Obtain a temperature probe and connect it to the computer. Start the DataLogger software. Refer to
Technical Hints to see how to use the Data Logger software. Set the scale to 0 to 100 degrees Celsius. Set the program to run for 30 minutes.
Place 100 ml of chilled water in a cup of water. Let the probe record the temperature for 30 minutes.
While the probe is running, design a spreadsheet that records the types of cups found throughout all of the groups. Look at the sample set of cups at the front of the room to determine the headings. Refer to
Technical Hints to create a spreadsheet.
In your group first, observe and record all the differences in the cups. Next, discuss and predict what will happen to the temperature of the cold water in the plastic, paper, and Styrofoam cups.
When the temperature recording is finished, enter the data into your spreadsheet by directly transferring data from the DataLogger program to your spreadsheet. Refer to
Technical Hints to transfer data to the spreadsheet.
Answer question 1 in the "Analysis".
By sharing computer disks between groups, add the data from each group that used another kind of cup to your spreadsheet. Ask your teacher to see how to save and share your data.
Create a x-y line graph for all of the data for each kind of cup. Refer to
Technical Hints to create a x-y line graph from your spreadsheet. Your graph will have a line for each kind of cup.
