Intro
Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Where does the energy in coal and oil come from?
The Big Idea
Coal and oil are burned to make power. But where did their energy come from in the first place? The answer goes back millions of years!
Ancient Life
Step one: ancient life. Coal and oil are made from the remains of ancient plants and tiny sea creatures that lived millions of years ago. Those living things captured sunlight to grow.
Buried
Step two: buried. When they died, they were buried. Heat and pressure slowly turned them into coal, oil, and natural gas.
Old Sunlight
Step three: old sunlight. So the energy we get from these fuels is old sunlight, stored for a very long time. We release it when we burn them.
A Closer Look
Let's take a closer look! Ancient swamps grew thick plants. Tiny sea creatures lived in oceans. Buried plants became coal. Buried sea life became oil.
Quick Facts
Quick facts! Fuels from ancient life are called fossil fuels. They took millions of years to form. Their energy began as sunlight. Remember, we release it when we burn them.
Think Like a Scientist
Now, think like a scientist! Draw a timeline. Start with ancient swamps and add the Sun at the beginning. End with a modern power plant. Add arrows to show the energy traveling through time. Tell a grown-up what you discover!
