Why is There a Gap in the Building’s Facade?

  • September 9

This building has a unique design element – there is a gap in the facade of the building. Why would there be one? In this video, which is geared for high school students and older, Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor, discusses temperature changes that we are used to, here in Dallas. He goes on to explore the mathematical relationship between change in temperature and the expansion factor of aluminum. Supplementary Activity Guides fo... 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 is Mathematical about a Tree?

  • September 9

Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor wonders what is mathematical about trees. He asks why do trees always have a larger singular trunk at the Earth, and more smaller branches in the sky? Why not one singular branch that stretches up? Dr. Glen Whitney explores this natural phenomenon that applies to all trees. A supplementary activity guide is available for this video, thanks to participation by faculty and students at Simmons School of... CONTINUE READING

How Many People Fit on a 737 Plane?

  • September 9

We wonder what the maximum number of people is that could fit on board the 737 people we are walking through at the museum? How can we come up with a good estimate? We use number arrays to come up with our estimate and walk you through our thinking.

Why is it Called the Flying Pancake?

  • September 9

The Flying Pancake is a fun name for a unique airplane that is no longer in use. We wonder as to why this aircraft was designed to have a flat wing-like body giving it such a large surface area? We explore this unique design and come to understand how this design met its goals but also came at a cost.

Why is the Apollo VII shaped that way?

  • September 9

The Command Module of the Apollo VII mission has a truncated cone shape which was essential to its goals of leaving the earth's atmosphere and then safely re-entering the atmosphere to bring its crew back to Earth in 1968. Here, we wonder how the shape of the module was an important aspect of its design and learn about cone shapes, air resistance, and surface area.

What Materials Make Up the Apollo VII?

  • September 9

We notice that the bottom surface of the Command Module of the Apollo VII space mission looks different from the material making up the rest of the module. We learn that this difference is a critical part of the design of the module that brought home the crew of 3 astronauts in 1968. Further, the heat shield material that was developed for the command module’s bottom surface is now something we use in everyday life – great example of innovation that ends up being used far more widely than an...

What’s My Question – Estimation, Quantity, and Scale

  • September 9

Estimation, quantity, and scale help us understand aspects of the world around us that we can’t always interact with directly – these tools help us understand large objects and numbers, and ways to represent them. We discuss the questions students at the St. Philip’s School and Community Center posed within this math theme to show just how intuitive this can be! This material is based upon work supported by the National Science Foundation under Grant DRL 2115393. Any opinions, findings, an... CONTINUE READING

How Many People Can Fit on the Observation Deck?

  • September 9

At Camp Whispering Cedars, Girl Scouts climb a winding series of steps to reach the top of an observation deck, where they can stargaze or have meetings. We wonder how they might estimate exactly how many people could have fun stargazing sleepover party on the deck!

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!
