2nd grade Performance Expectations 2-PS1 (Matter and its Interactions)
2-PS1-3
. Make observations to construct an evidence-based account of how an object made of a small set of pieces can be
disassembled and made into a new object.
SEP:
Constructing explanations and designing solutions in K–2 builds on prior experiences and progresses to the use of evidence and ideas in constructing evidence-based accounts of natural phenomena and designing solutions.
Make observations (firsthand or from media) to construct an evidence-based account for natural phenomena.
DCI 1A:
Different properties are suited to different purposes.
A great variety of objects can be built up from a small set of pieces
Activity: Legos
CCC Energy and Matter:
Objects may break into smaller pieces and be put together into larger pieces, or change shapes.
Activity: Legos
2-PS1-4.
Construct an argument with evidence that some changes caused by heating or cooling can be reversed and some
cannot.
SEP:
Engaging in argument from evidence in K–2 builds on prior experiences and progresses to comparing ideas and representations about the natural and designed world(s).
Construct an argument with evidence to support a claim.
CCC Cause and Effect:
Events have causes that generate observable patterns.
DCI 1B:
Heating or cooling a substance may cause changes that can be observed. Sometimes these changes are reversible, and sometimes they are not.
RI.2.8
: Describe how reasons support specific points the author makes in a text. (2-PS1-2),(2-PS1-4)
W.2.8:
Recall information from experiences or gather information from provided sources to answer a question.
2-PS1-2.
Analyze data obtained from testing different materials to determine which materials have the properties that are best suited for an intended purpose.
SEP
:Analyzing data in K–2 builds on prior experiences and progresses to collecting, recording, and sharing observations.
Analyze data from tests of an object or tool to determine if it works as intended.
DCI 1A:
Different properties are suited to different purposes.
CCC Cause and Effect:
Simple tests can be designed to gather evidence to support or refute student ideas about causes.
Influence of Engineering, Technology, and Science, on Society and the Natural World:
Every human-made product is designed by applying some knowledge of the natural world and is built using materials derived from the natural world.
