Hey guys, Does anyone have a recipe to make up 1L of 1M Fe(SCN)2+ ?? I did it last year & now can't find my recipe! I know I didn't use a stock chemical for it & I remember it involving making up 2 vats of chemicals to then mix to make a third..... I think!!!! Thanks so much if you can help!...

Ours are issued from the library too. It's their job to divy them out at the start of the year & collect them at the end. We are lucky! :) And I spose not all schools will want to go that way, so....... I think if you are going to charge a deposit then it has to be enough to encourage them to re...

Thanks Ev. That might be it! I have them on the sand in the same container as they grow (then they get put in an airy large one). I've been so worried about them getting buried but obviously I shouldn't. I recently started to let the leaves all accumulate on the bottom too. Thank you!

Hey guys, I'm having all sorts of trouble getting my stickies to live! When they do hatch, they keep getting their legs caught in their egg cases. I'm not sure if I'm the incompetent one or if it's them!! Any ideas? I was thinking that maybe I need to keep them more moist? I was also wondering if an...

Haha Waiting (barely!) patiently Macca

WOnder what colour they'll be..... wonder how big they'll be.... wonder how cool they'll look.... wonder.... wonder....

We make silver trees here on copper wire - an oldie but a goodie! And also not exactly the type but still fun!

One teacher asked me for my phone number so if he needed to know what stock we had over the weekend he didn't have to go into work!!



Another once wanted to know if we had any ovary boards. After a little 'Men from Mars Women from Venus' conversation I worked out he meant emery!!

Oh gosh, I'm so sorry to hear that Rosalie! Will keep you & your family in my thoughts. Take care. Kel

I'm Baaaack! Bet you didn't even know I was gone did you??!! :giggle: I've just finished my one-term teaching internship & am finally.... one of the OTHERS. 8O (anyone watch Lost?!!!) BUT I'm still lab teching & emergency teaching until a job (that I want!) comes up. I'm gonna be soooooooooo...

Thanks Trish, off to play now....

Hey gurus!

I recently made some borax (sodium tetraborate) star crystals & want to make more but I was wondering if it was possible to re-heat the borax solution instead of starting again & wasting it???

Any thoughts??

Cheers, Kel

Wow thanks guys! See you just proved my guru comment right!!

Will put the thinking cap on over the weekend & set up next week. I'm loving your ideas & website directions though.

Any others are still more than welcome - there's enough karma to go around.

Hey guys (my gurus!)

I've been asked to do a display for biodiversity month & am looking for some ideas....

We only have limited biological samples unfortunately (& hence me asking you guys!)

Much karma to everyone

Cheers Kel

Totally agreeing with you Rosalie M!

I think it would an amazing job but....... for the same reasons you gave...

Thanks Tori

Hi, I have some 11s making esters today & they need concentrated sulphuric acid. Does this mean the 18M???

Just seems very high (& dangerous)....

Hi Everyone, This is a LOOOOOOOOOOOOOOOOOOOOOOOOOOONGGGG shot but thought I'd try! When I go on pracs for my teaching course our school needs someone to do my 10 hour job - I work Thursdays normally & the rest of the time is here & there. I'm sure they would be pretty flexible with when you ...

Hi all,

I have a prac requiring Sodium oxide but can't find it in the old faithful supplier book.

Please PM me if you have a source!

Thanks, Kel

Hi guys, just a quick query. I know that contact lenses are very dangerous with chemicals. Sooooo do any of your schools ban students from wearing them during pracs? Or is it just suggested they don't? Also when kids have ordinary glasses - do you make them wear safety glasses? I know you should but...

Hey everyone :thumbup: I have a Food Tech teacher wanting to show the kids what effect washing hands has by scraping fingernails before & after.. you know the drill! I have found some great info on here about taping up the petri dishes & putting them into the incubator at around 30oC (or no ...
