PADIKAM | CLASS 10 ICT - PART II Contents Four practical chapters use digital tools for science learning, animation, databases and free-software citizenship. Chapter 7 | Learning Science Through Computers Chapter 8 | Let's Give Life to Pictures Chapter 9 | To the Information Storehouse Chapter 10 | Software and Freedom How to use this book • Read the chapter mission first to understand the learning target. • Study the core notes and pause at every table, formula or process map. • Use the exam focus list for last-minute revision. • Answer the practice questions without looking back, then revise weak areas.

PADIKAM | CLASS 10 ICT - PART II CHAPTER 7 Learning Science Through Computers Chapter mission: use simulation and mathematical software to investigate scientific and geometric ideas. Simulation as a model • A simulation represents selected features of a real system. It allows safe, repeatable exploration but remains limited by assumptions. • Change one variable at a time, predict first, observe carefully and record evidence. • A visual result is not automatically proof; compare it with theory or real observations. Stellarium • Set observation location, date and time before selecting a celestial object. • Use search, time controls, coordinate grids and labels to study sky position and motion. • Changing location or date can model seasons, polar daylight and different sky views. GeoGebra and virtual labs • GeoGebra links construction, algebra, measurement and graphs dynamically. • Create free and dependent objects, drag permitted points and observe which relationships remain invariant. • A virtual lab supports hypothesis testing when real equipment is unavailable, but measurement uncertainty and real-world conditions still matter. Investigation record • Write question, prediction, controlled variables, procedure, observation and conclusion. • Capture screenshots only when they support a labelled explanation. • Save editable project files so the investigation can be repeated. Exam focus • State software settings that affect a result. • Distinguish model evidence from direct observation. • Describe an investigation as question-to-conclusion. Practice

1. How would you use Stellarium to study the midnight sun?
2. Design a GeoGebra test of a circle theorem.
3. State two advantages and one limitation of a virtual laboratory.

PADIKAM | CLASS 10 ICT - PART II CHAPTER 8 Let's Give Life to Pictures Chapter mission: plan and produce a short animation using frames, layers, timing and movement principles. Animation principles • Animation creates apparent movement from a sequence of still images. Frame rate controls how many frames display per second. • Key frames define important states; in-between frames create transition. • Timing, spacing, anticipation and follow-through make movement easier to understand and more natural. OpenToonz structure • A scene uses levels for artwork, columns/layers for separate elements and an Xsheet or timeline for frame timing. • Vector levels support scalable drawing; raster levels support pixel-based painting. • Keep background and moving objects separate to animate them independently. Production workflow • Write a short script and storyboard with shots, actions and duration. • Set project folders, canvas size and frame rate before detailed work. • Create/import assets, place key frames, add in-betweens or transformations, preview and refine timing. • Add audio only with permission, then render to the required video or image sequence format. Quality checks • Look for unwanted jumps, object-size changes, missing frames and elements leaving the camera area. • Save versions and preserve source assets. Credit reused media. Exam focus • Differentiate key frame, in-between and frame rate. • Explain columns/levels through independent control. • Include storyboard and preview in workflow answers. Practice

1. How does frame rate affect an animation?
2. Why should a moving cloud be on a separate level from the background?
3. Prepare a storyboard for a five-second science animation.

PADIKAM | CLASS 10 ICT - PART II CHAPTER 9 To the Information Storehouse Chapter mission: design a relational database and retrieve reliable information using forms and queries. Database concepts • A database stores organised related data. A table contains records (rows) and fields (columns). • A primary key uniquely identifies each record. A foreign key links a record to another table. • Good design reduces duplication and prevents inconsistent updates. Data types and validation • Choose types such as text, number, date or Boolean according to meaning, not appearance alone. • Validation rules, required fields and input formats reduce errors at entry. • A code or phone number may need text type when arithmetic is not meaningful. Forms, queries and reports • Forms simplify controlled data entry and viewing. • Queries filter, sort, calculate or combine data to answer a question. Criteria should be tested on known examples. • Reports format selected information for printing or sharing; they do not replace the underlying data. Responsible data handling • Collect only necessary data, restrict access and keep secure backups. • Personal data requires a lawful purpose, informed handling and appropriate retention. • Test database results for missing records, duplicates and incorrect relationships. Exam focus • Distinguish field, record, table and database. • Explain primary and foreign keys. • Write query criteria as a clear information question. Practice

1. Design tables for a school library database.
2. Why might a phone number be stored as text?
3. Describe a query to list overdue books by class.

PADIKAM | CLASS 10 ICT - PART II CHAPTER 10 Software and Freedom Chapter mission: understand software rights, free-software principles, licensing and responsible digital participation. Software and source code • Source code is human-readable program text; compiled or interpreted software turns instructions into executable behaviour. • Proprietary software generally restricts access or modification according to its licence. • Free software focuses on users' freedoms, not necessarily zero price. Four freedoms • Freedom to run a program for any purpose. • Freedom to study how it works and adapt it, which requires source-code access. • Freedom to redistribute copies. • Freedom to distribute modified versions so improvements can benefit others. Licences and communities • Copyright remains with creators; licences grant specified permissions. • Copyleft licences require derivative distributions to preserve defined freedoms; permissive licences usually impose fewer conditions. • Open collaboration uses version control, documentation, issue tracking, review and community rules. Open formats and digital independence • Open standards and formats reduce lock-in and improve long-term access and interoperability. • Schools and public institutions consider cost, localisation, transparency, security, support and accessibility when selecting software. • Respect every licence: freedom includes obligations such as attribution or sharing source when required. Exam focus • Explain free as freedom, not merely price. • State all four freedoms clearly. • Differentiate copyright, licence, open source and public domain. Practice

1. Why is source-code access necessary for studying software?
2. Compare copyleft and permissive licensing.
3. How can open formats support long-term public access?
