The educational resource shows information about the energy sources: energy sources are the resources which exist in nature from which human beings can obtain energy which they can use for their activities.

The educational resource shows a visual about the comets: Comets are small bodies, generally measuring less than 100 km in diameter. They tend to be made principally of ice. When they near the Sun, they exhibit a tail (or coma) for which they are famous.

The educational resource shows a visual about the potential electric energy of a charge at a point in the electric field: It is the work carried out by the field when the charge is brought from infinity to the aforementioned point.

The educational resource shows a visual about lunar phases: the moon is a rocky sphere about four times smaller than the earth. Its different aspects (as seen from the earth) are known as lunar phases.

El ODE contiene información acerca de qué es un cometa y muestra una animación en la que se puede estudiar el movimiento de un cometa alrededor del Sol. En la escena animada se puede modificar la excentricidad de la órbita del cometa y la rapidez de la simulación.

Explicación de como se forma una imagen usando lentes convexas.

The educational resource shows an interactive animation about the equilibrium between different states: a substance (water, for example) in different states at different temperatures (ice and water) will eventually reach an equilibrium temperature.

The educational resource shows an interactive animation about changes in water: the change from a solid to a liquid is called fusion. The change from a liquid to a gas is called evaporation. When water boils it is called ebullition.

The educational resource shows an interactive animation about the heat: heat is the transference of energy from one body to another.

Concept of recording the measurements

Concepto de fluorescencia

Concepto de ecuación de dimensiones.

Concepto de instrumentos digitales

Concepto de calor. El ODE muestra dos sistemas en el que uno (formado por partículas cuyo número es modificable) recibe calor de otro. Se define el calor como la energía que pasa de un cuerpo a otro, modificándose la Energía Interna de ambos.
