Concepto de los planetas del Sistema Solar.El ODE muestra una simulación donde se pueden ver los planetas del Sistema Solar orbitando alrededor de la Tierra. En la escena se pueden modificar las escalas de tiempo y espacio.

Concept of density

El movimiento de la Luna alrededor de la Tierra visto desde la Tierra o desde el Sol.

Description of a consumer unit.

Concept of electrical wire and conducting cable

Utilization of extension cords to carry an electric current to a place that is far from an electrical socket

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 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.

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.

Concept of recording the measurements

Confirmation of hypotheses concept. Scientific method

The movement of the electrons inside an electrical conductor of oscillating form.

Concept of attraction among masses

This visual represents the tracks left by two cars when they move at a constant speed.

Concept of calculating speed (II)

Concept of electric attraction. Which explains the interactions among electric charges.

Faraday's experiment

Concepto de energía química. El ODE ofrece información sobre qué es la energía química, qué posee energía química y cómo se transforma. Se acompaña esta información de una imagen que ilustra la definición.
