2.5G
Change & constancy
Describe how conditions can cause objects, organisms, and systems to change or stay the same.
2.6A
Classify matter
Classify matter by observable properties (texture, flexibility, relative temperature) and identify solids or liquids.
2.6B
Change of properties
Investigate how physical properties can change (cutting, folding, sanding, melting, freezing).
2.6C
Build from small units
Show that small units can be combined or reassembled to form new objects; choose materials based on properties.
2.7A
Pushes & collisions
Explain how objects push on each other and may change shape when they touch or collide.
2.7B
Strength of push/pull
Investigate how the strength of a push or pull changes an object’s motion.
2.8A
