Starter: Write down the equation and then solve for the triangle!
Rewrite the following formulas in terms of the specified variable:
1. A = lw, for w
2. A = 1/2bh, for b
3. A = 1/2 bh, for h
4. C = 2∏r, for r
There are only 5 countries in the world that still use Fahrenheit to measure temperature:
1. The Bahamas 2.Belize 3. The Cayman Islands 4. Palau 5. The United States
Sometimes it is more convenient to rewrite a formula in a different form. For example, the formula for changing degrees from Fahrenheit to Celsius is: F = 9/5C + 32. If you are told the temperature in London, England is 18 degrees celsius how much is that in Fahrenheit?
Now what if you move to France and want to make recipes in your oven that is set to Celsius? How do you convert all your recipes in your American cookbook to Fahrenheit?
____________________________________
Would it be easier to come up with a new formula? Try it!! Hint: try to get C by itself.
C =5/9 (F­32)
There are three countries that do not Primarily use the metric system:
1. Burma 2. Libera 3. The United States Temperature Group Activity:
1. Choose a recipe card. 2. Write down the food item corresponding to the card on the top of your paper.
3. Choose a country that uses celsius.
4. Divide your paper in half lengthwise to make two columns.
5. Write your country's name on the right column.
6. Write "U.S.A." on the left side.
7. Convert the temperatures to the correct unit of measurement, showing the conversion formulas in both columns.
8. Calculate the temperatures at which you will cook/bake your recipe.
9. Draw and color a picture of your recipe.
10. Write your names on the BACK of your paper.
11. On the front, write an interesting fact about your recipe.
Concept Check:
Polar stratospheric clouds are colorful
clouds that form when temperatures fall
below -78 degrees celsius. What is this
temperature in Fahrenheit?
