Code Your World

This October, 4‑H and Google will launch an exciting National Youth Science Day challenge, Code Your World, which invites kids to get involved in computer science through hands-on doing.

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.

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 ten years, 4‑H has developed hands-on challenges that shows kids how STEM skills can be applied to the world around them. This fall, we expect to reach more than 150,000 kids at thousands of events across all 50 states through NYSD.

4‑H will hold NYSD events throughout the month of October in classrooms, clubs, homes and after-school spaces across the country. Check out a preview of this year’s Code Your World challenge and find out how you can get involved!

NYSD 2017 Event Map

On October 4, 2017, thousands of youth from 4‑H clubs, groups and school programs across the country participated in Incredible Wearables, the 4‑H NYSD 2017 Engineering Design Challenge. Each pinpoint on the map represents a 2017 Incredible Wearables event.

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.

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.

2014: Rockets to the Rescue

The University of Arizona developed Rockets to the Rescue, which explores the field of aerospace engineering. Youth learn engineering concepts, develop math skills, learn about nutrition and help solve a relevant, global issue.

2013: 4‑H Maps & Apps

With 4‑H Maps & Apps, young people become geospatial thinkers as they design and map their ideal park, use GIS mapping to solve community problems and contribute data about their community to the United States Geological Survey (USGS).

2012: Eco-Bot Challenge

In the 4‑H Eco-Bot Challenge, youth test the interaction between the Eco-Bot’s environmental engineering design features and various control surface configurations to determine the most effective environmental clean-up solution for a simulated toxic spill.

2011: Wired for Wind

Wired for Wind explores how to engineer renewable energy technologies and the positive impact that they can have in communities across the country and the world.

2010: 4‑H2O

4‑H2O is designed to engage youth in asking the question: Why is water quality important and why is it important to understand it now?

2009: Biofuel Blast

Biofuel Blast explores the production of the biofuel ethanol.

2008: Helpful Hydrogels

In Helpful Hydrogels, youth explore a new superabsorbent polymer – called hydrogel – that can help with water conservation right in our own backyards.
