Dissemination on the importance of pH for the oceans’ life and other environmental impacts

During the European Night of researchers, research centres, universities and scientific associations from all over Europe organize different activities for all the public. In the case of Gran Canaria, the event was organized by the The Canarian Science and Technology Park Foundation of the University of Las Palmas de Gran Canaria, giving as a result the Macaronight, an event that took place in the Plaza de Santa Ana in Las Palmas de Gran Canaria.

From the Group of Environmental Management, Technologies and Biogeochemistry we left the laboratory to present our work on the streets through two fun and educational activities.

In particular, we chose two themes: the environmental impact of recreational and/or tourist activities on sensitive natural areas, and the importance of pH in life and marine environment, demonstrating how this famous scale of acidity can be represented through simple experimentation and just with “home ingredients”.

Schoolchildren (and also adults!) checked the pH of different solutions of everyday items such as toothpaste, jet water, soft drinks or detergent using lombard cabbage extract as a colorimetric indicator. This experience was used to explain the environmental problem associated with marine acidification, on which a “research kit” was distributed to develop at home or in the classroom. This experiment involves tracking the dissolution of shells from marine organisms in white vinegar (which would simulate a highly acidified ocean).

On the other hand, and taking advantage of the ECOTOUR Project, fom the MAC 2014-2020 Territorial Cooperation Call that we have active, we emphasized the environmental values that La Marciega hosts. This natural place, located in La Aldea (Gran Canaria), represents a refuge for the birdlife of the island through which the protagonist of our story, with the help of many schoolchildren during the morning, walked “without leaving trace in the environment”.

Thus, through a panel that highlighted the precautions to take into account when going through a natural environment, a series of “environmental challenges” similar to those in the famous table games were passed. Walking without leaving the trail, respecting the flora and fauna and avoiding making a fuss are some of the recommendations that were remembered and encouraged among schoolchildren to generate as little environmental impact as possible in our spare time outdoors.

Meet us at Macaronight next Friday 27

The Macaronight (@MacaronightEU) is the shared way of the Macaronesian archipelagos to participate in the European Resarchers’ night, an initiative held on the last Friday of September each year. The aim of this event is to show the work that involves being a scientist, bringing it closer to society, promoting scientific culture in general, and demonstrating to the future generations the possibilities when choosing a career in science.

In Gran Canaria, Friday the 27th is presented as a day of activities for all ages. From the Research Group on Technologies, Management and Environmental Biogeochemistry (TGBA) we will be participating with experiments of fun chemistry and a special outdoors board game in which the objective will be to walk around the environment… without leaving trace!

If you come from a secondary or primary school, or as a family, we encourage you to stop by our tent, in the morning or afternoon hours, in the Plaza de Santa Ana.

If you are interested in participating directly, collaborating on the dynamics that we develop during the day with visitors, and also certify your hours through the ULPGC Technology Science Park Foundation, then do not think about it anymore and fill out the form below.

A happy holidays postcard from La Marciega

Summer holidays are approaching, and with them, beach days and spare time to explore new places. There is no need to go far at all to discover new corners that are worth a walk and a souvenir photo. What’s more, there’s no need to leave Gran Canaria. We are seeing this with the ECOTOUR Project in La Aldea de San Nicolás, visiting and getting to know the area a little more and more.

Proyecto ECOTOUR en La Aldea
El Charco, La Aldea – July 2019

This place has been selected as one of the case studies of the Project for its unique natural attractions, both coastal and concurrent with the environment of the channel and mouth of the Barranco de La Aldea, one of the largest of the whole island. It is an area of great landscape beauty and high natural and cultural value, of interest for the development of new touristic activities with special emphasis on the promotion of eco-tourism. Activities of interest are linked to enjoyment and respect for nature, landscapes, bird watching and hiking among others, in an environment that is still outside the area of influence of mass tourism. The coastal strip of the entire municipality is characteristically rugged and rocky, and its beaches, in this steep coastal framework, correspond to the mouths of the network of deep and narrow ravines. In the area, it is interesting to allude especially to the area of El Charco, in the main ravine bed, a place of an enormous natural and cultural value.

Inviting you to discover this place, taking care of its natural and cultural singularities, we wish you a happy summer holiday with this postcard:
