What does the pH of lake water tell you?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. What does the pH of lake water tell you?

The Big Idea

Scientists check the pH of lakes! It's a special number. What does it tell you?

The Scale

Step one: The Scale. The pH scale runs from zero to fourteen. Water at seven is neutral, below seven is acidic, and above seven is basic.

Healthy Lakes

Step two: Healthy Lakes. Most lakes sit between about 6.5 and 8.5. If the pH gets too low, many animals like snails and some fish may struggle.

Rocks Matter

Step three: Rocks Matter. The rocks around a lake matter a lot. Limestone helps keep water balanced, while hard granite makes lakes more easily affected by acid.

A Closer Look

Let's take a closer look! Acidic. Neutral. Basic. Near seven.

Quick Facts

Quick facts! Pure rain is slightly acidic, around pH 5.6. Seven is neutral. Limestone balances water. Snails need good pH.

Think Like a Scientist

Now, think like a scientist! Pour a little of each liquid into cups. Dip pH paper in each. Match colors to the chart. Make a color chart of your results. Which was most acidic?

Outro

The pH scale runs from zero to fourteen, with seven neutral, below acidic, and above basic. Most lakes sit between about 6.5 and 8.5, and limestone helps keep them balanced, while granite lakes are more easily affected by acid. Science is amazing! Keep asking questions! The more you look around, the more wonders you will find, so keep your eyes open! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books. Available for purchase or download!
