great idea Bindibadgi
very clever indeed.

Does the polystyrene cope with boiling water?

I'm looking for ideas and/or worksheet resources for making a booklet that can be used by Stage 4 - Year 8 students to observe the geological environment at here at school (e.g. rocks, types of rock , weathering etc.). Also, video clips (new clip?, U-Tube?) of erosion/weathering events taking place,...

Yes, I could. I have been thinking thought re the Ca, Mg & Na OH. The idea is to have less water at the beginning , and more later on. But with both those pracs I will have to modify to add the water all at once..or else risk hazardous situtaion... then log temp rise as the reaction progresses. ...

thank you both for these.

Anyone help me out please? We have a yr 8 prac that uses plaster of paris, add so many drops of water, and time the temperature change every minute. Then we want the students to take the raw data and graph it. BUT the problem is that we havent been getting satisfactory temperature changes in the pra...

Yes Rosalie

Do you use ChemgoldII at your school?

& have you tried to access the existing ChemgoldII lately?

Any success?

If not, then youve been moved over and no-ones told you yet?

PS thanks for starting this thread IAN..

I think it will be a valuable resource as we all learn,

and can share and help each other

Ha ha! welcome to the exciting world of new learning experiences!

I think that we are all sharing the thrill of the new learning curve!

Step by step...little by little... here we go

WHEEEEEEEE!!!!!!!!

Nickyw and Bindibadgi

THANK YOU SO MUCH! for these resources.
They were SO timely, using them in classroom now!

We have lots of little greeblies in our pond waters...anyone have an Identification chart ?

Thank You Bindibadgi

Very grateful

Thanks all

Rowyrow

I will make some of that up. Thanks

oops!

Bindibadgi

I forgot to add. I would love a copy of the pracs that you use.
Thinking of an animal (insect respiration), a plant one, and a combination of the two, in sealed tubes. If you have any other good ones I can have those too!

Thanks

Thanks Binibadgi
This is exactly what I need!

I need to differentiate some live greeblies from the surrounding plant debris, for viewing live under the microscope.
Whats the best stain anyone's used?

Hydrogen Carbonate indicator solution.. the one used to indicate the presence or absence of CO2

Anyone know how to make it/or have a prac using the coloured indicator?

Thanks

A question about the 9 days soaking in saturated salt soln.

Do I replace or refresh the salt solutiona t any stage during the 9 days?

Well done Xe !

Those certainly are "magic words"

They shouldnt be doing that prac without having a Risk Assessment . The risk assessment will cite opening agarplates as a biohazard risk. It will aslo say, do not open plates, unless under fume hood, gloves etc , wash areas with metho etc, and other controls in place. If theres this conflict of proc...

same for me, I cant open them either .
