The Yeerks have decided to try a little experiment. They've decided that if they can develop a way to make people more "willing" to be infested, they can speed up Earth's invasion. So the Yeerks try to invent a substance that will take away the human ability to make a decision. A substance that will eliminate free will. Now the Animorphs are not only faced with trying to slow down the Yeerks' invasion, but they also have to put an end to the genetic testing on a small group of humans. This time there's only one chance to stop the Yeerks. And if anything goes wrong, it's all over.

Plants have roots, stems, leaves, and sometimes flowers. Each part of a plant does a special job. But do you know what a stem does? Or how different seeds travel away from their parent plants? Let's experiment to find out! Simple step-by-step instructions help listeners explore science concepts and analyze information.

A plant can form fruit and seeds when it is pollinated. Animals and wind help spread pollen from one plant to another. But do you know how insects pick up pollen from flowers? Or how each part of a flower helps pollination? Let's experiment to find out! Simple step-by-step instructions help listeners explore science concepts and analyze information.
