Raksha and Tilak had visited many places with their parents
during vacation. During their stay in grandparents house in Ankola,
they could visit sea shore, and collected sea shells. They saw
variety of fishes, crabs, aquatic plants, mountains nearby with
plants of different structures and shapes. They also saw thick
forests on their way to their uncle's place -Dandeli. In another trip
to Rajasthan, they came across very less plants and the structure of
these plants were different compared to plants in their native place
. They traveled on camel on hot sand and collected various cactus
plants. They felt very hot in this area. But during their visit to
northern part of India, they felt very cold, and found trees with
very thin leaves and also the animals here were different . They
wondered and discussed about the various living beings they came
across during their travel. They were more surprised when they saw
small creatures like spider and silver fish between books in their
cupboard. Raksha started thinking why so many varieties of living
beings are there on this earth? and started collecting information
of these living beings. These are called organisms. She found that
there are tiny organisms also and all these living creatures are
grouped by different scientists on the basis of their habitat (place
they are found), their shapes structure and functions. She started to
ask more questions about the organisms and discussed with her brother
Tilak and also with elders about diversity of living organisms on
this earth. Her teacher told her that she cannot understand all the
types of organisms, their classification , structure and functions at
a stretch and as she proceeds to higher classes she can study in
detail about them.
*Developmental questions - Ask the students to document living organisms
*Developmental questions - Ask the students to document living organisms
With a narrative like this, the teacher can develop a lesson using
the inquiry-based approach. Some of the questions that could guide
this inquiry are:
# There are many living things around us. Are they all alike? Do you find them only on land?
# Which are the places they grow? What are these living creatures called ?
# How are they different from non-living things?
# How do these living things interact with non-living things and each other?
# What is the behavior of each of these?
# How do they grow in size? How do they become more or less in number?
