Hi Di

I store some litmus paper in a jar with a few drops of ammonia. Put something between the paper and the ammonia so only the fumes get to the paper. Works ok.

Thank you Rosalie and Liz. I'll get straight onto it.

Renewing my call for help on the course application form. I would appreciate a copy if someone could fax it to me please, or just put up the contact details for the course so I can contact the person concerned. Thanks.

Julie

Help!! 8O My Principal has approved my attending the course and promptly lost the form, which I included with my application for funding. #-o Silly me - I knew I should have kept a copy! Could somebody out there please fax me the form on 66572281 - att. Julie. I would really appreciate a quick respo...

Is this "Update" because the DET has issued an update of their materia/guidelines, or for those people who havent done the training( ie the training thats been the same for a nomber of years?) The form I received says that it is for the ones who haven't done the training. It doesn't say a...

Hot water usually loosens them up without too much effort.

Hi to the other country kids

I've applied for T&D funding for the course costs and air fares. Hopefully the powers that be will come to the party and any other expenses I will claim on my tax. I have a friend I can stay with in Sydney. Might make a weekend of it.

Hi Rosalie

I just got mine in the mail today. I'd love to go but will have to jump through all the hoops again to see if I can go.
I'll PM you if it's going ahead. Thanks.

Does anyone know if there will be any similar training conducted in regional areas? I would love to do this course, in fact I think it may be the one I booked and paid for last year but they cancelled it. :? It would be a lot easier for some of us country kids if we could have more local access to t...

I found these recipes at easyfunschool.com. Please note: take note of the ingredients listed and be aware of possible food sensitivities and allergies of the children involved. Edible Rock Recipes: Igneous Rocks 1 can evaporated milk (6 oz.) 1 1/2 cups sugar 1/4 teaspoon salt 1/2 cup chopped nuts 1 ...

Absolutely! I wash nearly EVERYTHING in mine. Some days I'd almost climb in there myself if I could. How do you survive without one? And ours is a very small school with only 2 labs!

Hi Lindy

Go to http//www.nasaexplores.com/show_k4_teacher_sh ... 0803103618 for some different recipes for various types of rocks. Looks like you could make it reasonably cheap by varying some of the ingredients. Very American but just use our alternatives.
Yum. Chocolate!

I love brussels sprouts!!
I guess that means I'm a non-taster.
Wow! The things you learn on this site!

The Surfing Scientist on the ABC website is worth a try. All sorts of odd things and conundrums that will confound and baffle your students. Some are ordinary and predictable :coffee: some are good fun and will have them mystified. 8O This guy did a presentation at the last St Marys conference. His ...

Some days are diamonds.
Or so they say.

Hi Tammy Way before my time here I know that students have prepared things like rat and rabbit skeletons by boiling off the flesh. Sounds totally gross but if there's not much flesh left it might be ok. A quick google search found this little snippet which may be of assistance: PROMISING NEW METHOD ...

Thank you for your contributions. We have settled for copper sulphate and bought some from our local produce store for $4.50 per kg. Probably not of the standard required for senior chemistry experiments, but fine for making crystals and the usual 'bucket chemistry' we conduct in the junior school. ...

Thanks Kristin Checked out the CSIRO website and had a bit of a play around with various substances. We finally settled on the good old copper sulfate crystals. You can't really beat them for colour, speed of formation and shape. Even though we see them all the time the kids are still impressed by t...

Yowch!!

I would suggest either a spray of WD40, or perhaps a soak in paraffin or some other oil. Leave it over the weekend and on Monday give it a GENTLE tap.
Hopefully that will do the trick.

Good luck
Julie
