A high school student at Hockaday School created a campus STEM walk for elementary students to enjoy. In this walk stop, she invites us to consider the slope of the outdoor amphitheater on the campus.... CONTINUE READING
Airports can be bustling places, filled with thousands of people all trying to get to where they need to go all at once. Interior designers can help direct this flow by emphasizing intuitive wayfinding in their work – subtle clues and markers incorporated in a space's design that make navigation easier to naturally understand. In Love Field, this involves patterns in the tiles and ceilings that help guide travelers to where they need to go. This video was supported by the City of Dallas Office... CONTINUE READING
Slope is a way of describing the way that a line or plane – like a sidewalk – changes over a distance. Using these principles, we describe the way the grounds around us were built. Join talkSTEM and UT Southwestern faculty and grad students as they explore the STEM concepts on their campus.... CONTINUE READING
Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor wonders what is the slope of the amphitheater and figures out a quick way to estimate it.... CONTINUE READING
We explore how to use slope, the ratio of height to horizontal distance, to better understand how stairs are designed based on international building codes to keep us safe. 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/ We invite all interested groups to reach out and find more informat...

Scouts love visiting Camp Whispering Cedars for its amazing ropes course – great for bonding and pushing new boundaries! The course features a zip line, ropes bridge, climbing wall, and a towering three-person swing. The swing made us wonder – exactly how high is someone pulled to start the swing? In order to figure this out, we use shadows and similar triangles. Supplementary Activity Guides for this video to extend student learning for K-12 grade levels are freely available here:...
