Why Does the Rainforest Smell Earthy and a Little Sweet?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why does the rainforest smell earthy and a little sweet?

The Big Idea

The rainforest smell comes from busy recycling. Fallen leaves, wood, and fruit are broken down by fungi and bacteria, which release smelly gases. Flowers and fruit add sweet smells to the mix.

Busy Recyclers

Step one: busy recyclers. Fungi and bacteria break down fallen leaves, wood, and fruit. As they work, they release gases that we can smell, so decay has a smell.

Earthy Geosmin

Step two: geosmin. One of those gases is called geosmin. It gives damp soil its earthy smell, and our noses are very good at detecting it.

Sweet Scents

Step three: sweet scents. Flowers and ripe fruit add sweet smells to the air, and animals follow them to a meal. Warm, wet air carries all these scents, so you can smell them from far away.

A Closer Look

Let's take a closer look at the smells! Fallen leaves slowly break down. Fungi and bacteria help to turn them into soil. Soil gives off that earthy smell. And flowers and fruit add the sweet part.

Quick Facts

Quick facts! People can smell geosmin at incredibly tiny amounts. Fungi and bacteria are nature's recyclers, working day and night. Warm, wet air carries scents far. Go outside after rain with a grown-up.

Think Like a Scientist

Now, think like a scientist! After it rains, step outside with a grown-up and take a gentle sniff of the air. Describe the smell in three words. Do not touch or taste the soil or plants. Then compare it with the smell on a dry day.
