The educational resource shows an interactive animation about the heating curve: when a body is heated, its temperature increases until there is a change of state; while the change takes place, the te ...
The educational resource shows a Flash animation about the greenhouse effect The Earth is an open material system, because it interchanges matter and energy with outer space.
The educational resource shows an interactive animation about the first law of thermodynamics:when we heat a pressure cooker, the heat we supply to the water is used to increase the temperature of the ...
This learning object aims to differentiate between the concepts of weather and climate. It reaches the conclusion that there are major differences between seasons, countries, places, etc.
The educational resource shows an interactive animation about the heat: heat is the transference of energy from one body to another in such a way that the internal energies of both are modified. If th ...
The educational resource shows an interactive animation about the mechanical equivalent of heat: if energy is measured in Joules and heat is a form of energy, what is the relation between Joules and c ...
The educational resource shows an interactive animation about the second law of thermodynamics for heat engines: it is not possible to achieve perpetual motion based on continuous reciprocal conversio ...
This unit is based on a brief review of what has been learnt about the topic (the learners should now know a lot), using slides/photos showing different types of weather and seeing if the learners can ...
This learning object aims to differentiate between the concepts of weather and climate. It reaches the conclusion that there are major differences between seasons, countries, places, etc.
The educational resource shows an interactive animation about the latent heat concept: the energy needed to produce a change of phase per unit mass is known as latent heat. This energy does not contr ...
