Grade 2:
Insects Unit
Overview
View the
Video
Introduction. This unit is a Full Option Science System (FOSS) kit
created by the Lawrence Hall of Science at the University of California,
Berkeley. It is published by Delta Education. The insects kit provides
experiences that heighten students' awareness of the diversity of animal
forms. They come to know first-hand the life sequences of a number of
insects. In each activity, an insect is introduced, and students observe
structures and behaviors, discuss their findings, and ask questions.
Students observe life cycles of insects and compare the stages of
metamorphosis exhibited by each species. The insects provided to the teacher
include mealworms, milkweed bugs, butterfly larvae, and crickets.
Building Successful Foundations in Science - Elementary science
integrates and organizes student scientific knowledge through a foundation
made up of 'Bricks" of Big Ideas put together with the "Mortar" of Unifying
Concepts.

Enduring Understandings
- important ideas that students should carry with them years beyond the
instruction received this year.
Scientific Process
-
A
scientific vocabulary is needed to communicate about the scientific
procedure.
-
A
hypothesis is a testable prediction as to the outcome of a scientific
investigation.
-
A
well designed investigation involves the use of a written plan that
identifies the materials to be used, the procedure to follow, and the
variables. A plan needs to be followed to make sure all steps in an
investigation are completed.
Scientists use many tools when conducting an investigation.
-
Complete data makes it possible to explain the results of an investigation
and compare it with the prediction.
-
When data is analyzed, the results can be communicated in a variety of ways.
-
Many tools are available to help gather data.
-
A
written plan must be followed in the correct sequence to make sure it is
done the same way each time. (Replication of results.) An
investigation should be done more than once to make sure data is accurate.
-
Data is
only as reliable as the people conducting the experiment.
-
Errors
can be determined by comparing data with another student or by repeating the
investigation.
Living Things
-
All things can be
categorized as living or nonliving. All living things
have basic needs for survival.
-
All animals within a
species have many common characteristics. Each insect has its
own unique characteristics.
-
All organisms must
consume food to survive. This can be in the form of plants or other
insects or animals.
-
Living organisms
have physical characteristics and structure that are unique to their
populations, while individuals exhibit variations within that structure. The habitat of the
organism must meet the physical needs
-
Some organisms
undergo simple or complete metamorphosis within their life cycle.
Technology
-
Technology makes it
easier to find and communicate information.
-
Many different
careers involve science or technology.
-
Data can be visually
represented with labeled diagrams, charts, tables, or graphs. Data can be
graphically represented through bar graphs, line graphs, pictographs, or
pie charts. Graphs are pictures of numbers.
-
Visual or graphic
data can be analyzed to predict further change.
-
Models make it
possible to represent events or objects that cannot be duplicated.

Essential Questions
- most important “big picture” questions students should be able to answer
after completing learning activities.
Scientific Process
-
What common
vocabulary should be used when conducting an investigation?
-
Why are predictions
an important part of the scientific process? How can we make better
predictions?
-
Why should we follow
a plan when conducting an investigation? What tools are
available to gather data when conducting an investigation? How does data help
us explain our investigation? What are some of the ways we can collect
data? How can we
communicate the results of our investigation to others? How can we make sure an investigation is done the same way each time?
Living Things
-
What is necessary
for all organisms to survive?
What is the
difference between living and nonliving things?
-
What are some
specific characteristics of the organisms that allow them to adapt and
survive in their environments? What characteristics
are common to each of these species?
-
What characteristics
are specific to the butterflies, mealworms, crickets, and milkweed bugs?
-
What structures are
specific to insects and what differences exist among the insect
populations being studied?
-
What do insects eat?
-
What is the life
cycle of a meal worm, butterfly, cricket, and milkweed bug?
Technology
-
How can you utilize
technology to gain knowledge and, communicate information?
-
What careers use
science and technology?
-
How can data
accuracy be determined? How is data gained
and how are experiments replicated accurately?
-
How can errors in
data be discovered? How can data be
visually represented?
-
What is the best
type of graph for specific data? How does data help
make better predictions?
-
How can models help
complete a scientific investigation?
Safety
-
What are safe
laboratory techniques?
-
What tools are
needed to gather the data required, and how are they appropriately used?
