The “Big Ideas of Science” is a set of cross-cutting scientific concepts describing the world around us and allowing us to conceive the connection between the different natural phenomena. The Big Ideas aim to help students understand the link between the different subject domains, as well as between the subjects they are taught in school and their “real-life” experience. In the Go-Lab Sharing Platform, the online labs and Inquiry Learning Spaces (ILSs) are classified according to the eight Big Ideas of Science presented below.

Furthermore, using the online tool of the PLATON project (, you can discover the Big Ideas of Science in an interactive way.

Energy can neither be created nor destroyed. It can only be transformed from one form to another. The transformation of energy can lead to a change in state or motion. Energy can also be converted to mass and vice versa.
Evolution is the basis for both the unity of life and the biodiversity of organisms (living and extinct). Organisms pass on genetic information from one generation to another.
There are four fundamental interactions/forces in nature: gravitation, electromagnetism, strong nuclear and weak nuclear forces. All phenomena are due to the presence of one or more of these interactions.
At very small scales, our world is subjected to the laws of quantum mechanics. All matter and radiation exhibit both wave and particle properties. We cannot simultaneously know the position and the momentum of a particle.
Cells are the fundamental unit of life. They require a supply of energy and materials. All life forms on our planet are based on this common key component.
Earth is a very small part of the universe. The Universe is comprised of billions of galaxies, each of which contains billions of stars (suns) and other celestial objects.
Earth is a system of systems which influences and is influenced by life on the planet. The processes occurring within this system influence the evolution of our planet and shape its climate and surface.
All matter in the Universe is made of very small particles. They are in constant motion and in constant interaction with each other. Elementary particles form atoms and atoms form molecules.
