Heart Chambers Human heart has four chambers: - Upper two chambers - right and left auricles - Lower two chambers - right and left ventricles Auricles or Atria (Receiving chambers of heart) Auricles are the receiving chambers of heart. They have comparatively thin walls. The right auricle receives deoxygenated (impure) blood from the whole body by two large vessels, the superior and inferior vena cavae (sing. cava). The left auricle receives oxygenated (pure) blood Their walls are thicker than those of auricles. the whole body.

Theme : Matter is composed of atoms/molecules and is found in the forms of solids, liquids and gases. These states are compared on the basis of interparticle space and interparticle collision. The kinetic theory of matter has been postulated to explain the change of state. In a physical and chemical change, the total mass before and after the change remains the same which is known as the law of conservation of mass. The knowledge of this theory and law further helps in understanding other behaviour of matter. LEARNING OUTCOMES The children will be able to : describe the main postulates of kinetic theory of matter. explain the reason of change of one state of the matter to another and vice-versa on the basis of interparticle space and interparticle attraction and collision. define and explain the law of conservation of mass using an example. INTRODUCTION WHAT IS MATTER ? We know that chemistry is the branch of "Matter is anything which has mass, science that deals with the study of various occupies space and can be perceived by our kinds of matter, which includes their structure, senses." composition and physical and chemical properties. If we look around us, we see a number of things like, stones, sand, clay, water, minerals, - A bag is made up of plastic. plants, animals, pens, pencils, books, etc. They - A dress is made up of cloth. are all made up of different types of materials - A hammer is made up of iron. and are called "matter" in science.
