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 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
High school members of the Women in STEM club in Greenhill School stop at the playground on their math walk to share some math with the second graders. On the playground, we can see many different "tri-circles"! What is the easiest way to count how many of them there are? We try counting using different methods, such as counting in 2s, 3s, and 5s. This video content was contributed by community members from the Greenhill School - we invite all interested groups to reach out and find more informa... CONTINUE READING
High school members of the Women in STEM club in Greenhill School stop at the playground on their math walk to share some math with the second graders. There are angles all around us on our campus, including in the branches of the trees, and the walls of our buildings. How can we use our angle-a-tron tool to measure some of them? What can we learn about the different angles around us? You can freely print the shapefinder tool as well as the angle-a-tron tool onto an acetate using this pdf:... CONTINUE READING
High school members of the Women in STEM club in Greenhill School stop at the playground on their math walk to share some math with the second graders. What geometric shapes do we notice around Founders Place? How do the shapes affect the mood of the setting? How does math affect the way we feel?

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.

This video is part 3 of 3 videos visiting the artwork, This Land is Your Land in NorthPark Center. What is infinity? How did the artists create infinity for the viewer? Join Dr. Glen Whitney, Founder of the National Museum of Mathematics, as you discover how the artist created the sense of infinity in the piece, This Land Is Your Land, in NorthPark Center. Can you see other examples of infinity around you? This video was supported by NorthPark Center. Supplementary Activity Guides for this video... CONTINUE READING
