Computer Science – 10th November 2014

Last week you looked at creating a document to teach oasis about Input/Output devices.  You had to research the devices, state what they are get a picture of each device. You will get questions like this in the exam.

How much did you actually remember?  Look at the statement below and state what each item is.  Use full sentences and give examples and pictures.

Using MS Word  you must create a document to teach the Oasis group about computer input, output and control devices. Remember to put your name and form in the header and the title below.

Using the list below you will have to research what they are, get an example picture of each and write an explanation of what they do (appropriate for children to understand).

The Purpose is to Educate

The Audience is Oasis (children)

The Title is Computer I/O Devices


Input – Allows you to put information into the computer (text, images, audio)

Output – Allows the computer to communicate information to you (Text, images, audio)

Control – A computer uses inputs to sense what is going on (through light, heat sound etc) then changes its environment through outputs based on what the programmer wants (eg. If the sensors show it is too cold then turn the heater on)

Here is a list of devices you can talk about.  You will have to research what they are, get an example picture of each and write an explanation of what they do (appropriate for children to understand)

Laser Pointer
Inkjet Pinter
Dot Matrix Printer
Graph Plotter
Temperature Sensor
Pressure Sensor
Light Sensor
Graphics Tablet
Bar Code reader
Video Camera
Web Cam
Light Pen




KS4 IGCSE ICT – October 13th 2014

Starter: in pairs discuss – Why don’t we live in caves anymore?


Know what evaluation means.

Understand why we evaluate and how it helps us.

Be able to evaluate our work and suggest improvements.


Last week we looked at Audience and Purpose.  What can you remember about that?

Is an umbrella with holes in it FFP?  Would bad language be appropriate if you were speaking to an Imam, priest or spiritual leader?

Lets look at the presentations that you created last week.  

The Audience was Adults

The Purpose was to Educate

and the Topic was ‘The Importance of Backing Up’


Let us evaluate our work.  Look at the following and state whether they are appropriate.  Remember to say why you think so.

Language you have used. 

Back ground colours.

Forground colours.



Suggest at least three ways to improve your presentation.

KS4 IGCSE ICT – October 6th 2014

Know what ‘Purpose’ means.

Understand why we must think of our audience whenever we create a document.

Know how to create a document that is ‘FFP’ and ‘AA’.


Lets have a look at how not to do it.  Click on the Worst Presentation Ever for some hints and tips.


Different audiences have different needs. Imagine you were creating an educational presentation to teach people about Backing storage and the need to back your data up.

What type of language would you use for children below 13? Big complex words?

What type of language would you use for adults? Simple words?

What type of images would you use for children? Cartoony?

What type of images for adults? Real?

What types of colours would you use?

What about fonts?  How many different fonts would you use and why? (Think about headings, sub-headings etc.)


Create a power point presentation that will educate adults about the importance of backing up their information.  Use what you have learnt over the past few lessons to suggest the type of storage and media for different needs (e.g. one for there phone data, one for their mp3s another for their computer…)

It must be at least six slides and give reasons for your choices.


Topic:   The importance of backing up

Audience: Adults

Purpose: To educate and inform

learning objectives

1) know and understand how to draw basic shapes geometrical shapes using a graphical programming language

2) Understand how written algorithms can be translated into a graphical programming language

read  pages on

KS3 Computer Science

KS4 IGCSE ICT – September 29th 2014


Thinks about this.  How would you make sure that you did not loose your photos and music on your computer?


Know what storage devices and media are.

Understand difference between various devices and media..

Be able to identify different storage types and their properties.


So where would we store our data?

How often should we ‘back it up’?

What is the best device to use?


1.  On the board we will write a list of all the things at home that can store electronic information (not just the computers).

2.  On your sheets write down how mane files you own of each type (from the chart on the handout)

3.  Work out how much information do you own?  Work this out using the hand out.

4.  Which device would be the most appropriate to store the information that you own?


Have a look at the information in the following link.  Click through the  links and  read each section carefully (there will be questions to answer ).


Download this document on Backing storage to your work area.  Fill in the missing information for each one of the storage devices or media.  You can use the link above to do your research, or try google.





KS4 IGCSE ICT – September 22nd 2014


Last week we looked at the insides of a computer.  The Hardware.  Can you remember what we found?

Have a look at this to remind you.


Know what an Operating System is.

Know what Hardware and Software are.

Understand the difference between Hardware and Software.

Be able to explain what hardware is required to build a computer


The IGCSE ICT Syllabus states that we should be able to…

  2. define software, giving examples;
  3. describe the difference between hardware and software;
  4. identify the main components of a general-purpose computer:
    • central processing unit (CPU),
    • main/internal memory (including ROM and RAM),
    • input devices,
    • output devices,
    • secondary/backing storage.
  5. identify operating systems, including:
    • graphic user interface (GUI),
    • command-line interface
  6. identify different types of computer including:
    • personal computer (PC) or desktop
    • mainframe
    • laptop
    • palmtop
    • personal digital assistant (PDA).

Today we are going to look at Hardware and Software.  What are they? What do they do? Why do we need them?  Lets find out…


Part 1

Click on this link and read through the page on hardware and software.  You can also watch this video to give you more information on hardware.

You work at Circuit City, a large electronics shop that sells all the latest computers, laptops and programs.  You have to deal with customers every day.  Some of these customers have never used computers before an will be relying on your expertise to guide them in the right direction.  Answer question one and two  on computer hardware using the work sheet.

Part 2

You’ve sold the customer the basic computer system.  They will need some peripherals to get it to work properly.  Click on the link to learn about input and output devices.  Now answer answer questions 3 and 4.



What else do you think the customer will need to use their computer effectively?
