As you read, look for the actions people took to solve a terrible problem inside a Thai cave. What do their actions show about them?

Deep inside the pitch-dark cave, 12 young soccer players stood with their coach. The boys had spent a thrilling afternoon exploring a giant cave called Tham Luang Nang Non. It was a few miles outside their hometown in northern Thailand, a country in Southeast Asia.

Now they were hiking back out. But they needed to hurry. It was June 23, 2018. One of the players, a boy named Night, was having his 17th birthday party soon. There was just one problem. Choppy water swirled ahead of them, blocking their way out of the cave.

The boys were confused. When they had come through the passageway earlier, it had been dry.

Then they realized the awful truth: The cave had flooded, and they were trapped inside.

Good Friends

Good Friends

Earlier that day, the boys on the Wild Boars soccer team had been joking around after practice. None could have imagined the day would end in disaster. Though they were of different ages and went to different schools, the Wild Boars were all good friends. And they were close with their assistant coach, Ekkapol Chantawong, nicknamed “Coach Ek.” Coach Ek often organized outdoor trips for them, like this one to the Tham Luang cave.

The boys scarfed down some snacks and hopped on their bikes. Soon, they were winding through farmland and into the mountains. At the mouth of the cave, they set down their bikes and swapped their cleats for flip-flops.

They walked past a faded sign warning visitors not to enter during the rainy season, because the cave floods. The boys were sure they were safe though. The heavy rains were still weeks away.

But a changing climate has been making the seasons less predictable. And in the days leading up to June 23, the area around the cave had seen more rain than usual.

safe though. The heavy rains were still weeks away.

But a changing climate has been making the seasons change also. In the days before June 23, the area around the cave had gotten more rain than usual.

Swirling Water

Swirling Water

The boys stepped through the cave’s entrance and into a big, airy room. They breathed in the smell of wet, mossy limestone. Thick stalactites hung down like dragon teeth. As they walked, the cave grew narrower and narrower. Light from the outside world faded away.

But the boys weren’t scared. About one mile in, they came to a junction where the tunnel forked in two. The Wild Boars knew they should turn back if they were going to make it to Night’s party. But now, deep in the cave, they felt a tug that cavers know well: What if we go just a little farther?

They kicked off their flip-flops, dropped their backpacks, and continued. They wriggled through tight spaces. They stomped up and down rough slopes. Their bare toes gripped slippery rocks.

Three hours later, the boys decided to head back. But when they returned to the junction, there was only swirling water.

Coach Ek calmly told the boys the water would surely go down. He said they should find a place to sleep for the night. They found a section of fairly dry, sandy ground. Night thought about his party, about the delicious food his mother had been cooking all afternoon. His teammates were thinking about food too. They hadn’t brought any with them.

At least they had the most important thing: water.

The water dripping from the cave walls had been filtered through the rocks, cleaning it. The boys cupped their hands to catch the drops as they fell. Then one by one, they drifted off to sleep. They dreamed of tomorrow, when they’d be able to get out.

In the Thai language, Tham Luang Nang Non means “The Cave of the Sleeping Lady.” The cave is named after a princess from a very old story.

Dangerous Diving

Dangerous Diving

As the boys sank into sleep, their worried families realized what had happened. Sangwut Khammongkhon, the director of a local rescue organization, heard about the situation around 9:45 p.m. In the lashing rain, he and his team rushed to Tham Luang. When they got to the junction, they saw the swirling water—and the pile of backpacks and flip-flops nearby. Sangwut realized the boys must be trapped somewhere on the other side.

The heavy clouds over Sangwut’s heart matched those in the sky. He knew the cave very well. And he knew that when water reached the junction that time of year, it wouldn’t go down until the rainy season ended in October.

What happened next was a flurry of activity. An expert British caver was called in. He lived in Thailand and had created detailed maps of the cave. A team of Thai Navy SEALs also arrived. The SEALs are an elite military unit made up of highly trained divers.

But diving in a cave is a lot different from diving in the open sea—and a lot more dangerous. The SEALs did not have the equipment or experience to dive through flooded cave passageways.

On June 26, three days since the boys had become trapped, the rescue workers were becoming discouraged. The water was cold. The current was strong. The water was so murky that it was like trying to dive through coffee. The expert caver said there were only a handful of people in the world who could dive in water like that. Those people had to be brought to Tham Luang immediately or the boys would surely die.

What no one wanted to say was that they didn’t even know if the boys were still alive.

There was something no one wanted to say: They didn’t even know if the boys were still alive.

To help divers reach the boys, rescuers pumped water out of the cave—even as heavy rains continued to send more water pouring in.

“Keep Fighting”

“Keep Fighting”

By this point, the Wild Boars were in rough shape. Hunger clawed at their stomachs. They took turns crying and comforting each other.

It didn’t help that the cave was damp and chilly. The boys scooped out a ditch in the sand where they could huddle and keep warm.

