In winter, three friends decide to go to the mountain for their holiday camp.

Camping at the mountain

“I think I left it next to the river, we have to go and get it, Sam, it’s my birthday present!” she says, crying. “Don’t worry, we are not that far from the river, I’m sure it is still there!” They turn around and walk back to the river. Very soon, they arrive, and the little boat is here, waiting for them at the river's edge. “Here you are, little rascal! says Léa, very happy to find her toy. Oh! Your, name will be Little Rascal now!” “Perfect! Now we can go back to the camp, says Sam. Be sure you don’t forget anything!”

<a href="bookcreator://page/p-A1VUBhRQ2WJ6PL9q3DsA" style="color: rgb(0, 0, 0);">Continue the walk to paragraph 42.</a>

“It floats! It’s moving on the river like a real boat!” shouts Léa. The three friends are very happy, they celebrate this moment. Sam catches Léa’s boat before it goes too far. “Well done Léa, but be careful, you almost lost your boat! says Sam. And if you don’t have your boat, how will you beat me in the race?”

<a href="bookcreator://page/X1a-k0BJT_mgUqbPbhs_fQ" style="color: rgb(0, 0, 0);">To start the race, go to paragraph 26.</a>

Help Sam find the response to Léa’s question. True or false ? All matter comes from space and the universe, including the particles that make up our body and all living and non-living things on Earth

IT'S TRUE!

Well done if you found it; it was a hard one! If you did not find the right answer, no worries, you will learn all those things. It's a matter of time! “Well, I did not know that!” exclaims Sam. Mélanie, Léa, and Adam laugh. “I told you: you would have taught me something before the end of the day!” says Sam. A new shooting star appears. “Oh! Make a wish!” he says. “I wish our next adventure will be as awesome as this one!” Adam whispers to his friends. The children smile, delighted with their day, and eager to start the next one.

"I'm here to teach you lots of things, but I'm sure you'll have me discovering new things on our first walk!" says Sam with a smile. Where do you want to go? In the forest or by the river? Will we do both anyways!"

“We won! shout the kids, we won!” “Congratulations guys! says Sam, your boat is very fast! Since you won, I will share my marshmallows with you tonight in front of the fire!” “Yeahhh!” The three friends celebrate again and almost fall in the river! “Let's go somewhere else before you get all wet!” says Sam, laughing.

“Oh, I see now,” says Adam. I'd better think of another souvenir idea to bring home.” While Mélanie and Adam were talking, Léa went outside to make snowballs, very determined to have a snowball fight. “Mélanie, Adam, come and see outside!” she shouts. As soon as their heads were out the door, Mélanie and Adam were hit with a huge snowball. Of course, they do not wait long to do the same!

Mélanie loves reading and learning new things. Her friends immediately thought of a book when her 13th birthday approached. They chose a nice book about the universe and the stars that they offered her with the help of her parents. Mélanie knows that she will have better luck observing the stars in the mountains, where there will be less light than in the city.

“I see! but is it the same for all matters?” Léa asks. “Yes! But not for the boiling point and the freezing point, they are specific to each matter, Mélanie says. For example, water boils at 100°C and freezes at 0°C, and blood…well…” “And blood freezes at -2°C and has a temperature of 37.5°C in your body, so you’re not about to freeze Léa, don’t worry!” says Sam the coordinator, taking them by surprise. “You know everything Sam!” Adam says.

Help Adam understand the different states of matter. It is generally said that there are three states of matter: SOLID, LIQUID, GASEOUS. Can you select the right state of matter for each element?

“You get it now? Sam asks. This drop and the lake do not behave the same because particles of which solid, liquid, and gaseous matters are made of do not behave the same!” The three friends shared the magnifying glass to observe the drops of water that fell to the ground.

Mélanie, Adam and Léa are inseparable. The three best friends have never left each other since childhood. They have always lived in the same town, on the same street. These three have completely different interests: birds and insects for Adam, space for Mélanie, manual activities for Léa. However, when it comes to going on an adventure, it's always together, whatever the destination!

Léa Adam Mélanie and Sam walk deeper into the forest. The four adventurers try not to make too much noise, as they are walking on a thin layer of snow. The children hear lots of new sounds that they have never heard before! “How lovely are these lines of light going through the trees, says Mélanie. Sam, do you think we'll be able to see the stars?” “It's too early! But we'll try to see them during the week, I promise,” Sam replies. “Let's see these white trees next to the frozen lake, they look giant!” says Adam.

