    My childhood was plagued with overcomplicated electronics kits with massive breadboards and a tangle of resistors. After completing several of the 40 experiments, I feel this kit is much more concise than many and easy to construct. This hands-on lab is designed especially for those who need a knowledge of electronics leading to a career in electronics, computers or robotics. This Tronix Book 1 lab kit will provide a good foundation in basic electronics concepts and components. A 93-page workbook provides 40 briefly described lessons that follow a 3-step process: taking inventory of parts needed; building the circuitry; and performing the experiment (with procedure and observation). Experiments range from basic electronics lessons (how to use the circuit board, reading values, etc.) to component lessons (how diodes, resistors, photocells, transistors, etc. work) to more complicated electronic project lessons. My favorite experiment was the moisture detector. Others include the light controller, police siren and insanity alarm game. Additionally, 13 pages of lessons cover basic DC electronics (Ohm’s, Kirchhoff’s voltage and current laws, and resistors in parallel and in series). At the end of the workbook are 9 pages of Build-the-Schematic exercises, in which the more advanced student will view a schematic, read the theory behind each item and follow the procedure to build. Students can also fill in the date of each schematic’s completion. Parts are identified visually and also according to lab used: includes a 6.5” x 1.5” breadboard, a 9V battery, ceramic disc capacitors, light emitting diodes, an integrated circuits/timer, a photocell, a battery snap, a timer, 3 standard LEDs,2 silicon rectifier, 4 pnp transistors, a speaker, resistors, a diode, a push-button switch, potentiometer, semiconductors, and 20 solid wires at different OHM ratings. While most helpful if learning alongside someone with some electrical experience, the variety of in-depth experiments allow high school students to have plenty of fun while learning ohm’s law, circuits in parallel versus series and voltage principals. ~ Steve

    If you crossed a common, ordinary pocket microscope with a Swiss Army knife, you just might end up with the X-Scope. Truly the "Cadillac" of magnification tools, this handy little pocket-size 30x microscope also includes an 8x pull-out telescope, a 9x magnifying hand lens, a clock, a whistle, a compass and a flashlight! Ok, if you aren't bedazzled with all those extra features, you will definitely be impressed with the quality of magnification and the bright, sharp viewing provided by the LED bulb. Just flip the light switch, place the object you want to observe underneath, and look through the lens on the top. Compared to other pocket microscopes in our office, this one allowed us to see all those Asian beetles in our office in much more detail! Jess

    Learning about electrical circuits could not be easier. The child uses conductive (colored) dough as the “wires” and inserts LEDs with chubby contact points into the dough. Put two separate pieces of dough on the 9-volt battery-powered work table, poke the red wire lead into one piece of dough, the black wire lead into the other piece, and stick an LED so that the contact points touch both pieces of dough, and the LED lights up, showing that the circuit is complete. After covering these basics, other experiments are done using guide cards that fit into a recessed area under a clear plastic cover. The cute guide cards show exactly where to place the red, blue and yellow conductive dough, the white non-conductive dough, the wire leads, and up to four red and four yellow LEDs. Concepts covered include + and -, conductive and non-conductive, and series and parallel connections, all just by playing with dough!

       Take a different approach to teaching phonics and reading with your students. The Stretch & Catch Method can help children learn to read in 10 minutes a day. Whether you are teaching your children at home or they need extra help with their classroom learning, this method is easy and can be a tremendous help.

      The instructions for employing the Stretch & Catch Method are presented in a systematic fashion, so that anyone can use it. Developed by Amanda McNamara Lowe, her goal is to help all children learn to read. To learn to read, children must understand how words work. Stretch & Catch will help them see patterns in words, sound out the words, hear the sounds, feel the sounds, and use their fingers to “catch” the sounds.

