Soft-bound, 64 page book, 24 reproducible task cards, full teaching notes. Scrutinize how some liquids float upon or sink through others. How will a candle float among these layers? Study the physics by measuring mass, displacing volumes and calculating densities. Build spring balances to measure weight and buoyancy. Discover that immersed bodies are buoyed up with a force equal to the weight of the water they displace. Eureka!
