Data ethics and privacy are the focus of this Grade 10 Computer Science worksheet for a Data and Information lesson. Students examine how personal information should be collected, stored, shared, and used while applying ideas such as informed consent, transparency, purpose limitation, anonymization, pseudonymization, security controls, and re-identification risk.

Move from Privacy Vocabulary to Ethical Decisions

Students consider why people should receive clear explanations before personal information is collected and how informed consent supports responsible data use. They also explore purpose limitation: data collected for one stated reason should not automatically be reused for unrelated goals.

The lesson connects these principles with realistic privacy risks. Students analyze situations involving detailed location information, sensitive records, and data sharing, then determine which risks should be checked before information is released or reused.

Anonymization Is Not the End of the Privacy Check

A key concept is re-identification risk. Students examine why removing names does not necessarily guarantee that a person cannot be identified when detailed information can be linked with other datasets. They differentiate anonymization from pseudonymization and consider why privacy protections require careful evaluation rather than relying on a single technique.

Security measures are also connected to ethical data handling. The reading and questions address encryption, strong authentication, and access limits as safeguards that help prevent unauthorized viewing or modification of stored information.

How Students Apply the Concepts

• A dialogue-based question introduces responsible data-use decisions
• A matching activity connects privacy and data-ethics concepts
• A cloze passage reviews consent, purpose, privacy risks, anonymization, and safeguards
• A diagram-labeling activity reinforces key ideas visually
• An informational reading passage explains consent, transparency, re-identification, security controls, and purpose limitation
• Multiple-choice questions ask students to evaluate ethical collection, sharing, and privacy practices
• True-or-false statements address misconceptions about consent, anonymization, security, and purpose limitation
• Short-answer prompts require students to explain privacy protections and security controls
• An extended response asks students to develop an ethical plan for collecting and sharing student app data

Teacher Support for Discussion and Application

A separate Teacher Guide PDF includes learning objectives, teaching tips, discussion questions, and common mistakes. The resource can support direct instruction, guided discussion, independent practice, homework, or review while helping students apply ethical principles to personal and sensitive data scenarios.