<a href="bookcreator://page/Wjfo2jPPQzCwbHX3OE4lcQ" style="color: rgb(0, 0, 0);">Continue the walk and go to paragraph 29.</a>

When water is heated and starts to make bubbles, it’s boiling. When snow is heated and starts to turn liquid, it’s melting. When water vapour cools down and lands on Adam’s magnifying glass, it’s condensing. When water cools down and becomes ice, it’s freezing.

Sam, Mélanie, and Adam join Léa next to the river. “This is the first time I try to put it on moving water, I hope it will float correctly!” says Léa. “Oh really? Let’s see! If it works, why not have a race?” Sam proposes. The three children smile broadly, confident that they will win the challenge. Léa puts her boat just after the small waterfall and…

After a long train journey, the three friends finally see the base of the mountain. When they arrive at the camp, they settle into the chalet and unpack their things. Léa exclaims, “There's water everywhere! How is it possible?” She follows the water trails on the floor and gets to their coat, specifically Adam's coat. “Adam... what did you put in your pockets to get it all wet?” Léa asks. “A snowball! I wanted to have a snowball fight with it and take it home as a souvenir...” replies Adam. “But Adam, your ball will melt, it won't stay like that, it's water,” says Mélanie. “What do you mean?” Adam asks.

Sam walks to the exit of the cave and fills his cup with snow, then puts it on his device and lights it with a lighter. “I'll make a hot chocolate with melted snow and your chocolate squares,” he explains. Soon, the snow becomes water and starts to make bubbles. Sam adds the chocolate in the cup. Adam approaches his magnifying glass from the water cup, and the glass of his magnifying glass fogs up. “What’s is that? Adam asks. I can’t see anything!”

“Wow! Have you seen the little waterfall over there?” Léa asks. “And have you seen the length of this river? It must go very far from here!” replies Adam. “The water goes down to the frozen lake near the forest, and it comes from the top of the mountain when the snow is melting!” says Sam. “Can we go closer?” asks Léa, eager to use her tiny boat on the river. “Of course, the river’s stream is not too dangerous at this time of the year, but do not slip, you would get cold!”

Adam is delighted. Even though he hasn't seen a bear, he discovers many things in this new landscape. Taking a closer look at these trees, he realises that they are not white, but covered with snow. Suddenly, a drop of cold water falls on his nose. “It's the snow that's melting,” he exclaims, as the drop goes down his cheek. I wonder how this drop can move like that on my face but the ice on the frozen lake can’t. What if I looked at this drop with my magnifying glass?”

While the children were celebrating, Sam made a little boat out of a walnut shell and a small stick he found on the ground, a piece of fabric and some yarn he carried in his bag. “Here is my boat,” he says with a smile. The friends place their boats, wishing both of them good luck. “Are you ready?” Sam asks. All 4 start the countdown: “5…4…3…2…1…Go!!”

The cave is perfect for our 4 adventurers: not too big to be a bear cave, not too small to be cramped. Time passes and the weather does not calm down. “While waiting for better weather, we will have a snack, it will do us good after our journey,” says Sam. He takes a chocolate bar and the famous marshmallow bag out of his bag, and hands it out to the children. He also takes out a cup and a strange device.

Léa always needs to keep herself busy. She is so good with her hands that it took her less than 10 minutes to build the kit boat she received for her birthday! With the help of Mélanie and Adam, she decorated it but could not find a name for it yet. And around her home, there is no river on which she could sail her little ship

“That was a big first day in the mountains for you, right?” Sam says. The three children nod. The fatigue begins to appear. After another 15 minutes, the weather starts to improve. The four adventurers leave the cave. It is dark. Suddenly Mélanie looks up and exclaims, “The stars! Have you seen those stars?” Sam, Léa, and Adam raise their heads in response. “Wow! This is Big Bear!” says Adam. “And this is Orion!” replies Mélanie. “You see, you three got what you wanted: see a bear, see stars and find a name for the tiny boat,” says Sam smiling.

They climb the mountains for a few minutes and start to hear distant noises. “What is that? It’s a little bit scary!” says Mélanie to Sam. “You will see. Don’t worry, I’m sure you will like it.” As they got closer, the noise became louder and louder. Then, after a few minutes, they saw it. “THE RIVER!!!” they shout.

“Oh, so I have… condensation of my magnifying glass! I learnt a new word, it’s hard to pronounce,” Adam exclaims. “Exactly! The same happens on glasses or on mirrors during a shower for example.” The four adventurers finish their snack and watch the snow still falling outside. To keep the children from getting bored, Sam suggests a game: try to remember everything they have learned today.

But suddenly, the weather turns cloudy, it starts to snow very heavily, so much so that Sam can no longer see the smoke coming out of the chimneys of the chalets. He does, however, see a small cave. “Let's go and take refuge there until the weather calms down!” he shouts to the children.
