Course Modules (8)

Module 1: Your Brain's Reward Button (15 min)

Deep inside your brain there is a tiny system that makes you feel good when you do something fun — scientists call it the reward system. This module explains how dopamine, a special brain chemical, gets released every time you see something exciting on a screen. Understanding this 'reward button' is the first step to becoming the boss of your own brain.

Dopamine is a chemical messenger in your brain that creates feelings of pleasure and excitement — it is released when you eat your favorite food, score a goal, or get a like on a post
Screens are designed to trigger tiny dopamine bursts over and over again, which is why scrolling through videos or playing games feels so rewarding even when you are not doing anything important
Your brain starts to crave more dopamine the more it gets, which means you may need longer screen sessions to feel the same level of fun — this is called building a tolerance
The reward system is not bad — it helps you learn and survive — but when screens hijack it, your brain can start ignoring other fun activities like playing outside or drawing

Module 2: Why One More Video Feels So Good (15 min)

Have you ever told yourself 'just one more video' and then realized an hour has gone by? This module explores the autoplay loop and why our brains find it so hard to stop when content keeps coming. You will learn what the 'curiosity gap' is and how it keeps you clicking.

Autoplay and 'Up Next' features remove the natural stopping point that would normally let your brain decide to do something else — the next video starts before you even think about it
Creators use cliffhangers, surprising thumbnails, and curiosity gaps on purpose to make your brain desperate to find out what happens next
Each new video gives your brain another small dopamine hit, creating a chain of rewards that feels impossible to break because your brain keeps expecting one more treat
Setting a specific number of videos or a timer before you start watching creates an external stopping point that helps your brain make the decision in advance

Module 3: The Tricks Apps Use to Keep You Watching (15 min)

Apps and games are built by teams of super-smart designers whose job is to keep you using their product as long as possible. This module pulls back the curtain on the most common design tricks — from infinite scroll to streaks — so you can spot them and not fall for them.

Infinite scroll removes the bottom of the page on purpose so there is never a natural place to stop — your thumb just keeps going and going like a hamster on a wheel
Streaks and daily rewards punish you for taking a break by threatening to reset your progress, which creates a fear of missing out even when you do not really want to play
Red notification badges are designed to look urgent and important, triggering a stress response that makes you feel like you MUST check them right away
Loot boxes and mystery rewards use variable reinforcement — the same trick used in slot machines — to keep you coming back because you never know when the next big prize will appear

Module 4: What Happens When You Can't Stop (15 min)

Sometimes screen use goes from being fun to being something you feel like you cannot control. This module gently explains what compulsive use looks like, why it happens, and reassures students that asking for help is brave and smart — not a sign of weakness.

Compulsive screen use means you keep using screens even when you do not really enjoy it anymore or when it is getting in the way of things you care about, like sleep, homework, or friendships
Warning signs include feeling anxious or angry when your device is taken away, hiding how much time you spend on screens, and losing interest in activities you used to love
This happens because your brain has gotten used to constant dopamine from screens and now other activities feel boring in comparison — but this can be reversed with practice
Talking to a trusted adult like a parent, teacher, or school counselor is one of the bravest and smartest things you can do if you feel like screens are controlling you instead of the other way around

Module 5: Screen Time and Your Mood (15 min)

Screens can change the way you feel — sometimes for the better and sometimes for the worse. This module explores the connection between screen time and emotions like happiness, sadness, anxiety, and boredom, helping students notice patterns in their own lives.

Research shows that kids and teens who spend more than two hours a day on recreational screens are more likely to report feeling unhappy, anxious, or lonely — though screens are not the only cause
Social media can create a 'comparison trap' where you compare your real life to other people's highlight reels, which can make you feel like you are not good enough even though those posts are not the whole truth
Screen use right before bed can make it harder to fall asleep and lower sleep quality, and poor sleep makes every emotion feel bigger and harder to handle the next day
Mindful screen use — choosing what you watch on purpose and checking in with your feelings — can help you enjoy screens without letting them drag your mood down

Module 6: Your Brain Is Not Broken (15 min)

This module is all about self-compassion. Many kids feel guilty or ashamed about how much time they spend on screens. Here we explain that the brain is working exactly as it should — it is the apps that are designed to exploit it — and that change is absolutely possible.

Your brain is doing exactly what brains are supposed to do — seeking out rewards and pleasure — so feeling drawn to screens is a sign that your brain is working perfectly, not that something is wrong with you
Billions of dollars and thousands of engineers go into making apps as addictive as possible, so struggling with screen time does not mean you are weak — it means the apps are very, very good at their job
Neuroplasticity means your brain can rewire itself at any age, which is great news because it means the habits you build now can change the way your brain works for the better
Being kind to yourself when you slip up is actually more effective than being hard on yourself — research shows that self-compassion helps people make lasting changes more than guilt does

Module 7: How Much Is Too Much? (15 min)

There is no single magic number for screen time because every person is different. This module helps students use the 'Screen Time Traffic Light' framework to figure out whether their screen use is in the green, yellow, or red zone based on how it affects their life.

Health experts suggest that children aged 6-12 aim for no more than one to two hours of recreational screen time per day, but the quality and type of content matters just as much as the quantity
Green Zone means screens are adding to your life — you are still sleeping well, doing your homework, spending time with friends, and enjoying offline hobbies
Yellow Zone means warning signs are appearing — you are staying up late because of screens, rushing through homework, or feeling irritable when asked to stop
Red Zone means screens are taking over — you are skipping activities you used to love, fighting with family about screen time, having trouble at school, or feeling like you cannot stop even when you want to

Module 8: Taking Back Control (15 min)

The final module brings everything together into an action plan. Students learn practical, age-appropriate strategies for managing screen time and commit to small, achievable changes they can start today.

The 'Pause and Plan' technique means taking three deep breaths before picking up your device and asking yourself 'What am I going to do, and for how long?' — this one habit can change everything
Setting up your environment for success includes charging your phone outside your bedroom, using app timers, and keeping fun offline activities visible and easy to reach
The 'Swap It' strategy means choosing one screen activity each day to replace with something offline you enjoy — you are not giving up fun, you are trading one kind of fun for another
Progress is not about being perfect — it is about making small improvements over time, celebrating your wins, and getting back on track when you slip up without beating yourself up
