While playing in her tree house, Jesse is intrigued by a falling sycamore seed that slowly spins to the ground. But when she sees acorns falling fast directly down to the ground, she must solve the riddle while learning about propellers and windmills and using technology to understand aerodynamics.
Simple text and illustrations introduce learning young readers to the science of aerodynamics, as a toddler in flight goggles explores the physics of how a bird flies.
"Engaging images accompany information about the science of flight. The combination of high-interest subject matter and narrative text is intended for students in grades 3 through 8"--Provided by publisher.
Explores how applied physics relates to the design and construction of roller coasters. Describes the physical dynamics of a roller coaster, explaining the role of potential and kinetic energy, friction, gravity, momentum and acceleration. Also introduces how the inertial effects, known as G forces, give roller coaster riders a thrilling experience.
Introduces basic facts about the properties of flight with instructions for related experiments and projects, and includes birds, bows and arrows, cannons, kites, hot air balloons, airships, gliders, helicopters, rockets, and many others.
