Hi, my name is Keya.

One hot, sunny day, I went to the community pool.

My dad and little brother, Samar, were there, too.

I was getting out of the pool when I heard music coming from far away...

The ice cream truck was coming!

“Ice cream!” Samar shouted. “Let’s go!”

He headed for the parking lot where the ice cream truck always stopped.

Dad laughed. "I'd better catch him! Meet us at the ice cream truck."

He ran after my little brother.

I started to follow them.

That’s when I found out that I had a big problem.

I’d have to cross the parking lot to get to the ice cream truck…

And I wasn’t wearing any shoes!

That morning, when we got to the pool, the sky was cloudy.

The parking lot and sidewalk were cool.

So I left my shoes in the car.

Full Screen

But the sun had come out.

It had been shining on the parking lot for hours.

I needed my shoes!

Why do you think Keya wanted her shoes?
Have you ever walked barefoot across a parking lot on a hot day?

Full Screen

I thought about what it would feel like to walk barefoot by the pool.

The wet sidewalk would be cool.

Full Screen

Parts of the sidewalk in the shade would be cool, too.

Full Screen

But where the sun was shining on the sidewalk, it could get very hot!

Full Screen

And where the sun was shining on the parking lot, it would get very hot, too!

Full Screen

Walking barefoot on a hot parking lot would hurt!

I would have to walk like this: Ow ow ow ow ow.

Full Screen

I wanted to get to the ice cream truck.

But I didn’t want to walk where it was hot.

I looked around, and here’s what I saw…

Full Screen

There was shade under each umbrella.

I knew the shade would be cool.

Full Screen

The snack bar made a shadow.

That would be cool, too.

Full Screen

People getting out of the pool have splashed cold water onto the cement.

Those puddles would be cool.

The green grass was wet.

It would be cool under my feet.

Get a copy of the map showing Keya at the pool.

Remember: She wants to walk, not swim!

I thought about it.

Here’s what I decided to do.

Full Screen

I jumped from one patch of shade to the next.

Full Screen

Then I splashed through the puddles and jumped into the snack bar’s shadow.

“I see why you took the long way to get here,” he said.

“You earned a treat. What would you like?”

Dad bought me my favorite ice cream bar.

Then he said, “Watch your brother for a minute. I’ll be right back.”

Dad went to the car and got my shoes.

“Thanks, Dad!” I said.

I put on my shoes.

I walked back to the pool.

I sat in the cool shade under an umbrella and ate my ice cream.

It was great.

Discuss: Think about how Keya looked for shady spots where she could walk
barefoot. Look at these cows. What do you notice? Can you explain what the
cows are doing?

Here’s what we noticed. The tree blocks the sun and makes a shadow. The cows
are all standing in that shadow. Just like people, cows like shade on a hot day.
It’s cooler in the shade!

We don’t have time to grow trees in the pasture. But looking at trees
can help us figure out why they are good at making shade. Take a look
at these trees and their shadows. Discuss:

Step
02/11
The skinny tree makes a skinny shadow. Farmer Josie’s cows need a
wide shadow so more than one cow can be in the shade. So Farmer
Josie needs a wide Shade Maker.

Step
03/11
Take a look at these two trees. Cows need to be able to get into the
shade that’s under the tree. Discuss:
Full Screen
Controls Icon Exit Full Screen
Step
04/11
Both trees make big patches of shade. But tree #1 is so short! It
would be much easier for cows to gather under tree #2. We think a
Shade Maker should be tall.

Step
05/11
Take a look at these two umbrellas. Discuss:
Full Screen

Step
06/11
A tiny umbrella makes a tiny shadow, too small for a cow! To help a
couple of cows stay cool, you need a big wide Shade Maker, more like
the big umbrella.

Farmer Josie had an old blanket. She used a couple of poles to make
the blanket into a tent, like this. Discuss:
Full Screen
Controls Icon Exit Full Screen
Step
08/11
We thought that tent was too small for the cows. So Farmer Josie
made some changes. She used taller poles and made a tent that
looked like this. Discuss:
Full Screen

Step
09/11
Farmer Josie’s new tent seemed too skinny to us for the cows! We
thought there might be a way to do better. Discuss:
Full Screen

Step
10/11
We thought she could use the blankets to make a roof and use the
poles to hold it up. But that’s just our idea. There are often many
good ways to solve a problem.
Full Screen

Step
11/11
Maybe you have other ideas you’d like Josie to try. If there’s time,
draw a picture of your idea. Then spend some time trying to figure
out how to make it even better.

Activity: Where Is It Hot? Where Is It Not?

Now that you know where it's too hot to walk barefoot, you can also figure out when to sit if you want to cool off on a hot day.

  • Take a look at the photo on the next page and think about clues that tell you where it’s hot and where it’s cool.
  • Discuss: Where would you go if you wanted to stay cool? Where would you go if you wanted to warm up? What clue are you using to make your choice?

Here's what we think

We know that sunshine warms things up.

So if we want to cool off, we look for a shady spot. If we want to warm up, we find a place in the sun.

Next time you're outside on a sunny day, compare the temperature in the sun with the temperature in the shade. Do you feel a difference?

THIS LESSON WAS REVISED ON JULY 1, 2021. Here is a link to the previous version.
In this Read-Along lesson, students listen to an illustrated digital storybook with student participation. If you would prefer to read the book aloud yourself, you can switch to the non-narrated version. In the story, Keya needs to find a way to get from the swimming pool to the ice cream truck without burning her bare feet on the hot pavement. In the activity, Cool Cows, students notice that cows (like people) use shade to stay cool. Then, they think through how they would design a shade structure for cows.
