Piglets were amazing. Organs much bigger, not smelly like rats. The students really benefited from and enjoyed that dissection!

Are there any other good science equipment suppliers out there other than:
Labtek
Haines
Livingstone
OfficeMax
Westlab
Serrata
Southern Biological
Biotek

Finding it harder and harder to get things at decent prices. Spend my days going through catalogue after catalogue.....

Thanks Rosalie.

Not many come with the % on the bottle, so we've had to find it on the MSDS or manufacturer's website etc.

Hi everyone, Each year we find it harder and harder to get different types of vinegar with different % of acetic acid in them, which also have the % listed on the bottle. All vinegar seems to be around the 4% - 5% mark. This year, we've been asked to supply white, white balsamic and apple cider vine...

Where do you all buy your DI water from?

We have a Millipore deioniser which we need a new cartridge for. We ordered it 8 weeks ago and still not coming despite checking, ringing etc.

Having to resort to buying water.

Very disappointing that Chemwatch seems to have moved away from providing a good program that can be used by schools as well as industry. Common solutions (HCl 0.25M or 0.5M) are no longer found on a search. :banghead2: When "renaming" them they come up with 3 lines of chemical names which...

Thanks everyone, We make our wine in fermenting jars. Don't know why the teachers don't want to use the hydrometers. Possibly because they missed a step and didn't take a SG reading before???...... #-o We got an alcometer from a brew shop and they've used that. They wanted a vinometer which are chea...

Hi everyone,

Can anyone advise the best and easiest way of determining the alcohol content of wine?
Teachers don't want to titrate or use a hydrometer..........

Hi Nickyw,

We are a Catholic school so don't have CARA

Hi everyone, Can someone let me know which Aus Standard or other guideline states that Risk Assessments should be done for each prac? We are struggling to get teachers to do RAs for each prac each time that they are done. At the moment we have a RA for eg Year 9 Term 2 "Kitchen Chemistry" ...

Thanks!

We have some evaporating dishes which have been used for an Evaporating Coca Cola Prac. The dishes have had the Coke burned onto them terrible and nothing will get it off (scrubbing, bleach, HCl).

Any help?

Thanks Smiley!

The task sheet and ingredients list looks great!

We use lots of stuff - apple juice, apples, bananas, orange juice, dextrose/brown sugar/sucrose, tea bags, sultanas, citric acide, tartaric acid, wine yeast, yeast nutrient, pectinol, gelatine, and the list goes on!

Year 11 Chemistry classes here have been making wine for the last three years, but we still have not perfected the process and get mixed results. Can anyone send their procedures and ingredients for making wine so we can go through them to prepare for next year? We can't use stone fruits due to avai...
