Marcus's Tired Tuesday

The alarm clock buzzes. Marcus rolls over and slaps it. It is 7:00 a.m., and his eyes feel like they are full of sand.

Last night, Marcus stayed up way past his bedtime watching videos on his tablet. He didn't decide to stay up — he just kept tapping "next." Now his head hurts. His neck is stiff. He has 40 minutes before the school bus, and he doesn't want to move.

Has a morning like this ever happened to you? You stayed up too late on a screen, and the next day your whole body felt heavy and grumpy?

This chapter is the toolbox. It's full of small habits — for your eyes, your neck, your sleep, your time, and your home — that make screens feel good instead of awful. These habits aren't rules grown-ups made up to spoil your fun. They are tricks that real kids use to feel strong and stay in charge of their day.

Hi Again, Friends!

Hi friends, it's Maka! Last chapter we learned how to spot tech imbalance. This chapter is the toolbox we use to fix it. Pause, think, act — and pick one habit to try this week!

Mindful Use — The Big Idea

In Chapter 2 you learned about pause, think, act. When you do that with screens, it has a special name.

Mindful use is using a screen on purpose, with attention to how it makes you feel and how long you have been on it. The opposite is grabbing a screen because your hand is bored, then looking up an hour later and wondering what just happened.

When you use a screen mindfully, you ask three quick questions: Why am I picking this up? What do I want to do? When will I stop? Even a five-second pause for those questions changes the whole experience.

A whole bunch of small habits grow out of mindful use. We have a name for that bunch.

Healthy habits are the everyday choices you make that keep your body, brain, and mood in good shape. Eating breakfast is a healthy habit. Brushing your teeth is a healthy habit. The choices in this chapter are healthy habits for screens.

Habits for Your Body

Your body is the part of you that actually holds the screen. When you take care of it, screen time feels much better.

Posture is the way you hold your body when you sit, stand, or lie down. Good screen posture means sitting up straight, with the screen near eye level, your shoulders relaxed, and your feet on the floor. Bad screen posture is curling over a tablet on the couch with your neck bent like a question mark.

Try this right now. Notice how you are sitting. Are your shoulders pulled forward? Is your chin pointing at your knees? Sit up tall, roll your shoulders back, and take one slow breath. That tiny change is good posture.

Screen break is a short pause from a screen where you stand up, look away, and move your body. A great rhythm is five minutes off every twenty or thirty minutes on. A screen break is not a punishment. It is a reset that makes the next part of your screen time feel sharper and easier.

Blue light is the bright bluish light that screens shine into your eyes. Blue light can trick your brain into thinking it is still daytime, even when it is dark outside. That makes it harder to fall asleep at night.

Most tablets, phones, and laptops have a setting that turns the blue light down in the evening. Ask a trusted adult to help you turn it on. The screen will look a little warmer and more yellow after sunset — that is on purpose, and it helps your eyes wind down.

Sleep habits are the routines you follow at night to get a good rest. The most important screen-related sleep habit is simple: no screens in bed. Bright screens before sleep keep your brain busy when it wants to slow down. A good rule is to put screens away at least thirty minutes before bedtime.

Marcus's tired Tuesday happened because his sleep habits got crowded out by his screen time. He didn't choose to feel awful — he just forgot to put the tablet down.

Body habit	What to do	Why it helps
Posture	Sit tall, screen at eye level	Saves your neck and back
Screen break	Step away every 20–30 minutes	Rests your eyes and brain
Blue light	Turn on warm mode at night	Helps you fall asleep
Sleep habits	No screens in bed	Lets your brain wind down

Maka's Tip

Try the "tall otter" check. Once an hour, sit up as tall as a happy river otter on a log. Roll your shoulders back, look up at the ceiling for one slow breath, then look at something across the room. Your neck and your eyes will thank you.

Habits for Your Time

Taking care of your body is one half. Taking care of your time is the other half.

App time limit is a setting on a device that warns you — or stops an app — after you have used it for a certain number of minutes in a day. You and a trusted adult can set app time limits together. When the limit is reached, the app pauses and asks if you really want to keep going. That tiny pause is often enough to help you choose something else.

Digital habit tracker is a tool — sometimes a paper checklist, sometimes a small app — that helps you keep an eye on which screen habits you are doing each day. A simple digital habit tracker has rows like took screen breaks, no screens in bed, outdoor time, and tall otter check, with a box you can check off for each day of the week.

Daily tech log is a short list you write at the end of each day showing what you used screens for. Three lines is plenty: one for heart activities, one for brain activities, one for body activities. A daily tech log is not a report card. It is a way to notice what your screen day actually looked like, so you can choose differently tomorrow if you want.

