Re: Not Happy
Ann, I'd accidentally buy a $20 one from Big W with petty cash, until they get you a proper one. :thumbup: I accidentally bought a microwave once. Oh and a "thermal heat transfer unit" that as well as performing Latent Heat experiments, also, completely coincidentally, makes coffee. :w00t:

Re: Non contact infra red Thermometers
We also use ours for Biology/HPE. Get the little treasures to run around, and then take their temperatures in their motuhs with clinical thermometers, and off their foreheads with the non-contact thermometer and show them how sweating cools you down, since their sweaty little foreheads will be coole...

Re: MSDS'S AND GHS
What's worse than no-one caring?

Re: human pathogens in agar plates
You are not wrong. NO human pathogens. No no no.
What's the purpose of the prac anyway? Looking at "germs" or something more specific?

We used Cheezels. Scary to see how much oil actually seeped down the side of the alfoil covered corks!

Re: spreading infection
Hey Guys, In light of recent new events, we have added in a variation to Nicky's "Who Spread the Disease" prac, which works really well! :clap3: Gotta love it when an experiment variation does work first time! We do two trials. In trial #1 we use 0.1M NaOH, and phenolphthalein, do 3 liquid...

Re: Manganese dioxide
It's been addressed somewhere else here, but basically it goes like this: MnO2 on its own is considered a "naughty" these days. However, it is possible to make cute little MnO2 pellets by mixing 1 teaspoon of MnO2 and 1 teaspoon of Plaster of Paris in a little 100ml takeaway container, wit...

Re: Photosynthesis and Respiration
What that means is that if perchance you have a mystery source of Elodia, just tip it all onto paper towel at the end of the experiment and let it dry out and die. Then bin it - rather than tipping leaves etc down the sink. Its the same up here when cane toads mysteriously pass away and we do autops...

Re: use of Phlorogucinol and Lycopodium
Lycopodium can be used like a type of flash powder. Chuck a teaspoonful into a campfire and it flashes and crackles like a magic trick. We used to aerate a little pile of it inside a tin with a lit candle (by using a length of aquarium hose), and it would flash and blow the lid off the can. You can ...

Re: Decomposition
Can't see that there's much difference between a side-arm test tube, and one with bent glass in the top, except, as Adrianna says, lack of durability in the bent glass bizzos.
