What is table salt made of, and why does it look like tiny cubes?

Video · 1:48 · Crafty Clover explains, from A Million Whys Book 27

Table salt is made of sodium and chloride, joined as sodium chloride. In a crystal, sodium and chloride alternate in a cube-shaped lattice, like a three-dimensional checkerboard. As the crystals grow, their outer faces form flat squares, so each grain is a tiny cube. This is why salt crumbles into smaller cubes. Salt is safe in food.

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. What is table salt made of, and why does it look like tiny cubes?

The Big Idea

Look closely at table salt. Each grain is a tiny cube! Why is that?

Sodium Chloride

Step one: Sodium Chloride. Table salt is made of sodium and chloride, joined as sodium chloride. Salt is safe to eat in food.

Checkerboard

Step two: Checkerboard. In a crystal, sodium and chloride alternate in a cube-shaped lattice. It's like a three-dimensional checkerboard.

Tiny Cubes

Step three: Tiny Cubes. As the crystals grow, their outer faces form flat squares, so each grain is a tiny cube. That's why salt crumbles into smaller cubes.

A Closer Look

Let's take a closer look! Sodium is one part. Chloride is the other. They alternate. Cubes form.

Quick Facts

Quick facts! Chlorine gas is poisonous, but when it joins sodium in salt, it becomes something different, which we eat every day. A 3D checker board. Grains are cubes. Salt is safe in food.

Think Like a Scientist

Now, think like a scientist! Cut squares from two colors of paper. Make a checkerboard layer. Make another layer, switching colors. Stack them up. You've made a salt model!

Outro

Table salt is sodium chloride. Sodium and chloride alternate in a cube-shaped lattice like a 3D checkerboard, so each grain grows into a tiny cube with flat square faces. Science is amazing! Remember, every big discovery starts with a small question. Keep looking, keep learning, and keep asking why! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books.
