What makes a growing crystal stop?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. What makes a growing crystal stop?

The Big Idea

Crystals can't grow forever. Something makes them stop. What is it?

Running Out

Step one: Running Out. A crystal stops growing when there is nothing left to add. The liquid may run out of dissolved material.

Other Reasons

Step two: Other Reasons. The temperature may change, or the crystal may bump into the wall or another crystal. Sometimes changing conditions even dissolve part of the crystal.

A Record

Step three: A Record. When the crystal is finished, it holds a record of the conditions in which it grew. Scientists read those clues.

A Closer Look

Let's take a closer look! Liquid runs out. Heat changes. Walls block it. Neighbors crowd it.

Quick Facts

Quick facts! Some crystals pause growing and start again later. Nothing left to add. Walls block growth. Crystals keep records.

Think Like a Scientist

Now, think like a scientist! Grow salt crystals on a dish. Check them every day. Notice when new ones stop forming. Watch as the water dries up. Write down what you see.

Outro

A crystal stops growing when there's nothing left to add, when the temperature changes, or when it bumps into a wall or another crystal. A finished crystal keeps a record of how it grew. Every crystal has a story. Even stopping is part of the story. Science is amazing! What will you discover next? Every question is a new adventure, so keep wondering and keep exploring with me!
