Laboratory thermometers are capable of accurately measuring temperature variations in a variety of mediums, including some caustic to human skin. Keep in mind that Galileo thermometers are not super precise. We can recall, when somebody in the family suffered from fever, the temperature was measured by a thermometer. Now we know that for any scale, we need the two reference points. Copyright 2020 Leaf Group Ltd. / Leaf Group Media, All Rights Reserved. Kids will read the pictured thermometer, then circle the correct temperature or write it themselves. The clamp has two ends: The first is a rubberized end that will hold the thermometer, and the other is a C-shaped end with a bolt through it. Interpret the readings. Typically, laboratory stands are of simple construction, with a thick, heavy base (usually of metal) and a long, thin bar extending upward. The expansion of mercury due to heat is what tells us the temperature. Note the temperature difference that is indicated between two bigger marks. Below you will find the formulae for its conversion; Wash the thermometer with water at normal temperature. Outside the bulb is a small shining thread of mercury. Attach the thermometer. An object’s temperature shows how much heat it has. Reading a Thermometer: Steps: Wash the thermometer with water at normal temperature. Appreciations are sincere and specific, and there are a lot of different purposes to it. Let’s check the thermometer. To accurately use and read a thermometer to measure water temperature. Temperature of the body is measured using a clinical thermometer. Hold the thermometer horizontally so you can read the numbers. For example, if you are testing the temperature of ice water, place the reservoir in the water, below the ice, but not touching the bottom of the flask or cup the water is held in. Keep the thermometer under the arms or tongue in order to get the reading. In order to find the exact measure of this hotness, the concept of temperature was introduced. This first-grade resource fits well next to Earth and space science topics. Keep the thermometer under the arms or tongue in order to get the reading. The key is to not hold the thermometer in your hands because your hands will warm it up and give a skewed reading. Science; Social Studies; Holidays and Events; Support; Worksheets > Math > Measurement > Temperature > Reading Thermometers; Reading Thermometers Worksheets. Bring the thermometer close to the eye as shown in figure below in order to see the precise reading. Before using see that the temperature falls below the 37⁰C mark or the 98⁰F mark, the ideal human body temperature. Bring it up to eye level with the end of the liquid right in front of you. the bigger mark reads 10. The temperature sensors are so calibrated that the numbers on the thermometers represent the temperature of the body. Because of their construction, and their expense, it is important to know how to properly use a lab thermometer without breaking it. These jerks help to bring the level of mercury down. Download Worksheet View answers Add to collection Assign digitally. Relevant periodic markings of degree units will also be present on the thermometer.

On the Fahrenheit scale, this would turn out to be \(212^{\circ}F\) for the boiling point and \(32^{\circ}F\) for the melting point. Before using see that the temperature falls below the 37⁰C mark or the 98⁰F mark, the ideal human body temperature. Prepare students of grade 1 through grade 4 to read temperatures on Celsius and Fahrenheit scales from a large variety of temperatures recorded on our … Look for the long lines, which indicate 1 °F (−17 °C) each and the smaller lines, which indicate 0.2 °F (−17.7 °C) each. Your email address will not be published. What you have to do is simply look at the lowest ball that is floating while … When teaching kids how to read a thermometer, it is important to also teach them why it is important to know how to read a thermometer. Attach the clamp to the stand. A thermometer looks like the one shown in the above figure. But we cannot always depend on our sense of touch to find out whether the object is hot or cold, as one may get hurt while touching a very hot object or the object may appear to be hot in one circumstance and relatively cold in the other. Stay tuned with BYJU’S to learn more about heat energy, thermometer and many more. If we calculate the expansion of mercury per degree change in temperature; then we can calibrate the thermometers with a scale based on the expansion.
