Four themed tours to the Hontomin CO2 Storage Plant were developed.
These included a set of activities in Hontomin village.
The tours have been designed for groups of 20 children, and last approx.
4hrs - including the bus trip to Hontomin.

The Hontomin CO2 Mystery Tour…
Clue 1: The molecule, which has to be kept deep
underground, is hidden in the rock near the church.
• The children will find a container with small foam balls,
and some sticks to connect them; they have to create a
CO2 molecule and draw the element symbol based on a
drawing. They keep the molecule they have made until
the end of the Mystery Tour. If the molecule is well
constructed, they will obtain the next clue.
Clue 2: Search the yellow house where scientists monitor if
the Earth is moving, if you create a good tremor, the scientist
will give you a better clue!
• The yellow house is the office of CIUDEN in Hontomín,
where a seismograph is located; jumps will create a
vibration that has to be higher than a certain magnitude,
then the “scientist” will give the children a new clue to
continue with the tour…

Clue 3: You will find the magic rocks that are used to store CO2.
• The children have to collect both reservoir and seal/ cap rock
samples in a certain part of the village - if they succeed, they
obtain their next clue.
By now each child should have a CO2 molecule, a reservoir rock and
a seal/ cap rock, if they want to continue with the game…
Clue 4: If you have “all the ingredients”, look for the scientist with a
white lab-coat, who is sleeping on a bench in the village.
• The monitor has to wait sleeping on a bench with a poster, which
says… “You have to guess the magic word or I won´t wake up”.
Once the Mystery Tour is finished, the children will be guided to the
CO2 Storage Plant with all the stuff they have collected. There they
will make a model of a CO2 store, explaining why we need a
reservoir rock, a seal/ cap rock, and where the CO2 molecule will be
stored. Finally, they are given a short explanation of the journey of
the CO2 is given.

Materials required: Lab coat, wig, paper, rock cores, small foam balls and cocktail sticks to
make molecules, laminate paper for the clues.
To make the CO2 storage models, use the activity explained in the “CO2, Do I Know You?” file.

7. Wine & CO2, Wine & Geology

An entertaining introduction to CO2 for adults...
Carbon Dioxide (CO2)
and wine making…

9. Wine and CO2
An entertaining introduction to CO2 for adults...
• The first wine tasting event was called “Geology & Wine”.
• It focussed on the analysis of different certificates of origin from
the Castilla y Leon wine making region, highlighting the impacts
of weather and soil characteristics, as well as the different types
of grapes.
• During the explanation, participants all got a taste of each variety
being discussed.

10. Wine and CO2
An entertaining introduction to CO2 for adults...
• The second event - “Wine & CO2”, focussed on the role of gases like
carbon dioxide and oxygen in the process of wine creation.
• Described the different processes involved for different wines including
carbonic maceration or sparkling wine.
• The session closed with an introduction to professional wine tasting.
