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 we find the volume of water saved?

  • September 9

Join faculty at St Philip's School and Community Center and talkSTEM on a math walk. They stop at the school garden and discuss how they can estimate the volume of water conserved? This video was supported by City of Dallas Office of Cultural Affairs.... CONTINUE READING

How does Gravity Affect Flowing Water?

  • September 9

Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor explores the natural phenomenon of water tapering in as it flows downward. Have you ever noticed this? A supplementary activity guide is available for this video, thanks to participation by faculty and students at Simmons School of Education and Human Development at SMU: https://talkstem.org/talkstem-activity-guid...

What Volume of Water can the Rain Barrels Hold?

  • September 9

At the Crystal Charity Ball Exploration Center at Camp Whispering Cedars, where Girl Scouts can marvel at plants growing on the building, you might notice from the video that the roof is sloped. Gravity pulls rainwater toward the front of the building, where the water falls into the gutters. From the gutters, the water is moved to plastic rain barrels, at the corners of the building. What an amazing example of sustainability and conservation efforts at work! We consider exactly how many toilet f... CONTINUE READING

How Big is the Pool?

  • September 9

Ever look into a pool and think, “Wow – that’s a lot of water!” This thought prompted us to consider exactly how many showers one could take using water in the pool at Camp Whispering Cedars. We started by measuring the surface area and perimeter of the pool before determining volume, using the formula, Volume=(Area)(Height). You’ll be amazed at what we discovered! Supplementary Activity Guides for this video to extend student learning for K-12 grade levels are freely available here:... CONTINUE READING
