INFORMATION ABOUT THE SMALL IDEA

Energy > Energy and forces > Energy and mass 

Einstein's theory of special relativity shows that matter (as mass) and energy can be converted into each other according to the famous equation E = m c^2. Energy can be converted to mass (e.g. pair production) and vice versa (e.g. annihilation).

Connection to Big Idea about forces: A force acting on an object will cause its acceleration or change of shape. Under the description of Special relativity for velocities close to the speed of light the mass of the object increases.

Connection to Big Idea about the universe: The entire Universe is made up of energy and matter. However, around 95% of this we can’t actually see, we call this dark energy and dark matter.

Connection to Big Idea about quantum: Quantum theory restricts energy to discrete values (quanta). For subatomic particles, mass can transform to energy and vice versa through different subatomic phenomena.

About

PLATON is a two-year European project launched on September 2016. It aspires to provide teachers and school communities with a coherent teachers’ training framework which will update their current teaching practices. More particularly, PLATON aims to offer an open and innovative training framework to teachers of primary and secondary education which will focus on:

  • Promoting student-centred teaching approaches;
  • Promoting a holistic interdisciplinary approach;
  • Support the use of online educational tools;
  • Support the meaningful collaboration between teachers of the same school.
