and representations
View year level mapping of
concepts
Review reasons why water quality is important and should be tested.
Construct and test a water filter.
View a demonstration of water filtration.
Discuss the effectiveness of filtration as a water treatment process.
Identify contaminants that could remain in water supplies such as
reservoirs following filtration.
Observe and discuss the filtration system at NKIEEC
Observe and discuss the role mangroves play in filtering water in
catchments
•
Explore the movement of water through a water filtration at NKIEEC.
Define vocabulary associated with water treatment such as
flocculation, filtration, aeration, sedimentation, chlorination,
coagulation and disinfection.
Compare treatment processes to separation techniques.
Explore and observe how mangroves filter the water in catchments
Explore and discuss the soakage trenches on the cabins
Explore the reef and the way sediment has been filtered
Discuss scientific and technological practices
•
Describe scientific practices that have been implemented to improve
water quality and water treatment.

Lesson objectives
Sheet — Construct a water filter
Students will:
Video — Waterways filter — Part A
understand the process by
which water is treated for
human use and consumption.
Video — Waterways filter — Part B
Evidence of learning
Sheet — Reservoir contaminants
Can the student:
describe the stages of the water
treatment process?

techniques?
Ideas for monitoring
Monitor students’ ability to:
understand the technical
processes involved in treating
water for human consumption.
Learning alerts
Be aware of:
students’ thinking that water
comes straight from reservoirs
or dams.
Suggested next steps for
learning
Ensure students understand
that water moves through water
treatment plants to meet high
standards of quality before
being available for human
consumption.

Safety
Teachers need to:
•
•
Ideas for differentiation
Support
Provide animated
representations to demonstrate
movement of water through a
treatment plant
Extension
Have students examine and
describe treatment processes of
local water treatment plants.
