Chemical Properties of Carbon Compounds: Combustion

CBSE Class 10 Chemistry Chapter 4: Carbon and its Compounds. Carbon, in all its allotropic forms, burns in oxygen to give carbon dioxide along with the release of heat and light. Saturated hydrocarbons will generally give a clean flame while unsaturated carbon compounds will give a yellow flame with lots of black smoke. This is demonstrated with some examples.  

Allotropes of carbon

CBSE Class 10 Chemistry Chapter 4: Carbon and its Compounds. The element carbon occurs in different forms in nature with widely varying physical properties. Both diamond and graphite are formed by carbon atoms, the difference lies in the manner in which the carbon atoms are bonded to one another. Fullerene is another allotrope of carbon.  

Human Brain

CBSE Class 10 Biology Chapter 7: Control and Coordination. Is reflex action the only function of the spinal cord? Obviously not, since we know that we are thinking beings. The spinal cord is made up of nerves which supply information to think about. Thinking involves more complex mechanisms and neural connections. These are concentrated in the brain, which is the main coordinating centre of the body. The brain and spinal cord constitute the central nervous system.  

Tracing Evolutionary Relationships

CBSE Class 10 Biology Chapter 9: Heredity and Evolution. When we try to follow evolutionary relationships, how do we identify characteristics as common? These characteristics in different organisms would be similar because they are inherited from a common ancestor. Homologous and analogous characteristics are explained in this video.
