risk Assess for the first time last year, I too am a novice, but I find it really easy to use. As Merilyn said so long as the teachers fill it out correctly!!

Superbug,
I printed off a list from CSIS appendix H.

Hi Tuesday,

I have tried to access the list on ASSIST but for some reason am unable to! Will have to get our tech guy to have a look.....when I can pin him down!!

we use it for slime, crystals, I've gone through a fair bit of it this year

I found 3 blocks here they are about 3cm square, which are perfect! The teacher who wants them wont be submersing them she only wants to weigh them etc to show the different densities. I've found the 1cm ones online, and we do have some 1cm metal cubes here but they are so small, not very user frien...

We have, in each lab, a block of wood attached to the wall, about 3 feet or so high with nails banged into it and the bunsens hang on the nails, works well.

Thanks for your replies people!

Cheers )

Hi all,

I'm wondering if anyone has recently, or ever for that matter, purchased a density kit?
The teacher who wants one is after shapes of the same size but different densities?

Cheers
