"Ninety-three million miles from Earth is a gigantic, white star - the sun. Why is the sun so important to life on Earth? Read to find out how the sun's energy is used on Earth.".
Describes the basic properties of materials, contrasting things that are hot and things that are cold, and includes photographs, a picture glossary, and a quiz.
A collection of ten illustrated science experiments that teaches about heat and electricity, covering temperature, conduction, expansion and contraction, the conservation of heat, food and energy, infrared radiation, and pressure.
Photographs and text provide a scientific introduction to heat, explaining what heat is, how it is made and measured, and the important balance between hot and cold for living things.
"Carefully leveled text and ... photographs introduce early readers to the concept of opposites by encouraging them to compare things that are hot with things that are cold. Includes tools for teachers, a table of contents, words to know, and an index"--Provided by publisher.
Using materials they can find in their home, students can learn the science behind temperature and heat by performing experiments that demonstrate the conduction of heat in solids, thermal conductivity of liquids and gases, the relationship between temperature and color, and other scientific principles.
