How Do a Sink and Faucet Work?

The spoken lesson

"A faucet, also called a tap, controls water. When the caregiver opens it, water flows into the sink basin. The basin catches the water, and the drain carries used water away through pipes. Some controls mix hot and cold water, so the caregiver always checks the temperature. Use a gentle stream and only the water you need. Do not climb into the sink, block the drain, or put toys inside it. Keep electrical things away from water. When finished, turn the faucet off and dry any water on the floor." DESIGN REQUIREMENTS: Use realistic water flow and accessible controls. Avoid water-wasting rewards, flooding animation, drain exploration, or child-controlled hot-water settings.
