How High Does it Climb?

  • September 9

The sculpture Venture, by Alexander Liberman, is composed of several steel tubes, stacked toward the sky. At such a great height, measuring its size by hand can be a challenge; instead visual estimation must be used. Additionally, the shapes comprising Venture are discussed, involving various ellipses and special forms that can even be recreated at home! This video was supported by the City of Dallas Office of Cultural Affairs. Supplementary Activity Guides for this video to extend student learn... 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 Can we Estimate Really Tall Things We Can’t Reach?

  • September 9

Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor, uses the mathematical properties of rectangles to help him measure the width of louvers that are extremely high us. 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/ Support for these guides w...

Why is There a Gap in the Building’s Facade?

  • September 9

This building has a unique design element – there is a gap in the facade of the building. Why would there be one? In this video, which is geared for high school students and older, Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor, discusses temperature changes that we are used to, here in Dallas. He goes on to explore the mathematical relationship between change in temperature and the expansion factor of aluminum. Supplementary Activity Guides fo... CONTINUE READING

How Did the Architects Play with Numbers?

  • September 9

Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor admires the unique grid up high above this space. Some questions that you get to explore are: What are louvers, and why are they useful?Can you identify other natural or man-made items which perform the same function or purpose as the louvers at the Winspear Opera House? What are the attributes of a quadrilateral, of a parallelogram? How could you measure the length of an object that is a far away fr... CONTINUE READING

What’s the Most Symmetrical Solid?

  • September 9

Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor speaks to us from Klyde Warren Park where he notices interesting things about the fun climbing structure in the Children’s playground and also the shape of the Perot Museum of Nature and Science in the distance. He makes connections between his observations and Platonic solids and also answers the question: What’s the Most Symmetrical Solid in the Dallas Arts District? Supplementary Activity Guid...
