2nd Grade: Solids and Liquids
Content Standard II: Physical
Essential Learnings:
What do students need to know and be able to do?
Big Ideas:
1. Experimental Design (observations, question, hypothesis and
design)
2. Scientific testing (conduct investigations, collect and organize
data)
3. Analysis and Conclusions (analysis trends, and conclusions)
Students will…..
Observe and describe the physical properties of solids and liquids by
utilizing screens and magnifying glasses.
Sort materials according to physical properties.
4. Structures and properties of matter
Use information gathered to conduct an investigation on an unknown
material.
Essential Vocabulary:
sort
viscous
property
transparent
observe
liquid
flow
solid
separate
translucent

Reteaching Strategies
Suggested Time Frame:
Scope and Sequence:
18 – 45 minute investigations (not including the optional activities).
Student background knowledge would be from doing experiments in
kindergarten on wood and paper in water.