Wellbeing check is a quick pause where you ask yourself two questions: How does my body feel right now? How does my mood feel right now? You can do a wellbeing check before you pick up a screen, in the middle of using one, or after you put it down. It only takes a few seconds.

If your wellbeing check turns up something that really worries you — eyes that hurt all day, a mood that feels stuck and sad, sleep that won't come — tell a trusted adult. They will help you figure out what to change. You will not be in trouble for telling.

MicroSim: The Digital Habit Tracker

Digital Habit Tracker — interactive p5.js MicroSim

Type: microsim sim-id: digital-habit-tracker
Library: p5.js
Status: Specified

Learning objective (Bloom: Apply): Given a week's worth of healthy screen habits, the student can check off the ones they have done each day and see a simple weekly score.

Visual elements:

A responsive canvas (default 720 × 480, resizes with container width via updateCanvasSize() called first in setup()).
A grid of habits down the left side, with seven day columns (Mon–Sun) across the top. Each cell is a clickable checkbox.
Default habits: Took screen breaks, No screens in bed, Tall otter posture, Outdoor time, Wellbeing check, Family meal with no screens.
A score panel on the right that updates as the student checks off boxes, showing how many habits they hit out of the weekly total.
A friendly message area below the grid that gives a one-sentence encouragement at 50%, 75%, and 100% complete.

Controls (built-in p5.js controls per project rules, placed at the bottom of the canvas):

createButton('Reset week') to clear all checkboxes and start over.
createButton('Add habit') and createInput() so the student can type in one habit of their own.
createSelect() to switch between three view modes: This week, Last week, Since I started.

Behavior:

Clicking any cell toggles it between empty and checked.
The score panel updates immediately on every click.
The state is held in memory for the session — no database, no login.
All language is encouraging, never shaming. A low score gets a kind "tomorrow is a fresh row" message, never a sad face.

Implementation notes:

File location: docs/sims/digital-habit-tracker/ with main.html, main.js, and index.md.
main.html uses a plain <main></main> tag with no id attribute, so teachers can copy main.js directly into the p5.js editor.
In setup(), call updateCanvasSize() first, then canvas.parent(document.querySelector('main')).
Embedded into the chapter via an iframe in the chapter page once the sim files are built. The actual sim files are not part of this chapter task — only the spec lives here.

Implementation: p5.js sketch deployed at docs/sims/digital-habit-tracker/.

Habits for Your Whole Life

Screens are part of life, but they are not all of life. The next set of habits protects the not-screen parts of your day.

Offline activity is anything you do that does not need a screen at all. Reading a paper book, drawing on real paper, building with blocks, baking cookies, playing a board game with your sister — those are all offline activities. They use the same parts of your brain that screens use, but they leave your eyes alone.

Outdoor time is exactly what it sounds like — time spent outside, in real sunlight, breathing real air. Outdoor time is one of the most powerful habits there is. Sunlight helps you sleep better at night. Movement outside lifts your mood. Even ten or fifteen minutes outside can turn a tired tech day around.

Tech-free zone is a place in your home where screens are not allowed at all. Many families pick the dinner table as a tech-free zone, so meals stay for talking and eating. Some families pick bedrooms as tech-free zones, so sleep stays protected. A tech-free zone makes a rule easy, because everyone agrees on it before anybody is tempted.

The biggest habit of all puts the whole chapter together.

Family media plan is a written agreement between you and the grown-ups in your home about how everyone in the family will use screens. A family media plan answers questions like: Where are our tech-free zones? What time do all screens go away at night? How long can we play games or watch videos each day? When do we eat without screens?

A family media plan is not the grown-ups bossing you. The whole point is that everyone in the family — kids and grown-ups — helps make it. Then everyone follows it together. If the plan needs to change, you can sit back down and change it together.

A great family media plan usually includes:

A bedtime when all screens go away (the same time for kids and grown-ups)
A list of tech-free zones in your home
Daily limits for games and videos
A few protected offline times — meals, family game night, outdoor time
A weekly wellbeing check the whole family does together

A Big Idea

The best rules are the ones you help make. When you help write your family media plan, it stops feeling like a rule and starts feeling like a promise you made to your future self. Pause, think, act!

Marcus's Wednesday Reset

It is Wednesday morning. Last night, Marcus and his mom and his big sister sat at the kitchen table and wrote a simple family media plan together. The kitchen table is now a tech-free zone. All screens go on the charging shelf at 8:30 p.m. Marcus helped pick every rule, and all three of them signed the bottom of the page.

Marcus slept the whole night through. He wakes up before the alarm. He stretches and feels his neck — no stiff spot, no headache. He hops out of bed and grins.

You can build your own healthy tech habits, one small step at a time. You don't have to do all fourteen at once. Pick one. Try it for a week. Then add another.
