What is a scientific model?

A scientific model is a simplied representation of a more complex thing from the real world.

The model is designed to help demonstrate and understand the real-world thing better.

Models are never perfect recreations of the original.

The volcano pops up because there is a vertical

rod under the flexible pop-up crater that

moves upward a little each time the lava lever

is pushed down. This is because the other end

of the lava lever presses upward on a tth on

the vertical rod. A device called a ratchet keeps

the rod from falling down again even though

the lever resets each time. A spring pulls the

vertical rod downward while a small bar called

a pawl prevents the rod from falling downward.

The reset buon releases the pawl, letting the

vertical bar fall back down again and resetting

the crater.
