An introductory lesson to OCR B Rivers and Coasts unit

1. Rivers and coasts
Starter activity:

2. Rivers and coasts
• Learning objectives:
– All to know key terms of the advanced hydrological
cycle
– Most to be able to separate terms into stores and
flows, inputs and outputs
– Some to start to link the hydrological cycle to how it
might affect people and their lives
• Key terms/literacy focus today: Hydrological key
terms
• Your starter questions?

3. The Hydrological cycle
Why should we bother
learning about this?
Let’s see at the end of
the lesson.

4. Key term Definition Key term Definition
Evaporation Water slowly seeping Precipitation Water moves towards
into the bedrock the sea through rivers
and streams
Groundwater flow The movement of water Channel flow Water soaks into the soil
over the surface of the layer
ground
Percolation Water falling from the Infiltration The very slow
sky as rain, hail, sleet movement of water
and snow through the bedrock
Evapotranspiration Precipitation is Overland flow Water evaporates from
prevented from reaching the leaves of plants back
the ground by leaves into the atmosphere
Throughflow Water changes state Interception Water moving through
from a liquid to a gas the soil layer
Condensation Water changes state With a partner, match up the
from a gas to a liquid
definition to the key term on your

5. The hydrological cycle
In pairs, allocate the correct key terms and definitions to each
letter on your printed copy of the diagram to fully describe
and explain the hydrological cycle

6. The Hydrological Cycle
• Extension – colour code and label extra areas
on your diagram labels to show the following:
– Inputs to the hydrological cycle/system
– Outputs from the hydrological cycle/system
– Stores where water resides for significant
amounts of time
– Flows where water moves between stores

7. How could this affect humans?
• Linking back to slide 3, let’s start to think
about how this could affect people (and
therefore why we bother studying it).
• Examine your diagram. Identify areas where
you think people’s lives could be affected &
add an annotation to explain how this could
work. Example?
