Gas

Matter is everything around us. Gas is something that can't be seen. It looks like air or steam. It is something we can put our hands through. 

Examples:

1. Steam

2. Oxygen

Question: What is something we can do to see gas more clearly? 

Solid

Matter is anything that takes up space. Solid is anything that holds it's own shape. It doesn't change unless it's damaged or altered. 

Examples of solid:

1. Rock

2. Eraser

3. Table

Question: Is it possible to change solids into liquid or gas?

Liquid

Matter is anything that takes up space. Liquid is a state of matter that takes up shape of its container. 

Examples of liquid are:

1. Juice

2. Water

3. Milk

Question: Can all liquid turn into solids? 

Instruction for students

Dear 4th grade scientists,


Today we will learn about the three different states of matter. Each group will be given a different state of matter to research about. Here are the following groups:


Herbivore: Solid


Carnivore: Gas


Omnivore: Liquid

Each of the following groups must do these following task:


1. Write 2-3 sentences about what matter is and their groups state of matter.


2. Give at least 2-3 examples of the state of matter.


3. Provide at least ONE picture of their state of matter.


4. What would you want to learn more about your topic?


These are the following websites that can help you with your research about the three states of matter:


1. Chem4Kids- States of Matter


2. ABYCA- States of Matter


3. Easy Science for Kids- States of Matter



NYS Science Standards:

Matter exists in three states: solid, liquid, gas. (3.2a) 

• Solids have a definite shape and volume. 
• Liquids do not have a definite shape but have a definite volume. 
• Gases do not hold their shape or volume.

Matter takes up space and has mass. Two objects cannot occupy the same place at the same time. (3.1a)

Temperature can affect the state of matter of a substance. (3.2b)

Objects and/or materials can be sorted or classified according to their properties. (3.1f)

NGSS Cross-Cutting Concepts:

Energy and Matter: Flows, Cycles, and Conservation: Tracking energy and matter flows into, out of, and within systems helps one understand their system’s behavior. 

• Matter is made of particles. 
• Matter flows and cycles can be tracked in terms of the weight of the substances before and after a process occurs. The total weight of the substances does not change. This is what is meant by conservation of matter. Matter is transported into, out of, and within systems.
