Description	Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water. From this, they understand that percent humidity is the percent saturation of the air. Resource contains vocabulary definitions and suggestions for assessment, extensions, and scaling for different levels of learners.
