Primary education (2nd cycle)

Planetarium sessions

The planetarium session consists of several parts. Initially, we make an astronomical projection6 and then we explain the sky with the simulator. We will see the planets and stars visible that night and travel back in time to observe how their positions change over the hours and days. We will also focus on the constellations, figures that ancient civilizations drew in the sky and that have reached our days. We will also travel outside the Earth to see the Sun and the planets that make up the Solar System more closely. Finally we will contemplate the secret that hides the planetarium and that makes it unique in the world!

Below you have a brief summary of the projections you can choose:


One night, when Celeste goes to sleep, she receives an unexpected visitor. It’s Moon, who knows many of the secrets of the Universe. With them we will discover that, beyond the Solar System, we can find many other planets known as exoplanets. We will see how they can be detected, what elements characterize them and other curiosities about these distant and mysterious objects.


What do we know about light? What colors make up sunlight? Zoe, a young dingo, discovers the answers to these questions from GranPa, a retired scientist who lives in a quiet country house. One day, suddenly, a mysterious gas darkens the sky. On an adventure-packed journey into space, GranPa and Zoe will have to put their scientific skills to the test to discover where this gas comes from and make the Sun’s light visible from Earth again.

3, 2, 1 LIFTOFF

Amid the mountains of junk in a landfill live a group of hamsters. Among them stands out I’Elon, a hamster who really likes science, unlike his peers who don’t take it very seriously. One fine day something mysterious from outer space falls into the landfill.

Inside the crater formed by the impact is a robot that has fallen from the spaceship it was traveling on. Putting his scientific knowledge to the test, I’Elon will have to find a way to return the robot to the spaceship before it’s too late.


The poles of the planet Earth are very cold areas and during the winter months almost no sunlight reaches them. What is the cause?

Does the same happen on other planets? On board the ship Polaris, accompanied by I’os Vladimir and the pingli James, we will discover what happens on the other planets of the Solar system and, applying the scientific method, we will try to find an explanation that answers our questions.</ p>


Vladimir the bone and James the penguin begin a new adventure aboard their spaceship, Polaris. Target: the aurora borealis. However, an unexpected impact on the ship and a landing in the middle of the jungle will raise new questions. What do they know and what are meteorites made of? Why do shooting stars shine? Back on board the Polaris and with a new companion they will start a new journey through the Solar System to try to answer these questions applying, as always, the scientific method.


Eugeni Milkman is a very peculiar character, he pilots a ship belonging to the company Galaktos that is dedicated to the distribution of dairy products (milk, yogurts and sherbets) throughout our galaxy, the Milky Way. Accompanied by Eugene and his intern, we will travel and discover what the most fascinating objects in our Galaxy look like. Crossing nebulae or riding through a black hole are very simple and fun challenges for these space travelers.



During the day the Sun warms us and illuminates our surroundings. But what is the Sun like? Are we far or near? Is it big or small? What is its color? With the devices we have in our center we will answer all these questions.

We will also be able to see if there is a sunspot or if at that moment there is a flare in the Sun.


When it is night in Montsec, the best sky in Catalonia, we can observe the Moon, planets, stars and other more distant and mysterious objects in great detail. By combining observations with the naked eye and telescopes we will get closer to discovering the night sky.



5, 4,3,2,1 action!!! In this activity we will discover details and curiosities about rockets and we will fly some of them propelled by water and air. All children will be able to enjoy the experience of taking off their first rocket.


Just as when we drive around a city we may need a map or a GPS to orient ourselves, to find the most prominent stars and constellations in the sky we can use a planisphere. We will make this device with very simple materials and learn how to use it to be able to see which stars and constellations are visible at each hour of the night every day of the year.


The Earth, the planet we live on, is just one of the objects we have in the Solar System. The Sun, planets such as Venus, Mars, Jupiter and Saturn or satellites such as the Moon hide very interesting details. With the help of images, we will have to guess, for example, which planets are rocky and which are gaseous, which planets have more satellites or also which are the hottest and which are the coldest among many other details that we can discover !


Nowadays we have a multitude of devices to know at all times what time it is, but in the past it wasn’t like that. So how did they do it? Clocks have been manufactured since ancient times which, based on the position of the Sun and seeing what its shadow looks like, have allowed us to know what time it is. In this activity we will build a sundial with simple materials and see how to use it.

Did you know that the #SerradelMontsec is a declared space Reserve Starlight?
