    Kids love it, students will find it helpful, and even adults get caught up in the excitement of its construction and operation. This see-through working model of a four-cylinder engine has that much detail. And the beauty of it is, you wont get covered in oil working on this engine and it doesnt cost thousands of dollars to fix if something goes wrong! All of the parts needed in building the engine to get the valves rocking, the spark plugs firing, and the pistons driving the crankshaft are included, except for the two "AA" size batteries. Even the screwdriver is supplied. With over 100 working parts, this is a high quality engine model. ~ Zach

    Here in the Midwest, we see windmill farms popping up all over the place, trying to take advantage of the wind over our flat topography. And as wind is more and more often promoted as a green source of energy, it is worth taking a look into to see the benefits and challenges presented by harnessing the power of the wind. This excellent kit by Thames & Kosmos helps you do just that with a mix of their sturdy plastic physics parts and a full-color, 35-page experiment guide with 20 activities. Besides presenting the experiments, the guide also provides information on air currents, windmill designs of today and yesterday, how wind can perform work, the power formula for wind, apparent wind, turbulence, lift and resistance. In the experiments, you will build a wind power plant, then use it to lift a weight, try different wing shapes, calculate the rotation speed and speed ratio, and use the windmill to power a light, recharge a battery and as a fan. Who knows? If you live in a location with a lot of wind, you might just go on to build your own windmill generator for your home! Jess

    Sure, using a metal detector is fun. But what about building one? It may not be the steel-framed, $100 model, but constructing the detector it is nevertheless a learning experience. This kit contains everything you need to learn how a metal detector works and build your own working model ~ Stephen

    Heres a real hands-on opportunity with a useful outcome - build this inexpensive microscope that really works. Using the pieces in the box and the step-by-step illustrations in the included guide book, students can easily assemble this 300X, plastic microscope. I assembled this sitting at my desk and used it to view some prepared slides that I keep in my desk drawer. It was just as easy to take it apart to rebuild again later. There are instructions for seven activities: take a look at seasonings found in your kitchen, flower pollen, potato starch, and more. You can even read a short section on the history of the microscope. ~ Donna

    Break out the scissors, tape, paste and paper and make a stomach book, 3-D skeleton, a growing-tooth movie, a cardboard spinal column, manipulative eye, and more! The book begins with a study of the sense organs: tongue, eye, ear, nose, and skin. Building models of each helps children understand how they work. The rest of the book is on body systems: skeletal, digestive, respiratory, circulatory, excretory, and muscular. Building models of the systems and some of their components after discussing them and performing some illustrative activities provides for active learning. Model patterns used are reproducible, so everyone can join in.

    Let your young scientists explore the earth with 60 activities in the areas of the earths structure, fossils, rocks & minerals, crystals & gems, and earthquakes & volcanoes. Dont let the smaller 9x 7 size fool you; this book is over 180 pages of information and fun. Each of the five chapters follows the same format. A cute little poem (corny at times) begins the chapter and is then followed by a list of the activities and new words you might encounter (along with definitions). Dynamic Earth offers bulleted information on that specific topic and then a number of activities is presented along with materials lists, instructions and illustrations (black & white) where needed. You will get to play Earth Trivia, make an earth spinner, take a core sample of a cream-filled cupcake, use tostada shells to model the continents, play Continent Bingo, make fossils, start a fossil collection, grow crystals and much more. Youll find most items needed for the activities around your house, and there are some reproducible pages for some of the other activities. The back of the book offers a few (minimal) suggestions for additional resources, but you will probably be able to find some good ones at your local library. There is also a suggestion for purchasing fossil, rock, and gem specimens but you can let your child collect rocks while playing outside or find your own sources for purchasing (We carry quite a variety).

    Use this book as a unit study about earth science or as supplemental hands-on for your curriculum, either way you will have a lot of fun as you learn about the earth. ~ Donna

    Spool knitting is an easy, fun skill for young kids to master and it allows them to create their own cute little creations. The instructions describe (in a few simple steps) how to spool knit using the included plastic spool knitter. Diagrams accompany the directions, and after just a few minutes of acquainting themselves with the process, kids should be ready to go. The rest of the instructions detail how to make specific critters using the included yarn and spool knitter. A plastic needle and craft stick are also included, along with everything you need to fashion one of each creation shown. Before you know it, your child will have a whole zoo!
