Construction Technology: How Buildings Are Planned and Built – Construction technology is the knowledge of how to plan, build, finish and look after structures. A building has a foundation, a frame (columns and beams), walls and a roof. Every load (dead load of the building itself, live load of people and furniture, wind and snow) must travel down a clear load path to the soil. Concrete is strong in compression, steel in tension, so reinforced concrete uses both. Builders work from scale drawings (plan, elevation, section), use maths to find areas and volumes, follow building codes for safety, and fit systems for water, power and air.

2. B. Design, Layout, and Planning Skills

Solutions: How Things Dissolve and How Much Can Dissolve – A solution is a uniform mixture of a solute dissolved in a solvent. In water (an aqueous solution) the solute breaks into particles too small to see, so it never settles and passes through filter paper. Concentration tells how much solute is present (mass % = solute ÷ solution × 100). Solubility is the most that can dissolve in 100 g of solvent at a given temperature; beyond it the solution is saturated. Evaporation, crystallisation and distillation separate solutions.

Data Analysis – Data analysis means turning raw data into answers. It follows a cycle: ask a question, collect data, clean it (remove errors, repeats and blanks), organise and transform it, analyse it with summaries such as mean, median, range and patterns, show it with a good chart, and draw a careful conclusion. Watch for outliers, small samples and bias, and remember that a correlation between two things does not prove that one causes the other. Data must also be stored safely and used with permission.

4. D. Technology,the Environment, and Society

Environmental Stewardship: Caring for the Planet as We Use Technology – Environmental stewardship means using the Earth's resources carefully so they last, and fixing harm where we can. Every product, from a phone to a hospital machine, has a life cycle: raw materials, making, transport, use and end of life. Each stage uses energy and makes waste. Good stewards keep products longer, choose efficient machines, follow the waste hierarchy (refuse, reduce, reuse, recycle, then dispose), send e-waste to proper recyclers and support laws and company practices that protect nature. Technology can harm the environment, but it can also help: solar panels, LEDs and smart sensors cut waste.

5. E. Professional Practice and Career Opportunities

E1 Health and Safety · E2 Career Opportunities

Health and Safety: Hazards, Risks and Controls – A hazard is anything that can cause harm. Risk is how likely the harm is and how bad it would be: risk = likelihood × severity. A risk assessment finds hazards, decides who could be harmed, rates the risk, adds controls and is reviewed. Use the hierarchy of control: eliminate, substitute, engineering controls, admin (rules, training, signs), then PPE last. Safety signs use colour and shape. Workshops, art rooms and workplaces need guards, ventilation, labelled materials, clear exits and first aid. Laws in most countries make employers and workers share the duty to stay safe.
Career Planning: From Knowing Yourself to Your First Job – Career planning has five steps. 1) Know yourself: interests, skills and values. 2) Explore career families and find out the work, study needed, pay and demand. 3) Plan a pathway with SMART goals and a plan B. 4) Search for jobs with a CV, cover letter, digital portfolio and interview practice. 5) Make the move from school to work and keep learning, because careers change over a lifetime.
