    When it comes to hands-on projects, there seem to be two kinds of people in the world: those who want to assemble all the pieces necessary in the least expensive way and those who just want a complete kit so they don't have to run around and purchase supplies. If you're one of the latter, you will appreciate the wide range of equipment and tools included in this kit, as well as the comprehensive experiment guide. Like other kits from Thames & Kosmos, this one is well-produced and includes quality materials and a full-color experiment manual. The manual includes instructions for completing 100 experiments in the areas of physical science, earth and space science, and life science with specific chapters for experiments on: water, air, heat, sound, forces, magnets, electricity, electromagnetism, light and shadow, optical instruments, plants and animals, colors, human body, earth and sun, and chemistry. Looking through the manual, I recognize many experiments that are common middle-school fare such as weighing balloons with different amounts of air to show that air does have weight, making an atomizer that displays Bernoulli's Principle, changing water to ice to water vapor, observing that water expands when frozen, observing sound waves on the surface of water, swinging a cup of water to observe centrifugal force, building simple circuits, making an electromagnet, using mirrors to explore rays of light, making a camera obscura, dying carnations by placing them in colored water, listening to your heartbeat, building a sundial and many more that are often seen in curriculums or experiment books at this level. All special equipment is included, as are common objects like balloons, straws, modeling clay and black paper. Materials needed are listed at the beginning of each activity, with materials in the kit in regular font and additional materials needed in italics. Because so much is included here, materials that you provide are "basics" like water, batteries, flashlights, newspaper, and scissors. With the breadth of topics covered, this is one science kit that you'll use again and again. – Jess

    This might just be the most awesome volcano kit we carry! This kit includes a volcano mold, plaster, eruption powder, paint, paintbrush, booklets, and real specimens (geode, obsidian and pumice). Be creative and paint your volcano to make it personally yours, then make it erupt over and over with the erupting powder. The geode, obsidian and pumice are included so you can see and feel the different types of igneous rocks. You even get the bonus activity of breaking the geode to see what types of crystals are inside the rock. The Activity booklet includes ten fun puzzles - word search, dot-to-dot, word jumble, crossword, a very challenging volcano maze, and five more types of puzzles. The Adventure Guide includes information about volcanoes, structure of the earth, plate tectonics, etc. accompanied by colored photographs.

    This Discover with Dr. Cool Kit is just that – COOL! Great fun to paint, erupt, and learn about volcanoes and rocks. ~ Donna

    While robot kits are very entertaining and educational, they can be expensive. This kit is considerate in this regard, as it recycles its parts for up to 14 robots. Your kids can learn about solar power as an alternative energy source while putting together and playing with such creatures as Turtle-bot, Beetle-bot, Quadru-bot, and more. There are also two levels of complexity for the robots, some being simpler to put together, and some more challenging. Instructions are included for all 14 variations.

    Are you into robotics, but don't just want another nameless, bumbling, human-shaped thing? Perhaps you crave something that mimics nature's many wonders… like a Frilled Lizard robot. Well, amazingly, you've found that exact thing! Once assembled, this interactive robot can be set on two modes: "defense mode" and "pet mode". When set to "defense mode" this little guy will detect threats and respond accordingly by backing away, opening its mouth, puffing its frill, and running! On "pet mode" this reptile companion is a bit friendlier, albeit still cautious. It will still display its frill when feeling threatened, but when it feels safe it will follow you around adoringly. Although the recommended age range is 10 and up, it is worth noting that assembly is somewhat complex and requires time, patience, and vigilance. Instructions are diagrammed pictures, so little reading is required. However, there are some recommended tools not included. These are a diagonal cutter, a Phillips head screwdriver, a knife, and a hammer. In addition, the robot requires four AAA batteries (not included). The perfect gift for a robotics/model lover, a reptile lover, or someone looking to entertain their cats! Winner of Creative Child and Dr. Toy Awards in 2015.

      Skyscrapers stand tall without falling over. Bridges span great distances without collapsing. Introduce your inquisitive children to the forces of physics and structural elements that create magnificent structures. Beginning with small models, children will learn about basic structural elements including columns, beams, trusses, plates, arches, shells and catenary. Explore forces such as tension, compression, shear and torsion before moving into more complex models of trusses, roofs and small buildings. They will also experiment with different types of bridge constructions: truss, arch, suspension and cable-stayed bridges. Material strength and stiffness are investigated as they learn how structural engineers maximize safety and minimize cost at the risk of structural failure. Full color lab manual includes step by step illustrated directions to complete 20 experiments in 3 levels (easy, medium and hard), vocabulary definitions, “Did You Know” and “What’s Happening?” explanations, and more. Kit includes 323 pieces. Bring STEM alive to your children with this quality Thames & Kosmos experiment kit! ~ Deanne

In a separate bag are the screws, shafts, o-rings, and other mechanical items needed. You will need to provide a few tools to help with assembly – a diagonal cutter, screwdriver (small Phillips head), hammer, scissors, ruler, tissue paper, and permanent marker. The assembly & instruction manual is 48 pages of step-by-step, numbered illustrations with explanations. There are even a couple of pages of trouble-shooting suggestions, just in case. The finished product can then be hand-pumped full of air for the power to go a distance of up to 50 meters.
