Beskrivelse
This series introduces simple science topics using everyday objects and situations that readers can recognize in the world around them. The four titles cover different aspects of light, forces, magnetism and sound. This title looks at sound: how sounds are made, how they travel, how we hear them, what makes a sound high or low, loud or soft.
