Condensation is crucial for returning evaporated water to Earth. When water vapor cools in the atmosphere, it transforms into liquid droplets, forming clouds. Eventually, these droplets combine and fall as precipitation, replenishing water sources.
Acting out the water cycle involves students role-playing stages like evaporation, condensation, precipitation, and collection. This interactive activity helps illustrate how water moves through its cycle, making the concept engaging and memorable.
Blowing air over a wet hand cools it more because evaporation of water absorbs heat, while the dry hand doesn’t benefit from this process. Evaporation requires heat, which cools the wet surface.
Leaving sludge in heaps allows excess water to drain out, reducing its weight and volume. This makes transportation cheaper and easier, while letting it partially decompose improves safety and reduces handling risks.
