Re: Wireless Data Loggers
NeuLog from Westlab are reasonable. You have to connect a battery and a WiFi box and then the students can download a program and connect up. When you use them connected with a laptop you need to ensure that the laptop doesn't 'sleep' as there are some problems when the computer 'wakes up' and don't...

Re: Potassium Permanganate crystals
They used to use it to help heal horses' hooves (as in All Creatures Great and Small). It had its uses but antibiotics have taken over! mmm, not sure if that is such a good thing.

NeuLog data loggers
Has anyone had experience with NeuLog data loggers, especially with Macs. I am having trouble changing 'experiment setup'. Some work, some don't. Any ideas???

Re: Induction Motor Experiment
I have inherited something similar, but with four electro magnets. You hook it up to an IEC Wave Lab (the one with two signal generators) and put them out of phase by 90 degrees and connect them up to the electro magnets ( east - west out of phase with north - south ). Works a treat and when you cra...

Re: Partical Theory
These might be the sort of things you were after for Particle Theory as a starting point. I used those small black plastic boxes from electronic suppliers. Wagners have them very cheap. The kids have to guess what is in them and so work like a scientist putting forward their theory of particles. MYS...

Re: Natural Gas
Have you got new wire mats? We have, and they stink at first heating. Could this be the cause?

Re: Laboratory decorations
I've googled Science images, cut and pasted into Publisher so that they take up roughly half an A3 page (landscape) usually 4 images per page, got them printed, cut in half and laminated. Makes a nice border. My improvement would be to print onto light card to eliminate the glare from the laminating...

Re: pH meter
These are the ones from Westlab. You are supposed to scoop ups few drops and then take your reading. You need to be GENTLE!!!

Re: pH meter
The pH meters are easy enough to use. but the actual sensor can be broken fairly easily. Cleaning is a problem in that if you aren't careful the sensor can be damaged. Use it as a demo??

Re: Endothermic Reaction Prac
A simple one is citric acid and bicarb. Form a slurry of one and mix in the other! The more the merrier, but it works in small quantities.

Re: Mineral and rock safety alert
At the end of last year I heard the Catholic sector was spraying all the boxes with a dilute solution of PVA glue and disposing of the most likely rock samples. Not sure if it caught on!

Has anyone had experience with non contact thermometers? Are the ones with a laser sight safe to use?

Re: CD Hovercrafts
If you Google something like "CD hovercraft" you should get the instructions and videos. Basically you glue the bottle cap to the centre of the CD (this allows you to control the flow rate), put a blown up balloon over the top, then let it go!

Hi Rita,
I have seen them at Reverse Garbage at Marrickville - a bit far from you but you might have a similar recycling/reuse place nearby??

Re: Glass tubing
Have you tried using liquid soap or glycerine as a lubricant? Use a LARGE rag or towel to hold the tubing. It is hard to recommend tube sizes - it depends on what you are connecting at both ends e.g. side arm test tubes vary in the size of the arm.

There are digital versions of ammeters and voltmeters. Only used the ammeters and they seem fine. Might need to buy up on batteries!

absolute zero demonstrator
We have one of these - bulb connected to a long tube with a pressure release valve and a pressure gauge at the top. The gauge goes from -100kPa to +300kPa. Has anyone ant idea of where I would get a replacement gauge? Serrata doesn't!
