Close Encounters!: Systems & Interactions
Each book provides 20 thought-provoking scientific questions, investigations, and hands-on activities that explore the major topics in a theme-based science education: force and motion, patterns of change, systems and interactions, energy, and structure and function. There are fun "Did You Know" facts relating science to everyday life, "Explore Some More" follow-up activities, and applications of science to art, cooking, music, writing, and other subject areas.
