Game Changers

This October, 4‑H launched 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!

National Youth Science Day

National Youth Science Day (NYSD) provides access and opportunity for kids to learn about STEM topics (science, technology, engineering and math) by participating in a hands-on STEM challenge. For the past 11 years, 4‑H has developed hands-on challenges that shows kids how STEM skills can be applied to the world around them.

NYSD is celebrated nationally on October 1st, with events taking place throughout the month of October and beyond in classrooms, clubs, homes and afterschool spaces across the country. Last fall, NYSD reached nearly 250,000 kids at thousands of events across all 50 states with the fun, hands-on challenge, Code Your World. Check out the 2018 NYSD how-to video to learn about Code Your World.

Watch this webinar to learn to code using Google CS First and Scratch (featuring activities from the 2019 NYSD challenge Game Changers).

In this webinar, we will explore Pitch Your Passion, the computer-based coding activity from the 2019 4‑H National Youth Science Day challenge, Game Changers.  Pitch Your Passion allows kids to animate a passion, issue, or cause they care about using code. The webinar will provide training on how to use both the Google CS First and Scratch platforms, instructions for online and offline use, as well as facilitator tips to put you on the path to success as you prepare for NYSD.

For the 2018 National Youth Science Day challenge, the WVU Extension Service 4‑H Youth Development Program distributed 400 Code Your World kits to WVU Extension faculty, school teachers, afterschool sites, and librarians across the state of West Virginia. With minimal training or additional resources, this initiative resulted in more than 7,000 state youth participating in one or more Code Your World activities between October and December. It also introduced new audiences to 4‑H and fostered new relationships between constituents and their county-based WVU Extension faculty members. In this webinar, Jen Robertson-Honecker (WVU Extension STEM Specialist) will discuss how WVU coordinated the state-wide distribution, the project’s resulting data, and how similar distributions could be replicated in other states.

Past Experiments

4‑H National Youth Science Day is the premier national rallying event for year-round 4‑H Science programming, bringing together youth, volunteers and educators from all over the country to simultaneously complete the National Science Experiment.

2018: Code Your World

Developed by Google and West Virginia University Extension Service, Code Your World includes a computer-based activity on Google’s CS First platform and three unplugged activities that bring coding to life through games and interaction.

2017: Incredible Wearables

Developed by the University of Nebraska – Lincoln, Incredible Wearables is a fun way for kids to build wearable fitness trackers.

2016: Drone Discovery

Drone Discovery was developed by Cornell University Cooperative Extension. It’s a hands-on engineering design challenge that explores the science behind drones and how they are being used to solve real world problems.

2015: Motion Commotion

Developed by Oregon State University Cooperative Extension, Motion Commotion is a two-part experiment that investigates the physical and human factors of motion using toy cars to simulate a speeding car collision and distracted driving.
