A missing word activity to introduce simple Ciphers based on a short video clip. Used with Year 10 GCSE Computer Science : System Security / Data Representation

Used with Year 10 GCSE Computer Science students - covering Data Representation unit

Resources for GCSE Computing course for the Data Representation topic. The Resource explains how different data is stored, so introducing data types and variables and shows how important it is to make sure the correct variables are selected by the programmer. Uses examples in Python and an excel program ( input form and vba coding) has been created for students to investigate for themselves, what can go if wrong data types for variables are chosen by the programmer. Overflow error, type Mismatch, rounding up errors, Validation etc.

Quick revision s on wave properties, bit rate, bit depth and file size

Resource shows how to build a circuit with leds, distance sensor and a buzzer using a breadboard and how to program using Arduino. Explains how distance ultrasound is used to measure distances in introduces a sequence of if statements to create a reverse parking sensor which uses sequence of lights and alternating tones from a buzzer to simulate a parking sensor using Tinkercad. Introduces for loops to control brightness of an led and changing the tone of a buzzer. Explains how Square waves can be used to output analogue data. Used for year 9 to make coding more engaging in preparation for choosing Computer Science at GCSE.

A tutorial ( part 1 &2) showing how to use Tikercad to create circuits and program with the Arduino Microcontroller. A fun introduction to programming can be used for Year 8 to 11 learners. Used to practise circuit bulding and programming before building their own circuits using leds, breadboard and Arduino connected via usb to their computer. Used with Year 9 to introduce electronics and programming. Lesson 1 : Controlling an led Lesson 2 : Creating a Traffic Light Simulation. Lesson 3 : Creating a strobe light effect - Knight Rider car Tinkercad is great simulation program , students learn quickly and then are much more confident at to being able to take the exported code and build their own circuits. Makes it much easier to manage a class of 25 Year 9s all doing practical.

An introduction to how css can be used internal css to change style in a single webpages to external css to apply to whole websites. Simple explanation with source code and a style switcher - A CV page to show -off tech skills containing a clock animation created using flash actionscript and an iPhone with scrollable screen and interactive buttons using Javascript to allow users to switch styles to plain print view styled page. Shows why Cascading Style sheets are so important. Another example to show how websites can allow users to switch between large and small text. Excellent visual way to explain why websites must allow the user to customise websites in terms of colours, size of text, background images etc, or risk discriminating / isolating users using Cascading Stylesheets. Can be used for all levels.
