Nowadays this is the thermometer that is widely used around the world. His thermometers always have a‘ C’ so people would understand that this is his invention. Let’ s see does our thermometers have the same markings?
I have here many different thermometers, let’ s see why are they used for. Let’ s see what the thermometer is made of and what parts does it contain. Thermometer has a scale of numbers, then there is a container of liquid and a small glass pipe where is possible for the liquid to move up and down. When the liquid gets warmer it will expand and move up the small glass pipe, when the liquid gets colder it decreases and moves down the glass pipe. Tools: Thermometer, 2 jugs for hot and gold water. Experiments: First the kids will get the thermometers and will observe the room temperature. For the next step they will put the thermometer in to the cold water and they will see the liquid starting to go lower as it decreases inside, and then they will make the same experiment with the hot water and see the thermometer go up. Tools: Small pictures of sun and moon. Small items for counting. Test: Sunday morning thermometer was showing + 3, in the day time the sun was up and thermometer went up for the evening + 6. How many degrees did the thermometer rise?( Kids will count and set up the morning and the evening result of the thermometer, they will make comprising and will find a solution) Test: Monday morning the temperature was + 5, it was raining it the daytime and in the evening the temperature was risen + 6 degrees. How many degrees did the temperature rise? Etc.
