Math teachers are always wondering on how to use real world problems in any mathematical lesson. I think that a good way to do this is to do something that will get the attention of all students and do something they can all engage in. For this assignment we will be using the LabQuest2 and two temperature probes to measure the temperature of a cup of hot water using both Fahrenheit and Celsius.
This will be done by connecting the two temperature probes into channel 1 and 2 of the Labquest2. The students will then turn it on and go to the home button. They will then select the red temperature and make it Celsius and select the blue temperature and make it Fahrenheit. Once they do this they will get the cup of hot water
and insert the probes inside then they will select the green arrow that will be shown on the bottom left hand corner of the screen to collect the temperatures for both Celsius and Fahrenheit. After 1 minute the students will stop the collecting the data by pressing the red rectangle. Then they will go to the analyze menu and select curve fit. Then they will select the red temperature and then click linear and write down their regression equation on the worksheet handed out to them for Celsius and then repeat for the blue temperature(Fahrenheit). The students who will be in groups of three will compare and contrast these temperatures graph them both on a piece of paper and then form a linear equation for both of the different scales. Then the students will use the information to tell whether the equations are the same, parallel, or intersecting and if they intersect where?
