If Forest School feels overwhelming, start small.
You do not need to visit the coast to explore seas and oceans outdoors. You can use your playground, school field, garden, tuff tray area or outdoor space to bring the seaside to life.
Try:
- A 10-minute sea creature movement game
- A simple ocean loose-parts challenge
- One outdoor question, such as: “How can we protect the sea?”
Forest School-inspired learning works best when children have time to move, imagine, build, talk and explore.

Create a Mini Ocean Habitat
Ask children to work in pairs or small groups to create a mini ocean habitat using natural materials.
They could use:
- leaves for seaweed
- stones for rock pools
- sticks for driftwood
- shells if you have them
- blue fabric, chalk or hoops to mark the sea
- cones or pebbles for sea creatures
Time: 20–30 minutes
Prep: Low
You need: Natural loose parts, chalk, hoops or fabric
Learning: Habitats, marine life, vocabulary, teamwork, science and creativity
Encourage children to explain:
- Which creatures live here?
- What do they need to survive?
- How is your ocean habitat protected?
- What might harm it?
This gives children a simple, hands-on way to explore oceans, habitats and environmental care outdoors.
Forest School Seas and Oceans Ideas
Here are a few simple ways to link seas and oceans to outdoor learning.
1. Rock Pool Explorer
Create pretend rock pools using hoops, chalk circles or shallow trays.
Children can add natural materials and imagine which creatures might live there, such as:
- crabs
- starfish
- limpets
- fish
- seaweed
- anemones
Children can then become marine biologists and describe what they have discovered.
This links beautifully to science, speaking and listening, habitats and observation skills.
2. Ocean Rescue Mission
Set up a simple outdoor challenge where children rescue sea creatures from “pollution.”
Use clean, safe items such as paper, fabric scraps, bottle tops or classroom recycling to represent rubbish.
Children can sort the items into:
- things that belong in nature
- things that need recycling
- things that could harm animals
This helps children understand ocean pollution in a practical, age-appropriate way.
3. Move Like the Sea
Invite children to move around the outdoor space like different parts of the ocean.
They could move like:
- rolling waves
- tiny fish
- a slow turtle
- a drifting jellyfish
- a scuttling crab
- seaweed swaying in the water
This is a lovely way to support sensory learning, vocabulary, physical development and imaginative play.
