    in the form of rain fog dew water vapor humidity etc affects materials in several ways A material may absorb the water and expand then as it dries out and contracts this fluctuation can stress the material A similar effect happens during freeze thaw cycles Thermal shock from daytime rain showers can cause chemical and physical failures Rain can reduce chemical deterioration by washing off pollution or it can hasten deterioration by rinsing off dirt and dust accumulation which often serve as a protective coating against UV radiation Rain may also physically deteriorate a surface Water acts as a solvent which means it can dissolve minerals Acid rain is particularly damaging Contact with water in any form can accelerate oxidation The total duration that a surface is wet also has an effect The weathering result of a drizzle lasting several hours is much greater than if a lot of rain falls in just a few minutes Acid Rain Acid weathering and etching of materials has become a problem in recent years due to acid rain This is because of factories putting pollution into the air which then combines with water to fall down to earth as acid rain The Midwest is the worst producer of acid rain but that area isn t affected because most of the pollution is blown to the Eastern U S Northeastern U S or Canada Carbonic acid is one of the usual acids formed when carbon dioxide combines with water The most affected mineral is calcite which is found in marble and limestone Consequently many buildings statues and monuments made of these materials are slowly but surely weathering away Did you know that carbonic acid is an ingredient in carbonated soft drinks People drink the same product that weathers rocks New River s Weathering Test Lab In the weathering industry the two major benchmark climates for weathering tests are a subtropical climate southern Florida and a desert environment central Arizona These sites are recognized around the world as the most extreme climates for materials exposed outdoors Central Arizona provides high levels of UV solar radiation elevated temperatures and an arid climate all of which are crucial factors in the weathering process It also has a wide range of temperatures which may fluctuate from 30 50 degrees C between day and night Here automotive interior materials experience the highest stress compared to other climates An unpolluted desert environment is ideal for testing materials under these conditions Most people don t realize that New River is home to Arizona s premier weathering testing laboratory Have you ever noticed that large building surrounded by what looks like a bunch of solar collectors up on a ridge off New River Road just west of I 17 A sign by the road to the 40 acre material testing and evaluation site simply says DSET My husband Rich Olsen is the Weathering Manager at DSET leading a staff of specially trained scientists engineers and technicians DSET offers desert exposure testing for

    in the 1880 s for ladies who were afraid of the high bicycles and for gentlemen such as doctors and clergymen who preferred to ride with more dignity Then safety bicycles much like today s bicycles were invented While the highboys remained in use for more than a decade eventually the safety bicycle won out The safety bicycle returned to two wheels of the same size but it could go as fast as the high wheeled ones due to a major improvement Pedals drove the rear wheel by a chain and sprocket as they do today The chain was arranged so that turning the pedals once made the back wheel turn more than once around The rider sat lower and more comfortably between the wheels Rubber tires were filled with air making for a softer ride Coaster brakes were also added In the 1890 s bicycling became so popular that people went without other luxuries and even necessities so they could afford the best possible bicycle At that time bicycles were the fastest wheels on the road Bicycles were used for recreation as well as transportation Sunday afternoon rides became popular with women participating as actively as the men The tandem bicycle built for two became a fad There were even some bicycles for four riders It has been said that the wheel was the single greatest invention in the history of mankind and the most useful application of the wheel may well be the bicycle Most people don t realize how bicycles influenced our present way of life Bicycling was the first athletic activity to bring women out of the parlor They stopped wearing hoopskirts bustles and cumbersome clothes and changed to shorter skirts bloomers culottes and apparel more practical for bicycling In addition the bicycle literally paved the way for the automobile Many early automobile engineers and manufacturers started out as bicycle builders The first automobiles had slim tires and spoked wheels just like bicycles They were given their test runs on the smooth roads that had been demanded by bicyclists The first motorcycle was a gasoline powered bicycle Even Wilbur and Orville Wright s historic flying machine was designed in their bicycle shop After the introduction of automobiles bicycles slipped out of favor for more than half a century Bicycle manufacturers resorted to selling two wheelers and tricycles as toys for children Then in the 1960 s biking enjoyed a revival as it once again gained popularity with adults Circumstances that brought the bicycle back included the need for exercise an increase in leisure time interest in the outdoors concern for the environment and a desire to return to a simpler way of life Today s bicycles represent over two centuries of development Gear shifts were added to modern bicycles for changing speeds and making pedaling easier Space age materials and engineering provide maximum performance and relatively low maintenance Types of bikes include the English 3 speed of the 1960 s 10 speed derailleur bikes from the

