Lighthearted and visually interesting due to varied font size, many sidebars, colorful captions, and diagrams and illustrations that work together seamlessly to illuminate the texts, this accessible series packs in a lot of information. Whether discussing distillation and chromatography in Mixtures and Solutions, electromagnetic waves in Forms of Energy, pitch and frequency in Light and Sound, or the invention of Kevlar in Inventions and Investigations, this series will be compelling reading for both browsers and science buffs. Each title includes several experiments or activities, a summary of topics covered or a summary quiz, and suggestions for further research. Information is clearly presented and flows smoothly from subject to subject. A treasure trove of fascinating facts.
