Grade 2:
Overview of the Year
Overview
Topics in second
grade science focus on learning critical science skills and include units on
Insects, Air and Weather, Balance and Motion, and Changes. Each unit
includes hands-on, minds-on, research-based kits that give students
opportunities to "do science" while learning science vocabulary, concepts
and skills. Each unit equips students to improve their reading and writing
skills with reading resources designed for a range of reading abilities.
Science Kits are shared across the district, so students will follow the
curriculum scheduled for their particular school. Although the order may
differ, all students will receive instruction on the topics listed on the
menu to the right.
Students that have experienced a deeper, integrated experiences with science
concepts and processes demonstrate higher levels of success in secondary
science.
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.
-
Constancy and Change: Although most things are in the process
of changing, some properties remain constant (i.e. the speed of light).
(Earth/Space
Science)
-
Weather conditions
change over time. Changes can be organized, compared, and
predicted.
(Earth/Space
Science)
-
Interdependence: Living things interact with one another and their
environment for existence and balance. (Life Science)
-
Insects have
physical characteristics and structure, undergo changes within life
cycles, and interact with each other and their environments.
(Life Science)
-
Order and Organization of Systems: A system consists of components/parts
that interact. (Physical Science)
-
The stability of a
system is dependent upon the position of its components. (Physical
Science)
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?
Movement
-
How do objects move? How are objects able to roll? How do changes in energy input affect the outcome?
-
How do objects and counterweights interact in a simple system to achieve
balance?
-
What happens to the object when it experiences an outside force?
Living Things
-
What is the difference between living and nonliving things? What characteristics are specific to the butterflies, mealworms,
crickets, and milkweed bugs? What do insects eat?
-
What is necessary for all organisms to survive?
-
What structures are specific to insects and what differences exist among
the insect populations being studied?
-
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 is the life cycle of a meal worm, butterfly, cricket, and milkweed
bug?
Weather
-
How does weather affect states of matter: solid, liquid, or gaseous?
-
How does the sun affect weather daily? What are some terms that help us describe the weather?
-
How are daily activities affected by the weather? How do we measure changes in weather?
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 does data help make better predictions?
-
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 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?
Standards
Highest
Frequency Standards
High
Frequency Standards
Other
Standards & E-skills
Standard 1:
Students understand the processes of scientific investigations and design,
conduct, communicate about, and evaluate such investigation.
Standard
2:
Physical Science: Students know and understand common properties, forms, and
changes in matter and energy. Students know that matter has characteristic
properties which are related to its composition and structure. Students
understand that energy appears in different forms and can move (be
transferred) and change (be transformed). Students understand that
interactions can produce changes in a system, although the total quantities
of matter and energy remain unchanged.
Standard
3:
Life Science: Students know and understand the characteristics and
structures of living things, the processes of life and how living things
interact with each other and their environment. Students know and understand
the characteristics of living things, the diversity of life, and how living
things interact with each other and with their environment. Students know
and understand interrelationships of matter and energy in living systems.
Students know and understand how the human body functions, factors that
influence its structures and functions compared with those of other
organisms. Students know and understand how organisms change over time in
terms of biological evolution and genetics.
Standard
4:
Earth and Space Science: Students know and understand the processes and
interactions of Earth's systems and the structure and dynamics of Earth and
other objects in space. Students know and understand the composition of the
Earth, its history, and the natural processes that shape it. Students know
and understand the general characteristics of the atmosphere and fundamental
processes of weather. Students know major sources of water, its uses,
importance, and cyclic patterns of movement through the environment.
Students know the structure of the solar system, composition and
interactions of objects in the universe and how space is explored.
Standard
5:
Students know and understand interrelationships among science, technology,
and human activity and how they affect the world.
Standard
6:
Students understand that science involves a particular way of knowing and
they understand common connections among scientific disciplines.

Research confirms that students need at least 6
opportunities through varied activities to experience new vocabulary in
order to acquire a conceptual understanding. The following activities
are endorsed by the Mid-Continental Research in Education Laboratory (McREL)
Six Step Strategy for Improving Vocabulary. Instead of looking at a
dictionary first, follow the 6 steps to insure students have a full
understanding. Read more about
Research on Teaching
Vocabulary.
-
Step 1:
Teacher provides a description, explanation, or example of the term
-
Step 2:
Student restates the description, explanation, or example in his/her own
words
-
Step 3:
Student designs a visual representation
Use the suggested
Vocabulary
Activities for Steps 4-6.
-
Step 4:

writing
-
Step 5:
Students review and discuss word meanings
-
Step 6:
