Lesson Plan of Respiration in Plants
General Science Grade VI
Students’ Learning Outcome
·
Explain the importance and
process of respiration in plants
Information for Teachers
·
Like all other organisms,
plants require oxygen for getting energy from food
·
They also require to release
extra carbon dioxide from their bodies
·
During day time plants
utilize the carbon dioxide (produced during respiration) in photosynthesis and
for respiration, they utilize the oxygen produce during photosynthesis
·
Plants don’t have specialized
breathing mechanism for gaseous exchange like animals
Concept Map
Material / Resources
Germinating seeds, flask, thermometer, stand
Worm up activity
·
Ask the following questions
to the class.
o What do you need to grow?
(Expected response: food and energy)
o From where do you get this energy?
(Expected response: by the breakdown of food)
o Do you know the name of the process involved in
getting energy from food?
(Expected response: respiration)
·
Now introduce the today’s
topic to the students.
Development
Activity 1
·
Ask the questions:
o How the chemical energy stored in food
molecules is made available for life process?
(Expected response: by chemical reaction)
o Inform the students that these chemical
reactions are collectively called respiration.
o Link the above discussion by explaining the
process of respiration in terms of a simple equation.
o Draw this equation on the board:
Carbon
dioxide
+
Water
+

Activity 2
·
Set the apparatus as shown in
diagram and draw this diagram on the board to explain that this experiment is
used to investigate the release of energy (heat) during respiration
·
Now conclude this activity by
asking the following questions
o Why germinating seeds are used in this
experiment?
(Expected response: in germinating seeds the
process of respiration is going on)
o What will be the change in the reading of the
thermometer after the experiment?
(Expected response: an increase in the reading
of the thermometer)
o How does the measurement of thermometer
indicate that the weeds have released energy?
(Expected response: in germinating seeds the
process of respiration is going on. During the process of respiration the
energy is released)
·
Ask about the importance of
respiration and enlist the points on the board and ask the students to copy on
their notebooks.
Sum up / Conclusion
·
Ask the students, what we
have learnt? Expected response will be: in the process of respiration plants
take in oxygen and release carbon dioxide (CO2), and this process continues day
and night.
·
During day time both process
of photosynthesis and respiration are going on thus CO2 during respiration is
used in photosynthesis and oxygen released during photosynthesis is used for
respiration.
Assessment
·
Draw the given table on the
board
·
Ask the students to fill and
copy on their notebooks

Follow up
·
Write the following questions
on the board and ask them to copy and solve as home work on their notebook
o In contrast to photosynthesis, why respiration
in plants continues during day and night
o What is the purpose of respiration?
o What is the energy released in respiration used
for?
