Which mass travels faster?

  • 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, 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

How many “tri-circles” are there in the playground?

  • September 9

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

How many angles can you find using the angle-a-tron?

  • September 9

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

What shapes bring us together?

  • September 9

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?

Why is the school building designed the way it is?

  • September 9

Join these scholars from Dallas Independent School District Solar Preparatory School for Girls as they lead us on a walkSTEM tour of their campus. They address such questions as why one window is a lot larger than the other at opposite ends of a hallway, how a map relates to math and science, why one room has more of an echo than another, and more! This content was made by community members from Solar Prep School for Girls. We invite all interested groups to reach out and find more information o... CONTINUE READING

How Can Shapes Create Feelings?

  • September 9

Architect I. M. Pei designed this visually striking building. Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor, points out that the effect of the design is dependent in part on the use of two geometric shapes that are unexpectedly used together.

How Do Cylinders Make Beautiful Shapes?

  • September 9

Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor, is struck by the cylinders obvious in the design of this modern building. The building is formed from two cylinders that intersect to form a beautiful parabola.
