Science!&!Engineering!Practices!
SEP 6a: Constructing Scientific Explanations: Constructing explanations in 6–8 builds on K– 5 experiences and progresses to include
constructing explanations supported by multiple sources of evidence consistent with scientific ideas, principles, and theories.
!
By the end of the grade band students will have had a structured opportunity to develop an understanding of each of these. Individual
lessons or units should include opportunities for stud ents to practice one or more of the following components ……
!
1) Articulate a
claim/explanation (a testable
statement or conclusion that
answers a question about how
or why) that is based on and
consistent with available
evidence
!
Clearly!articulate!a!claim!about!(an!explanation!of)!a!phenomenon!that:!
a. is!a!testable!statement!or!conclusion!that!correctly!answers!a!question!about!how!or!why!!
b. relates!the!given!phenomenon!to!a!relevant!scientific!idea!!
c. includes!a!grade-appropriate!level!of!the!mechanism!involved!!
d. is!consistent!with!available!evidence!!
e. includes!qualitative!or!quantitative!relationships!between!variables!that!predict!and/or!describe!phenomena!!
2) Identify and describe
appropriate and sufficient
evidence that support the
claim/explanation
!

3) Describe the reasoning
(mechanism of how or why)
that connects the evidence to
the claim/explanation using
scientific ideas/principles
!
