The educational resource shows a visual about the planets: in addition to our planet, there are another eight planets travelling around the sun.

The educational resource shows a visual about the Milky way: you can manipulate our galaxy in the following visual to see its characterstics.

The educational resource shows how the energy is the capacity to produce changes in the environment by doing work or transferring heat. This means that when a body transfers heat or does work, its energy decreases.

In the following visual you can observe how the rotational axis of the earth is inclined; when the North Pole is furthest from the sun, the South Pole is nearest the sun and vice versa.

The following visual explains the precautions that should be taken into account when dealing with electricity

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 study of matter allows us to encompass the known universe in a range of sizes and distances with lower and upper bounds.

Las tablas de valores resumen de manera organizada un movimiento.

Concept of tables and graphs in accelerated movements

Concepto de tablas y gráficas en movimientos variados. A la vista de la tabla de valores, puede deducirse cómo será la representación gráfica.

The educational resource shows information about the solar energy and its advantages and its disadvantages.

The educational resource shows a visual about the eclipses: eclipses of the sun and moon are caused by the moon crossing between the sun and the earth (solar eclipse) or by the earth crossing between the sun and the moon (lunar eclipse).

El ODE muestra dos escenas con las que se puede estudiar los planetas que forman el sistema solar y su movimiento alrededor del Sol. Se puede modificar la visualización o no de las órbitas, el que aparezcan los nombres de los planetas y ver los movimientos desde el punto de vista de la Tierra.

The material world which our eyes cannot observe is known as the microscopic scale of observation (cells, atoms, molecules, etc.)

Los cables conductores ofrecen resistencia al paso de la corriente eléctrica.

The residual current circuit breaker (RCCB) is one of the elements of a consumer unit. The following visual explains its function.

El ODE muestra una escena interactiva donde aparece una gráfica fuerza/ desplazamiento correspondiente a la acción de una fuerza sobre un objeto. Se permite variar la fuerza aplicada y el desplazamiento que provoca con el objeto de calcular el trabajo que realiza dicha fuerza.

Renewable energy sources are those which after being used can be regenerated naturally or artificially. The following pictures are graphic examples rof enewable energy sources.

The educational resource shows a visual about the relative movement of the Earth: our planet is enormous compared to a train, which is why although all the earth moves, it seems to us to be still, and the sky around it the one that moves.

Los resultados de las medidas realizadas en los experimentos suelen agruparse, para que podamos verlos "de un vistazo". Las tablas de datos constituyen una forma habitual de registrar las medidas realizadas en una investigación científica.
