Nearly 200 Catholic scientists from the past thousand years are overviewed by means of brief biographies, with dates and places where each scientist lived and worked. The scientists are listed in chronological order with an alphabetical index in back. The author's primary source of information is the Catholic Encyclopedia of 1913 (which can be found online at http://www.newadvent.org). Her main purposes in working on this project are "to show students that Catholics have always been scientists" and "that there is nothing incompatible between science and the Catholic faith."

I have received QUITE a few e-mails from Catholic homeschoolers (particularly ones using Protestant science texts - which tend to highlight the religious beliefs of Protestant scientists) who want to know how to find out which scientists were Catholic. This booklet is a good place to start. Even though the Catholic Encyclopedia is available free online, this booklet is a simple and easy way of finding what you're looking for (particularly because the Catholic Encyclopedia online doesn't yet have a search feature).

One of the things that fascinates me most about Wisconsin winters (I grew up in California) are the animal tracks clearly visible in the snow. It leaves a temporary record of what was visiting while you weren't looking - what a fascinating thing for homeschoolers to look into. Animal Tracks will make a nice resource for younger students to study local wildlife. This is an illustrated narrative of animal life with a little guessing game on each page based on the tracks left by each animal. The book also contains four pages of identified tracks (including humans) and instructions for "preserving" the tracks with plaster of paris or by tracing. An excellent way to spark children's interest in nature.

A beautifully illustrated look at where various animals go when it snows and how they prepare for winter. We learn details of the migration of various animals (such as birds, butterflies and bats), animals that hibernate, animals that store up food for the winter and animals that have to find their food throughout the winter. Includes instructions for feeding birds and other wild animals in your own backyard.

AntWorks was one of the highlights of our summer natural history studies! This simple kit became a quirky centerpiece on our dinner table, engaging the entire family from the 18-month-old who insists that they are "Nants" to a 40-something daddy. AntWorks comes as a thick-walled plastic home with a stable base; this became important as the little ones spent time watching the ants. We have tried the sand-filled ant farms with dismal spills that freed too many of the inhabitants. The AntWorks home is filled with a blue gel-like substance that provides both nourishment and liquid to the ants. Accompanying literature explains that this gel was developed by NASA for experiments carried out on the Space Shuttle. One of the nicest features is that this gel is translucent, allowing observers to see completely through the tunnels. An optional illuminator is a nice addition which makes an interesting night light, but we thought that it wasn't necessary.

Ants are not included with the kit. You can either catch your own or mail in the enclosed coupon. We opted for the mail-order ants, and that boosted interest in the project for our little ones who love to receive mail. Once the ants are added to their home, the only maintenance that is needed is opening the top for a few seconds a week to allow fresh air to enter. Occasionally you will need to remove a dead ant, but our industrious insects buried their fallen comrades deep in the gel in sealed chambers. It was incredible to observe! This kit, combined with a few books from the library and a couple of diagrams and coloring pages downloaded from the Internet, provided a wonderful investigation into the life of ants for our elementary school-aged students.

Archimedes, the reknowned ancient Greek Scientist and Mathematician, had an enormous impact on all science and math since his time. This is his story, simply and even humorously told. The reader is introduced to many important concepts discovered and used by Archimedes including the lever, the pulley and his famous discoveries involving water displacement. (Numerous black and white drawings aid immensely in understanding these concepts). I love books which take concepts that have been made over-complex by modern textbooks and show how they are simple enough to be understood by children. Particularly interesting is the chapter entitled "The War Machines of Archimedes" which relates the story of his defense of Sicily by the use of Science: machines which hurled stones at the enemy and carefully designed mirrors which reflected sunlight on the enemy ships so intensely that they caught fire.Homeschoolers will appreciate Laura Berquist's helpful hints (in the introduction) for incorporating this book into your own curriculum. Keep in mind that this isn't just a Science book - it's an appropriate addition to the study of Ancient Greece and a Math Supplement as well. The complete index is useful for referring to particular topics

Reading Level: Ages 9-12

The Art of Construction (originally published in 1979 under the title Building: The Fight Against Gravity) is one of the finest examples of books that help children understand principles of science as applied to real life situations - in particular buildings and making sure that they stay up in spite of gravity and natural disasters.

