Plastic pollution is a problem, especially in our oceans. National Geographic Explorer Heather Koldewey, along with a team of experts, set off on an expedition to find answers.

From the Education Resource Library! Travel along with Alex Tait, The Geographer at National Geographic, and a team of mappers on an expedition to Mount Everest. They scan using LiDAR and perform detailed photogrammetry of the entire Khumbu glacier from the South Col all the way down to the toe of the glacier and all of Everest Base Camp—at the highest resolution ever collected at Mount Everest. The maps produced from the data will help scientists better understand the dynamics of the ice and snow on the mountain and how the warming climate is impacting the region. Here are some activities for your students: K-5: Draw a picture or photo strip of something you learned. Grades 5-8: Write a short “news article” about what you learned. High School: Produce a short video that explains something you learned today. Share your students activities by @NatGeoEducation and using #ExplorerClassroom on Twitter. Our team will share your student work with the Explorer. We invite you to explore collections of activities that have been developed for educators, parents, and caregivers to implement with K-12 learners. https://www.nationalgeographic.org/education/classroom-resources/learn-at-home/ WHAT IS THE RESOURCE LIBRARY The National Geographic Resource Library provides online materials that take students on thought-provoking journeys, engaging them with entertaining stories and rich photography.
