PERFORMANCE TASK STUDENT RESPONSE FORM
TASK: S1 - TEMPERATURE SCHOOL
Grade 4
Student Name: _______________________________________________
School Name: _______________________________________________
School Code: _________
GENERAL INSTRUCTIONS:
Write your name, school name, and school code on the line above.
Do not open this packet until the directions tell you to do so.
You will have a total of 45 minutes to complete this task. You may
use up to 30 minutes to complete the group work.
GROUP ACTIVITY:
Did you ever drink a cup of "hot" chocolate that was no longer
hot, or a "cold" cup of milk that had become warm? In this activity,
your group will study how liquids change temperature. You will measure
the temperature of hot, cold, and room temperature water as time
passes and make tables so you can study your data.
- Practice using the timer. It is made so that it takes just 3
minutes from the time it is turned over for the sand to run completely
from one end to the other. You will use the timer to know when
it is time to read the the thermometers. Name one person in
the group as the "time keeper" who will use the timer. The
others will be busy reading the three thermometers and recording
the results in their tables.
- Set up your experiment as follows:
- Use the measuring cup to put-
- 1/2 cup of room temperature water in Can A
- 1/2 cup of hot water in Can B
- 1/2 cup of ice water (only water - no ice) in
Can C
- Place one thermometer in each of the cans.
Your group is now ready to collect data that will be written in
the table. You will read the temperatures of the three cans of
water every three minutes. It is very important that once you
start, you keep going. You must keep measuring the temperatures
every three minutes for fifteen minutes.
- Do the following things in order:
- Have the time keeper turn over the timer. Then, as quickly
as you can, read all three thermometers without taking
the bulb out of the water. Write the results in the first
row in the table below.
- When the sand has run out, three minutes will have passed.
The time keeper should then say, "Time", and immediately turn
the timer over again. As before, the others will read the
three thermometers as quickly as they can and write the results
in the table.
- Keep repeating this process each three minutes until
15 minutes have passed and you have completed the table.
- Make sure that each person in the group, including the time
keeper, has had a chance to complete the table, and that each
table is the same. Then pour the water from the cans into the
waste container and dry things with the paper towels.
When you finish the work on this page, someone should tell the
person in charge that your group has finished its work.
INDIVIDUAL ACTIVITY
- Use your data table to help you describe what change, if any,
you observed in the temperature of the water that started at room
temperature. Tell why you think this happened.

- Look at the columns in the table for hot water and cold water.
Describe what seemed to be happening to the temperature of the
hot and cold water as time passed. Tell why this was happening.

- If you kept measuring the temperature of the three cans of water
for a whole hour, tell how the three temperatures would compare.
Write down what you think the three temperatures would be after
an hour.

- Suppose you put a cup of hot chocolate down because it was too
hot to drink. You started to watch a TV program, and forgot your
hot drink for one hour. Use the results of your group experiment
to tell what would have happened to the temperature of your hot
chocolate.
