Second Grade Curriculum
|
The
performance expectations in second grade help students formulate answers to
questions such as: “How does land change and what are some things that cause it
to change? What are the different kinds of land and bodies of water? How are
materials similar and different from one another, and how do the properties of
the materials relate to their use? What do plants need to grow? How many types
of living things live in a place?” Second grade performance expectations
include PS1, LS2, LS4, ESS1, ESS2, and
ETS1 Disciplinary Core Ideas from the NRC Framework. Students are expected
to develop an understanding of what plants need to grow and how plants depend
on animals for seed dispersal and pollination. Students are also expected to
compare the diversity of life in different habitats. An understanding of
observable properties of materials is developed by students at this level
through analysis and classification of different materials. Students are able
to apply their understanding of the idea that wind and water can change the
shape of the land to compare design solutions to slow or prevent such change.
Students are able to use information and models to identify and represent the
shapes and kinds of land and bodies of water in an area and where water is
found on Earth. The crosscutting concepts of patterns; cause and effect; energy
and matter; structure and function; stability and change; and influence of
engineering, technology, and science on society and the natural world are
called out as organizing concepts for these disciplinary core ideas. In the
second grade performance expectations, students are expected to demonstrate
grade-appropriate proficiency in developing and using models, planning and
carrying out investigations, analyzing and interpreting data, constructing
explanations and designing solutions, engaging in argument from evidence, and
obtaining, evaluating, and communicating information. Students are expected to
use these practices to demonstrate understanding of the core ideas.
