    This new edition of Exploring Creation with Chemistry makes chemistry approachable and doable in a homeschool setting. Now authored by Kristy Plourde, you will notice a few changes from previous editions.

    The chapter order has been changed from the previous editions (1st and 2nd) of the curriculum. There are still 16 modules measurement, units, and the scientific method, atoms and molecules, atomic structure, molecular structure, polyatomic ions and molecular geometry, changes in matter and chemical reactions, describing chemical reactions, stoichiometry, acid-base chemistry, chemistry of solutions, gas phase, energy/heat and temperature, thermodynamics, kinetics, chemical equilibrium, and reduction-oxidation reactions. The front of the book offers a suggestion on how to use the book and the length of time typically spent to complete the course. "On Your Own" questions are found throughout the modules and are to be completed as the student reads the text answers are included at the end of the module. "Review Question" and "Practice Problems" are found at the end of each module to help students recall and apply important concepts presented in that module. The text is generous with examples, illustrations, and photos for clarity of concepts.

    Some helpful resources are found at the back of the text glossary, tables/laws/equations, extra practice problems for each module, and a complete list of lab supplies.

    Experiments are homeschool-friendly and can be completed using the lab kit (#008778) that is assembled by Nature's Workshop and items that are easily accessible. If you want to do more advanced experiments, you can purchase the MicroChem Lab Kit (#020028). These experiments aren't printed in the student text, but are mentioned and marked by a flask and test tube symbol along with where that experiment can be found in the MicroChem Manual. The experiments in this 3rd edition are a combination of some new ones and the tried-and-true from the previous editions. If you don't want or need to purchase the lab kit (#008778), the required items to complete experiments are a 1 mass scale (0 to 500 grams), blue and red litmus paper, 1 thermometer (-10 to 110 degrees C). If you have these three items, the text makes suggestions within the experiments for household substitutions of the other items needed.

    A special website is available to accompany this course, offering web links and additional information for specific concepts. The web address is printed in the front of the text with instructions for access. Textbook is now in the 4th printing. ~ Donna.

    Chemistry labs can be scary and overwhelming, especially if you don't have a curriculum that lays them out for you. It can be expensive to buy the equipment and many of the chemicals are restricted and difficult to obtain.

    MicroChem Experiment Lab is a kit that takes away some of the pressure and expense of those high school chemistry labs. This kit includes scaled-down amounts of chemicals (about 1/100th the usual amount) and is enough to do experiments about 5 times. By scaling back on the chemicals and using plastic equipment (where possible) the cost is controlled a bit and there is less of a problem with chemical disposal at the end of the course. Chemicals come in dropping' bottles, so they are ready for use. No mixing and less spilling is a definite benefit to this kit. Experiments may cause for a drop' or drops' of a chemical, so the special bottles are great for dispensation.

    The kit includes a 119-page manual that contains introductory information, how to use it, and safety information. The manual includes experiments and instruction for each goals, materials/equipment needed, background information, and step-by-step procedures. Suggested answers are given for questions in each experiment, and solutions to experiments are included at the back of the manual. If you are already using a curriculum and just need labs, an included chart shows correlation to A Beka Chemistry, 2nd ed.; ACE Chemistry, 1996 ed.; Alpha Omega Publications, grade 11 Chemistry; Apologia Exploring Creation with Chemistry; Bob Jones Chemistry, 3rd ed.; Glencoe Science, Chemistry: Matter and Change; and Prentice Hall, Chemistry. If you are using a different curriculum and just need the labs, just match the labs up to the concept you are studying for a lab companion. This kit isn't a complete chemistry curriculum, so you should be using a course text for explanations; there is also an assumption that students using this kit have knowledge of Algebra.

    There is a lengthy list of items included in the kit. Call our customer service if interested in the complete list; however, the chemicals included are acetic acid, bromophenol blue indicator, calcium nitrate, copper nitrate, glycerin, hydrochloric acid, lead nitrate, nickel nitrate, phenolphthalein indicator paper, potassium hydroxide, potassium iodide, sodium acetate, sodium hydroxide, sodium oxalate, sodium sulfate, sodium thiosulfate, universal indicator paper, zinc nitrate, magnesium sulfate, potassium hydrogen phthalate, cetyl alcohol, and palmitic acid liquids are in 0.1M dropping bottles.

