This document outlines a lesson plan for 2nd grade science focused on the states of matter: solids, liquids, and gases. It includes curriculum objectives, interactive activities for students to classify and observe matter, and key concepts related to the properties of different states. Additionally, it provides resources and references for further education on the topic.

3. Curriculum Objectives 1.1
• COMPETENCY GOAL 3: The learner will
observe and conduct investigations to build an
understanding of changes in properties.
▫ 3.01: Identify three states of matter.
 Solid
 Liquid
 Gas
North Carolina Standard
Course of Study
North Carolina Standards:
Second Grade Science

4. Curriculum Objectives 1.2
• COMPETENCY GOAL 3: The learner will observe and
conduct investigations to build an understanding of
changes in properties.
▫ 3.02: Observe changes in state due to heating and
cooling of common materials.
▫ 3.04: Show that solids, liquids and gases can be
characterized by their properties.
▫ 3.05 Investigate and observe how mixtures can be
made by combining solids, liquids or gases and how
they can be separated again.

5. Lesson Plan Objectives 1.1
• Students will be able to:
▫ Classify materials as solids, liquids, and gases.
▫ Define the terms solids, liquids and matter.
▫ Show that when materials are manipulated they
can take on different properties.

6. Lesson Plan: Introduction: Matter
• Ask students to write down things they think are
solids, liquids and gases.
• Ask them to define each of these three things.
• Discuss in groups, or at their table, what they
have written on their lists.
• The teacher will ask individuals for an example
from their list and the teacher will confirm or
deny their categorization.

7. Lesson Plan: Involvement: Matter
• Each table/group will approach a table to find
things that are solid and liquid items.
• They will observe the items through touch, look
and smell.
• On a chart, they will write down what each item
was and what matter it consisted of.
• They will return to their teams and then be
asked again, to name solids and liquids.

8. Lesson Plan: Observation: Matter
• The students have now discovered the difference between liquids and
solids. Now, they need to experience with gases.
• There will be two items sitting on a particular table, a candle and a balloon.
(Note: Hands-on is eliminated from this portion due to fire use).
• The candle will be lit by the teacher and she will ask what they expect will
happen to it.
• A balloon will be blown up with human air and she will ask the students
what went into it.
• The students should observe the materials and what is happening to the
materials.
• Students will record observation to their ability and return to seats

9. What did they learn?
• Solids:
▫ Tends to keep its form rather than moving freely,
molecules are compound, firm and compact.
 Examples: ice cubs, blocks, wood, soap bars, flowers
• Gases:
▫ Fluid form of a substance which can expand and fill a
space. It is not a liquid or solid, but more of a vapor.
 Examples: air, carbon dioxide, heat, steam
• Liquids:
▫ Readily flowing, fluid, molecules move freely
throughout a substance.
 Examples: water, other sources of drinks

10. Important Information
• Molecules are what hold objects together.
• Hydrogen and oxygen are examples of gaseous
matter.
• A conversion from solid to liquid is known as
melting.
• When something evaporates it turns into a gas.
• Only liquids and gases can truly take the shape
of a container it is put into.
