Twelve student thermometers at $3.60 each - but read the temperature limit first
12 thermometers, -40 to +50 degrees C, roughly 15cm long. Glass tube on a PVC backing. Mercury free. Ages 6+.
The limit is 50 degrees C. These cannot go in boiling water, or in hot water from a kettle, or in a beaker over a bunsen. The supplier says so plainly and so do we, because a pack of twelve broken thermometers is an expensive lesson. If your class is heating anything, buy the red spirit lab thermometers instead, which read to 110.
What these are for is everything below body temperature: the room, outside the window, a glass of water in the fridge, ice melting, the difference between the shade and the sun. That is most of primary science and a good deal of early secondary.
The plastic backing is what makes them work with young children. It is a flat card with the glass tube fixed along it, so the thing has a shape, it does not roll, a child can hold it without pinching a bare tube, and it can be left standing in a beaker or stuck to a window and forgotten about.
Twelve is the number that changes the lesson. One thermometer is a demonstration; twelve is every pair of students taking their own reading and finding out that measurements disagree - which is the actual lesson.
