A journey through quantum secrets (from 9 to 12 years old) - Science Biennial

Explore quantum physics with experiments and dynamic games to understand concepts such as particle-wave duality and quantum entanglement.

General objectives of the activity:

· Relate different STEAM disciplines in one activity.

· Learn to solve problems that arise.

· Experiment with materials and games to visualize scientific phenomena in a practical way.

· Develop critical thinking and the ability to analyse situations from a scientific perspective.

Specific objectives of the activity: 

· Understand the basic concepts of quantum physics in a playful and visual way.

· Experience particle-wave duality and superposition through hands-on activities.

· To discover phenomena such as the tunnel effect and quantum entanglement through interactive games.

Syllabus 

· introduction: The activity begins with a brief presentation by the science educator and an explanation of what scientists do and how they investigate the world. The concept of STEAM will be discussed and a brief presentation will be made on what quantum physics is and its importance for understanding the behaviour of matter.

· Particle-wave duality: Through experiments, we will experience the difference between particles and waves. We will understand how, according to the phenomenon of particle-wave duality, particles can behave as both particles and waves, and we will see how each behavior differs.

· Quantum Hyperposition: We will understand how particles can exist in multiple states at the same time. By flipping a coin, children will see how the result cannot be known until it is measured. Then, with toy boxes and cats, we will introduce the concept of Schrödinger's famous experiment to explain the idea of quantum superposition.

· Tunnel Effect: We will explore the phenomenon of the tunnel effect, where particles can cross barriers that in theory they should not be able to overcome. Through experimentation, we will visually check how particles cannot pass through unless they are in a specific location. Then, we will do the experiment with a laser to demonstrate how waves can cross the same barrier.

· Quantum entanglement: We will learn about the phenomenon of quantum entanglement, where two particles can be connected to each other and influence each other, even at very large distances. Using colored cards, we will play an interactive game to show how one particle can determine the behavior of the other. We'll also use sticks to illustrate how, when particles are entangled, what one particle does affects the other.

· Farewell: Finally, we will resolve any doubts that arise about the concepts learned. We will make a small review of the quantum phenomena discovered and we will thank them for their participation, saying goodbye with a small reflection on the fascinating world of quantum physics.
