Coding + Fitness Safety Guide (Please read before starting the course) Course Description: This course combines computer science with physical wellness by teaching students how to design interactive fitness-themed games, tools, and challenges. Using Scratch’s video sensing, motion tracking, and other creative coding tools. Students will build games such as juggling simulators, soccer goalie challenges, reaction tests, and workout-timing utilities. Students will also explore additional software outside of Scratch to enhance their projects, learn basic video-based interaction techniques, and understand how different platforms interpret movement and input. By the end of the course, students will have created original “fitness hacks” that blend coding, creativity, and real-world physical activity. Safety & Setup for Video Sensing Activities Before we leap, stretch, jump, or flail in front of a webcam, students learn how to create a safe, functional, and non-chaotic workspace. Because motion projects involve actual movement, safety guidelines are essential for preventing accidents and for making sure the computer can read your movements accurately. Setting up a play area When testing motion-based games, students should stand more than an arm’s length away from their device. This minimizes the chances of you accidentally slapping your device, or one of your classmates. Students must also keep one open seat between themselves and classmates to allow safe movement. No elbow-to-elbow coding today. Chairs, backpacks, jackets, liquids, and the occasional forgotten snack wrapper should be moved aside to create a clean activity zone. Some activities may require a larger space such as a gym, yard, or park, and should only be done with counselor supervision. Always ask your counselor for approval before starting any motion activity! Lighting Requirements Rooms should be bright and evenly lit with steady lighting (no flickering lights). Think “cheerful learning space,” not “mysterious detective interrogation.” Avoid lighting directly behind a student because it turns them into a dramatic silhouette and the camera gets confused. Consistent lighting helps video sensing track movement accurately and prevents the tragic moment where Scratch thinks your hand is actually part of the wall. Device Placement & Stability Devices should be placed on a stable, unmoving surface such as a desk or table. Students should not hold their laptops during motion-based activities because shifts in angle or position interfere with camera tracking. If tablets or detachable devices are used, they should be secured using stands or cases that prevent wobbling. Camera Calibration Basics Students will practice adjusting their camera angle so they are framed correctly. If the camera can only see the top of your head or is aimed at the ceiling, it will not work correctly! Backlighting and strong shadows interfere with detection, so we avoid those. Students always test camera responsiveness before starting a project – a simple “wave test” works wonders. Behavior Expectations Students should move with energy but also with control, staying inside the interaction zone. No sprinting, no leaping off chairs, and definitely no “accidental” intruding in another student’s space. Respect for classmates’ space is essential so everyone stays safe. Communicating and Enforcing Safety rules To help students stay safe and get the best results from motion-based projects, teachers introduce and reinforce these rules consistently. Think of the rules like a gentle force field that blocks chaos and physical damage. 1. Show the included Safety Rules Poster Display the Coding + Fitness Quick Safety Rules poster at the front of the classroom or project it onto a screen before beginning any motion activity. Keep it visible throughout the lesson so students can reference it easily. 2. Review the Rules Together Read through each rule as a class. Teachers may invite volunteers to read aloud or summarize in their own words. This ensures all students understand the expectations. 3. Demonstrate Proper Setup Briefly model the key rules: • How far “one arm’s length” is • What a clear workspace looks like • How a device should be positioned • What gentle, controlled movement looks like A quick demonstration helps students visualize correct behavior. 4. Class Environment Check Have students inspect their own area and fix any issues such as clutter, poor lighting, or unstable devices. This builds responsibility and prepares them for safe movement. 5. Reinforce the “Why” Behind Each Rule Ask simple questions like: • “Why does the camera work better with bright light?” • “Why do we stand away from our device?” Students’ answers help them internalize the rules. 6. Maintain Consistency Before every motion-based project, briefly remind students of the rules and reference the poster. Praise students who follow expectations and calmly redirect those who forget. Time to Get Started! Now that students know how to move safely, set up their space, and keep their devices from falling off desks in dramatic slow motion, they’re ready to begin the fun stuff. Unit 1 introduces students to the basics of video sensing and shows them how to make their very first movement-powered interactions come to life. With safety mastered and creativity unlocked, it’s time to jump (gently and safely) into our first coding adventure! Let’s move on to UNIT 1! >>>
