How does the pendulum move?

  • September 9

A high school student at Hockaday School created a campus STEM walk for elementary students to enjoy. In this walk stop, she looks at the large pendulum the school is fortunate enough to have.... CONTINUE READING

How many tiles are there?

  • September 9

A high school student at Hockaday School created a campus STEM walk for elementary students to enjoy. In this walk stop, she comes up with a strategy for estimating the total number of tiles making up a walkway on campus.... CONTINUE READING

How tall is the Ad Astra sculpture?

  • September 9

Join Dr. Glen Whitney, founder of the National Museum of Mathematics on a math walk. He uses the power of similar triangles to calculate the height of a giant sculpture inside the NorthPark Center. How can we estimate the height of the sculpture without getting a ladder? 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:... CONTINUE READING

How is the artwork different from a water tower? – This Land Is Your Land

  • September 9

This video is part 1 of 3 visiting the artwork, This Land is Your Land in NorthPark Center. Artist reference the real world all the time when creating artwork. Can your brain determine the differences between a sculpture and the real object? Join Dr. Glen Whitney, Founder of the National Museum of Mathematics, as you discover how to determine the differences between artwork and objects in the real world. You can try this at home with any artwork! What differences do you see? This video was suppo... CONTINUE READING

How can a mirror help you play with symmetry?- This Land Is Your Land

  • September 9

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... CONTINUE READING

What is the golden ratio?

  • September 9

A high school student at Hockaday School created a campus STEM walk for elementary students to enjoy. In this walk stop she explores the golden ratio that she sees in the dance studio on campus.... CONTINUE READING

What’s the Mathematical Pattern?

  • September 9

The floor tiles used to make Untitled (Love Field) by Lane Banks only come in four colors, but never allow two rings of the same color to touch. With that in mind, methods of calculating how many permutations – specific, ordered arrangements – of these segments are possible are discussed. This uses the mathematical concept of factorials to practice combinatorics – the study of combinations and permutations. This video was supported by the City of Dallas Office of Cultural Affairs. Suppleme... CONTINUE READING

How tall is the sculpture?

  • September 9

A high school student at Hockaday School created a campus STEM walk for elementary students to enjoy. In this walk stop, she stops at a tall sculpture that contains glass shapes created by Hockaday students and invites us to estimate the height of the sculpture and also to estimate the total number of glass shapes on the sculpture using some math detective work!...

How does Gravity Affect Flowing Water?

  • September 9

Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor explores the natural phenomenon of water tapering in as it flows downward. Have you ever noticed this? A supplementary activity guide is available for this video, thanks to participation by faculty and students at Simmons School of Education and Human Development at SMU: https://talkstem.org/talkstem-activity-guid...

How Do We Measure Slope?

  • September 9

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
