GROWING AND CHANGING
Lesson 6
Teacher notes
Science inquiry focus:
How do offspring of insects grow and change?
Science Inquiry Skills:
• Questioning and predicting QP
• Planning and conducting PC
• Processing and analysing data and information PA
• Evaluating E
• Communicating C
Science as a Human Endeavour:
• Students act like scientists when they make observations
and describe the growth of insects.
• Students explore how science is used to identify the stages
that animals have in common as they grow and change.
Technology/Engineering/Mathematics links:
• using a digital device to take a photograph
• identifying a predictable pattern in the stages of insects, and
using it to sort insect images correctly
Background information
• Most insects completely change their size, shape and
colour during a life cycle of four stages from egg, larva,
pupa to adult. This is called complete metamorphosis.
These insects include butterflies, moths, flies, ants, bees,
beetles and ladybugs.
• Some insects, such as grasshoppers and cockroaches,
have three stages—egg, nymph (larva) and adult. The
larva looks similar to the adult, so it is called incomplete
metamorphosis.
• Other insects, like silverfish and lice, have no
metamorphosis. They hatch from eggs looking like
miniature adults and grow larger over time.
• This lesson is to highlight that some living things do not
look the same as an offspring as they do as an adult. They
do, however, have predictable stages of development
and observable changes. It is not meant to go too in
depth into life cycles as this is covered in Year 4.
Assessment focus:
• Use page 26 as a formative
assessment of the student’s
understanding that insects go
through common changes and
do not look the same at birth
through top adulthood.
• Page 26 can also be used as a
summative assessment when
they compare the changes of
all animals and how they are
different or the same.
