Yep!!! here at the College we have just finished with the bacteria.agar plates
and it is ok to wrap unopened plates tightly in newspaper and tape up.Then wrap in plastic.However I always write BACTERIA WASTE very clearly for the cleaners to know what they are handling.

Hi there Helen The task that you have been asked to do is near impossible to put down on paper for someone else to follow. If the other person is not experienced, responsibility lays with your manager to help this person, not yours!!!!! I'm astounded that you were even asked to do this. If the other...

Once again you guys have come up with the goods!!!!!!!

I'm needing help again!!! I already have about 8 ester combinations.But what I'm looking for is a combination using Propanoic Acid. One of our Chemistry teachers who used this has now left and no one else knows what the mix is or what fragrance it produces.I have a feeling it might have been roses!!...

Many thanks everyone, great stuff!!! Will pass info. to teachers.
Pilar, I was unable to connect to the website you gave me.Bit of a shame really.

Ask your Head Teacher of Science if he/she can allocate you $400.00 for the school year.It needs to be done when each faculty is asked to submit their budget for the year.This is usually done during last term of the year for the following year.When I require money to buy science stuff I write a subm...

Hi Terry
Just read your other message!! The Dept. of Education and Training pays a fee every year for the schools to be able to access this site.You should have easy access to it on your DET site by typing in: detwww.det.edu.au/assessmentmanagement/chemicals/.
Good luck

In 2005 I finished a 2 year Science and Administration course through the Department of Education and Training at my College here.It was done through TAFE and you will be accredited and the Certificate is recognised throughout Australia.(Will look great on your CV!!!) This certificate 111 in Educati...

Thanks everyone for your input and yes, I did calibrate the meters I have.Maybe the pocket size meters are just not up to it.

Hi all
Can anyone out there in lab. land recommend a reliable PH meter!! I have 2 hand- held meters but they are useless. I need fairly accurate readings for Yr. 12 in particular.
Thanks
Mother

Hi there PolyEster
We have always done E & E Science here at the College and have text books for Yrs. 11 & 12.If you let me know your school fax number I can fax you whatever pracs. your teachers might be interested in.Are they going to follow a set curriculum?
Take care
Mother

Thanks everyone for you input.I'm surprised the teacher didn't have ideas of his own!! Oh well, some mothers do have 'em

I am seeking assistance from anyone who has a simple and easy experiment for the Doppler effect using rotating sound sources !!
Wow,it has been so busy I have barely had time to look at this great site. I know someone out there in Lab. land will help me out with some great ideas!!
Thanks

Hello all
I have just made a starch solution for the Osmosis experiment using dialysis tubing etc. I made 500mls using 10g of potato starch. This is good enough for any experiments that requires starch solution.
Hope this helps

Hi all Just to let you all know that I have followed up on the ruling for MSD sheets from the OH&S regional meeting.It has been recommended by the department that mini MSD sheets be available in hard copy with the central register(admin. office usually) and at location sites where applicable ie....
