GRADE 9 SCIENCE
Suggested Pedagogical Processes
The learners may be provided with opportunities individually or in groups
and encouraged to—
PP1: observe, group or classify materials, such as mixtures, based on their
properties, viz. solubility, passage of light, etc., by performing various
activities. Based on the observations, a discussion may be facilitated to help
arrive at the appropriate conclusions. Students with visual impairment or low
vision may be motivated to observe solubility of the materials by touching the
materials. (Caution should be taken while using the materials.)
PP2: design and carry out activities. For example, Tug of war to
understand balanced and unbalanced forces. They may be encouraged to
experiment by applying forces (equal and unequal) on an object in same and
opposite directions, followed by peer group discussion to generalise.
PP3: study the daily life experiences, using interdisciplinary approach such
as the cause behind cooling of water in earthen pots. They may be
encouraged to measure and compare the temperatures of water both in earthen
pot and metal containers, thereby helping them to relate process of evaporation
with cooling effect. Students with visual impairment or low vision may be
encouraged to feel the difference in temperature by touching the surface of the
containers.
PP4: conduct survey to understand the process of spreading of diseases.
They may be encouraged to collect data from doctors and nurses about various
diseases. They can prepare a report on spread, causes, prevention, and cure of
diseases. They may share their findings with the community through role plays,
skits and also campaign for prevention.
PP5: present their observations/ ideas/ learning through flow charts/
concept maps/ graphs and ICT tools.

PP6: gather data for calculating different physical quantities, such as
distance, displacement, velocity, which can be shared and discussed in groups
or with peers. Rubrics can be used to assess the conversion of units and
reporting results.

PP7: collect and analyse wide variety of graphs from newspapers,
magazines or the internet. They may be encouraged to draw, analyse and
interpret the graphs
(for example, distance – time graph, speed - draw, analyse and interpret the
graphs time, or acceleration-time graphs of motion of a vehicle on a straight
road)
PP8: write chemical formulae of simple compounds, chemical equations,
etc., using play way methods such as a game of cards.

PP9: select and use appropriate devices for measuring physical quantities.
They may be encouraged to find the minimum and maximum value that can be
measured by an instrument and note down the readings correctly.

PP10: collect information from books, e-books, magazines, internet, etc., to
appreciate the efforts of scientists made over time, for example, various models
of atoms, discovery of microscope, etc., and showcase it in the form of a
project or role play.

PP11: observe various technological devices and innovative exhibits such as
waste management kits, water filtration system, using low-cost or no-cost eco-
friendly materials, develop them and showcase it in science exhibitions, clubs
and parent-teacher meets.

PP12: share and discuss their beliefs and views regarding myths, taboos,
superstitions, etc. by initiating an open-ended debate, leading to the alignment
of their beliefs to the scientifically proven facts. They may also be involved in
awareness campaigns in the community.
