Why Kids Should Learn About the Ocean

The ocean is one of Earth’s most powerful teachers. It helps control our weather, provides the oxygen we breathe, and is home to millions of amazing plants and animals.
One of the reasons I began the CBGH journey was because my mother had just started volunteering at our local State Park, and she would come home with the saddest stories of vandalism and littering. It was clear the message to our youth to take care of their environment was lacking.
When kids learn about the ocean, they learn how everything in nature is connected — from tiny plankton to giant whales. Ocean science helps children build curiosity, empathy for living things, and respect for the planet. It also teaches responsibility, because understanding the ocean means learning how to protect it. When children explore ocean life, tides, habitats, and ecosystems, they don’t just learn science — they learn how to care for the world they live in.
These topics are particularly important to me. Please feel free to contact me with your favorite educational resources so I can share them here!

Ocean Food Chains & Food Webs
Grade Level: 2–5
Time: 20–30 minutes
Subjects: Science / Ecology / Environmental Awareness
Learning Objective
Students will understand what a food web is and how ocean plants and animals depend on each other for energy and survival.
Warm-Up Question (3 minutes)
Ask students:
- “Where do ocean animals get their food?”
- “What do you think tiny ocean plants eat?”
Explain that every living thing needs energy, and ocean food webs show how that energy moves from one organism to another.
Teach (Mini Lesson – 8 minutes)
A food web is a network of many food chains connected together. In the ocean, energy usually starts with sunlight.
- Producers: Tiny ocean plants called phytoplankton use sunlight to make their own food.
- Primary consumers: Small animals like zooplankton eat the phytoplankton.
- Secondary consumers: Small fish eat the zooplankton.
- Larger predators: Bigger fish, sharks, seals, or whales eat the smaller fish.
- Decomposers: Bacteria and other organisms break down dead plants and animals, returning nutrients to the ocean.
Explain:
“All ocean animals are connected. If one part of the food web changes, it can affect many other animals.”
Activity (10 minutes)
Build an Ocean Food Web
Give students cards or slips of paper labeled:
- Sun
- Phytoplankton
- Zooplankton
- Small fish
- Large fish
- Shark
- Decomposers
Have students stand in a circle and pass a string from one organism to the next to show who eats whom, forming a web.
Discuss:
- “What happens if phytoplankton disappear?”
- “Which animals would be affected?”
Quick Wrap-Up (3 minutes)
Key points:
- Ocean food webs show how energy moves through the ocean.
- Even the smallest organisms are important.
- Protecting oceans helps keep food webs balanced.
Extension (Optional)
Students draw their own ocean food web, including at least five organisms, arrows showing who eats whom, and one short sentence explaining why each organism is important.
Ocean food chain activities help students visualize how energy moves through marine ecosystems. These resources support lessons on producers, consumers, and decomposers while encouraging systems thinking and real-world connections.
