Observations Comments 2 hours Discussion in the classroom about the term geothermal and reflection on how this phenomenon occurs and where it can be derived. 5 hours The subject study was conducted through online information and other external sources, but also through the experiment, where children observe how the phenomenon of geothermal energy works 1) To understand and appreciate that any action requires a higher energy consumption. To raise awareness, through the history of man on the planet, on the use of energy sources in every season. 2) To understand that excessive use of non-renewable energy sources has led to energy crisis and a huge burden on the environment by creating a series of serious problems, which if not solved, would have the effect of preventing the life on the planet. 3) To raise awareness that there are available renewable and clean energy sources to be used, to meet the means and ways in which these can be used, so to contribute to the solution of the energy problem in the future and reverse the poor state of the environment. 4)To form positive attitudes and

behaviors towards the wise use and saving of energy in an individual, national and international level. To be aware of new technologies based on the use of clean energy sources. 5) To acquire, eventually, the necessary knowledge that will enable them to form an opinion about what it "energy" and "life" mean, in order for them to want to contribute to the design of a future where life will not be poisoned by thoughtless use of energy. 1) What is energy? Each physical system comprising (or alternatively saves) a quantity called energy. Energy, therefore, is the capacity of a body or system to do work. Any form of action from children's games to the operation of the machines and the food cooking until the production line at the plant requires energy consumption. The really various forms of energy are behind the unimaginable variety of natural phenomena. 2) Energy Forms. Mechanical energy, combining kinetics and dynamics. Electromagnetic energy, combining electric and luminous or radiant energy, Nuclear energy Thermal energy Chemical energy Mass-energy 3) Renewable and non-energy sources. Renewable sources Solar energy


Aeolic energy Biomass Geothermal energy Non-renewable Coal Oil Natural gas 4) Geothermal. geothermal Geothermal energy is the natural thermal energy of the Earth leaking from the hot interior of the planet towards the surface. The following areas were surveyed since 1971: Milos, Nisyros, Lesvos, Methana, Sousaki, Kamena Vourla, Thermopylae, Ypati, Edipsos, Kimolos, Polyaigos, Santorini, Kos, South Thessaly Almopia, Strymonas river, Xanthi, Samothraki and others which showed intense geothermal activity.

An experiment was conducted with the main aim for the children to understand what geothermal energy is and how important this energy source is for humans and the environment. Students will reflect and formulate conclusions on renewable energy sources and energy saving.


A. Approaching the problem During a debate in class on renewable energy sources, the term geothermal was mentioned, a term that many of the children did not know until then. So the children wondered what is geothermal energy and how it is collected from the Earth.

B. Case Study.

Activity Experiment

Experiment observation

Watch videos on the internet

ACTIVITIES Material Pot, water (boiled), foil, toy windmill, cooker

Comment Take a saucepan and add water. Place the pot on the stove and bring to a boil. Then close the pot with foil so that the vapors cannot leave the pot. Once the water starts to boil open a small hole in the foil and put the toy windmill over the hole. The children noticed that the steam from the boiling water turned the toy windmill. https://www.youtube.com/watch?v=lrHsfpH_UD4 The students watched a video on how we exploit geothermal energy for the production of "clean" energy.


Worksheet 1

A. Watch the map of Greece and outline on it the points where geothermal springs were discovered according to what you have learned so far (you may refer to the map of your classroom).
