What happens to fish when water from a factory is much warmer than the lake?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. What happens to fish when water from a factory is much warmer than the lake?

The Big Idea

Some factories release warm water into lakes! That can be a problem. Why?

Warm Holds Less

Step one: Warm Holds Less. Warm water holds less oxygen than cold water. That's a big problem for fish that need lots of oxygen.

Heated Water

Step two: Heated Water. Factories, power plants, and hot paved areas can send heated water into a lake. Fish that need cold water can have trouble breathing, and warmth can also encourage algae.

Protecting Lakes

Step three: Protecting Lakes. Careful planning helps protect lakes. Cooling water before it's released and shading streams with trees both help.

A Closer Look

Let's take a closer look! Rises. Drops. Grows more. Cools streams.

Quick Facts

Quick facts! Trout and whitefish are especially sensitive to warm water. Warm water less oxygen. Pavement heats runoff. Trees shade streams.

Think Like a Scientist

Now, think like a scientist! With a grown-up, find a sunny puddle and a shady one. Measure each temperature. Write both down. Compare them. Which would trout like better?

Outro

Warm water holds less oxygen than cold water, so heated water from factories, power plants, or pavement can make it hard for cold-water fish like trout to breathe and can encourage algae. Cooling water first and shading streams helps. Science is amazing! The world is full of surprises. Keep asking big questions, and keep exploring with me!
