As a result of the lesson students will be able to solve multiple step    equations involving addition, multiplication, and division.2. As a result of the lesson students will be able to convert a known    temperature in celsius to an equal temperature in fahrenheit.3. As a result of the lesson students will be able to accurately read a    thermometer in degrees celsius.Materials Needed:1. 6 thermometers in degrees celsius2. 1 cup of hot water3. 1 cup of regular water4. 1 thermometer in degrees fahrenheit5. calculators for each studentStrategy:I opened my lesson with a short story.  The story talks about me driving to my doctors office on a hot summer day trying to figure out if the temperature had reached 100 degrees fahrenheit.  As I drove around all I could see were temperature readings on banks in degrees celsius.  Eventually I arrived at my doctor's office.  As we talked about the weather we both began to wonder what the temperature was outside.  I told him that the bank signs all showed 39 degrees celsius.  However, a temperature in celsius does not really tell us if it is 100 degrees fahrenheit.  Thus we have created a problem that we need to solve.  Is 39 degrees celsius about 100 degrees fahrenheit?  Now you can present the formula developed by Anders Celsius in 1742.  The formula says that if you know a temperature in degrees celsius you can convert it into degrees fahrenheit by: F=9/5(C)+32.  To check and see if this formula works, we will convert the known temperatures at which water freezes, 0 degrees celsius, and at which water boils, 100 degrees celsius.  They should convert to 32 and 212 degrees fahrenheit respectively.  Students will then convert 10 celsius temperatures to fahrenheit in their cooperative learning groups. Remember to follow your order of operations when solving these problems.  Have students go to the board and explain their answers. Introduce students to the 6 different stations.  Each station has a thermometer in degrees celsius.  Station 1 is outside, station 2 is in the back of the room, station 3 in the front of the room, station 4 in the hallway, station 5 in a cup of hot water, and station 6 is in a cup of regular water.  Ask students to predict which station is the hottest.  Then list them from hottest to coldest. Now allow students to travel to each station and record the temperatures at thestations in degrees celsius.  While waiting to go to the next station, studentswill convert temperatures to degrees fahrenheit.  After all groups have been to each station confirm whether or not everyone has the same answer.  Then see how many people made the right prediction.  After checking predictions and answersuse your fahrenheit thermometer to check the temperature of the hot and regular water.  You should come out with fairly accurate numbers.To close this lesson you can take a briefcase with a three digit combination and place it in front of the class.  Tell them that you forgot the combination, but you remember that you set it on a day when it was ___ degrees celsius.  If they can convert this temperature to degrees fahrenheit, they will have the combination.  Let students work in their groups and come up with their answer. Give each group a try.  Performance Assessment:1. Students will read the temperature of 6 different thermometers in degrees    celsius.2. Students will convert 6 temperatures in degrees celsius to degrees fahrenheit    by using a formula.3. Students will solve multiple step equations involving addition,    multiplication, and division.`
