Once upon a time, in a magical intertidal zone, lived a group of invertebrates who had to adapt to the changing tides. One day, a big, mean predator came to their neighborhood, scaring all the little creatures.

But then, a clever worm named Wriggle came up with a plan. He told his friends to use the power of gravity and rotation to their advantage. They would attach themselves to rocks and algae, becoming mobile and hard to catch!

At high spring tides, they would spin around like crazy, making it impossible for the predator to grab them. When the tide was low, during the neap tide, they would stick tight to the substrate, hiding from the hungry creature.

The predator soon gave up trying to catch them, and Wriggle and his friends were safe once again. They all lived happily ever after, adapting to the changing tides and having fun spinning and sticking to the substrate. The end!

Reflections

1. What did Wriggle and his friends have to do to protect themselves from the predator?
2. How did they use the power of gravity and rotation to their advantage?
3. What happened at high spring tides and during neap tides?
4. Why did the predator eventually give up trying to catch them?
5. What is the intertidal zone and what kind of creatures live there?
