1. assess what students already know about the two temperature scales (Celsius and Fahrenheit)Pairs of students will:
2. provide additional information as needed
3. emphasize that most of the world uses Celsius
4. discuss temperature doesn’t mean anything if it is in an unfamiliar scale
5. show formulas for converting Celsius to Fahrenheit –F= (9/5)C + 32 and Fahrenheit to Celsius – C=5/9(F – 32)
6. suggest estimation could provide a meaningful temperature (Round fraction to nearest whole number and 32 to the tens place. Use the adjusted formula to get an answer that’s close enough for everyday life.)
7. remind students that scientists need an exact answer. Instead of entering the formula for each conversion we can program a graphing calculator. Instructions will be given for writing a short program and for using lists.
8. Provide world maps so students can select cities in different areas of the world.
1. obtain But What Should I Wear?? worksheet, Conversion Methods handout and a graphing calculatorSuggested websites are:
2. search the Internet to find today’s forecast in Celsius for selected cities. Enter on worksheet.
Weatherlabs (note: click for metric along left side)
Accuweather (8 continents/regions are given - pick country and city and switch to metric at bottom of screen)3. estimate the equivalent Fahrenheit temperature. Enter on worksheet.
4. follow the instructions page to calculate an exact conversion. Enter on worksheet.
5. answer the question in the last column for each city
2 – Pair wastes little time. Data is obtained as instructed, but conversions or questions are slightly incomplete or not done as instructed.
1 – Some data is obtained and some parts of conversions and questions are completed.
0 – Majority of assignment is incomplete. Internet time is used incorrectly.
