Session 1 · THRIVE: Tune In

What drains us, what recharges us

  1. 10 minHook: show a phone battery icon at 12 per cent. How do you behave when your phone is this low? What about when you are this low?
  2. 15 minBattery audit (private): shade your own battery and list your drains and chargers from this week.
  3. 15 minClass 'drain or charge?' sort with anonymous examples: a late group chat, a walk with the dog, a fight with a sibling, footy practice, a quiet sit, a tournament weekend. Some go in both piles. Why?
  4. 10 minPose the big question and write three questions of your own about sleep, screens or stress. Post them anonymously on the class wonder wall.

Session 2 · THRIVE: Habits

Why do we get sleepy?

  1. 10 minRead the first half of 'Why you get sleepy'. Model sleep pressure: add one cube to a jar for every two hours awake, and empty it during sleep.
  2. 15 minBody clock walk: stand in a line from 6 am to midnight and act out what your body clock is doing (cortisol up in the morning, melatonin up in the evening).
  3. 15 minLearn the ruler-drop reaction test. Practise with a partner and agree on a fair method (same hand, same height, three tries, take the median).
  4. 10 minSet up your seven-night sleep and reaction log. Decide when you will do the ruler test each day.

Getting started

Use the picture battery and a word bank of drains and chargers if writing is a barrier.

Stretch

Predict what your reaction times will look like after short nights compared with long nights, and explain why using sleep pressure.

Checkpoint

Every student has a private battery audit and a sleep and reaction log ready to start.
