Productive Question 1.why does our country use celcius scale for measure temperature?

Evaluation 1.what is the definitions of temperature? 2. Compare Celsius scale with the Fahrenheit scale, Kelvin scale and reamur scale: 25 °C = ……°F = …… ……°R = …………K 40 °R = ……°C = …… ……°F = …………K 152 °F = ….....°C = … ………°R = …………K 273K = ……°C = …… ……°R = …………°F 60 °C = ………..°R = … ……°F = …………K

Main activity 15 minutes 1. Ask what is temperatur? 2.Guide students to find the right definition of temperature. 3. Ask how many kinds scale of temperatur and mention it? 4.Introduce many scale of temperature and also their range. 5.compare between any scale of temperature. 6.make an example question and ask the student to answer it. 7.give reward to the student which can answer the question. Closing : 10 1. together make a conclution about this matter. 2.give an individual task to the student as a reflection.

Temperature and Thermometers Temperature Temperature is how hot or cold something is. Temperature is really a measure of how fast the atoms and molecules that make up a substance are moving (this movement is sub-microscopic; you cannot see it).

Thermometers Used to Measure Temperature A thermometer measures the temperature of something, showing how hot or cold it is. There are many different types of thermometers that measure the temperature of different things. We use thermometers to measure the temperature of the air, our bodies, food, and many other things. There are analog and digital thermometers. An analog thermometer shows the temperature on a scale or dial; a digital thermometer shows the temperature as a number. The higher then number above zero, the higher the temperature.

Temperature Scales Temperature is measured in many different scales, including Fahrenheit, Celsius (or Centigrade),Reamur and Kelvin scales. The units of the Celsius,Reamur and Fahrenheit scales are called degrees; the units of the Kelvin scale are called

kelvins. The symbol for degree is °. A change of one degree of temperature Celsius is the same as a change of one kelvin; a change of one degree Fahrenheit is a smaller change in temperature. Each temperature scale is useful for diffferent things. Fahrenheit is a measure of temperature that is abbreviated F. Water freezes at 32°F and boils at 212°F. This scale was developed by Gabriel Daniel Fahrenheit in 1714. The Fahrenheit scale is used in the USA but not in many other countries. The degrees in Fahrenheit are smaller than those in Celsius, making weather-related temperatures more easily written (without having to use a decimal point). Celsius (also called Centigrade) is a measure of temperature that is abbreviated C. Water freezes at 0°C and boils at 100°C. This scale was developed by Anders Celsius in 1742. Kelvin is a measure of temperature that is abbreviated K. Kelvin is a temperature scale designed so that 0K is defined as absolute zero, and the size of one unit is the same as the size of one degree Celsius. [Absolute zero is a hypothetical temperature at which all molecular movement stops. All actual temperatures are above absolute zero. Absolute zero would occur at -273.16°C, -459.69°F, or 0 K.] Water freezes at 273.16K; water boils at 373.16K. Many scientists use this scale (because all the temperatures are positive, making calculations simpler) or the Celsius scale. This temperature scale was designed by Lord Kelvin (William Thompson).

Conversion Formulas If you know the temperature in one temperature scale you can use a formula to figure out what it is equivalent to in other scales. The conversion formulas are in the table that follows. Celsius to Fahrenheit (and Fahrenheit to Celsius):

Kelvin to Celsius (and Celsius to Kelvin): C = K - 273

F = 1.8C + 32 K = C + 273 C= (F - 32)/1.8 (A degree Celsius is 1.8 times bigger than one degree Fahrenheit.)

(Converting between Celsius and Kelvin is easy because the size of a degree Celsius is the same as the size of a kelvin.)