    and problem solving skills There are short term and long term goals to work towards from getting as many Zoombinis as possible through one puzzle to getting all 625 possible Zoombinis to Zoombiniville The puzzles have four levels from not so easy to very very hard Recommended for ages 8 12 but my oldest son is a logical thinker so he had it mastered at age 6 JumpStart Series The JumpStart series of grade level multi subject edu tainment software includes JumpStart Baby Toddler Preschool Pre K Kindergarten First Grade Second Grade Third Grade Fourth Grade Fifth Grade Sixth Grade We have re used the grade level programs with all three of our children When we first got these games for our oldest son we gave them to him during the summer before he began the specified grade level in school to play as a fun head start JumpStart Baby Toddler Second and Third Grades are my favorites We have the original JumpStart Fourth Grade which takes place in a spooky Haunted Mansion but I ve heard that they changed it since then perhaps because of complaints that it was too scary JumpStart Fifth Grade is probably the most difficult for its corresponding grade Over the years they have also added many more subject specific titles such as JumpStart Typing Jump Start Spanish JumpStart Explorers etc all of which are enjoyed by kids Liberty s Kids The Learning Company has produced a Liberty s Kids CD ROM for ages 7 12 It contains seven challenging re playable events with more than 30 interactive animated characters Kids can watch mini movies from the TV show interview historical characters play puzzles and games create and print a newspaper Basically players go on a scavenger hunt to collect missing objects and interview characters while answering Who What Where Why and How questions In doing so they gather facts about major historical events such as the Boston Tea Party and the writing of The Declaration of Independence This information is recorded in a notebook and later pieced together into a front page story so this game introduces children to journalism as well as history The CD ROM also contains quizzes and a reference guide with a wealth of historical information Carmen Sandiego series In Where in the USA is Carmen Sandiego you chase Carmen across the United States researching places and solving clues along the way In Where in the World is Carmen Sandiego you chase her and her henchmen around the world while researching countries and solving clues In Where in Time is Carmen Sandiego you use a time machine to zip back and forth through time to apprehend the criminals using clues from reference material provided Along the way you learn about history geography and cultures while utilizing deductive reasoning and logical thinking skills all while playing a fun detective game at the same time The information contained in these games is excellent and interesting and all of the extra features such as sound clips and photo images provided in the Deluxe versions are well worth it Carmen Sandiego Junior doesn t have as much content but younger kids ages 5 8 will like it The others are best for ages 9 and up An interesting thing happened when we were playing Carmen Sandiego one day We were in the Louisiana Bayou and there was some really cool Cajun music recorded live playing in the background Of course the boys always have the sound turned way up The phone rang and my husband answered it in the same room The sales person on the other end was all apologetic thinking that he was interrupting a party That s how realistic this game is Oregon Trail In this game players age 8 and up guide a group of pioneers from Independence Missouri to a destination out West such as Oregon California or Utah You begin by planning the trip buying supplies getting advice joining a wagon train Then as you travel you make decisions about how to cross difficult rivers and hills which places to trade hunt or stop and rest and how to treat members of the party who are injured or sick There are three levels of difficulty lots of choices to make different routes to take and unexpected scenarios that come up which you have to deal with just like in real life Along the way you learn about native plants animals history and more Oregon Trail I is the original since it s an old program its graphics are poor Oregon Trail II is old now too and a lot simpler than its sequels but it s still good I didn t like Oregon Trail 3 when it came out because it didn t have the neat western music score at the beginning that Oregon Trail II had which really set the mood The later ones are good though each sequel getting progressively more detailed in the animation and digitized sounds Music Ace and Music Ace 2 Music Ace and its sequel are an excellent introduction to music for ages 8 and up They are fun and engaging while detailed enough to serve as a complete beginning music curriculum Each of these programs contains 24 self paced tutorials that teach music fundamentals theory and listening skills in a painless manner Music Ace begins with the basics such as the staffs treble bass grand scales octaves keyboard basics pitch identification note reading sharps and flats whole and half steps Musical games and a Music Doodle Pad are included Music Ace 2 progresses to topics such as standard notation tempo rhythm quarter notes eighth notes rests measures melody harmony syncopation half notes and ties dotted quarter notes sixteenth notes and much more Sim series The Maxis simulation games are generally good for ages 6 and up SimCity Classic 2000 3000 and 4 all provide a realistic introduction to city planning and zoning budgeting government business cause and effect scenarios In SimTower
