Cheers for now,
Karen

Re: bell jars

Thanks one and all for your tips.
I ended up listening (via a sound level meter) for an increase in sound once the vacuum was switched off - worked like a charm - even the Year 10's were impressed - and that takes a lot!
Have a great easter,

Good afternoon all,
We are having difficulty evacuating air from our bell jar (housing a ticking clock) to the extent that the clock can no longer be heard.
Any hints??

Re: Disposable gloves

Earth and Environmental Science

Hello all labbies,
I've had a request from our EES teacher to find WestOne 1A, 1B, 2A, 2B resources. Apparently government schools were issued with these resources for free.
Hope someone can help,
have a good weekend,

Good morning all,
Yes, here in WA we have a School Animal Ethics Committee (SAEC) for any work involving animals. Paper work is lengthy and a pain but apparently necessary!
