A brilliant and very simple idea shared with Positive Eye by a creative Teacher of VI from Samuel Cody Specialist Sports College. This is an ingenious idea to teach the concept of how a thermometer works.
The thermometer is made from a yellow bead threaded onto a length of dowel, mounted on a board that is painted.
The red/blue bead at each end of the dowel is a square wooden bead, drilled through to screw everything in place.
The numbers are mounted on a strip of fridge magnet so that you change them to suit your topic. For example, you could make the scale go from 0 to100, -10 to +10, use decimals, etc.
