🌦️ Weather and Water Power
Rain
More rain means fuller rivers and lakes, so dams can make more electricity.
Droughts
When it doesn't rain for a long time, lakes shrink. Dams have to save water and make less power.
Snowmelt
In spring, snow on the mountains melts and fills the rivers. Many dams make the most power in spring!
Floods
After huge storms, dams can hold back extra water and let it out slowly, which helps protect towns from floods.
🧪 Try It at Home with a grown-up
Spoon water wheel
With a grown-up, push plastic spoons into the edge of a paper plate and put a pencil through the middle. Hold it under a gently running tap. Watch it spin!
Rain gauge
Put a straight-sided clear jar outside. After it rains, measure the water with a ruler. That's how much rain fell. Compare rainy weeks and dry weeks!
Safety first
Rivers and water near dams can be fast and deep, even when they look calm. Never play near them, and never in flood water. Stay with a grown-up.
