Oh that makes more sense. I was imagining 175mm diameter and 490 height and knew that couldn't be right!

Does anyone have the Van der Graaf from MTA code SER1052222? I can't find a manual for ours either paper copy or online. Failing that, if you can find a model number or something on your machine I could try looking that up. I can't find one on ours...

Thanks!

Hi all

According to our inventory, we have these radiation cans.
Does anyone have these and can tell me what size they are as I don’t believe the measurements in the picture would be correct!

Thanks

Absolutely!

Hi All, Does anyone do virtual rat dissections on ipads/smartboards? Does the teacher still do a demo on a real rat? I'm just looking into possible alternatives. I was fairly impressed by a virtual frog dissection on a smartboard many years ago. If anyone could recommend apps that would be great! Th...

I've sent you a PM with my email address

That would be amazing! Yes please!

Hey so this is a very old thread - I was just wondering what is the current consensus on rats vs piglets and associated prices?

Any recommendations on where to buy rats (or piglets if they are better and the teacher agrees) in the Newcastle area?

Bigmack - I didn't have a sensor plugged in at the time! I did get a reply from the company. They suggested to make sure it's fully charged. Before I got that email though, I had tried a long press on the on/off button and that seemed to turn it off fully. I'm guessing a short press is like a standb...

Hi All, I have emailed the Data Harvest support but as they're in the UK I thought I'd ask here as well in case I get a quicker answer! The physics teacher (also new to this school) and I are trying to work out the data logger here. It's a data harvest easysense vision. When we turn it on we get a &...

Yeah my main food tech role is buying the ingredients and helping out in some of the classes (if I'm here those days) but it really isn't a massive part of my job. I am also wanting to have it in the RiskAssess schedule for myself so I don't forget to go shopping or can "tick it off" when ...

Yeah, that's what I was wanting - to have them on the schedule so Science staff can see that that there are other things going on. I didn't think about not signing off on the risk assessments. Does that mean I could just delete them later? I don't want to clog the system with saved food tech risk as...

Hey all! I know I'm not the only science and food tech labbie out there, so I'm wondering if anyone else has tried using risk assess to help with time management by adding food pracs to the scheduling. Is that possible without doing an actual risk assessment? I'm assuming not, but I don't want to 'r...

dead bat No-one had better bring me a dead bat shuddering at the thought of the disease & virus ridden bio bomb ocker. there was rum as well I was searching through the posts for the spread of disease pracs and came across this post. I bet nobody asks for dead bats anymore! Ewww.... (Edit: Afte...

Follow up on my previous post - I was looking up how to dispose of it when I found the amounts for use to make the carbon snake. (As far as I know, most teachers just do "about this much sugar" and add "about that much acid" and off it goes!). I thought I should try it in case ou...

I've found some dark brown Conc sulphuric acid here. It didn't react with sugar for the carbon snake demo (which is what I got it out for). Is it likely to be good for anything? There is probably about 1L of it.

Wow!

I added salt (probably a bit too much...) and an awful lot of blue food colour! It is a very dark blue ice block now

I find it interesting that the food dye moves to the middle of the ice instead of creating a layer at the bottom. That's what it did in my ice cream container as well! I'm sorry about your cracked beaker. :-({|= Thanks for doing the experiment though! :popcorn: :thumbup: Looks like I should add some...

Is it possible that the Blue was copper sulfate and not food dye . Cold filtering is a method used to separate particles out of solution .I guess thats what is happening when you freeze it . Swimming Carnaval today . Time for an experiment :D blue.jpg I'm sure if it was copper sulfate it would have...
