West Haven Public Schools

Unit Planning Organizer

Subject:   Science                                               

Grade:  2

Unit:  Solids and Liquids               

Pacing:  September -November

Essential Question(s):

1.      When comparing and contrasting solids, liquids, and gases, how are their properties alike and different?

2.      How is it possible that water flows faster than sand?

Big Idea(s):

1.      Different substances have different properties.

  1. Liquids and solids flow at different rates of speed.


CT State Standards (includes West Haven’s “Priority” GLES’s in BOLD and “Supporting” Standard

Priority Standards or GLEs :


2.1.1- Compare and contrast the properties that distinguish solids, liquids and gases.


2.1.2-Classify objects and materials according to their state of matter.




2.1.3- Measure and compare the size of different solids.

2.1.5-Design a fair test to compare the flow rates of different liquids and granular solids.




2.1.4-Measure and compare the volume of a liquid poured into different containers.
