Using the thermometer with the correct technique
AIM
to measure the temperature of water.
APPARATUS AND Beaker, thermometer, tap water, hot water,
MATERIALS and cold water.

STEPS

1. Place the beaker on the table 2. Immerse the thermometer into the
and pour 250 ml of tap water into beaker. Ensure that the bulb of the
the beaker. thermometer does not touch the
bottom surface of the beaker.

3. Wait until the liquid level in the 4. Repeat steps 1 to 3 using hot water
thermometer becomes constant. and cold water.
Measure the temperature of the
tap water at the correct meniscus level.

5. Record the observations in the table 6. Construct a bar chart using the data
as shown below. in the table.

7. Report the results of your group’s activity.

(a) Explain the correct ways to measure the temperature using
a thermometer.
(b) Compare your bar chart with other groups.
(c) Predict the temperature of the tap water if it is mixed with ice.

Identify the thermometers as shown in
