I’ve written about incentivizing students as a way towards engagement. I recently hit upon a great idea — a real brain wave. AP Chemistry students completed a challenging lab where they carried out (and analyzed) a bunch of redox reactions. Afterwards, we had a discussion, which included repeating several of the reactions as teacher demonstrations, with … Continue reading
Introduction Hans Christian Oersted (1777–1851), a Danish physicist, was performing an experiment in 1820 when he noticed that whenever an electric current from a battery was switched on or off, a nearby compass needle was deflected. Through additional experiments, Oersted was able to demonstrate the link between electricity and magnetism. The following year, English scientist Michael Faraday … Continue reading
Remind allows teachers to send messages to students and parents regarding upcoming assignments, meetings, events, and activities. This application also permits teachers to check which students have read their messages. Messages can be sent to individuals, to a group, or to a class. Remind is safe since phone numbers, which can be used to invite members, are kept … Continue reading
As most investigations do, this one began with a question. I had a log delivery to my house. The logs were primarily birch. What caused the damage to the birch trees that I was chopping up for wood? The holes were too shallow to suspect woodpeckers. I peeled off the bark, fully expecting to see … Continue reading
Retired astronaut Chris Hadfield helps debunk (and confirm!) some common myths about space. Is there any sound in space? Does space smell like burnt steak? Is NASA working on warp speed? ONE STRANGE ROCK airs Mondays at 10/9c on National Geographic.
From the smallest single-celled organism to the largest creatures on Earth, every living thing is defined by its genes. With recent advancements, scientists can change an organism’s fundamental features in record time using gene editing tools such as CRISPR. But where did this medical marvel come from and how does it work? Andrea M. Henle … Continue reading
