Marta Pan's kinetic artwork, Floating Sculpture, is the subject of our STEM lens. What mathematical questions did Marta inspire when she created this work? Let's explore! This video was supported by City of Dallas Office of Cultural Affairs.... CONTINUE READING
Towering over Dallas City Hall Plaza are 3 flag poles. How do we use similar triangles and shadows to determine their height? This video was supported by City of Dallas Office of Cultural Affairs.... CONTINUE READING
What's the best way to figure out the number of windows on the Texas School Book Depository? Math, of course! Watch the video to see how we applied the concept of arrays to answer this question. This video was supported by City of Dallas Office of Cultural Affairs.... CONTINUE READING
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
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
talkSTEM uses estimation, geometry, and their knowledge of volume to figure out how much water is in the Dealey Plaza fountains. This video was supported by City of Dallas Office of Cultural Affairs.... CONTINUE READING
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
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
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...

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, talkSTEM members, Michael and Mary, did an experiment to see which would travel down the Trinity River the fastest - the thicker or thinner stick. Make your hypothesis - would heavier or lighter mass travel faster? Watch the video to find out!... CONTINUE READING
