Identifying Coastal Landforms: Beaches and DunesActivities & Teaching Strategies
Active learning works for this topic because children need to see, touch, and manipulate the materials that shape coastlines. Watching waves deposit sediment or feeling wind move sand makes abstract ideas about energy and deposition concrete and memorable.
Learning Objectives
- 1Compare the characteristics of sandy beaches and pebble beaches.
- 2Identify sand dunes and explain their location on a coastline.
- 3Describe the role of wind in forming sand dunes.
- 4Explain how vegetation, such as marram grass, helps to stabilize sand dunes.

Sorting Station: Beach Materials
Gather sand, pebbles, and shells in trays. Students sort items by size, shape, and smoothness, then predict how waves might form each beach type. Groups share findings on a class chart.
Prepare & details
What do you notice about the difference between a sandy beach and a pebble beach?
Facilitation Tip: During Sorting Station: Beach Materials, circulate and ask each group to predict which material would be found on a pebble beach before they touch it, linking their prior knowledge to new evidence.
Setup: Wall space or tables arranged around room perimeter
Materials: Large paper/poster boards, Markers, Sticky notes for feedback
Fan Model: Dune Building
Provide trays of dry sand and hairdryers on low settings as wind. Students blow sand to form dunes, noting how ridges grow and add grass clippings for stability. Observe and sketch changes.
Prepare & details
What are sand dunes and where do you find them?
Facilitation Tip: During Fan Model: Dune Building, challenge students to adjust the fan angle and distance to see how wind speed changes dune shape and height in real time.
Setup: Wall space or tables arranged around room perimeter
Materials: Large paper/poster boards, Markers, Sticky notes for feedback
Image Hunt: Coastal Map
Display UK coastal photos and maps. Pairs label beaches and dunes, discuss locations, and draw their own simple coast map showing features.
Prepare & details
What do you think makes sand dunes grow bigger over time?
Facilitation Tip: During Wave Simulation: Beach Formation, ask students to film the tray with a tablet so they can replay the slow action of waves sorting sediments.
Setup: Wall space or tables arranged around room perimeter
Materials: Large paper/poster boards, Markers, Sticky notes for feedback
Wave Simulation: Beach Formation
Use trays with water and sand/pebbles. Students create waves with spoons to mimic deposition, comparing gentle and strong actions. Record differences in a table.

What do you notice about the difference between a sandy beach and a pebble beach?
Facilitation Tip: During Image Hunt: Coastal Map, give each student a sticky note to mark one coastal landform they find, then have them explain their choice to a partner.

Teaching This Topic
Teach this topic through guided discovery rather than direct explanation. Start with hands-on sorting and modeling so students experience the processes themselves before naming the scientific terms. Avoid long explanations at the start; instead, let questions arise naturally from their observations. Research shows that children learn best when they connect physical actions to new vocabulary during open-ended exploration.
What to Expect
By the end of these activities, students will confidently sort beach materials by texture, explain how winds build dunes, and identify coastal features on maps. They will use accurate vocabulary like ‘prevailing wind,’ ‘deposition,’ and ‘erosion’ during discussions and reflections.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Sorting Station: Beach Materials, watch for students assuming all beaches feel the same.
What to Teach Instead
Ask students to close their eyes while sorting the materials by touch, then compare their piles by texture and size. Have them link each pile to a type of wave energy they observed in the tray.
Common MisconceptionDuring Fan Model: Dune Building, watch for students attributing dune formation only to waves.
What to Teach Instead
Pause the activity after the first dune forms and ask, ‘What moved the sand from the tray to the pile?’ Guide them to notice the fan and connect wind to deposition in dunes.
Common MisconceptionDuring Wave Simulation: Beach Formation, watch for students thinking dunes change size only because of waves.
What to Teach Instead
After building a small dune with the fan, have students gently blow on it or remove marram grass strips to show how erosion happens without waves. They observe and record changes immediately.
Assessment Ideas
After Sorting Station: Beach Materials, give each student a set of four pictures showing different coastal landforms. Ask them to circle the sandy beach and pebble beach, then write one word under each to describe the texture.
During Image Hunt: Coastal Map, ask students to pair up and explain to each other how they identified a sandy beach versus a pebble beach using the clues on the map.
After Fan Model: Dune Building, ask students to draw a simple dune on their card and label one thing that helps it stay in place, such as ‘marram grass’ or ‘wind direction’.
Extensions & Scaffolding
- Challenge: Provide a tray of mixed sand, silt, and pebbles and ask students to simulate a stormy coast by swirling water to create a new beach type; they present their findings to the class.
- Scaffolding: For students struggling with wind direction, give them a compass rose and ask them to place the fan pointing to the ‘prevailing wind’ before building dunes.
- Deeper exploration: Use a clear plastic shoebox to layer sediments and add water to show how gentle and powerful waves create different beach profiles over time.
Key Vocabulary
| Beach | A landform along the coast of an ocean, sea, lake, or river, made up of loose particles such as sand, pebbles, or shells. |
| Sandy beach | A beach made up of small, fine grains of sand, typically formed by calmer waves depositing these particles. |
| Pebble beach | A beach composed of small, rounded stones or pebbles, often formed by stronger waves that sort out finer materials. |
| Sand dune | A mound of sand formed by the wind, often found near coastlines or in deserts, where sand accumulates. |
| Marram grass | A type of tough grass that grows on sand dunes, with long roots that help to anchor the sand and prevent erosion. |
