In the last lesson, we explored ways to
measure rainfall.

We learned that you can
compare parts of the
weather only if the data is
measured in the same way.

Today we will focus on measuring temperature.

Thermometers are tools
for measuring temperature.
This one has two scales of
numbers: Fahrenheit (°F) on
the left, and Celsius (°C) on
the right.

In the United States,
meteorologists describe
temperature in Fahrenheit, so
that is the scale we will use.

Look carefully at the
numbers on the Fahrenheit
side of this thermometer.

The longer lines count by
tens and are labeled with
numbers. The shorter lines
count by twos and don’t
have numbers.

The top of the red area
marks the temperature.

The top of the red area
on this thermometer is
between 40 and 50.

To find out the temperature
shown on this thermometer you
can start at 40, then count by
twos up towards 50, until you
get to the top of the red mark.

When you do this, you will see
that the temperature on this
thermometer is 44 degrees
Fahrenheit.

Practice finding different temperatures
using these three thermometers.

What is the temperature
on each thermometer?

Find the Temperature Investigation:
Measuring with Thermometers page
and read the directions.

Watch a video of the
temperature investigation and
observe the thermometers.

You will complete this page
after you watch the video.

What temperature did you
record for each cup?

Which cup had the warmest water and which
cup had the coolest water?

How can you tell?

In the video, we saw the teacher use a thermometer to
measure the temperature of each cup of water.

Next, we will look at a
Temperature Benchmark. It
shows where different,
common things are at
different temperatures.

You will need a partner to
talk to in this activity.

Weather and Climate @Home Lesson 3

Your partner can be a family member, a friend or classmate on

the phone, a stuffed animal, or even a pet!

Talk with your partner about what you
imagine it feels like when it’s 93°F.

What does 93°F feel like
to you?

What pictures come to
your mind?

You and your partner might have talked
about what it feels like when it’s 93°F
and what you would wear.

You might have said it felt hot.
You may have pictured
wearing a T-shirt and sandals.
You might have imagined that
chocolate melts in your hands.

Most inside rooms like classrooms and
stores are kept at about 70°F.

What does 70°F feel like
to you?

What pictures come to
your mind?

40°F is about the temperature of the
inside of a refrigerator.

What does 40°F feel like
to you?

What pictures come to
your mind?

32°F is the temperature where water
freezes and becomes ice.

What does 32°F feel like
to you?

What pictures come to
your mind?

This is the end of the partner work in this lesson.

Weather and Climate @Home Lesson 3

In this lesson, we learned about how scientists measure temperature
with a tool called a thermometer.

One reason it is useful to use thermometers is
that it allows meteorologists and others to share
the same kind of data, so that they can compare
the weather in different places. We will be
learning more about this in the next lesson.
