4-H Science

National Youth Science Day (NYSD)

4-H is dedicated to providing the hands-on experience in STEM (Science, Technology, Engineering, Math) to give kids the life skills they need to succeed today and the career readiness to succeed tomorrow. Programs like 4-H NYSD offer youth an opportunity to learn about science in a fun way and spark their interest in all areas of Science Engineering and Technology.    4-H National Youth Science Day started in 2008 and is a day dedicated to engaging kids with science through a hands-on science experiment and held annually on the Wednesday of National 4-H Week in October.

2019 National 4-H Youth Science Day Experiment - Game Changers

This October, 4‑H will launch the 2019 National Youth Science Day (NYSD) challenge, Game Changers. Designed by Google and West Virginia Extension service, Game Changers teaches kids ages 8-14 how to use computer science (CS) to create games, solve problems and engage with topics they’re passionate about.

Game Changers uses physical activity and puzzles to teach kids important CS concepts and problem-solving skills, creating real-world connections between computer science and civic engagement, healthy living and agriculture. Although the challenge includes one computer-based and two unplugged activities to help kids learn CS, all can be completed without internet access.

New to NYSD? Teachers and facilitators don’t need any prior experience with computer science or coding to bring Game Changers to their students. Get your Game Changers kit today!

2018 National 4-H Youth Science Day Experiment- Code Your World


Last October, 4‑H and Google launched, Code Your World, which invited youth to get involved in computer science.

Code Your World is a four-part computer science (CS) challenge that teaches kids to apply CS to the world around them through hands-on activities. Developed by Google and West Virginia University Extension Service, it includes a computer-based activity on Google’s CS First platform and three unplugged activities that bring coding to life through games and interaction.

Code Your World uses games and hands-on fun to teach kids important CS and computational thinking concepts, and is perfect for first-time and beginner coders ages 8-14.  Prior challenges are archived.
