What determines the shape of a waterfall? And how we use talkSTEM resources to figure it out?... CONTINUE READING

Why these colors?

  • July 30

The oranges, blues, and greens of the Region 10 ESC logo show up a lot in this building, from floors to chairs to posters - but why were these colors chosen? How do designers use a color scheme to create an intentional effect? How is a color wheel a type of math or scientific model? And how do distances from each other on color wheels help in design?...

How does Gravity Affect Flowing Water? (version 2)

  • July 30

Why does the width of water in the fountain, or even from a kitchen faucet, get narrower as it falls. Watch this video to see this phenomenon and to consider this question. For a more detailed look at this same phenomenon at the same fountain, watch this video too.... 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 is the weight of an ice rink?

  • September 9

Ronald Kirk Bridge is a pedestrian bridge over the Trinity River in Dallas, connecting downtown Dallas and West Dallas. It is over 2,000 feet long and 60 feet wide. What would happen if water froze on the middle of the Ron Kirk Bridge? Could we create an ice rink on this bridge? talkSTEM members explore this question and estimate how much weight an ice rink would add to the bridge.... CONTINUE READING

How do we find the volume of water saved?

  • September 9

Join faculty at St Philip's School and Community Center and talkSTEM on a math walk. They stop at the school garden and discuss how they can estimate the volume of water conserved? This video was supported by City of Dallas Office of Cultural Affairs.... CONTINUE READING
