Clouds are really incredible when you stop and think about them! So let's stop and think, and come up with a set of STEM questions all about them.... CONTINUE READING

What is Mathematical about a Tree? (version 2)

  • July 30

How do the size of branches in a tree change as you move up a tree trunk? And why do we see this change in size? Also, what does that have to do with the branch functions? Watch this video to see all trees in a different, and mathematical, way. Watch this video for a more detailed explanation on this question.... CONTINUE READING

What geometric patterns can we identify on a leaf?

  • September 9

A mathematical pattern is any sort of repeated property - something occurs frequently in nature! Taking a look at magnolias in particular, we identify branching patterns in leaf veins, and their degree of sub-level repetition. This allows us to understand various geometric concepts. This material is based upon work supported by the National Science Foundation under Grant DRL 2115393. Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author(s)... CONTINUE READING

How do you compare shapes?

What is this oversized sculpture? How can we use science to appreciate this art piece and math to understand more about it? Visit Dallas City Hall Plaza and explore "The Dallas Piece" for yourself. This video was supported by City of Dallas Office of Cultural Affairs.... CONTINUE READING

What are Fractals?

  • September 9

Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor, notices the beautiful, glossy leaves of the magnolia leaves that he walks by on this tour and call out the math pattern of the veins in the leaves. This fractal pattern, where the shape repeats itself but at a progressively smaller scale is common in nature and is a fascinating, relatively new field in mathematics.

How Can We Estimate the Amount of Water on Earth?

  • September 9

The terrazzo World Map in the main lobby provides a fairly accurate representation of the Earth’s surface. Using the lines separating its sections to divide it into quadrants, we can use fractions to estimate the portion of the whole covered by water. Combining these parts back together and comparing it to established numbers should give us and idea of how close we were able to get with our estimation!
