Design Technology - Year 9

Design Technology Overview

Term 1 + 2: Electronics - Speaker Project

Students will continue to develop their electronic skills by the circuit board for a speaker that can connect via an audio jack. They will learn about specific components as well as resistor calculations. The project will promote specialist hand skills and techniques during the soldering process. Once completed, the case for the speaker will be created to house the internal components safely and securely. During this project, both wood and plastic will be used to further develop the working properties of each material.

  1. Students will be assessed in three ways during this project. Firstly, students will be assessed on the success of their soldering. If the components have been soldered correctly and neatly, the speaker will work. Secondly, the design and fabrication of the casing will also be assessed. Lastly, a small end of project assessment linked to the theory behind the electronics will add to the end of project grade.
Soldering

This is the process by which a connection is made from component to circuit.

PCB

The Printed Circuit Board is what holds all the components in the correct place so our electronic devices work as they should.

Solder

This is the material needed to join component to PCB. It is heated up and applied to the join and left to cool.

Soldering Iron

The equipment needed for soldering. The tip gets hot and melts the solder in place.

De - Soldering Iron

If a mistake with the soldering happens, a de-soldering iron can be used to remove the incorrect soldering joint.

Resistor

Resistors are used to reduce current flow within a circuit.

Capacitor

A device that stores electrical energy in an electric field within a circuit.

IC Chip

An IC is a collection of electronic components: resistors, transistors, capacitors, all integrated into a tiny chip.

Develop the individual:

Students will be able to develop their hand skills and their ability to work with small tolerances and to more in depth detail and quality.

Create a supportive community:

Students will be working in small groups which promote teamwork and accountability; these are useful life skills that can be used in all aspects of life.

Terms 3 + 4 : Pewter Metal Casting

Students will learn about the working properties of variety of metals which include some ferrous, non ferrous and metal alloys. They will study different metal manufacturing techniques including milling and casting. The practical element of this project will be to design and make a mould for pewter to be cast in. They will produce a small metal ornament by heating up and casting the pewter themselves. Students will also learn about a conductive paint that could be incorporated into the future of electronics.

  1. The assessment for this project will be based on the variety and quality of design work, the use of CAD and CAM as well as the final outcome of the practical element. Additionally, a small end of project test will assess theory knowledge which is based around the technical elements of metal as a material.
Composite Material

A material made from two or more constituent materials with different physical or chemical properties. When combined they produce a material with different characteristics.

Quality Control

The process of checking work to make sure it is of a good quality.

Ferrous Metals

Metals that contain iron and are magnetic.

Non Ferrous Metal

Metals that do not contain iron are are not magnetic.

Casting

A manufacturing process that pours molten or liquid material into a mold to cool, set and create an object of shape.

Alloy

A mixture of at least two metals combines together to produce a new material, usually one that is stronger.

Bare Conductive

A company that provides a paint that can carry an electric current due to its carbon content.

Develop the individual:

Students will be working with metal and looking at how manufacturing takes place at an industrial level.

Create a supportive community:

Students can compare and contrast their own designs with others in the workshop. They will be able to peer assess each other's work to develop their own skills by drawing inspiration from those around them.

Terms 5 + 6 : Design portfolio

Students will be introduced to a real life design brief. This project will guide the students through the process of getting a product to market from start to finish through the completion of a design portfolio. It includes conducting some initial research into a gap in the market, studying materials to make the most appropriate selection and then the opportunity to design and make it. Students will then be able to produce some design ideas that meet the requirements of the client they have chosen. Going through the development of a product through listening to a client's needs and wants will develop their ability to listen to problems and design a product that solves a problem.

  1. Students will be assessed on their ability to present their research findings, the presentation of their design ideas, the uniqueness of their solutions and the thought process in developing it through feedback from a client of their choosing. and willingness to contribute to the group work, as well as the quality of their written and design work. As well as this, an end of year test which includes theory work from all projects conducted over KS3 will assess how with the students have engaged and retained some of the most important aspects of design and technology, which will include wood, plastic, electronics and drawing techniques.
Graphene

A material that is about 100 times stronger than the strongest steel and it conducts heat and electricity very efficiently and is nearly transparent.

Titanium

Of silver color, low density, and high strength. Titanium has a very high resistant to corrosion.

Metal Foam

A metal foam is a cellular structure consisting of a solid metal (usually aluminium) with gas-filled pores comprising a large portion of the volume. This can advance the materials properties.

Nano Materials

A material of nano scale dimensions.

Hydrochromic Material

A smart material that changes its properties when it comes into contact with moisture.

Thermochromic Material

A smart material that changes its properties when there is a change in temperature.

Electrochromic Material

A smart material that changes its properties when an electrical current is passed through it.

Photochromic Material

A smart material that changes its properties when it comes into contact with UV light.

Smart Materials

Materials that are able to change their properties when an external stimuli changes, such as stress, heat, moisture and others

Modern Materials

A modern material is a material that has been engineered to have improved properties.

Develop the individual:

Students will be working to a real life brief which will give them experience on how designers work in industry. As well as this, the design museum manufactures and sells the best ideas from previous student entries in their shop and donate the profits to charity.

Create a supportive community:

Students will develop a better understanding of how design work is conducted in industry, and they should appreciate what it takes to get some of the products they own manufactured.
