In this opportunity we will explore the planet of emotions. We will begin by defining what they are and understanding that they can be very changeable and unpredictable. Through specific situations, we will stimulate feelings, in order to understand that they are very diverse and even complex, depending on the scenario presented. And we will also learn that our body reacts in different ways according to the emotion we experience. Then we will know that words are a wonderful means to express our emotions and feelings to other people, although sometimes it becomes confusing what we are feeling. For that a "Planet List" will help us to understand what is what we actually feel through some simple practices. That takes us to "emotional intelligence" that is based on intelligently controlling our emotions. We will see how to do it. Finally, when living surrounded by people, we must know that they also have feelings, which we will learn to identify through their body language and we will understand the importance of recognizing emotions in others. The feelings are an important element that give a special meaning to life and even light the spark of art and great ideas that could change humanity.
