Understanding Explaining safe online habits in short sentences in ACARA Digital Technologies Years 5–6

What it does: The sentence has an action (log out on shared devices) and a reason after because. A clear explanation says what to do AND gives a reason using because. The word because links the habit to the reason for doing it. A short reason helps a younger student understand why the habit matters. The reason should explain how the habit keeps you safe. Because joins what you do to why you do it, so the habit makes sense. Add a reason: I lock my screen because other people could use my device. Start with the action: I use a unique passphrase because someone could get my account.

Common mistakes: The habit must be the safe action. 'I leave my screen unlocked' does not fit the reason that follows. It should be 'I lock my screen at school'. The reason after because must explain the online risk. Eating lunch has nothing to do with logging out. It should be 'use my account.'.

Spot the Error

Question 1
A I leave my screen unlocked
B because a classmate could
C read my private messages.
Line A — The habit must be the safe action. 'I leave my screen unlocked' does not fit the reason that follows. It should be 'I lock my screen at school'.
Question 2
A I log out on shared devices
B because someone else could
C eat my lunch at recess.
Line C — The reason after because must explain the online risk. Eating lunch has nothing to do with logging out. It should be 'use my account.'
Question 3
A I ask a trusted adult first
B if a message feels odd
C and they can help me.
Line C — The word 'and' does not give a reason. A clear safety sentence uses 'because', so it should be 'because they can help me.'
Question 4
A Poster checklist:
B 1. Say what to do.
C 2. Give a short reason.
D 3. Link it with maybe.
Line D — The word that links a habit to its reason is 'because'. 'Maybe' does not give a reason. It should be '3. Link it with because.'
Question 5
A Poster: Strong passphrases
B I use a long passphrase
C because a longer one is
D easier to guess.
Line D — The reason must be true. A longer passphrase is harder to guess, not easier. It should be 'harder to guess.'
