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.

Recipe Ratios: Which recipe uses more chiles?

  • September 9

When using recipes, determining how much of each ingredient is needed is an important task - particularly if you're making an amount different than what the recipe directly instructs! By looking at two different recipes for salsa, and using ratios and unit conversions to make them more easily comparable, we can begin to determine how much of these wonderful garden ingredients we'd need to use for each dish. This material is based upon work supported by the National Science Foundation under Grant... CONTINUE READING

What’s the Scale Factor used in the Blueprint for the Welcome Center?

  • September 9

Students from St. Philip's School & Community Center on a math walk stop at the newly constructed Welcome Center at their school. They wonder what the scale factor was that was used to build the space as the builders went from blueprint to real space? This material is based upon work supported by the National Science Foundation under Grant DRL 2115393.

How many students fit in the chapel while observing social distancing regulations?

  • September 9

Students from St. Philip's School & Community Center on a math walk stop at the school chapel. They wonder what the maximum number of people is that could fit in this space given social distancing protocols during the Covid pandemic? They use the patterns on the carpet, and some simple estimation strategies to answer their question. This material is based upon work supported by the National Science Foundation under Grant DRL 2115393. Any opinions, findings, and conclusions or recommendations... CONTINUE READING

How can a mirror help you play with symmetry?- This Land Is Your Land

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.

What’s the Scale?

  • September 9

The giant mosaic North Texas Sunrise depicts many native texan flowers, all far larger than life. Using a standard 8.5" x 11" sheet paper as a measuring device, we calculate how much larger the mosaic flowers are than the real thing, determining the scale of the artwork.
