How can we estimate the amount of produce in a garden?

  • September 9

In order grow plants efficiently, making certain estimations is valuable - how well plants will grow, how much produce each plant will give use, or, even more fundamentally, how many plants we can fit in a given plot of land. Taking information we know about marigolds as an example, we showcase ways to determine these sorts of important predictions. This material is based upon work supported by the National Science Foundation under Grant DRL 2115393. Any opinions, findings, and conclusions or re... CONTINUE READING

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. Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily refle... CONTINUE READING

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

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.

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

How Tall is this Imaginary Person?

  • September 9

The sculpture Undulating X is constructed from metal in the shape of a giant chromosome, a discrete spool of DNA within a cell. But if a chromosome were actually this size, rather than microscopic, how big would the person who it belongs to be? Math can help us figure that out. Join talkSTEM and UT Southwestern faculty and grad students as they explore the STEM concepts on their campus.... CONTINUE READING
