Are your students tired? Do they struggle with morning fatigue, yet stay glued to their screens late into the night? It’s the paradox of modern adolescence. This comprehensive, project-based learning (PBL) module transforms their struggle into a powerful scientific investigation.

Turn Students into Scientists with This Hands-On Health Project!

Instead of just telling students that “screens are bad for sleep,” this resource empowers them to prove it to themselves. “The Screen Time & Sleep Experiment” is a rigorous, 4-week unit that guides students through an N-of-1 trial—a personal experiment where they are both the researcher and the subject!

Students will learn the deep neurobiology behind sleep (melatonin, suprachiasmatic nucleus, ipRGCs) and then apply it by tracking their own data. They will use detailed logs to correlate evening screen time with critical metrics like Sleep Onset Latency (SOL) and Morning Energy Levels. This isn’t just a worksheet; it’s a journey of self-discovery that builds critical life skills.

What’s Included in This 36-Page Turnkey Resource?

Part 1: The Empirical Approach to Sleep Hygiene (11 Pages): A detailed, student-facing guide explaining the science of circadian rhythms, melatonin suppression, photic vs. cognitive arousal, and intervention strategies.
Part 2: Student Workbook (16 Pages): Features 10 detailed worksheets that guide students through every phase of their experiment—from establishing a baseline to tracking interventions (software filters, blue-light glasses), analyzing data, and creating a sustainable personal sleep protocol.
Part 3: Visuals & Teacher Resources (9 Pages): Everything you need to facilitate the project with confidence. This section includes:
High-resolution conceptual diagrams (flowcharts, scatter plots).
A comprehensive, fill-in-the-blank Answer Key.
A detailed Teacher Implementation Guide with a 4-week pacing plan, advice on navigating subjective data, and strategies for ensuring student privacy.
Why This Project is a Game-Changer for Your Classroom:

Relevant & Engaging: Tackles a real-world issue that directly impacts every student’s daily life, health, and academic performance.
Promotes Scientific Literacy: Students practice the scientific method, collect and analyze quantitative data, identify confounding variables, and distinguish correlation from causation.
Cross-Curricular: Perfect for Health, Biology, AP Psychology, Human Anatomy & Physiology, and even Statistics classes.
Builds Digital Citizenship & SEL: Encourages self-regulation, mindfulness about technology use, and empowers students to take control of their own well-being.
Give your students the “aha!” moment they need to understand the invisible mechanics of their own biology. Equip them with the knowledge and skills to navigate the digital age in a healthy, productive way. Download this print-and-go resource today!
