Title: Fahrenheit/Celsius Temperature Conversions Objectives Students will understand that there are two temperature scales used in the world, and that in some occupations in the U.S., conversion between the two is necessary. Students will be able to convert Fahrenheit to Celsius temperature, and vice versa, and complete a worksheet with 80% correct. Time frame to Complete 60 minutes NRS EFL 4 S ta ck ab le C er t.

Materials Worksheet with answers available from http://www.math-drills.com/measurement.shtml (attached) Pencil Calculator computer with Internet access for extra work Learner Prior Knowledge The student should have a command of addition, subtraction, multiplication, and division. The student should have basic knowledge of temperatures, such as body temperature, freezing and boiling points of water, etc., in Fahrenheit and Celsius. Activities Step 1 Teacher explains that there are two main temperature scales -– Fahrenheit (used in the U.S.) and Celsius (used in most other countries). They use different numbers to measure temperature. Teacher writes °F and °C. Step 2 Teacher states that the Celsius scale is based on the freezing and boiling points of water (0°C and 100°C). These two points are equivalent to 32°F and 212°F. Most measurements in medicine use the Celsius system. Pharmacy technicians may need to convert between the two systems. Fire rescue and welding personnel may also need to use both scales. Step 3 To convert between the two systems, these equations are used: To convert Celsius to Fahrenheit, use: (°C × 9/5) + 32 = °F To convert Fahrenheit to Celsius, use: (°F - 32) x 5/9 = °C Step 4 Teacher writes several problems on board, shows steps to solve. Class does 4 problems together: a) Convert 25°C to °F Answer: 77°F b) Convert 90°C to °F Answer: 194°F c) Convert 86°F to °C Answer: 30°C d) Convert 115°F to °C Answer: 46.1°C Step 5 Teacher distributes worksheet and encourages students to do 20 problems, and, if time permits, continue on to complete all of the problems. Answer sheet will be distributed during last 15 minutes. Worksheet problems taken from the following website: http://www.math-drills.com/measurement.shtml http://www.math-drills.com/measurement/convert_between_celsius_fahrenheit_001.pdf Assessment/Evidence Teacher monitors students as they work and checks for understanding. 80% correct shows mastery of concepts. Student will have comprehension of Celsius and Fahrenheit thermometers. Put students’ completed papers in portfolio to demonstrate mastery of benchmarks related to the Basic Skills Stackable Certificate. Adaptations for Beginning Students Teacher checks for understanding and gives one-to-one instruction and additional problems. Have beginning students work with a partner. Adaptations for Advanced Students Advanced students could be encouraged to complete the entire worksheet. Students can also be directed to the following website of temperature conversion problems: http://www.mathsisfun.com/temperature-conversion.html Teacher Reflection/Lesson Evaluation Some students have been challenged by math. Re-teach and re-teach it, if necessary. Try to make it fun. This lesson was created by Middletown ABLE.
