Most people who have attended high school will recall their science classes. High school students usually have two contesting attitudes toward these classes - they either really love them or they hate them.
Regardless of how much a student likes or dislikes sciences such as Chemistry, Biology and Physics, they will usually enjoy performing the experiments. For instance, one of the first scientific experiments children perform in grade school is planting a seed, caring for it and watching it grow.
Sometimes these plants are vegetables such as carrots, or flowers such as marigolds. In professional experiments, however, the seeds may be natural or they may have been treated in some way, with special chemicals or even non-dangerous amounts of radiation.
In these professional cases, the experiment will be slightly more complicated and more interesting than simply watching the plant grow. These experiments will consist of watching for, and documenting, the differences between the treated and non-treated plant species.
Other interesting experiments that students anticipate, with dread or with glee, involve sulphur. Sulphur has a terrible odor. It smells like rotten eggs. Anyone who has enjoyed the benefits of a natural sulphur springs bath will recall the horrible odor of the pleasant earth-warmed water and steam. The smoothing effects on the skin far outweigh, however, the foul but tolerable odor.
Most high school students will have been introduced to the typical chemist's type of black-topped desk with taps and sinks which usually accommodate seating for two. Chemistry classes are fun for students who enjoy learning how the elements of the earth and air combine to form different substances.
This type of experimentation, performed under the guidance of a science/chemistry teacher is enlightening and memorable. Every student who has taken high school science at some level will have fond memories of Bunsen burners. Bunsen burners are small gas burners with a single flame and are named after Robert Bunsen, who developed them.
Bunsen burners are used in chemistry classes and by professional chemists to heat substances. The special thing about them is that the heat is extremely controllable, meaning that the person conducting the experiment can bring a substance to a very fine temperature point.
This amount of control is one of the critical factors students might recall about the theory behind condensing boilers. Because they require little energy to produce a great deal of heat, condensing boilers are becoming popular as energy efficient thermal systems, replacing gas and oil forced air heating systems.
