When I was growing up everybody had a TV with maybe 5 or 6 channels. There wasn't anything known as cable TV. At my house we got channels 4, 6, 10, 12 and 18. Later on we also got channel 17 which was Fox TV. I can remember when I first heard about HBO which was a box that only got you HBO and nothing else. That privelage would cost a household maybe $50.
This article teaches kids about the Crystal Farming and gives a handful of totally fun activities to experiment with for their homeschool science learning (including rock candy and homemade geodes). It’s also good for boy scouts working on a badge, or for any kids that love science experiments. These experiments are part of a homeschool science program that I teach, and I promise your kids will love it.
This article teaches kids about chemistry and is an excellent introduction to the totally fun activities in homeschool chemistry (including exothermic reactions, phase shifts, and acid indicators). It’s also good for boy scouts working on a badge, or for any kids that love science experiments.

Nowadays, with the price (and pollution levels) of traditional energy sources such as burning coal and other combustible resources being extremely high, countries are forced to look at other, more renewable energy sources to meet their needs. Making use of wind to power our lives is one way that we, and our governments, can help to reduce the stress on an already battered environment, and also help the economy while we're at it.
The metric system has taken over the world. Meters, grams, liters, etc., are everywhere; the number of countries that don't use the metric system can be counted on the fingers of single hand. Now that it is so firmly established, it would seem appropriate to update it by adding a few more important measurements that still rely on cumbersome, old-fashioned non-metric units - the hours of the day and the degrees of a circle.
The world's weather can have an enormous impact on a local scale. From a whirlwind to a cyclone, or an ice storm to a drought, the weather takes its toll. But did you know that the whole world's weather is capable of making the whole Earth move? As it rotates, the Earth wobbles as it spins on its axis. And as it slows down, the planet develops a host of different wobbles, ranging in time period from a few minutes to billions of years.
On a summer day in Paris in 1783, Jaques Charles did something as tonishing. He roared 3,000 feet above ground in a balloon of rubber-coated silk bag filled with lighter-than-air hydrogen gas. Though this event had no significance for the next two centuries, yet Charles had launched a quest to harness the power of hydrogen for transportation.
