Funny you should say that. This morning I Tried to turn the tap on a burette and it

snapped off cutting the top of two of my fingers. I'm glad I tried and not one of the students. So I am interested in the solution as well.

Thanks guys this has been a hilarious read. Keep up the good work Slartibartfast you crack me up. WD40 will never take over from the good old blue stratus in the aftershave stakes, Sorry. Men; they are so out of touch.

Oh I hear ya pkij. That happens often to me and yes 8 times out of 10 its the HOD. In fact I sent out a reminder email only last week stating a few of my rules eg. Giving 24 hours notice, letting me know when pracs are finished with etc. I have to admit they have been worse since the email went out....

I had this one today, "I am just feeling my way with this class and they just love doing pracs, Sorry about the short notice but I will get organised one day, thanks so much I appreciate it".

At least she thanks me.

Hi All Wow. I dont feel so bad now my budget just for equipment and chemicals is less then $1000. (We have approx 740 students.) That dosent include text books or anything. But still it is a stretch when I continually get broken glassware that needs to be replaced. Anyway thanks for your replys its ...

Hi Guys After attending a Labbies PD day on Friday I discovered, after a general chitchat, as you do, that my budget for equipment and chemicals was very low compared to other schools in the region. So I thought I would get an all over Australia consensus and ask my fellow labbies what their budgets...

Hi

I make my solution up as follows:

180gm D-Glucose per litre H2O

So breaking it down you probably need 22.5gm per 125 ml H2O.

Hope that helps.

Hi Just out of interest how does everyone receive their prac requests? Here the labbie before me created a program in Access to handle all scientific requests. The program is a database of all existing experiments done at the school. All the teachers have to do is look up the particular experiment a...

Hi all

The teachers do the risk assessments here also. They provide a risk level number on
each prac request; 1 being the lowest risk etc. Its all in the hands of the teachers.

All prac sheets are filed after they are finished with.

Hi Liz

What a great idea. I too was thrown in the deep end and struggle often to find things, make things, name things (especially physics equipment).

I am going to take a leaf out of your book and do the same as you. I will start today.

Thanks Nicky

Hi Sue I do clean the classrooms. The teacher puts a note in the prac tote box saying either "finished" or "leave until p3 on Thursday" etc. If there is no note I will ask the teacher via email if they have finished, they are usually pretty good. I clean all the sinks on Fridays ...

Your a gem Jazz thanks heaps.

Nicky

Thanks Jazz and Lisa, I am new to this game and I panic when I cant find recipes for the solutions. I didnt know whether the salicyclic acid had to be mixed with water or something else like ethanol. So Carol the reason I wanted to know how to make the solution up was because it didnt dissolve very ...

Hi

This is probably a really lame request but can any tell me how to make
0.1M Salicylic Acid, Abscisic Acid and Ethylene I cant find the recipes anywhere.

Thanks for your help.

Hi Kristin,

What a great idea! Townsville too has its fair share of crocodiles and our school is right next to a creek/river. I wonder if anyone will miss the little darlings.

Have a good long weekend.

Hi

We have used hibiscus leaves before only because there is a large plant right outside my office window. Very handy, it also has good results.

Hope this helps
