In this video, Richard Coward is going to teach you all about life cycles in the ocean. There are so many amazing creatures that live in the earth’s waters. Some are large and dangerous. Others are small and helpful. Some give birth to live young while others lay eggs.
Like all animals, fish need to survive and grow large enough to reproduce. Fish that make it to adulthood and to spawning time use a range of strategies to ensure successful reproduction. This video looks at the factors that go into keeping any sea species alive while examining the life cycles of sea stars, fish, sharks, and sea turtles.
This video satisfies the 3-LS1-1 requirement for third-grade science proficiency.
Students who demonstrate understanding can:
3-LS1-1. Develop models to describe that organisms have unique and diverse life cycles but all have in common birth, growth, reproduction, and death.
