Hello there,

we are Ella and Fero. Join us on a journey of our creation and delve into fantastic microworld where we work to save our planet.

Microbes and metals teach green technology

Environmental scientists, artists and teachers from Slovakia, Poland and the Czech Republic will create and present two interactive lessons using elements of Puppet Theatre to increase the interest of children aged 10 – 12 in natural science and technology. The specific emphasis will be given on environmental sciences.


Recycling microbes

(from the field Environmental Biotechnology)

You will be invited to delve into the microscopic world, meeting microorganisms like alga Ela (full name Parachlorella kessleri) and bacteria Fero (full name Acidithiobacillus ferrooxidans). You will accompany these microorganisms during nutrient acquisition so you can understand what they can and cannot eat. Exploring their habitat, you will recognize the challenges of living in water where is difficult to find something to eat. You will observe microbial strategies for acquiring essential elements and witness how these elements attach to Ela´s surface and are stored in the algal body. Various strategies to protect organisms from toxic elements will be introduced. The lesson will also introduce Fero, residing deep in a mine surrounded by ores, and investigate its strategies for dissolving metals for „lunch“.

The lesson illustrates the importance of ecosystem components, including microorganisms and their role in environmental cleanup, forming the basis for green bio/technology. Encouraged to think creatively, children will explore how these microbial features can be harnessed to protect the environment, posing questions like whether Ela could assist in wastewater cleanup or if Fero could consume an old mobile phone. Guided by the scientist/teacher, children will seek answers, consulting Ela and Fero for advice. Ultimately, children will suggest their solutions and propose simple technologies.


Which Metal is the Best?

(from the field Environmental Engineering and Recycling)

Fero and Ela encounter challenges as they wander into Mendelejev’s house, where metals reside (represented by puppets). The metals constantly argue, each believing itself to be the most important. Proud and selfish, they struggle to communicate, some preferring a dissolved state while others favour a solid state. However, a serious situation arises—the need to build a smartphone. Fero and Ela try to help. Situation transforms for the better when metals accept common goal, start to listen to each other and work together. The lesson conveys the truth that a smartphone cannot be built without any of the metals; each is necessary and irreplaceable. Throughout the lesson, children will seek answers to questions like: Which metals are present in smartphones? Why do some prefer to be together while others do not? Which metal is the most common, valuable, easiest, heaviest, and ultimately, the most important?

The primary objective of lesson is to emphasize the significance of individual elements found in electronic devices, educating children about the names and basic physico-chemical characteristics of metals. Beyond acquiring knowledge, the lesson aims to stimulate the values of children towards environmental protection and individual responsibility in waste production. This will lead to an understanding that individuals can actively contribute to fighting climate change. Additionally, the lesson will emphasize the importance of teamwork and communication, fostering a holistic approach to addressing environmental challenges.
