Lesson Activities by Day

Date	Phase 1: Starter (7 mins) Preparing the brain	Phase 2: Main (20 mins) New learning + assessment	Resources	Phase 3: Plenary (6 mins) Reflection + exercise
Mon 11 May 2026	1Learners will recall four common data threats and their basic definitions 2Display the image of a bank ATM on the projector and ask: What stops someone else from taking your money using your ATM card? Learners whisper answers to their partner, then select three pairs to share aloud (unauthorised access, password, card blocking)	FOUR DATA THREATS AND PROTECTION METHODS 1Using the projector and laptop, display a table with four columns: Unauthorised Access, Data Loss, Malware, and Eavesdropping. Read aloud one real scenario for each: (1) Ama's school account password is guessed by a classmate; (2) Kofi deletes his project file by accident; (3) Yakubu's phone is infected by a virus from a downloaded app; (4) Mensah's chat message is read by someone intercepting the network. Learners match each scenario to its threat by writing the threat name in their exercise books 2Introduce the four protection methods: Authentication (proving who you are with a password or fingerprint), Authorisation (giving permission to access certain files), Encryption (scrambling data so only the right person can read it), and Decryption (unscrambling encrypted data). Write each method on a flashcard and display on the board. Ask: Which method stops a stranger from guessing your password?—call on one boy and one girl to respond 3Struggling learners: provide a word bank with the four threats and four methods already listed; pair them with a stronger peer to match two examples together.	1Computer/Laptop 2Projector 3Internet connection 4Flashcards (Authentication, Authorisation, Encryption, Decryption) 5Exercise books	1Learners stand in pairs. Read one threat aloud (e.g. Eavesdropping). Each pair must call out the protection method that stops it within 5 seconds. Repeat for all four threats 2Ask: Show me with your fingers 1–4: which protection method is strongest against all threats?—learners respond (4 = Encryption). Confirm and praise Exercise 1Write in your exercise book: A student named Efua received a fake login page link via email asking for her school password. (1) Name the threat this represents. (2) Which protection method should Efua use to stay safe? Write one sentence explaining why
Wed 13 May 2026	1Learners will recall the four main data threats and identify their definitions from memory 2Show learners four cards with the words Malware, Phishing, Unauthorised Access, and Data Interception written on them. Ask: Which of these have you heard about before? Learners raise hands and give one-word answers (yes/no) for each threat	MATCHING DATA THREATS TO PROTECTION METHODS 1Display the four data threats (Malware, Phishing, Unauthorised Access, Data Interception) on the projector using the computer. Explain each threat in one sentence: Malware damages files; Phishing tricks users into giving passwords; Unauthorised Access lets people in without permission; Data Interception reads messages sent over the internet. Ask learners to copy the four threats and their meanings into their exercise books 2Write the four protection methods on the board: Authorisation, Authentication, Encryption, and Decryption. Read a real-world scenario aloud: Kwesi wants to access his online banking account to check his savings. Which protection method does the bank use to check that Kwesi is really Kwesi (password check)? Learners answer chorally: Authentication. Repeat with three more scenarios: Ama sends a secret exam timetable via email (use Encryption); Yaw's phone is stolen but his attacker cannot unlock it because they don't have his PIN (use Authentication); the school network blocks Adwoa from deleting teacher files because she is a student (use Authorisation). Use Computer/Laptop during the task 3Struggling learners: provide a completed matching sheet with three correct pairs already filled in; they complete the fourth pair. Fast finishers: create their own scenario for one protection method and present to their partner.	1Computer/Laptop 2Projector 3Internet connection 4Exercise books 5Marker and whiteboard	1Display a matching table on the projector with the four threats in column 1 and the four protection methods in column 2 (in random order). Learners copy the table and draw lines to match each threat to its correct protection method in their books 2Ask learners to hold up their matched tables. Invite one representative from each group to check their answers against the projector display. Learners thumbs-up if their table is correct Exercise 1Write one sentence: A student at Kejetia Senior High School receives an email asking him to enter his school portal password. Name the data threat and write the ONE protection method that would have stopped this attack in their exercise books.
