ANIMALS
Animals are classified as wild and domestic animal.
Domestic animals are animals that live with us at in our home,school compound and environment which we care for and they are not harmful to us. Domestic animals can also be called a friendly animal. While wield animals are animals that live in the bush. They are dangerous to human.
EXAMPLES OF DOMESTIC ANIMAL: Dog, goats, cow, cattle, rabbit etc
EXAMPLES OF WILD ANIMALS: Elephant,tigers,hyenas,lions ,snakes etc
BASOC COMPARISON OF PLANT AND ANIMALS AS LIVING THINGS
Plants are green in colour due to the presence of the chlorophyll and are able to prepare their own food with the help of sunlight, water and air. They are known for providing oxygen to the atmosphere. Animals are the living organisms which feed on the organic material and are known to have a specialized system in their body like the nervous system, reproductive system, sense organs, which make them unique from the other forms of life.
Movement
Plants do not have the ability to move from one place to another, as plants are rooted into the ground, exceptions are Volvox and Chlamydomonas. Animals can move from one place to another freely, and exceptions are Sponges and Corals.
Mode of nutrition
Plants have chlorophyll, due to which they have the capability to prepare their own food and are known as autotrophs.
Animals are the heterotrophs, as they depend on plants for their food, either directly or indirectly.
Storage of food
Plants do not have the digestive system, and the storage of food (carbohydrate) takes place in the form of starch. Animals have the proper digestive system which support the food in digesting and absorbing nutrition from it, the food (carbohydrate) is stored in the form of glycogen.
Respiration
Plants take in carbon dioxide and release oxygen into the atmosphere, exchange of gases occurs through stomata.
Animals take in oxygen and release carbon dioxide into the atmosphere, which occurs through lungs, gills, skin, etc.
Cellular structure
The cellular structure of plants contains the cell wall, chloroplast, plasmodesmata, plastids and other different organelles.The cellular structure of animals does not have cell walls, though other organelles like the tight junction, cilia are present.
Growth
The growth of the plants takes place throughout the life, the meristematic system present in the tip of roots and stems supports the growth.The organs and organ system supports the growth and is definite.
REPRODUCTION
Reproduction of plants takes place asexually like by budding, vegetative methods, spores, wind, or through insects. Some lower animals like algae reproduce asexually while higher animals reproduce sexually.
Response
Plants show the response to stimuli like touch, light, though are less sensitive due to the absence of the sense organs. They have proper nervous system and response to any stimuli in a fraction of seconds, so they are regarded as highly sensitive.

WEEK 2
Topic: Animals
Subbtitle: Characteristivs of living things

Characteristics of living things
There are seven activities which make organisms different from non-living things. These are the seven characteristics of living organisms.
1 Nutrition
Living things take in materials from their surroundings that they use for growth or to provide energy. Nutrition is the process by which organisms obtain energy and raw materials from nutrients such as proteins, carbohydrates and fats.
2 Respiration
Respiration is the release of energy from food substances in all living cells. Living things break down food within their cells to release energy for carrying out the following processes.
3 Movement
All living things move. It is very obvious that a leopard moves but what about the thorn tree it sits in? Plants too move in various different ways. The movement may be so slow that it is very difficult to see.
4 Excretion
All living things excrete. As a result of the many chemical reactions occurring in cells, they have to get rid of waste products which might poison the cells. Excretion is defined as the removal o toxic materials, the waste products of
metabolism and substances in excess from the body of an organism.
5 Growth
Growth is seen in all living things. It involves using food to produce new cells. The permanent increase in cell number and size is called growth.
6 Reproduction
All living organisms have the ability to produce offspring.
7 Sensitivity
All living things are able to sense and respond to stimuli around them such as light, temperature, water, gravity and chemical

FORMS OF TECHNOLOGY
Technology is something which needs our eyes on. The latest technology changed a lot from what we saw in the last decade or the past century. New machines and gadgets are invented to make the jobs easier like never before. From the little tailor machine to the fastest car in the world, all got automated reducing the manual actions required to the least. Modern technology schools made it easier for the students to extract the possibilities of the latest tech inventions. Their impact is enormous in crafting a perfect generation who are expertized in the current technology stuff.Technology can be the knowledge of techniques, processes, and the like, or it can be embedded in machines to allow for operation without detailed knowledge of their workings.
TRADITIONAL TECHNOLOGY
Traditional technology was used before the Internet and mobile phones
Examples of traditional technology
Overhead projector
Plough
Type writer
(farming with hoes and cutlass
using of town crier, useof stones to make fire,use of donkeys for transportation etc)
MODERN TECHNOLOGY
What is Modern Technology?
Modern technology is the advancement of the old technology with new additions and modifications. For an example, it is impossible for the people in this decade to live with a wired telephone placed on the table. So, the mobile phone which can be taken with us anywhere is the perfect example of the technology advancement or simply, the modern technology. Any machine or device we see around us is the product of the modern technology. To know more about it, continue reading this article.. Modern technology used the Internet and mobile devices and allows people to use it faster than the traditional technology.
