Each one is a basically a Rheostat. You need two to make a wheatstone bridge .
Could do same thing with normal Rheostats .

probably someone that appreciates Steampunk stuff would love them Where would I find such a person? (Or is that a joke that flew over my head??) Not a joke Rosalie. Steampunk is quite a passion for some folk . They love old school Wood,brass,copper Leather etc . Some are quite artistic with it . No...

Is it these things Rosalie ? .
Dragged out from the back of the Physics cupboard. Couple of variations , but they all do the same thing . There's a piece of Nichrome wire on the ruler . No ones ever asked for them while I've been here

I have a B/W laser printer in Staff room which is a reasonable walk but most of the time I'm needing Colour stuff and have to walk 4 flights of stairs and the other side of the school . I have to ring the Printroom , see if they are using the Colour printer and then make sure the Bypass tray is not ...

I had dozens and dozens of them Rosalie. I'd attempt to clean them when I had a chance .A year later they were mostly still there . Sometimes you just gotta do what you know you really need to do . :thumbup: I binned them and bought new ones \:D/ Well actually , I kept a few of the better ones for N...

We do this for Year 7 Taster Day - students get one of each to see which works the best.

I like that idea Merilyn

Thankyou so much Labby
I'm off to the shops

I've been asked for teabags to do the Tea bag prac. You remove the staple , empty the bag , form it into a tube and light the top .It sits there for a while and slowly lifts off the bench . Now last time I got tea bags but they had no staples and even though they carefully cut the top and bottom off...

A smear of Silicone grease on the tapered lids usually stops this happening .It lso stops the lids fusing on .

I'm guessing you are talking about metal plates, grills etc They can just go into scrap metal bin if you have one .
If you also have the Wax prisms and lenses, can't see any issue with putting in general waste.

As far as the transmitter/ receivers go , it's just e-waste .

Thanks Rosalie.
Personally I like the idea of petri dishes and essential oils . It would take up less storage space .
I may look at switching some of mine to what you are using . The Camphor smell is really strong and tends to overpower the others ,especially if left uncovered for too long.

Was packing these up and thought I might share . These were something I was asked to make a few years ago .At the time I thought it was a bit lame , but they have been used over and over .There are four of each . One is a tactile feel box . It has four holes that kids stick thier finger in and expla...

Hope I am not out of line posting this .I trust you will delete it Labbie if you feel it is breaching DOE confidentiality .

My head teacher says that Primary Schools are not allowed to do experiments with anything that's not edible . So using Metho is a breach straight up .

Which could explain why so many year 7 kids are always asking if they can eat everything .....to much molly coddling

We don't have it but I would agree with class 8.

Great point Alice . I should have stated that that chart was for Chem supply Universal .

By the way , the stuff you sell covers a larger range .Looks good
