Provides step-by-step instructions for performing experiments designed to answer such questions about the weather as what makes it rain, how do scientists measure air pressure, and how does temperature affect air movement.
Describes experiments that can be performed with plants in order to learn about their properties, including whether roots grow before stems, the importance of light, and how plants drink water.
Describes experiments that can be performed using solar energy in order to learn about its properties, including how different colors absorb sunlight, if it cleans dirty water, and whether it can cook food.
Describes experiments that can be performed with seeds in order to learn about their properties such as how water temperature affects seeds, the direction roots grow, and the effect of talk on plant growth.
Presents experiments and activities that demonstrate the concepts and scientific principles of magnetism.
Simple text explores the principles of liquids, including melting, freezing, surface tension, and density.
Presents experiments demonstrating the basic scientific principles of water, including information on erosion, precipitation, and condensation.