Coach Ek kept reminding the boys how strong they were. “Keep fighting,” he told them. “People are looking for us.” And he was right.

Over the following days, all of Thailand—and the world—was drawn into the dramatic scene at Tham Luang.

Soon, more than 1,000 volunteers had gathered at the cave entrance, now known as base camp. There were scientists, members of the Thai and U.S. militaries, government leaders, engineers, and doctors. The world’s best cave divers arrived to offer help and guidance.

On July 2, two of the expert divers put on their gear and disappeared into the water. Eventually, they found a space with an air pocket. One of the divers rose to the surface and took off his mask—only to be overwhelmed by an awful smell. But it was a stench that filled him with relief: human waste. That meant the boys must be close by.

Moments later, the divers emerged from the water. Just above them crouched all 12 boys and Coach Ek.

Alive.

Tragedy Strikes

Tragedy Strikes

News that the Wild Boars had been found swept around the world. But as one of the divers pointed out, being alive inside a cave and being alive outside a cave are two very different things.

The boys desperately needed food and supplies. It wouldn’t be easy. Cave divers use special equipment to breathe underwater. They would have to squeeze through narrow passageways that could damage it. One wrong move could be deadly.

Despite the danger, six SEALs and a Thai army doctor managed to reach the boys with food, medicine, and blankets. Over the next few days, the SEALs made more dives with food and letters from the boys’ families. Many of the letters were for Coach Ek, telling him he shouldn’t blame himself.

Then tragedy struck.

Late on the night of July 5, one of the SEALs drowned while on a supply dive. His death sent a wave of sadness through base camp. 

But the other SEALs reminded themselves that they still had a mission to finish. They needed to get the boys out.

The Rescue

The Rescue

On July 8, the rescue team headed into Tham Luang. They had decided divers would carry the boys out through the water. But the plan was risky—and it was very possible that not everyone would survive.

Fourteen-year-old Note would be the first boy brought out. He was given medication that made him fall asleep. (This was to prevent him from panicking.) He was fitted with a breathing mask attached to an air tank.

Then a volunteer diver pulled Note underwater. With one hand, the diver gripped a guideline—a rope that had been set up to help him find his way through the murky water. With the other hand, he cradled Note close to his body. The route out of the cave was complex, a mixture of flooded passageways and dry or partly flooded chambers.

Finally, after more than five agonizing hours, Note and the diver reached the last chamber. There, 100 rescuers were waiting. Note was placed on a stretcher. The rescuers passed him from hand to hand over the steep and slippery final section of the cave.

At last, they got him to the mouth of the cave. When the news spread that the first boy had been safely brought out, after 16 days of being trapped in the dark, cheers erupted around the world.

Over the next two days, every remaining boy and Coach Ek were all brought to safety.

After their rescue, the boys were full of gratitude to everyone who helped get them out. Here, they hold a portrait of the Navy SEAL who died during the rescue.

Forever Changed

Forever Changed

Today, the boys’ lives are both back to normal and forever changed. They are world famous. Strangers stop them on the street to take photos with them. They have changed on the inside too. Their parents say they are more patient and thankful for small things. And now some imagine becoming Navy SEALs, like the brave men who risked their lives to save them.

“We feel like we have a lot of parents around the world,” said one of the boys, 14-year-old Adul. “I wish I could meet you and thank you from the bottom of my heart.”

1. Preparing to Read

Spark Engagement, Watch a Video, Preview Vocabulary

  • Ask students: If you had the opportunity to explore a cave, would you like to go? Why or why not? Pair students up to discuss what they think they might see inside a cave. 
  • Show or assign the video “Behind the Scenes: Trapped in a Cave” to engage students in the topic and to preview the article. Have students complete the Video Discussion Questions in pairs or small groups.

  • Show or assign the Vocabulary Slideshow to preview challenging words. Then assign the Vocabulary Skill Builder before or after reading. Highlighted words: climate, stalactites, junction, cavers, lashing, elite, current, murky, emerged, chambers

  • Call on a student to read aloud the Up Close box on page 4.

2. Reading and Discussing

  • Ask students to read the article independently. They can also listen to our special Immersive Read-Aloud with author Christina Soontornvat. (Look at the Digital Spotlight on page 5 of this lesson plan for more information and ideas on how to use the Immersive Read-Aloud!)
  • Put students into small groups or pairs. Ask them to read the story a second time and  discuss and write their answers to the close-reading and critical-thinking questions. Discuss the SEL Focus together as a class after reading.

SEL Focus

Understanding and Expressing Gratitude

Together, read Adul’s quote at the end of the story and the caption of the photo on page 9. Remind students what gratitude is (the feeling of being thankful). Ask: Why does Adul say that he and the rest of the team feel like they “have a lot of parents around the world” that they’d like to say thank you to? (He says this because hundreds of people from all over the world worked to rescue him and his teammates from the flooded cave. People around the globe followed their story on TV and rejoiced when the boys were brought to safety.) Ask your students to think of a time when they felt gratitude. Who or what were they thankful for? How did they show their gratitude? Make sure to let your students know that feeling grateful can help people feel happier and build strong relationships with others.

