Growing Plants in Test Tubes | Science Experiments | Steve Spangler Science

Reveal the science behind sprouting seeds and water conservation. Nothing compares to eating fresh vegetables picked right out of the garden! But, what’s happening out of sight in the soil of that garden? Here are two plant-growing activities you can do anytime of the year to discover the science behind those growing marvels and to discover a unique way to conserve water, too.

Open-book, collaborative quiz: Recipe for engagement – by Michael Jansen

Open-book, collaborative quiz: Recipe for engagement – by Michael Jansen

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

Build the Simplest Electric Motor – submitted by Flinn Scientific Canada

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

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
