In a series of fun and involving hands-on chemistry experiments, kids observe the effect of molecular motion, try to inflate a balloon inside of a bottle, demonstrate the cleaning of water by capillary action, discover how detergent causes other molecules to move, and make water appear to boil with only the touch of a finger. They will also demonstrate how salt makes it harder for water to freeze, learn how to grow salt crystals and how to produce an elastic material, and observe liquids that will and will not mix together. Featuring color illustrations and safe, simple step-by-step instructions, Janice VanCleave again shows just how much fun science can be.

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 takes away heat.

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.

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 velocity.

In a series of fun and involving hands-on biology experiments, kids observe the effect of osmosis on a raisin, demonstrate how leaves and stems can act like a straw, determine which side of a plant leaf takes in gases, demonstrate the loss of moisture from leaves, and discover the effects of gravity on plant growth. They will also determine the direction of winding plants, how shade affects plant growth, how plants grow toward light, and the effect of temperature on seed growth.
