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 earth science experiments, kids learn how crystals and metamorphic and sedimentary rocks form, why seismic waves move more slowly through sand, the effect of rain on hills with and without ground cover, the effect of acid on statues, and how freezing water causes rock movement. They will also determine and demonstrate how rain affects topsoil, what amount of pressure is required to fold the Earth s crust,...

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 chemistry experiments, kids learn how to measure the volume of melted snow, determine the weight of water, and demonstrate the effect that cold temperatures have on air density. They will also demonstrate how the density of different liquids varies, construct a hydrometer, demonstrate the cohesive force of water, and show how a chemical reaction can create heat. Featuring color illustrations and safe, simple...

In a series of fun and involving hands-on biology experiments, kids learn why plants seek light, how to grow plants from carrot tops, how water protects plants from freezing temperatures, why earthworms surface during a heavy rain, and why camels can live in the desert for weeks without drinking water. They will also determine and demonstrate the effect temperature has on the growth of bacteria, whether or not the light from fireflies gives off heat,...

In a series of fun and involving hands-on chemistry experiments, kids learn how and why a volcano erupts, why there are holes in bread slices, why pennies turn green, how to separate milk into its solid and liquid parts, and how to grow fluffy white crystals. They will also determine and demonstrate how air is cleaned by absorbent chemicals, how to change hydrogen peroxide into water and oxygen with the help of a potato, and how and why evaporation...

Shares science experiments that can be done at home that explain such physics concepts as static electricity, electromagnetism, and gravity.