      There are nine chapters in the book; chapter one is the explanation, preparation, and assessment portion of the book. This chapter is very important to understanding the Stretch & Catch methodology, The Word List (TWL), daily reading and placement. Stretch & Catch is a technique that uses the fingers to represent word sounds – Stretch is sounding out the word by raising one finger at a time per sound, Catch is saying all the sounds together, quickly, while bringing the fingers into a fist. Example: Spelling the word ‘dot’ – say /d/ and raise the first finger, say /o/ and raise the second finger, say /t/ and raise the third finger; say the word fast and pull the three fingers into a fist. My example is a simplified explanation of the methodology, and there is a scripted dialogue to be used along with it (8 steps). The Word Lists (TWL) are five colored lists of high-frequency words that the student learns to identify, these words make up 50% to 60% of the child’s reading and must be mastered. TWL are found in chapters 3 through 7. Assessments for TWL are found in chapter one, but you won’t use them until the appropriate time. Daily Reading to and with your child is a very important part of this program. There are no designated readers, but the author suggests reading alphabet and ABC books for children who need to learn basic letter sounds (children beginning with chapter two of this book). Early reader books for children in chapters three through six of this book, fluent readers (children in chapters 7-9) can read anything of interest to them. Chapter One includes a vital assessment tool to help you determine where to begin in this program. For children who need to learn basic letter sounds, begin with chapter two. Others start with chapter three, where Stretch & Catch begins teaching letter patterns. The word ‘feature’ is used to refer to the spelling pattern(s) being introduced in each chapter – there are 26 features total. 

      Chapter Two teaches the basic alphabet sounds (feature 1) and instructions are given at the beginning of the chapter. The author suggests that you have index cards on which to write the letters (lowercase and uppercase on separate cards), consonants in one color and vowels in another. Spend one week per letter for children who are being introduced to letters and sounds, one per day for those who just need review. Each letter has a key word that will be associated with it throughout the lessons. Only short vowels are presented in chapters two and three.

      Chapter Three introduces the first TWL words (you will want to use index cards to write them on for practice), Daily Reading suggestions, explanation of short vowels using Stretch & Catch, and scripted templates for teaching ‘features’ 2 through 6. There are two templates, one that is adult-led and another for child-led. These are examples of how to teach the lessons included in the chapter. You will then find lessons (lists of words) to use within the template for teaching each day. This chapter also includes some optional lessons.

      Chapter Four focuses on beginning and ending blends (features 7-11), and chapter five is beginning and ending digraphs (features 12-13). These chapters follow the same format as chapter three: TWL words, Daily Reading suggestion, explanation of the features in the chapter, templates, lessons, and examples.

      Chapters 6-9 cover features 14-26, and at this point your child is no longer considered a beginning reader. Lessons become child-led and you (parent/teacher) are there to be a guide. Children will learn about silent e, common long vowels, diphthongs, and r-controlled vowel patterns. Each chapter includes the TWL words, Daily Reading suggestions, explanation of the ‘features,’ an optional template for introducing the ‘features,’ child-led templates, lessons, and examples.

      Children should be reading fluently upon completion of this book, and just 10 minutes a day! Lessons may take more than ten minutes a day in the beginning; but once the methodology is mastered, teacher and student will love the ease of doing a short lesson each day. The method is multi-sensory and repetitive, which helps children to commit things to memory. The more a child is exposed to letters, sounds, and words, the quicker they will be imprinted on the brain (memorized). This method works well with beginning readers, but can also help struggling readers. 137-pgs, p/b. ~ Donna

    Originally presented as a series of lectures at Cambridge University, this comprehensive history looks at the fall of Rome as facilitated from within and without. Author J. B. Bury's explanation of the causes of Rome's downfall show how the ever-expanding and aggressive attacks by the Goths, Huns, Vandals, and Franks, combined with a relaxed attitude and downsizing within the Empire, led to the eventual end of the once mighty Roman Empire. Rather than having chapters, the book is organized by lecture – 15 in all – and works steadily through the progression of events. This sequence can be seen in the lecture titles as follows: Lecture 1: Germans and Their Wanderings, 2: Roman Empire and the Germans, 3: Clash of Rome and the Barbarians, 4: Visigothic Entry in to the Empire, 5: Raiding of Italy and Gaul, 6: Visigoths in Italy and in Gaul, 7: Gaul, Spain, and Africa in Transition, 8: A New Menace to the Empire, 9: Attila's Attack on Gaul and Italy, 10: Decline of the Roman Power in the West, 11: Ostrogothic Conquest of Italy, 12: Visigoths and Franks in Gaul, 13: Reign of Clovis, 14: Lombard Invasion of Italy, 15: The Lombard Law. A timeless text that enlightens us to the groundwork for the modern era of Europe. 296 pgs, pb. – Zach
