What makes the simple hamburger bun the perfect stage for a juicy hamburger? An airy lightness? The sweet earthy taste and smell of yeasty dough? A hint of shiny brown sugars carmelized onto the surface of the bread in the baking or toasting process? White, wheat, potato? With or without sesame seeds? Or it is [...]
Video analysis is a powerful tool to help physics students understand motion and other phenomena. For example, in this video by Dale Basler (physics teacher and co-host of Lab Out Loud), students can analyze the speed and position time graph of the camera in a grocery store checkout line. Grocery Store Conveyor Belt Stops from [...]
Both may be guilty pleasures, but hamburgers and chocolate owe their status as mouth-watering treats thanks to chemistry. For hamburgers, it is that delicious brown, crusty surface that is left behind when the raw meat is exposed to high heat, something called the Maillard reaction. With chocolate, the substance falls in the literal sweet spot [...]
What makes nutmeg and cloves smell like Christmas, while polyurethane-based adhesive smells like, well, glue? As we enter week four of the weekly, online, video series “Chemistry Now,” we find that placement of a double bond in the hydrocarbon side chain makes all the difference in how eugenol, found in cloves, and isoeugenol, found in [...]
As part of the weekly, online, video series “Chemistry Now,” NSTA and NBC Learn have teamed up with the National Science Foundation (NSF) to create lessons related to common, physical objects in our world and the changes they undergo every day. The series also looks at the lives and work of scientists on the frontiers [...]
February’s Science 2.0 column focuses on how you can transform your classroom by using video lectures. Check out these videos by two of the pioneers of this approach: More videos on flipping your classroom are available here. Additional resources.
As we mentioned last week, NSTA and NBC Learn have teamed up with the National Science Foundation (NSF) to launch “Chemistry Now,” a weekly, online, video series that uncovers and explains the science of common, physical objects in our world and the changes they undergo every day. The series also looks at the lives and work [...]
In celebration of the International Year of Chemistry, NSTA and NBC Learn have teamed up with the National Science Foundation (NSF) to launch “Chemistry Now,” a weekly, online, video series that uncovers and explains the science of common, physical objects in our world and the changes they undergo every day. The series also looks at the [...]
As part of the quest to find relevant resources for SciLinks topics, I’ve been poking around YouTube, TeacherTube, and other video sites. I’ve certainly seen the good (which are considered for a SciLinks review), the bad (poor design or lots of errors), the ugly (talking-head lectures)—and the inappropriate. I really enjoy looking at the student-produced [...]
December’s Science 2.0 includes a brief example of how Dale Basler (physics teacher and co-host of Lab Out Loud) creates his own videos for use in his physics classroom. Here are a few examples: Bobber Meets Roundabout from Dale Basler on Vimeo. Grocery Store Conveyor Belt Stops from Dale Basler on Vimeo. See more here.