Close-Reading Questions

 

  • Reread the opening section on page 5. Where and when does the story take place? Who is the story mainly about? (key details) The story takes place in the summer of 2018 in a giant cave in northern Thailand, a country in Southeast Asia. The story is about 12 young soccer players and their coach, who were trapped inside the cave after it flooded.
  • Reread the section “Good Friends.” Why does the author say that “none could have imagined the day would end in disaster”? Use details from the section in your answer. (text evidence) The boys had had fun at soccer practice and were used to taking outdoor trips together. They didn’t think they were in danger when they entered the cave because the start of the rainy season was still weeks away. The boys didn’t know that the area around the cave had seen more rain than usual in the days leading up to their trip.
  • According to the section “Swirling Water,” what did Coach Ek do once the boys realized the cave had flooded? What do his actions tell you about Coach Ek? (character traits) Coach Ek calmly told the boys that the water would surely go down and that they should look for a dry place to sleep for the night. His actions tell us that Coach Ek was trying to make sure the boys would not get worried and start to panic. He was also trying to keep the boys safe by making sure they would find a dry place and get rest.

  • Reread the section “Dangerous Diving.” Why were the rescue workers becoming discouraged? (text evidence) The rescue workers were becoming discouraged because they knew that the water level in the flooded cave wouldn’t go down until October. They also knew how dangerous it was to dive inside the flooded cave, where the water was cold and murky, and the current was strong. Worst of all, the rescuers didn’t know if the boys were still alive.

  • Compare the section “Dangerous Diving” with “‘Keep Fighting.’” How did the rescue team’s mood, or feeling, change? Why? (compare and contrast) At first, the rescue workers were discouraged. They knew that the flooded cave was a very dangerous place, and they didn’t know if the boys were alive. Later, more and more people joined the rescue effort, including the world’s best cave divers. After the boys were found, the rescue team felt immense relief. 

  • Reread the sections “Tragedy Strikes” and “The Rescue.”  What did the rescue workers do after the boys and their coach were found? What adjectives would you use to describe the rescue workers? (text evidence/character traits) The rescue workers risked their lives to bring food, medicine, and blankets to the kids inside the cave. They also delivered letters from the boys’ families. Finally, on July 8, the rescue team started bringing the boys out one by one through the flooded passageways. Some adjectives to describe the rescue workers are: brave, selfless, kind, fearless, heroic.

  • According to the section “Forever Changed,” how do you think the experience affected the boys? (inference) The experience was likely scary for the boys. Yet it taught them to appreciate the little things in life, probably because they are happy they survived their ordeal. It also taught them the world can come together to help people in need.

 

 

Critical-Thinking Questions

  •  The rescue workers who brought the Wild Boars to safety are often called heroes. Why do you think that is? Use evidence from the text in your answer. (text evidence) The rescue workers bravely risked their lives to save the members of the Wild Boars team. They worked endlessly for more than two weeks to bring them out of the cave. One of the rescue workers even died in the effort. This is why the rescue workers are often called heroes.
  • Consider Adul’s quote in the last paragraph. In your own words, explain what it means. (interpreting text) Adul feels grateful for all the people from around the world who came to rescue him and his friends. These people worried about his life as his own parents did.

3. Skill Building and Writing

  • Distribute the Text Evidence Skill Builder or assign the Slide Deck. These are available on two levels.
  • As a class, read the writing prompt in the Write to Win box on page 9. Have students use their completed Text Evidence Skill Builder to help them respond to the prompt. Then you can send their essays to our writing contest.

4. Digital Spotlight

Make sure you and your students listen to the Immersive Read-Aloud for this story. This extra-special read-aloud uses music and sound effects to bring the story to life. Encourage your students to close their eyes while listening so they can picture what’s happening in the story. The immersive read-aloud is also great for family engagement. Send home a link to the read-aloud and encourage families to listen to the story together. For more ideas on ways to engage families, take a look at our Family Engagement Letter.

Differentiate and Customize
For Striving Readers

Before reading the story, share this cross-section of the cave with students. It clearly shows how certain passageways were flooded, while others (like the area where the boys were found) were not. It will help students better visualize what happened inside the cave as they read the story.

For Advanced Readers

Have students work in groups to do research to find primary documents about the cave rescue; in other words, articles or videos that were created at the time of the event. Have them report back to the class about what they learned from the primary sources that they didn’t find out in the article.

For Multilingual Learners

Ask students to highlight any words they don’t know while reading the story. Then pair each multilingual learner with a student whose first language is English. Have them work together to create a slideshow with each new word, in the same style as our Vocabulary Slideshow (with an image, definition, part of speech, and audio pronunciation).
