Where do the straight lines of a turtle’s scutes come from?
- July 30
It can feel unusual to see straight lines in nature, which makes the scutes of a turtle's shell really stand out! Join us as we try to piece together why they look the way they do.... CONTINUE READING
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

What is the speed of the water?
- 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. At the Ronald Kirk Bridge, the talkSTEM team found a natural whirlpool in the Trinity River. The video explores a strategy for estimating the speed of water. What other strategies could you use to measure the speed of a liquid? What about objects traveling through air instead of water? At talkSTEM, we know that math isn't always perf... CONTINUE READING
