No Child Left Inside


On the Tuesday, October 14, you can make sure there’s “No Child Left Inside” (NCLI). Dedicate a day to outdoor activities enabling young people to experience the geosciences firsthand – during Earth Science Week or anytime throughout the year.

NCLI Day is celebrated on the Tuesday of each Earth Science Week, but any day can be NCLI Day! Young people everywhere enjoy experiences that make learning fresh and exciting. Your students will too. With the help of your colleagues, you can create an event that gets young people excited, shows the community what great things are happening at your school, and genuinely promotes high-quality, hands-on Earth science learning!

Plan your own NCLI Day event, where educators and young people can wade into ponds, climb hills, or search the skies to learn Earth science. Find the NCLI Day Guide, including the PDF version, at
