Key ideas

The universe consists of four elementary building blocks: protons, antiprotons, electrons and positrons. Protons and positrons are positively charged. Antiprotons and electrons are negatively charged. Particles move in straight lines when not interacting.

Particles interact in three ways.

​

​

Repulsion

Formation of atoms

Annihilation

Who wants to play a game?

Game rules

Remember:

  • Walk slowly
  • Freeze if I clap
  • No talking except when interacting

You will take the role of protons, antiprotons, electrons and positrons, as indicated on the sticky notes. �You move in straight lines when not interacting.�You interact by shaking hands. Charged matter cannot interact with neutral matter.

​

Repulsion: Continue in a different direction

Formation of atoms: Create a bound system by linking arms.

Annihilation: Sit down

What happened?

  • Matter and antimatter formed atoms and antiatoms
  • Antimatter and matter was annihilated
  • A slight imbalance at the beginning affected the result

​

10 of 13

  • Positron can be misinterpreted as proton
  • Referring to proton as elementary particles
  • If antimatter has reverse charge of matter, then does Antimatter has reverse look from matter? How would the colours be?

​

STUDENTS’ CONCEPTION & CHALLENGES

11 of 13

  • Is there any antimatter left from Big Bang? What will happen if the antimatter touches matter?
  • Understanding the rules of the game and to carry out effectively
  • How to we see antimatter? Do we need special glasses?

Helpful Material and Resources

  • Young age & challenge

​

  • First talk about antimatter : all first ideas comes from science-fiction.

​

  • Resources clarifies misconceptions

​

  • Using simple examples, then show the real science facts.

​

  • More Modern Physics at younger age

​

  • Increasing the chances - amount of interest in STEM education.
