Introduces engineering concepts through twenty-five simple experiments that involve building several bridge and tunnel models.

Introduces civil engineering through twenty-five simple experiments that explore such concepts as Newton's third law of motion, buoyancy, and centrifugal force.

Presents thirty-five experiments designed to demonstrate the principles of engineering and construction, including a geodesic dome, magnetic spinner, hanging arch, crafty catapult, and trembling tower.

Profiles the systems that work together to keep urban areas running safely, discussing how cities have evolved since the first riverside settlements while outlining projects that explain facts about transportation, water systems, and architecture.

Children love challenges, especially ones that involve hands-on experimentation and friendly competition. Can they build a bridge using only pasta and glue, one that a toy car can drive both under and over, and is sturdy enough to carry a considerable weight? Can they construct a roller coaster from recycled cardboard tubes in which the marble car jumps a track to land safely at its final destination? And can they create a device to safely catch a...
