My son has a 2 week break from his Great Books & Latin courses so we've been catching up on science labs. I'm beginning to think that like the need to teach practical theology within the context of our post-modern world, there is also a need to teach science recognizing that we live in a post-modern world.
One common mistake of today's post-modern man or woman is realizing we often know less than we really think we know. For the post-modern science student, the ignorance may be even greater because they lack enough world experience to see how much occurs without a carefully designed lesson plan. When we memorize a list or table of facts, do we really know it? So what is it that we do know, and what is it that we don't?
One nice discovery on my search for links to complement our Fizz, Bubble, and Flash experiments, was the Rough Science science reality show. If you are a Netflix subscriber, you can stream these episodes any time for free. A team of scientists (chemist, physicist, biologist) is dropped in a deserted area with few materials and a challenge to design, make, or find something in the surrounding terrain. How many of us can do this? Maybe we need to think more about our science and get out of the printed page. The first episode we watched challenged scientists to find gold in a gold mining area, purify it and quantitate it using only materials they could find in deserted saw mill.
The experiments we tinkered with this week included Electrolysis of Water using a 9 volt battery, water, and copper wires. The Rough Science team washing using electroysis to make silver iodide so that they could make a camera.
To top off our electrolysis learning we also watched this homemade Exploding Hydrogen video. It was pretty good! Even the outtakes!
