La mémoire et quelques méthodes pour apprendre ses leçons

Children live with a heart without really knowing what it does. They usually know that it is related to blood, but what exactly is it? The heart is an organ that allows the body to live. It keeps the blood flowing through the body by pushing blood out into the arteries and then back into the veins. The heart is a hollow muscle and it…

Today we meet again for a video on the internal activity of the Earth. Students will discover what goes on in the bowels of the Earth. First of all, the Earth is made up of nested shells: the continental or oceanic crust, the upper mantle, the lower mantle, the outer core and the inner core. There is a lot going on inside the Earth! …

In this video, the question is whether it is possible to catch a rainbow. The children learn that the rainbow is the result of the white light of the Sun passing through the water. Thus, for a rainbow to be visible, the Sun must be low in the sky and the observer's back to the Sun and facing the rain curtain. The water decomposes…

After studying the school of the past, this video aims to understand a representation of the passing of time. Through the testimony of a grandfather, students discover what society was like at the beginning of the 20th century, especially in the countryside. The evolution of objects over time allows us to understand how previous…

After seeing the dangers of electricity, this video distinguishes between electrically conductive and insulating materials. The idea is to understand that a conductive material allows the current to flow. I then present several experiments that allow us to verify if an object can conduct electricity or not. From these experiments, we…

When we think of air, many questions arise: Does air exist? Can we catch air? What is the purpose of air? Is air matter? This video will answer some of these questions. It attempts to show the existence and materiality of air through experiments that can be done at home. Although air is invisible, students can see that air occupies…

This video aims to better understand and implement some basic hygiene rules. This requires a knowledge of the micro-organisms that are around us. A distinction between useful microbes and disease-carrying microbes is made so that we do not fear all microorganisms. The video also helps to understand why we wash our hands, body, teeth…

But where does the food we eat every day come from? This is the question that the video tries to answer. Children will discover the origin of our food (animal, vegetable, mineral). It is an opportunity to realize that between unprocessed food and our plates, there are intermediaries. I decided not to put images that would be too…

Biodiversity is a topical issue that needs to be explained so that students are aware of the need to protect their environment. Students can discover that biodiversity is all living things (animals, plants, bacteria, humans, fungi, etc.) interacting with their environment. Food chains are part of biodiversity. It is this biodiversity…

Students learn to recognize a cell and the fact that it represents a common structure among living things. This video gives general information about the cell that will be expanded upon in the rest of the schooling. All living things are made up of cells, this is what we have in common. Some living beings have only one cell, they are…

After learning about the 3 main diets, the aim is to understand the food relationships between animals. Students learn that a food chain is a sequence of living things in which each one eats the one before it before being eaten by the one after it. The food chain usually starts with a plant and then a vegetarian or omnivore and then…

What is the point of eating? Where does our food go? These are all questions that you may be facing from your children. I have tried to cover the important steps that lead food to be transformed into nutrients. The food then goes through a first stage of chewing to be reduced. Swallowing allows it to pass to the stomach through the…

This video consists in discovering germination. It is based on experiments that have been done in class and that can be reproduced at home. The children learn to recognize the conditions in which germination takes place. Then they identify the needs of the plant to grow. The children also learn to recognize the components of a seed …

The question of the birth and origin of living beings is a recurrent one among students. This video aims to answer some of the questions they have about the birth and life of living beings. Thus, the students will be able to discover the different stages of life from birth to death. I insist on the notion of cycle to reassure them. In…
