How many tiles are there?

  • September 9

A high school student at Hockaday School created a campus STEM walk for elementary students to enjoy. In this walk stop, she comes up with a strategy for estimating the total number of tiles making up a walkway on campus.... CONTINUE READING

How many sections are there?

  • September 9

A high school student at Hockaday School created a campus STEM walk for elementary students to enjoy. In this walk stop, she looks at the beautifully statue of Hypatia, an ancient Egyptian mathematician and astronomer who died 415 AD. Here she notices the circle surrounding the sections and asks us to do some math to figure out the number of sections within this circle.... CONTINUE READING

How tall is the sculpture?

  • September 9

A high school student at Hockaday School created a campus STEM walk for elementary students to enjoy. In this walk stop, she stops at a tall sculpture that contains glass shapes created by Hockaday students and invites us to estimate the height of the sculpture and also to estimate the total number of glass shapes on the sculpture using some math detective work!...

How do Scientists use Observations?

  • September 9

Science is a collaborative effort, bringing together observations from many different times, places, and observers. The many eyes on display in the UT Southwestern Medical Center echo this, something we discuss! Join talkSTEM and UT Southwestern faculty and graduate students as they explore the STEM concepts on their campus.... CONTINUE READING

Where Can We See Symmetry in this Airplane?

  • September 9

The Tuskegee Airmen were the first Black military aviators in the U.S. Army Air Corps, a precursor of the U.S. Air Force. They flew more than 15,000 individual sorties in Europe and North Africa during World War II. Their performance earned them more than 150 Distinguished Flying Crosses, and helped encourage the eventual integration of the U.S. armed forces. In this video we explore the symmetries we can observe as we explore a model of the airplane these heroes flew. Supplementary Activity Gui... CONTINUE READING

What Does it Mean to “Circumnavigate”?

  • September 9

Amelia Earhart was an American aviator who mysteriously disappeared in 1937 while trying to circumnavigate the globe from the equator. Earhart was the 16th woman to be issued a pilot’s license. She had several notable flights, including becoming the first woman to fly across the Atlantic Ocean in 1928, as well as the first person to fly over both the Atlantic and Pacific. Here, we explore what is meant, mathematically, by the term “circumnavigation.” Supplementary Activity Guides to extend... CONTINUE READING
