What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. How is an electric car charged, and where does that energy come from?

The Big Idea

An electric car has no gas tank. It runs on a big battery instead. But where does that energy come from?

Big Battery

Step one: big battery. An electric car stores energy in a large battery. You charge it by plugging it into an outlet or a charging station.

Many Sources

Step two: many sources. The electricity comes from the grid, which may be made from many sources. They include wind, solar, hydro, nuclear, and fuels.

Motor Wheels

Step three: the motor turns the wheels. An electric motor then turns the wheels. Electric motors waste less energy than gasoline engines, so more of the energy moves the car.

A Closer Look

Let's take a closer look! The charger fills the battery. The battery feeds the motor. The motor turns the wheels. Braking can put energy back.

Quick Facts

Quick facts! Electric cars can recover energy when braking. You can charge one at an outlet or a charging station. The grid has many power sources. Electric motors waste less energy than gasoline engines.

Think Like a Scientist

Now, think like a scientist! Draw the path of energy from a power plant to the wheels of an electric car. Then draw the path for a gasoline car. Compare the two paths. Which has more steps where energy can be lost? Keep asking why, and keep exploring!

Outro

An electric car runs on a big battery that is charged from the grid, and its motor wastes less energy than a gasoline engine. Science is amazing! What will you discover next?
