Below are the 2022 complete basic technology lesson notes for Jss 1 First term
Week 1
Topic: Understanding Technology
Outline:
- Introduction
- Technology related professions
- Importance of Technology
Introduction
Technology is necessarily not a new concept, it has been in existence for a very long time, but recently, there has been several advancement and modernization that is rapidly occurring, however, technology may be a term that is new to us but generally, it is describing something which is not new at all. Technology affects our daily life. We see its effect around us every day, even though we may not know what it is.
History enabled us to learn that villagers drank water from running streams or rivers or sometimes depended on rainwater whenever it rained. But today, we see wells that have some form of a machine to pump out the water instead of using buckets and ropes to draw water. This new development is called technology. To learn more, click here
Week 2
Topic: Safety Guidelines
Outline:
- Safety guidelines for pedestrians
- Safety guidelines for cyclists/motorcyclists
- Safety guidelines for the motorist
Safety guidelines are set of rules and regulations put in place to ensure that a person or product is safe and free from danger.
Discussions of safety often include mention of related terms. Security is such a term. With time the definitions between these two have often become interchanged, equated, and frequently appear juxtaposed in the same sentence. Readers unfortunately are left to conclude whether they comprise a redundancy. This confuses the uniqueness that should be reserved for each by itself. When seen as unique, as we intend here, each term will assume its rightful place in influencing and being influenced by the other.
Safety is the condition of a “steady state” of an organization or place doing what it is supposed to do. To learn more, click here
Week 3
Topic: Workshop Safety (1)
Outline:
- Causes of workshop accidents
- Types of workshop
- Prevention of workshop accidents
Meaning and causes of workshop accidents/hazards
An accident is defined as an unfortunate incident that happens unexpectedly and unintentionally, typically resulting in damage or injury. This then means that any harm or injury that is done to a student while s/he is in the workshop on a machine is called an accident. Accidents or hazards could be man-made or natural while it could also be accidental or deliberate. An accident is a negative experience that happens to somebody when he does not expect it.
The workplace can be dangerous, even more so in an industrial environment. Numerous factors can cause accidents, ranging from overexertion to the mishandling of hazardous materials. There is also a multitude of variables that can contribute to or influence a workplace incident. Think about this; 80 of every 100 accidents that happen in the workplace are ultimately the fault of the person involved in the incident. What does this tell us? Students are not taking the proper precautionary measures before working, or they are simply too lazy to be bothered with it. To learn more, click here
Week 4
Topic: Workshop Safety (II)
Outline:
- Safety rules and regulations in the workshop
- Safety devices
- Fire
Safety rules and regulations in the workshop
Before you can use equipment and machines or attempt practical work in a workshop you must understand basic safety rules. Workshop safety is everyone’s responsibility, the following rules have been put in place to ensure the safety of all students and staff. These rules will help keep you and others safe in the workshop, please read the safety rules carefully before entering the workshop.
Workshop rules
- Students affected by drugs or alcohol are not permitted in the workshop
- Students with any health problems that may affect workplace safety (e.g. medication, epileptic fits) must report these conditions to the workshop staff. To learn more, click here
Week 5
Topic: Properties of Materials (Wood)
Outline:
- Identification
- Classification
Identification
Technological advancement over the years has taken several shapes, sizes, and form. The materials used in creating a technological piece include wood, metals, ceramics, rubber, and plastics; these materials come in different forms and each form performs unique functions. We will be studying as many as we can, but starting first with wood.
Wood
Woods are identified by:
a. Their colour
b. Their classification into soft and hardwoods; Their property e.g. hardwood has broad leaves while softwood has needle-like leaves. To learn more, click here
Week 6
Topic: Properties of material – wood – (contd)
Outlines:
- properties
- Uses
Introduction:
Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic material, a natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. A living tree, it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to materials engineered from wood, wood chips or fibre. To learn more, click here
Week 7
Topic: Identification of Metals
Outline:
- Meaning of metals
- Properties of metals
- Forms of metals
Meaning of Metals
We have been discussing several materials that are very essential in the construction of technology, and this week we are going to be discussing another important material which is metal. Metals are another material used in the construction of things and they can be identified using their identity, colour/lustre, fusibility, magnetic effect, and conduction of heat and sound.
A metal is a material (an element, compound, or alloy) that is typically hard when in a solid state, opaque, shiny, and has good electrical and thermal conductivity. Metals are generally malleable—that is, they can be hammered or pressed permanently out of shape without breaking or cracking—as well as fusible (able to be fused or melted) and ductile (able to be drawn out into a thin wire). About 91 of the 118 elements in the periodic table are metals; the others are nonmetals or metalloids. Some elements appear in both metallic and non-metallic forms. To learn more, click here
Week 8
Properties of Metal (cont’d)
Outline:
- Classification of Metal
- Forms of Metal
Classification of Metals –
Earth is an abundant source of materials. The air we breathe, the water we drink, stones and rocks, and almost everything that is around us, are all useful to man for some purpose or the other. Gaseous materials like Oxygen, Nitrogen and Carbon dioxide are found in the atmosphere. Common salt and various other salts of sodium, magnesium and calcium are found dissolved in water bodies, like oceans, rivers and lakes.
The progress of civilization was first benchmarked by man’s increasing knowledge and usage of metallic deposits in the earth’s crust. Early man used stones, bones and wood to fulfil their requirements of hunting, cooking and building. The first metals to be found and used were copper, silver and gold as they could be easily extracted. By 2000 B.C. he acquired the knowledge of extracting iron from its ores by heating and this period came to be known as the “Iron Age”. Bronze was widely used for many years and this epoch of prehistory became the “Bronze Age”. As time went by, minerals were found to produce metals with different properties. These developments indicate a gradual change in the lifestyle of mankind. Today metals are so vital to modern man that it is unthinkable to live without them. To learn more, click here
Weeks 9 & 10
Topic: Properties of Ceramics, Plastics and Rubber
Contents
- Ceramics
- Plastics
- Rubber
A ceramic is an inorganic compound, non-metallic, solid material comprising metal, nonmetal or metalloid atoms primarily held in ionic and covalent bonds. A lot of us today live in modern houses with modern facilities. Most of our grandparents and great-grandparents did not enjoy some of the recent tools and equipment we have access to and enjoy. Today, many kitchens and household containers are made from clay and cement. These include cooking pots, water pots, etc. Clay and mud are also used in some places to make houses. The items made of clay and mud are called ceramics.
The earliest ceramics made by humans were pottery objects (i.e. pots or vessels) or figurines made from clay, either by itself or mixed with other materials like silica, hardened, sintered, in the fire. Later ceramics were glazed and fired to create smooth, coloured surfaces, decreasing porosity through the use of glassy, amorphous ceramic coatings on top of the crystalline ceramic substrates. Ceramics now include domestic, industrial and building products, as well as a wide range of ceramic art. In the 20th century, new ceramic materials were developed for use in advanced ceramic engineering, such as in semiconductors. To learn more, click here
