Ocean Heroes KS2 Wonderful worms

A fun, hands-on lesson that introduces classes to sediment, the ocean equivalent of soil. This practical lesson shows how important worms are for the health of the seabed.

During this lesson, students will:

• Become seabed scientists: Guide your young researchers as they uncover the secrets of marine sediment - the ocean’s equivalent of soil. They’ll learn why it’s crucial for ocean life.
• Meet the unsung heroes of the sea: Introduce your class to the fascinating world of marine worms. Through fun, hands-on activities, students will discover how these humble creatures are the hardworking gardeners of the seabed.
• Get their hands dirty (in the best way): Engage in a messy but memorable practical activity that demonstrates how worms transform the seabed.
• Investigate human impacts: Challenge your class to think critically about how human activities affect the seabed. They’ll develop environmental awareness and problem-solving skills as they consider ways to protect these crucial habitats.

This lesson brilliantly extends the KS2 Science curriculum, introducing marine sediments as a natural progression from the study of rocks and soils. It also touches on key Geography concepts.

By the end of this lesson, your students will:

• Confidently describe the features and location of shallow sea habitats
• Demonstrate understanding of how ocean sediment forms and its importance
• Explain the crucial role of worms in creating a healthy seabed ecosystem
• Show improved critical thinking skills when considering human impacts on marine environments

Science KS2
• Marine sediments have yet to feature directly in the National Curriculum, and this lesson can be used as an extension to the study of rocks and soils
• This lesson also introduces the relationship between soils and sediments and the animal life that can make them more suited to other life
• Recognise that environments can change and that this can sometimes pose dangers to living things
