Re: setting / mounting agent for very small bones
Not really. We just did the Owl Pellet prac here, and kids glued them onto black card using PVA glue. We only kept one or two of the good ones.

Re: flame test in spray bottles??
I use the coke bottle rig that Ocker posted years ago, and it's still the best way to see flame tests.

Re: Talc
In my year of nothing-to-do - aka Chemotherapy year - lots and lots came across my email. Basically, talcum powders are supposed to be asbestos free, as from 1973 or some such date. I guess there could be some concern with cheapo overseas produced ones. Talc the rock occurs naturally with asbestos, ...

Re: Bucket chemistry
I have a teacher who just blindly copies out whatever is in the book. So I have been asked in the past for 30 x 250mL beakers, with 5cm strips of zinc to go in each, followed by 100 - 150mL of HCl. Nope! Not doing it. We went test tubes and tiny strips of zinc. So, yeah, there are quite a few "...

Well we have geckos, but since they come and go as they please, I guess they don't count.

Unexpected results - gotta love Biology
Our little tinies - aka Yr7's - did an experiment over the weekend. Pretty standard stuff: Elodia in flasks - one in the dark, one in the sun with no extra CO2, one in the sun with CO2 blown into the water, and test tubes to collect the (hopefully) O2 generated. All good so far. Today a little cheru...

Re: weirdest things
You know those Lab Tech instructions that begin with ....Simply blah blah blah. Well I had to "simply" get some marsupial hair, to make a cross-section slide. This shows that marsupial hair has a figure 8 kind of a cross section, whereas all mammals - humans, dogs, cats, cows etc - have an...

Re: Which plant is best to use?
We use hibiscus bushes in the garden. That way later we can then compare the variegated leaves v the all green leaves as well.

Gas collection tubes or eudiometers
Hey guys, I have a question about graduated glass gas collection tubes - not gas jars but those things like long skinny test tubes with graduations on the side. They all seem to have a "header" space at the top. If we're using them for a stoichiometry experiment, then how do we take into a...

Re: Good quality burettes
Should have a tiny O-ring at the top of the tip, where it goes inside the orange holder bizzo.
If not, give them a call. I bought a few extra tips last time I bought burettes, as part of the Irish solution, You know - to be sure, to be sure!

Re: lead iodide and lead Nitrate.
Same reply. No. Pick another reaction. Or do it in micro test tubes and measure the height of the precipitate and make "relative" statements, rather than quantitative ones. Well..they are quantitative this way, just differently quantitative. Try this one instead: http://m.learning.hccs.edu...

Re: lead iodide and lead Nitrate.
Bucket Chemistry! Gotta love it. There's another one somewhere where they ask us to give a kid 3 beakers with 100mLs of HCl in each, and then hand out 5cm strips off Zn, Mg and Cu! Yay! Talk about pop test! Blow the windows out on a good day, I'd think. 8O In short - I said NO. :mad: I handed out mi...
