In a series of fun and involving hands-on earth science experiments, kids learn why the Earth bulges at the equator, demonstrate the movement of the Earth's axis, determine how the composition of the Earth affects its motion, and replicate the cause of the day-and-night cycle. They will also determine why the sky is not dark as soon as the Sun sinks below the horizon, learn how salt beds are formed, demonstrate how air takes up space, observe the...

Astronomy enthusiasts, science gurus, and all curious minds, are provided nearly two dozen experiments that will certainly garner multiple science-fair awards. Each experiment exhibits clear, safe instructions with descriptive text and detailed photography. They will see why light bends in a medium, how to determine the size of the sun, and how gravity works, as they practice the experiments. As hands-on learning tools, experiments are not only educational,...

Young scientists will learn the power of physics when they make their own lemon batteries, demonstrate centrifugal force, and exhibit how sound energy travels. They will identify magnetic poles, learn what the best conductor for heat is, and even determine why eggs don't break beneath their bird guardians. Color illustrations and safe, simple step-by-step instructions will guide readers through this collection of twenty-four physics experiments from...

Students, parents, and teachers will enjoy the biology concepts, ideas, theories, and activities provided in this guide to science experiments. Budding biologists and biology enthusiasts alike will find a science fair worthy project in this exciting volume. With easy-to-follow instructions and full-color photographs, readers are just a few steps away from science fair success.

In a series of fun and involving hands-on astronomy experiments, kids learn how distance from the sun affects atmospheric temperature, why the Earth is called the "Blue Planet," why Jupiter's ring shines, and how to reproduce Mars' red soil and Jupiter's stormy red spot. They will also determine why radio wave receivers are curved, how radio waves are sent around the Earth via satellite, how satellites enter into orbit, and how rockets achieve escape...

In a series of fun and involving hands-on earth science experiments, kids learn why the atmosphere is thinner at the Earth's poles, how a lunar eclipse can indicate Earth's shape, and how to create a Foucault's pendulum. They will also demonstrate continental drift, learn how to model meridians and parallels, and create a topographic map and a 3D model of a mountain. Featuring color illustrations and safe, simple step-by-step instructions, Janice...

In a series of fun and involving hands-on astronomy experiments, kids learn how the Sun's rays affect the visibility of Venus, determine the difference between local sun time and clock time, and observe and chart the phases of the Moon. They will also demonstrate why only one side of the Moon is visible from the Earth, make a model of the celestial sphere, and create a model of a multistage rocket. Featuring color illustrations and safe, simple step-by-step...

In a series of fun and involving hands-on physics experiments, kids charge an object with static electricity, demonstrate how static charges produce sound, use magnetic force to suspend a paper airplane, determine that objects in water have a different weight than they do in air, and learn how a substance's buoyancy can be changed. They will also determine if shape determines the strength of an object, learn the effect that an object's center of gravity...

In this series of fun and involving hands-on earth science experiments, students will learn how atoms and molecules arrange themselves in minerals, how global warming could raise sea levels, and even how rocks melt. They will also create their own instrument to measure humidity, grow crystals, and demonstrate how soil texture affects the amount of air in soil. From lake bottoms to icebergs to hurricanes, readers will engage with this fun installment...
