Coastal Erosion: Waves, Tides & Currents
Investigating how the sea shapes the Irish coastline through the processes of wave action, tidal movements, and ocean currents.
Key Questions
- Analyze how waves create both cliffs and beaches along a coastline.
- Differentiate between the erosional impacts of destructive and constructive waves.
- Explain the role of tides and currents in coastal sediment transport.

About This Topic
Impressionist techniques focus on the fleeting nature of light and the beauty of the visible brushstroke. For 5th Class, this means moving away from smooth 'coloring in' and toward 'broken color', placing small dabs of different colors side-by-side to let the eye blend them. This topic fulfills NCCA standards for exploring the work of artists and experimenting with the physical properties of paint.
This unit connects to History by looking at the 19th-century shift in how people viewed the world, and to Science through the study of light and optics. Students learn that an image doesn't need fine detail to be 'readable.' This concept is best understood through active observation of how light changes throughout the day. This topic comes alive when students can physically model the patterns of light they see on a simple object and attempt to capture it quickly before the sun moves.
Active Learning Ideas
Inquiry Circle: The 10-Minute Light Study
Place a white object (like a jug) in a window. Groups sketch it at 10:00 AM, 12:00 PM, and 2:00 PM using only colored pastels to show how the shadows change from blue to grey to yellow as the day progresses.
Peer Teaching: The 'Dab' Technique
In pairs, one student practices making short, thick 'impasto' strokes while the other practices 'optical mixing' (dots of yellow and blue to make green). They then teach their partner the best way to hold the brush for each effect.
Gallery Walk: Squint Test
Display student works. The class walks around, squinting their eyes at the paintings. They discuss which paintings 'come together' best when blurred, helping them understand that Impressionism is about the overall impression, not the detail.
Watch Out for These Misconceptions
Common MisconceptionShadows are always black or grey.
What to Teach Instead
Students often reach for the black paint for shadows. Showing them Impressionist works where shadows are deep purple, blue, or green helps them see that shadows are actually full of reflected color.
Common MisconceptionYou have to mix the paint perfectly on the palette first.
What to Teach Instead
Students often over-mix until the color is 'mud.' Encouraging them to mix 'on the page' by placing two colors side-by-side surfaces the concept of optical mixing more effectively than a lecture.
