You must be able to: 5SE MATHS SKILLS AND SCIENCE KNOWLEDGE TO ANSWER QUESTIONS RELATED TO $ESIGN 4ECHNOLOGY

s

Some of the exam questions for GCSE Design & Technology will use skills and knowledge that have been learned in maths and science.

The following table summarises the maths skills and science knowledge that might be needed. It also gives some examples of how the maths skills might be used in questions in the exam.

There are lots of practice questions that include maths skills in the relevant sections of this book. Look for the maths skills logo:

Use decimal and standard form appropriately when using metric units and units of mass, length, time, money and other measures (for example 3.2 Ă— 103 m).

Calculate quantities and sizes of materials.

Calculate costs of materials or energy sources.

Select materials based on their mechanical properties or calculate properties needed.

Calculate tolerances and seam allowances.

Understand and use ratios in the scaling of drawings.

Analyse provided tables and charts of data, such as survey responses and user questionnaires.

Calculate percentages such as profit or waste savings.

Calculate changes in the magnitude of forces when using mechanical devices.

Calculate gear ratios.

State the composition of important metal alloys.

Use percentile ranges from anthropometric or ergonomic data to make design decisions.

Determine quantities of materials needed, used or wasted.

Calculate the volume of cuboids, and simple and composite shapes.

Construct frequency tables using provided data.

Interpret the meaning of data presented in frequency tables, for example to select materials or to determine user preferences from survey data.

Present information on design decisions or client survey responses.

Create tables of results and findings during prototype development.

Review Electronic Systems 2

A design is being produced for a doorbell system. A programmable component is to be used to control how the system works. The programmable system must: t Detect when a switch has been pressed. t Activate a buzzer for a period of 5 seconds after the switch has been pressed. t Turn off the buzzer after the time period has ended. t Turn on a lamp after the buzzer has stopped sounding.

Write a program that meets the needs of the doorbell system described above. You may use any programming language that you are familiar with.
