How tall are the gateway arches?

  • September 9

West End Historic District is marked by these beautiful brick arches and we wonder what is the tallest person that could walk under them? We used math to figure that out. This video was supported by City of Dallas Office of Cultural Affairs.... CONTINUE READING

How can we measure arches and lines?

  • September 9

Over 7 million people visit the West End Historic District every year! What if they all stood in line to visit? What would that look like? We use math to help us understand this gargantuan number! This video was supported by City of Dallas Office of Cultural Affairs.... CONTINUE READING

What is the speed of the water?

  • September 9

Ronald Kirk Bridge is a pedestrian bridge over the Trinity River in Dallas, connecting downtown Dallas and West Dallas. It is over 2,000 feet long and 60 feet wide. At the Ronald Kirk Bridge, the talkSTEM team found a natural whirlpool in the Trinity River. The video explores a strategy for estimating the speed of water. What other strategies could you use to measure the speed of a liquid? What about objects traveling through air instead of water? At talkSTEM, we know that math isn't always perf... CONTINUE READING

What is a trapezoid?

  • September 9

Join us on a math walk where we look for geometric shapes at Dallas City Hall. The building reminds us of a triangle embedded in the ground. The result looks like a trapezoid. What is a trapezoid? What other shapes can you recognize in this building? How can we measure the angle made by the building? This video was supported by City of Dallas Office of Cultural Affairs.... CONTINUE READING

What is the weight of an ice rink?

  • September 9

Ronald Kirk Bridge is a pedestrian bridge over the Trinity River in Dallas, connecting downtown Dallas and West Dallas. It is over 2,000 feet long and 60 feet wide. What would happen if water froze on the middle of the Ron Kirk Bridge? Could we create an ice rink on this bridge? talkSTEM members explore this question and estimate how much weight an ice rink would add to the bridge.... CONTINUE READING

How do you compare shapes?

  • September 9

What is this oversized sculpture? How can we use science to appreciate this art piece and math to understand more about it? Visit Dallas City Hall Plaza and explore "The Dallas Piece" for yourself. This video was supported by City of Dallas Office of Cultural Affairs.... CONTINUE READING

What is a dodecahedron?

  • September 9

Ronald Kirk Bridge is a pedestrian bridge over the Trinity River in Dallas, connecting downtown Dallas and West Dallas. It is over 2,000 feet long and 60 feet wide. At Ronald Kirk Bridge there is a great climbing structure at their playground. We noticed something interesting about the shape of the climbing structure. What exactly is that repeated shape on the playground, and why did they use that one instead of a cube or sphere? It's your turn! If you designed your own playground, what shape cl... CONTINUE READING
