2. Instruct students to prepare a plan of the practical report.
3. Review the teaching courseware and/other related teaching aids with animation or video clips.
4. Prepare power point presentation to be used in classroom teaching.
5. Prepare activity sheet for the lesson.
3. LESSON x: 3.6 Understanding Bernoulli’s principle
Pedagogy: Observation and classroom discussion with LCD presentation
Time: 2 periods

Learning
Activities
Content T&L Strategies / Methods
Introduction
(30 – 40 minutes)
Carry out activities
to gain an idea that
fluid velocity affects
fluid pressure.
Writing
observations on
work sheet.
Refer to text book page 100.
(i) When a fluid moves, there is a change in its
fluid pressure.
(ii) The higher the fluid velocity, the lower the
fluid pressure.
(Work sheet is given out to students.)
• Carry out Activity 3.6A, 3.6B, 3.6C text book page
101. Teachers are advised to split the students in
groups to do the 3 activities. The 3 activities are
placed in 3 separate stations to encourage as many
students as possible to participate actively in them.
The groups rotate among stations.
• Students fill in answers in their worksheet as they do
the activities.
Scientific Skills : Observing, inferring, predicting
Development 1
(10 – 15 minutes)
Referring to text
book, discussion.
Bernoulli’s principle states that the pressure of a
moving fluid decreases as the speed of the fluid
increases.
• Teacher states Bernoulli’s principle. (Text book page
100)
• Teacher demonstrates Bernoulli’s principle using a
Venturi tube. (Text book page 102)
4. Development 2
(30 – 35 minutes)
Practical session.
Write down the
observations.
• Students carry out experiment 3.5 (practical book
page 55).
• Students write down their observations.
Scientific Skills : Observing, inferring and predicting.
Development 3
(10 – 15 minutes)
Refer to text book,
discuss applications
of Bernoulli’s
principle.
Answer questions in
work sheet.
The airplane wing (an aerofoil) is shaped in such
a way that the air flowing past it creates a lifting
force on it. The lift is strong enough to balance
out the gravitational pull on the airplane.
• Students are requested to refer to text book page
103, Physics in Action to discuss applications.
• View computer simulations to observe air flow over
an aerofoil to gain an idea on lifting force
• Guide students to go through the questions in the
work sheet.
Scientific Skills : Connecting and predicting.
Moral and Scientific Value:
• Having critical and analytical thinking.
• Being flexible and open-minded.
Closure
(5 to 10 minutes)
Summarising the
lesson.
Problem solving
(homework)
(i) Summary from work sheet.
(Go over the answers work sheet.)
• Guide students to summarise the lesson by referring
to their work sheet.
• Give homework to students – 3.6 Questions (text
book page 104)
Moral and Scientific Value:
• Having an interest and curiosity towards the
environment.
• Cooperation
