The Ocean Supports a Great Diversity of Life and Ecosystems – Tides and the Seashore

The Ocean Supports a Great Diversity of Life and Ecosystems – Tides and the Seashore

The ocean supports a great diversity of life and ecosystems. By starting at the seashore, we can learn how the changing tides can create extreme environments for all of the animals and algae that live there. Before heading to the seashore, it is important to know the tides, so it is safe to explore. We have come up with some great lessons and quizzes to learn about the tides and the seashore at home. There’s some fun activities including baking some Tidal Retreat cookies, creating a play about Tides and Tales and experimenting with gravity and water.

LESSON PLANS, ACTIVITIES, WORKSHEETS:

The aim of the lesson plan is for the children to develop their geography skills and learn about how the moon and sun’s influence tides on the seashore. This is to be supported by cross curricular activities including baking, a fieldtrip to the seashore and drama activities learning about the animals adapting to the different conditions caused by tides.

ACTIVITY: Drama Time - Telling Tales of Tides and the Extremes of the Seashore

  • Observe, investigate and record the daily changes to seashore environment caused by the tides, highlighting how the diversity of animals that live there have to adapt to extreme conditions. Create a drama piece, highlighting the tales of the tides and the extreme conditions the animals have to live in due to the changing tides – every day.
