When educating your children at home, you have the freedom to teach them sound science that is presented from a Christian worldview. “Christian Kids Explore Earth and Space,” geared at elementary students, fits the bill very well. This text is part of a series by Stephanie L. Redmond which include Biology, Chemistry, and Physics. I enjoyed teaching from this text for a number of reasons including: it requires little to no teacher prep time; it is enjoyable to work through; being from a Christian worldview, it is God-honoring; and it is written in a conversational tone that is easy to read aloud and appeals to the younger audience.
The text has 24 lessons, 2 on the Earth in general (including Creation); 5 covering the lithosphere; 4 covering the hydrosphere; 4 covering the atmosphere; 5 covering weather; and 4 covering all of outer space. The maps, forms and coloring sheets are reproducible. An applicable scripture has been chosen for each lesson. In addition, there is an appendix of recipes and additional activities, another on how to make a folderbook, and another including additional books and resources. We took the book to our local copy center and had them cut off the binding. Then we separated the reproducible sheets and had the text spiral-bound with all the glossaries and appendices.
Altogether, I found this course to be a good core text for my second-grader that was easily supplemented in a few areas. I will be using it again with my younger kids when they hit second grade. And although my second-grader and I completed the entire course, we definitely amended and expanded it to be more in-depth. One example of this was finding all nine planets covered in one short chapter! I thought this was neglecting an opportunity to excite kids about outer space, so we expanded on that section with outside materials. There is no chapter at all about biomes, which I found startling, as there is so much to intrigue children about the variety of habitats and temperature zones on this planet we call home. Again, we supplemented the study of Earth with outside materials.
In a few of the chapters it seemed as though the bulk of the reading is about the author’s own experiences, although this contributes to the ‘talking to a young child’ tone. One of the main things I noticed about Christian Kids Explore was the lack of consistency in material from chapter to chapter. It is a curious mix of technical definitions and conversational banter.
It’s always great to find a science course that gives glory to God for his creation. The first lesson was about Creation, but neglected the “on the first day, on the second day…” so we supplemented that with some reading from Genesis. In Lesson three she goes over the theory of Pangea and the worldwide flood, how some scientists and theologians have conflicting ideas. She presents it flawlessly and intelligently. Although the coloring sheets are beautiful, they have a lot of black space that can’t be colored. In addition, there is one sheet for the entire unit, not individual sheets to work on while mom reads each chapter.
The benefits in this book for the upper elementary students include lots of definitions in the margins and timelines listing scientists and scientific discoveries. One thing that would have been helpful was a ‘year-long list of copies to be made’ in case you don’t have a copier at home to do it chapter by chapter. I think this book is a good value, especially if you supplement with library materials instead of buying them.

What You Should Know Before You Buy A Glass Aquarium
Many people when buying their first aquarium, vacillate back and forth about whether to choose a glass aquarium or an acrylic one. Here are some tips on glass aquariums that may help you to make up your mind.
The quality of a glass aquarium depends on the type of sealant used as well as the type and thickness of the glass. There are two types of glass aquariums, those that are meant to hold water based creatures such as fish. And those that are meant to hold non-water based entities such as plants, turtles, lizards, and so on. If your intent is to house fish in your aquarium, you need to be sure that your aquarium of interest had it’s sides bonded with sealant especially meant to hold water. If not, you could find that your fish tank is subject to leaks.
The typical glass aquarium is made of one of two types of glass – plate glass or tempered glass. Plate glass is a very heavy glass, it’s over two times the weight of plexiglass (or acrylic) which is used in many fish tanks. Contrary to plexiglass, however, plate glass is extremely scratch resistant. It’s also resistant to stains. Tempered glass is a bit less smooth than plate glass. Each type of glass breaks different as well. When plate glass breaks, it tends to break into large pieces. When tempered glass breaks, however, it usually shatters into a lot of pieces. For all practical purposes, this means that if your plate glass fish tank breaks, you’ll probably only have a crack at the point of the break, and it’s a good chance that your fish will still be safe. If your tempered glass aquarium breaks, however, it’s probable that the entire aquarium side will be shattered and you’ll lose all your fish.
Glass aquariums are not as good at retaining heat as acrylic tanks. So, dependent on the weather conditions where you live, you will probably be more reliant on your tank thermostat and heater to keep the water in the aquarium at the appropriate temperatures. If you live in a warm weather climate such as Florida or Nevada, heat loss will most likely not be an issue.
Since glass tanks are heavier than acrylic tanks, you’ll want to be extra careful when choosing an appropriate aquarium stand. It’s true that most of the aquarium weight will come from the water itself. But, when determining if the flooring supports are strong e
nough to safely hold your fish tank, you have to include all weight variables – the weight of the tank, the water, and the stand.
It used to be that if you wanted aquariums that were shaped differently than the normal rectangular shape, you had to purchase an acrylic tank. This is because glass tanks were made from planes of glass, limiting them to rectangular shapes, while acrylic tanks were molded, letting them take the shape of the mold, however irregular it might be. Lately, however, new technology has allowed the creation of glass aquariums with curvy and other unique shapes, rounded corners, and seamless edges. Acrylic tanks still hold the edge in the number of unique shapes that can be created but aquarium glass technology is light years away from where it was only a few years ago.