    As with all kits, there is always a list of items you will need to supply. Most are household items black paper, books, felt-tip pens, water soluble ink, distilled water, food coloring, graph paper, ice, matches, natural indicators, paper towels, clear tape, printed paper, scissors, shallow pan, table salt, stapler, source of heat (microwave, stove, etc.), stopwatch or watch with a second hand, table sugar, vinegar, and white paper. Another item mentioned in the experiments is a voltmeter, which you would need to provide. You can either skip those labs or a voltmeter can be purchased at a minimal cost.

    These are real chemistry labs intended for the college-prep level of learning and can be used to really beef-up your high school chemistry course. ~ Donna

    Supplies included in this kit: instruction manual, 9-volt battery, 15mL, 30mL, 150mL plastic beakers, 50mL glass beaker, Capillary tubes, Chromatography paper, Conductivity apparatus, Cotton swabs, Electrolysis device, Felt-tip pen with black, water-soluble ink, 10mL plastic, graduated cylinder, 1.0mL measuring spoon, Graduated, mini, and thin stem pipettes, Plastic toothpicks, 96-well reaction plate, 24-well reaction plate, Rubber bands, 15 cm ruler, Safety goggles, Fine sandpaper, Spring clamp, 6x50 mm test tubes, 12x75 mm test tubes, Celsius thermometer (-10° to 102°C), Washing bottle, Wire gauze, Wood splints, Lab Manual, Acetic acid, Calcium nitrate, Copper nitrate, Hydrochloric acid, Lead nitrate, Potassium Hydroxide, Potassium iodide, Sodium acetate, Sodium hydroxide, Sodium oxalate, Sodium sulfate, Sodium thiosulfate, Zinc nitrate, Magnesium sulfate, Potassium hydrogen phthalate, Cetyl alcohol, Palmitic acid, Bromophenol blue indicator, Glycerin, Phenolphthalein indicator paper, Universal indicator paper, Copper, Lead, Nickel, Zinc. – all solutions are in 0.1M bottles.

    If your family is like mine - captivated by the real science behind the plethora of television crime shows, then this book may be perfect for you. This resource brings the scientific study of crime scenes into the home and school arena. While the labs are designed for groups, you can easily do these as a family (or in a co-op) if you are willing to invest the time to set the crime scene stage.

    Divided into 4 sections, each covers a different branch of science. The first section, Critical Thinking, lays the foundational principles of science and reinforces observation skills (handwriting and typewriting comparisons,) experimentation (shoe impressions) and logical thinking. Physical Science employs techniques such as analysis of unknown mixtures, fibers and fingerprinting. In the Life Science section, students concentrate on evidence left at crime sciences by living things and study the principles of inheritance, DNA, blood typing, dental identification, and forensic etymology. The final section, Earth Science, offers lessons on mummification, skeletal evidence, and archaeological evidence. All in all, this supplemental resource book offers 68 lessons and labs (most lessons have one accompanying lab, some have two) designed to bring a fresh enthusiasm on the importance of "whys" of learning science. Household items and additional lab equipment required (microscope, glass slides and cover slips, test tubes, pH paper, beakers, filter paper, Plaster of Paris, and various chemicals. Information to order an Edvotek DNA Kit is included for the DNA labs).

    A brief personal note, I used the previous edition of this book with my teens and they still talk about the science they learned. Real life science learned and remembered makes for one happy homeschool mom! We performed the majority of activities in the book, making changes to the readily available supplies, some of the experiments we discussed and did not perform due to the difficulty of obtaining materials. Noteworthy:while the mock crimes are presented in a discerning manner, they do represent a wide variety of fact- based crimes. As a family, you may elect to skip over some of the lessons within the pages. Reproducible for classroom use. sc ~Deanne
