    Explore the workings of a jet engine without the toxic fuel smell! Detailed instructions provide all you need to create this working model jet engine. While it won't fly throughout the house (thankfully!), children will be able to control the thrust and turbine speed from the display stand ("Testing Lab".) While recommended for ages 8 and up, my impression is that middle school age children may require adult assistance. Completed jet engine measures approximately 8" x 12". Includes impressive 35"x12" poster of a U.S. Air Force SR-71 Blackbird with detailed information on the Blackbird, basic engine terms, how a jet engine works, and jet engine components. Requires 4 "AA" (1.5V) batteries and screwdriver (not included). ~ Deanne

    Even if you don't live anywhere near the ocean, your kids can still explore the amazing properties of earth's great watery expanse, along with the unique plants and animals that inhabit it. This Kids Can! activity book introduces major ocean and ocean life concepts, followed up with simple hands-on investigations that kids can perform, often with minimal adult help. The text is written in a clear, easy-to-read style, broken up by subject headings, more like a magazine format than in textbook form, and accompanied by playful cartoons of children and sea animals. The investigations use commonly found items, and are typically simple, easy to perform (they obviously know it's hard to keep a kid's interest for very long!) and complement the preceding text to reinforce concepts so the kids can "see" it, rather than just learn about it. For instance, after learning about different shapes and types of fish, they make fish models of clay on a string, and pull them through the water to see which shape creates the least resistance, and then fill up small balloons, with air, oil and water, imitating fish with air bladders, fish without, and sharks to see which has the greatest and least buoyancy when it comes to swimming. Kids love taking an investigative approach to science, why not throw in some ocean books from the library, and make it a science unit?

    (description by publisher - stay tuned for our own!) Learn how plants germinate from seeds, how they grow, what they need to grow, what they produce, and how their roots, stems, and leaves work. 16-page color guidebook.

    Almost every science course reviews the work of famous scientists and the groundbreaking discoveries that they made. Reading about their work is good, but actually performing the same experiments that these scientists did would be so much more meaningful. With this Thames & Kosmos kit, you can do just that, without the hassle of assembling all the materials yourself. Build a telescope like Johannes Kepler, a spectroscope like Joseph von Fraunhofer, a phonograph like Thomas Edison, a steam engine like James Watt – in all, 100 experiments and discoveries covering the work of 140 scientists and inventors. Chapters are included on: Light, Colors, and Sound; Heat, Steam, and Engines; Magnetism and Electricity; Communication and Microelectronics; Forces; Life; Atoms and Molecules; Stars and Planets; and the Periodic Table. In addition to the models mentioned above, students will also make or study a battery, telegraph, radio, airplane, star map, and many others. All components needed for all the experiments are included in the kit, except a 9-volt battery to power some of the experiments. The 94-page Experiment Manual is an excellent teaching tool in itself; in addition to giving verbal and visual instructions for all experiments, lots of historical information and "Did you know …" tidbits are included. The manual is full-color and contemporary, but includes period photographs and drawings that resemble a lab journal from the past. Over the years, you could be pulling this kit off the science shelf again and again, unless your kids decide to do all of the experiments right away!

    Introduce children to the power of the sun! This kit contains everything necessary to build a working solar powered rover. Once built, the rover will drive forward and backward (no steering mechanism). Children will learn the intrinsic power of the sun as they see, firsthand, the rover in action. Backup power generator included for extended play. While designed for older children to complete independently, younger children will enjoy the experience with an older sibling or parent. This truly is environmental science for all ages! ~ Deanne

    Whether you are passionate about vehicles or just looking for an introduction to building with an Erector® set, this kit is for you. With over 230 pieces and 20 moving machines to build, this set has basic models for beginners as well as more challenging moving models that use the 3v motor (included). Unlike Erector® sets of old, powder-coated and galvanized chrome pieces give the models a stunning look and a rewarding feel when completed. It is one thing to know "righty tighty, lefty loosey"; it is another to use it dozens of times to create something that looks and works great!

    This model kit allows your young dinosaur enthusiast to take their passion to the next level! Children will experience the thrill of being a paleontologist as they construct the 15" T-Rex layer by layer, from squishy organs to the clear plastic body shell. Dinosaur includes 5 squishy organs (heart, intestines, lungs, stomach, and tongue), 9 plastic bones and muscles, and clear outer shell pieces. Once completed, your dinosaur can be displayed on the plastic 'rock' stand. Kit also includes The Mighty Rex, a 24-pg. book from Dennis Schatz, a noted scientist from Seattle's Pacific Science Center. Evolutionary content. Detailed instructions included. ~ Deanne

    A while back, Janine, Stephen and I did a science lab where we isolated onion DNA, and it was awesome - we were all in shock (first of all, that the experiment worked!), and it was incredibly cool to see the tiny strands! And then we discovered this awesome lab, which does a much better job at introducing students to DNA and really understanding it before they isolate fruit DNA - and do some very cool things with bacterial DNA! A 40-page book in the kit introduces kids to DNA and its importance. Use of diagrams and illustrations is excellent throughout the book. Then kids will jump right into extracting DNA from a kiwi, strawberry, or onion. The step-by-step instructions are both illustrated and printed, and are very easy to follow. After the dramatic results are seen, kids can observe the DNA in the test tube, and even poke it around a little bit to see what it's like. After the excitement is over, the author explains why the experiment worked, and why you can see the DNA. Now that they're hooked, students are introduced to the basics of DNA, including the four bases, the "twisted ladder" model, the history of DNA discovery, DNA duplication, how four DNA bases code for 20 amino acids, how DNA is divided into chromosomes, and more! The included equipment contains both cardstock "chromosome" halves as well as a mini-DNA model kit, so that kids can play with both of these ideas hands-on. After they have a good understanding of what DNA is and what it does, they're ready to do the last big experiment - extract their own DNA! The sample is collected from inside the cheek, and once they have isolated the DNA they can keep it in the freezer, or use it to make their own "forgery-proof" ink. This experiment takes the place of the one previously included, where young experimenters would mix plasmids into bacteria to create glowing colonies. While this is unfortunate, kids will likely enjoy isolating their own DNA as well. The lab equipment is included here; the only things you will need to supply are some household and food items. - Jess
