Remember, we are
meteorologists who are
helping find the island with
the best weather for
orangutans.

Read the message from the
Wildlife Protection Agency
on the next slide.

This report shows
temperature and amount
of precipitation for one
day on each island.
Remember, orangutans
live in some of the
hottest and rainiest
places on Earth.

Let’s focus on the data in the
precipitation column.

Weather and Climate @Home Lesson 2

You can see that on
these islands rain is the
only kind of precipitation.
It isn’t cold enough for
hail, snow or sleet.

Carefully look at all data in the Island
Weather Report.

Can you tell which island
is hottest?

Can you tell which island
is rainiest?

Weather and Climate @Home Lesson 2

You probably thought it
was hard to tell which
island is the rainiest or the
hottest using this data.

Next, you will talk with a
partner and discuss why
it would be so hard to use
this data.

Weather and Climate @Home Lesson 2

When we think about how things are alike or different,
we are comparing. When we think about which island is
hottest or rainiest, we are comparing the islands.

When we compare the places orangutans live to these
islands, we are comparing so we can find the best island
for the reserve.

You will need a partner to discuss the island data with.

Your partner can be a family member, a friend or

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

What makes it hard to
compare the weather on
these islands?

What would make it
easier to compare the
weather on these islands?

How can meteorologists describe weather in
a way that helps them make comparisons?

Weather and Climate @Home Lesson 2

It is difficult to compare the weather on the
different islands. To help us compare the data,
we are going to investigate this question:

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

We will investigate rainfall by measuring the
amount of rain that falls in two places.

We want to discover if we can describe the
amount of rainfall so meteorologists can
compare precipitation amounts in two places.

Weather and Climate @Home Lesson 2

We will observe a rain cup
with holes in the bottom
to make it “rain” over two
different “places,” Cup X
and Cup Y.

Weather and Climate @Home Lesson 2

We will observe these tools being used
to measure the rainfall in the cups.

How might you use one
of these tools to measure
rainfall?

Find the Measuring Rainfall page and
read the directions.

Watch the video of a
teacher measuring rainfall.

You will complete this page
after you watch the video.

best measured the

Can we compare data
from two different tools?
What makes it difficult?
What makes it easier
to compare data from
one tool?

Weather and Climate @Home Lesson 2

It is very difficult to compare
data when you measure
using different tools.

For example, it would be
difficult to compare a
measurement of 3 cubes to
a measurement of “part way
up on the popsicle stick.”

Remember, we discussed this weather
report at the beginning of the lesson.

Do you have any new ideas
about how to compare the
islands’ weather after
watching and thinking
about the video?

Weather and Climate @Home Lesson 2

If we want to be able to compare the temperature and precipitation data
for these three islands, we need to gather data that is measured in the
same way for each island.

Do you think meteorologists use tools like
popsicle sticks and cups to measure rainfall?

How do you think meteorologists
measure rainfall?

Meteorologists compare
weather data from different
places, so they need to
agree on a way to measure
precipitation and
temperature.

For precipitation, they often
measure in millimeters.

Weather and Climate @Home Lesson 2

The precipitation data
for one of the islands—
Creek Island—is measured
in millimeters.

We will learn more about
how to measure
precipitation in millimeters
in a later lesson.