Children are introduced to important concepts like "tension" and "compression" with simple hands on exercises to help understand and remember them. Most chapters include a somewhat-more-involved construction project to teach these principles (and have a lot of fun in the process). Numerous illustrations make concepts and clearer and aid in understanding the building projects.

The text is very engaging and easy-to-understand. We've found it ideal as a read-aloud with a group. Our co-op has been using it somewhere in the 2nd to 4th grade range, although it could certainly used by much older students (all the way through high school would be reasonable). The engineer dads in our co-op have been very impressed with the book and the concepts the children study.

The chapter titles are as follows (and give you a little glimpse of the content and style):

• From Cave to Skyscraper
• Building a Tent
• What is a Beam?
• What do We Build Structures With?
• The Floor of Your Room
• A Steel Frame...Made Out of Paper
• The Part of the Building You Don't See
• What Tornadoes, Earthquakes and Changes in Temperature Can Do
• How to Fight Tornadoes and Earthquakes
• Ropes and Cables
• Sticks and Stones
• Strings and Sticks
• Shape and Strength
• Barrels, Dishes, Butterflies, Bicycles Wheels and Eggs
• Balloons...and Back to the Tent

Here are a few random sample paragraphs to give you a sense of the style and substance:

"If you had one of your friends put your hands on each other's shoulders and move your feet away from each other, you will become a full arch and feel compressed by each other's weight. But if your shoes slip on the floor and you begin to slide apart, the arch will collapse. Its ends must be firmly anchored to prevent it from spreading apart." (pg. 15)

"The best way to understand how the frame of a building works is to build one. A good model of a steel frame can be built with paper, provided we first build the separate elements of the frame: the columns, the beams, and the floors. A column should not take too much floor room, but must be strong enough to carry the compressive loads without buckling under them. A column buckles, that is, bends under compression along its axis, if it is too thin. Take a plastic ruler, stand it up, and push downward on it: there comes a point when the ruler will bend out." (page 39)

"The purpose of a building's structure is to guarantee that the building will stand up under all the loads and forces acting on it: the weights, the pressure of the wind, the forces due to temperature changes, and, possibly, the shaking caused by earthquakes. The builders want to make sure that the building will not collapse, and they hope it will not even be damaged, since in the first case it may kill people and in the second it may be costly to repair. They also want to make sure that the building will not move around. If a house were to slide down the slope of the hill it is built on, or if a skyscraper were to be toppled by the wind, the buildings would have failed their purpose, even if their structures might sometimes ed up undamaged." (page 57)

This is one of the books that I want to be sure each of my children have a chance to study sometime during their school years. Highly recommended!

Subtitled "101 Easy Experiments that Really Work", this book is one in a series that is very popular with homeschoolers (and understandably so). The book covers seven major topics - Planets, Space Movement, The Sun, The Moon, The Stars, Space Instruments and Space/Space Travel. Each experiment uses simple experiments and explains (briefly) the purpose, the procedure, the expected result and a brief but very understandable explanation of why it happened. Black and white sketches illustrate each experiment as well. To give you an idea of the kind of material that is covered, here are a few of the experiment descriptions/purposes (out of 101 total) - "To determine how color affects a planet's surface temperature", "To demonstrate a method of proving that the Earth rotates", "To determine why planets move smoothly around the Sun", "To simulate aimng a spacecraft for the Moon", "To determine why stars appear to rotate", "To determine why radio wave receivers are curved". I found the "why" segments of each experiment helpful background reading for me to brush up on my science knowledge.

A nice picture book which introduces basic facts about whales and what they are: mammals rather than fish. Includes nice pictures (with some beautiful scenery) and informative text.
