Measuring Temperature
Part 2
Daily Objective
Temperature describes how hot or cold
the air is.
Temperature is measured with a
thermometer.
The unit used to measure temperature is
degrees Celsius ( C ) or Fahrenheit (F).
Vocabulary
 Temperature - A description of how hot or cold something is
 Thermometer - A weather instrument used to measure
temperature
 Weather instrument - A tool that helps meteorologists
measure weather

 Freezing - An air temperature below 0°C (32°F)
 Cold - An air temperature between 0°C and 10°C (32°F and
50°F)
 Cool - An air temperature between 10°C and 20°C (50°F
and 65°F)

Introduction
Today we are going to we are going to learn
about measuring temperature.
Temperature describes how hot or cold
something is. We can measure the
temperature of different things.
Observations and Discussions
Measuring Water Temperature

temperature
when the temperature is warmer.
What do you think will happen to the red
line on the thermometer if we put it cold
water? In the hot water?
Make a Model Thermometer
1.
Color the areas as follows:





Hot – red
Warm – orange
Cool – yellow
Cold – blue
Freezing – purple
2.
Cut out the glass and bulb (red line). Fold the paper in half so
the picture is showing. Make a small cut in the middle of this
area, open up the picture, and cut out the entire glass and bulb.
3.
Turn the thermometer picture over and spread glue along the
long edges. Do not glue the short edges.
4.
Place the glued side of the thermometer picture on the white
piece on construction paper. The picture is slightly smaller that
the construction paper, so edges will not match.
Insert the red strip of construction paper between the
thermometer picture and white construction paper. You should be
able to move the red strip.
5.
Measuring Air Temperature
Indoor vs Outdoor
Now lets compare the indoor temperature to the
outside temperature.
1. Guess. Do you think it will be the same or
different?
2. Read the thermometer for the indoor
temperature and set your model temperature.
3. Go outside for the outdoor temperature.
4. Compare the two temperatures. Was it the
same or different?
