The kinetic theory of matter explains the behavior of matter in terms of the motion of its particles. According to this theory, matter is composed of tiny particles (atoms, molecules, or ions) that are constantly in motion. Changes in states…
Melting When a solid is heated, the particles acquire more kinetic energy and vibrate more vigorously. Eventually, at a certain temperature called the melting point of the solid, the force of the vibrations overcome the binding forces and solid structure…
Kinetic molecular theory is useful in describing the properties of solids, liquids and gases at the molecular level. Kinetic theory of matter assumes that matter is made up of tiny particles such as atoms, molecules and ions that are continually…
Kinetic energy is a form of energy that an object possesses due to its motion. It is defined as the energy an object has because of its mass and velocity. The formula for calculating kinetic energy is: Kinetic Energy Kinetic…
Life Span continuum refers to series of similar events that takes place throughout the length of time a person is likely to live.
Communication Techniques Communication is the process of giving, receiving and understanding messages. It involves exchanging ideas, understanding, listening, expressing oneself, talking and using body language, facial expression and a host of other behaviours. Types of communication: 1.Verbal Communication; This is…
When an object is dropped from above the ground, work is done as the object is pulled to the ground. As the object is falling and work is done, the potential energy of the body is changed to kinetic energy.…
Potential Energy Potential energy is the type of energy possessed by a body due to its position. A stone on the ground does not have energy so long as it is lying on the ground. The stone cannot be seen…
The concepts of work, energy, and power are fundamental in physics and are closely related to each other. Let’s explore each concept individually: 1. Work In physics, work is defined as the transfer of energy that occurs when a force…
Energy is used up when work is done. The energy stored up in our muscular system is made available when we do work. The stored-up energy (potential energy) is converted to kinetic energy as work is being done. Meaning of…
Meaning of Body Image Body image refers to the way a person feels about his or her physical appearance. People have differences in their physical appearances,some of these are in term of: 1. Height 2. Size or shape of the…
Pubertal changes could be physical ,emotional,social and internal.These changes must be well handled In Adolescents. Adolescents often enter puberty with a heightened sense of sexuality accompanied by a great deal of confusion.At this stage,they are faced with the challenges of…
Puberty Puberty is the transitional biological stage between childhood and adulthood. It is the stage when the body matures.Puberty involves changes in primary sexual characteristics. It starts when the pituitary gland at the base of the brain produces hormones. Hormones…
The developmental changes could be permanent or temporary.permanent changes are irreversible.Examples are the changes that occur during body growth i.e those features associated with the development stages of child hood,Adolescence and Adulthood are the permanent changes. Temporary changes may…
Growth is the progressive increase in the size of a child or parts of a child. Development is progressive acquisition of various skills (abilities) such as head support, speaking, learning, expressing the feelings and relating with other people. Growth and…
The human brain possesses qualities that have no parallel in the animal world. One consequence is man’s explicit mental capabilities. Man possesses the faculty of speech, and his creative communication using his vocal system is completely different from that of…
An Ecological relationship is the relationship between organisms in an ecosystem. All organisms in an ecosystem are connected. Each interaction depends on the one before it. Each population interacts with one another in a complex web of relations. Ecological relationships…
Adaptations are special features that allow a plant or animal to live in a particular place or habitat. The ability of living organisms to adjust themselves to their surroundings is called as adaptation. Adaptations are the changes in structure or…
This coral reef in the Phoenix Islands Protected Area is a rich habitat for sea life. Few creatures make the ice shelves of Antarctica their habitat What is an Habitat? A habitat is an ecological or environmental area that is…
