The Pre-Level I Chemistry Laboratory Workbook includes ten hands-on experiments that incorporate the chemistry concepts found in the student text. The experiments include an introduction to atoms and molecules, an introduction to acid/base chemistry, mixtures, polymer chemistry and an introduction to proteins and DNA. The experiments are teacher directed and require the Pre-Level I Chemistry Teacher's Manual.

The Focus On Middle School Physics Teacher’s Manual accompanies the Focus On Middle School Physics Laboratory Workbook and the Focus On Middle School Physics Student Textbook. The Teacher’s Manual includes directions for each experiment, a list of materials needed, overall objectives for each experiment, suggested questions to use in guided inquiry, and additional information about concepts covered in the Focus On Middle School Physics Student Textbook.The Focus On Middle School Physics Teacher’s Manual contains 10 black and white chapters. Grades 5-8.

Sometimes the secret to stashing your valuables is as simple as a hollowed out book. In other cases, whatever it is you’re intending to protect may be highly confidential information that requires increased security. A hollow book just won’t do. This book isn’t hollow; in it, we will discuss various hiding places, from the simple and straight forward to the complex – a place to hide your cash from your light-fingered roommate or a place where your family heirlooms may be safe from the most cunning of jewelry thieves. We will also look at secret hiding places specific to travel, as tourists are often a prime target for petty theft or burglary.The use of secret hiding places isn’t limited to hiding items of value; hiding places can also be used to conceal weapons. Carrying a weapon on your person at all times will allow you to defend yourself should the need arise, without provoking suspicion in your assailant or making those around you feel threatened. We’ll provide a few methods by which to hide both valuables and weapons on your person.Learn how to hide your treasures, items and documents securely:1) In Your Home2) On The Road3) When You're Traveling4) From Hackers/Cyber Thievesand more...

This comprehensive guide discusses the care, breeding, and natural history of these popular pets and covers all the species and subspecies of box turtles present in the reptile hobby, including North American box turtles and Asian box turtles of the genus Cuora. The author, an expert on box turtles, who has studied them, bred them in captivity, and rehabilitated injured box turtles for release back into nature, provides in-depth discussion of hibernation- a critical topic for the health of these creatures.
