Australia's Science Forum

I attended a CSIS course last year (along with a few others from here) run by the Royal Australian Chemical Institue NSW Chemical Education Group. Margaret Lindsay was the contact person for it but I don't have her contact details with me. You could probably look them up and contact them to ask if t...

Perhaps it isn't so much of a priority at the time of the accident, but when they have been stabilised and transported to hospital someone there can make the calls.

This sounds like so much fun, (the diet coke and mentos) but I am not quite sure how it relates to rockets, since nothing is actually 'launched'... Is it used as an example of how fuel is blasted out? A junior school teacher has asked if I have any exciting science things to do with space. We did th...

I got some plastic bottles free from the hospital. Have a read under the topic "Duran/Schott Bottles" for more info and to see photos. They aren't good for everything, but I keep most solutions in them.

Hi again... The kids are doing a prac where they pour different materials through a funnel and look at how it falls, measuring the height and spread. I've got the coarse sand, fine sand and candles (they just get melted - not through the funnel!) and the other thing is blue metal. Where would I get ...

I've finally got around to washing some sand (because I was asked for it and of course we didn't have any!) and it turned yellow... I washed it again with water and the yellow came out into the water. The sand has dried again and is still yellow, although not as bad as before. I don't think it's and...

Sorry guys... I guess it was me who started it all off late last year!! I was sure I was responding to a new post!! But now I see I was more than a year later than everyone else! I'm curious now... I'll have to look through and see if there was a similar thread going on around that time... Thanks, J...

How do you find all these fantastic sites???? I just had a quick look at it. I'll be showing this one to the teachers!

Yay! I got it to work! At least I think I did... Had to shrink them a fair way... sorry they are blurry - they weren't the best photos to start with! Now I need to get back to the lab... I don't usually spend this much time on the computers in one hit!

I have taken the photos of the bottles for you but our computer security won't let me put them on. I'll have to ask for help... They are plastic bottles, HDPE, so most things can be stored in them. There's a table on page 28 in "The Laboratory" which indicates what can and can't be stored....

We use bottles which we got free from the hospital. I think they were from the pathology department. They hold 2L and are only about 6cm wide 23cm long and not quite 21cm tall (where the lid is). I'll try to take a digital photo and post it up tomorrow. The fit perfectly on our shelves and don't was...

Is there a way to clean out incubators? We had some plates go in which weren't very well sealed (two pieces of sticky tape to make a cross on top of the petri dish) and now our incubator is a rather smelly... which I'm thinking can't be good! I just want to know if there's something I can spray in i...

You would think if they banned a substance they would change the curriculum and create a new prac! I just tried to purchase Ammonium nitrate, having forgotten it is no longer available. This was discussed last year and potassium nitrate was suggested for the endothermic prac. I don't know if it will...

I don't know if it is quite what you are after, but we do one with dialysis tubing. Cut off about 10cm. Tie a knot in one end. Put some glucose solution (we used 5%) in and tie it off with string. Place this in a beaker with water and some benedicts solution with the beaker being in a hot water bath...

Do you buy deionised water or distilled water (and what's the difference?)? I haven't seen distilled water in supermarkets, only deionised. Big W has some in 4L bottles but they run out pretty quickly and storage/disposal of the bottles is an issue. I get distilled water in 20L containers from the l...

sometimes it depends what you put in the search thing. If you type in 'reliable ph meter' you will get to the thread I was talking about. Happy searching

That's hillarious! Of the thousands of languages here on Earth, what makes the 'scientist' think the Aliens will speak English?

There was some discussion on this towards the end of last year. If you do a search for ph meters and scroll down about 5 posts you will find it. Click on the topic line and it will take you to the discussion.

I'll be passing that link around to the teachers I think - Thanks, Jen, for finding it! I remember seeing it when I was at school or uni. It's amazing stuff.

Sorry - forgot I can't put websites on here. I don't have the Haines catalogue (do they have them? we just get the pieces of paper every now and then...) but do a google search for Haines and you should find them.
