This video is part 2 of 3 videos visiting the artwork, This Land is Your Land in NorthPark Center. Mirrors can create fun optical illusions if positioned in specific ways. Join Dr. Glen Whitney, Founder of the National Museum of Mathematics, as you discover how to use a mirror to play with symmetry, and see how the artist used this in This Land Is Your Land. This video was supported by NorthPark Center. Supplementary Activity Guides for this video to extend student learning for K-12 grade levels are freely available here: https://talkstem.org/talkstem-activity-guides/
