Getting from one place to another sounds easy if you are on a straight piece of land, but what if you have to get over—or under—a body of water or a deep gorge? Build a bridge! Bridges are the great connectors. They allow us to travel the twists and turns, highs and lows, ins and out of every geographic feature in our world. Explore Bridges! With 25 Great Projects introduces readers ages 7 to 10 to the concepts and vocabulary of bridge construction through the lenses of history, science, engineering, math, and technology. From the Golden Gate Bridge in San Francisco to the Tower Bridge in London, bridges are a huge part of our life. But how are these amazing structures built? What forces keep it standing? What might cause it to fall down? And who decides which type of bridge to use? In Explore Bridges, readers discover how these extraordinary feats of engineering are created, and apply what they have learned to hands-on, critical-thinking activities that include building different types of bridges, such as truss, cantilever, and suspension bridges, out of different materials and modeling different types of supports. They examine the natural forces that affect structure selection and appearance, and also learn about the types of support required for each. Trivia, cartoon illustrations, links to online videos and other sources, and clear diagrams round out this book and make it fun and interesting for class discussions. Following the guidelines set forth in the NGSS/NSTA engineering and design standards, teachers can feel comfortable using this book as a guide for targeted learning in their classrooms.
Did you know that hydropower supplies 16 percent of all electricity worldwide? And there are more than 57,000 big dams around the world! Canals and Dams! With 25 Science Projects for Kids invites kids ages 7 though 10 to investigate the waterways that help the world run! Through fun facts and engaging content, readers explore record-breaking structures such as the Panama Canal and Hoover Dam. They also learn about the physics that make canals and dams work! Elementary-aged kids discover how hundreds of years of innovation created the canals and dams we know today and how this technology affects people and the environment. Discover how one dam can both supply electricity to entire cities, and flood entire towns, and how one canal can cut trade routes in half! Through 25 hands-on projects that use materials found around the house or classroom, kids will explore the mechanisms that make canals and dams work. Engaging STEM projects and experiments, such as engineering a beaver dam and experimenting with water, help kids break down the small processes behind big structures! By combining science with fun facts, jokes, activities, and experiments, kids will have an exciting adventure exploring the world’s canals and dams, while links to primary sources offer ample opportunity for further student-led exploration. Canals and Dams! is part of a set of four Explore Engineering books. In the Explore Engineering series, readers ages 7 to 10 learn the physics behind the things they build: Why does a tower of blocks eventually fall? Why does a tunnel sometimes cave in? Through a series of focused, science-minded activities that require critical thinking paired with creative trial-and-error attempts at building, readers develop foundational understanding of the physics that guides the building and maintenance of bridges, canals, tunnels, and skyscrapers. Other titles in the Explore Engineering set include Bridges!, Tunnels!, and Skyscrapers!
Chockfull of fun and knowledge for inquisitive youngsters, a field guide for the science explorer on the go offers more than sixty hands-on experiments, from finding meteorites at the beach to whispering in their own ear.

Atoms and molecules are the basic building blocks of matter. Matter is every physical thing around us in the universe, including our own bodies! In Explore Atoms and Molecules! With 25 Great Projects , readers ages 7 to 10 investigate the structure of atoms and learn how atoms fit together to form molecules and materials. If everything is made out of atoms and molecules, why do people look different from dogs and doorknobs? In Explore Atoms and Molecules , readers discover that the characteristics of a material are determined by the way the atoms and molecules connect, and study how chemical reactions change these connections to create everything we know. This book discusses the elements on the periodic table and why they are grouped into families, encouraging the exploration of meaningful classification systems. States of matter and mixtures and compounds round out the exploration of atoms and molecules! This book supports the maker movement with lots of hands-on activities that illuminate the concepts of chemistry. Readers build 3-D models of molecules and create a periodic table guessing game. Fascinating sidebars offer opportunities for readers to connect the text with real-world science, and cartoon illustrations provide a fun foundation for learning.
Everything moves! Kids run around the playground, cars drive on the road, and balls fly through the air. What causes all this motion? Physics! Forces and motion rule the way everything moves through space. In Explore Forces and Motion! With 25 Great Projects , readers ages 7 through 10 discover that the push and pull of every object on the planet and in space depends on how a force acts upon it. Things float because of a force called buoyancy, we stick to the ground because of a force called gravity, and we make footprints in sand because of a force called pressure. Physics becomes accessible and interactive through activities such as a experimenting with a water cup drop, building a bridge, and spotting magnetic field lines. Simple machines such as levers, pulleys, and wedges are used as vehicles for discovery and comprehension of the foundational concepts of physical science. Using a theme familiar to everyonemotionthis book captures the imagination and encourages young readers to push, pull, twist, turn, and spin their way to learning about forces and motion.
Imagine a world without light. What would it be like? Dark, cold, and lifeless! In Explore Light and Optics! With 25 Great Projects , readers ages 7 through 10 find out why light is so important to our world. We use light to communicate. Because of light, there are natural phenomena such as rainbows and the auroras. And it's light that provides living things with the energy they need to exist. In Explore Light and Optics! , readers learn how light travels, how the eye works, and why we can see objects. They read about optical inventions that changed the world, including microscopes, telescopes, and cameras. Kids are introduced to modern inventions such as lasers, solar planes, and the hundreds of thousands of miles of fiber optics that make it possible to transmit data all over the world. Through projects ranging from making a spectroscope and concocting invisible ink to creating a periscope and experimenting with lenses, children discover how light can be bent, bounced, and broken. Fun facts, jokes, cartoon illustrations and links to online primary sources spark an interest in the fascinating role light plays in our lives from the sun shining overhead to the cellphone in our back pocket.
