Properties of Matter Benchmarks SC.2.P.8.2 Identify objects and materials as solid, liquid or gas. SC.2.P.8.3. Recognize that solids have a definite shapes and that liquids and gases take the shape of the container. SC.2.N.1.1 Raise questions about the natural world, investigate them in teams through free exploration and systematic observations, and generate appropriate explanations based on those explorations. SC.2.N.1.3 Ask ”how do you know?” in appropriate situations and attempt reasonable answers when asked the same question by others. SC.2.N.1.5 Distinguish between empirical observation (what you see, hear, feel, smell, or taste) and ideas or inferences (what you think). LAFS.2.RI.2.4Determine the meaning of words and phrases in a text relevant to a grade 2 topic or subject area LAFS.2.SL.1.1 Participate in collaborative conversations about topics and texts with peers and adults in small and larger groups.

What is matter? Matter is everything around us. Including you and me. Matter is the material or “stuff” everything is made of. Matter is anything that mass and takes up space. Look around the room and identify some matter. How can we tell the matter apart? By its properties. What are some properties of matter? Color, texture, shape, size, odor … What are the three states of matter? solid, liquid, and gas Engage: Ask the essential question: What is matter? and click on the hyperlink matter. If students need extra help with content review, click on hyperlinks for content videos: properties, mass and takes up space.

What is Matter? By Pam Dillier Song to tune of Three Blind Mice What is matter? A solid, liquid, or a gas It takes up space and weighs something, too. It’s everywhere - that includes you and me. Did you ever think such a thing could be true? That is matter. Engage: Sing song together. What is Matter?

Explain: Print out reading passage from Discovery Explain: Print out reading passage from Discovery. Have students read silently first and record answers in their notebooks. Then read together and check answers.

What’s a Solid? A solid’s a solid. It doesn’t change shape. It can’t move around; It stays in one place. Your desk is a solid And so is your chair. Just look in the classroom— Wow? They’re everywhere. Explain: Ask What’s a Solid? Click on Discovery Ed. Hyperlink Video Solid. Discuss what was learned from the video. Then read and discuss poem. Department of Science

What properties do all solids have in common? model A solid has its own definite shape and definite volume. A solid keeps its shape even when it moves. The particles in solids are fit together very tightly and vibrate in place. Click on link below: Properties of Matter: Particle Simulator Explore and Explain: Use some kind of rectangular prism or cube. (block, starburst candy, textbook,, cube). Have a volunteer measure its volume. L x w x h = volume. Pass it around. Is it keeping its shape? Students take notes in their journal.

Division of Academics - Department of Science What’s a Liquid? A liquid moves smoothly. We say that it flows From one place to another— How quickly it goes. We know that most liquids Are easy to see. With no shape of their own. They not like you and me. Explain: Ask What’s a Liquid? Click on Discovery Ed. Hyperlink Video Liquid. Discuss what was learned from the video. Then read and discuss poem. Division of Academics - Department of Science

What properties do all liquids have in common? Model Liquids have a definite volume. Liquids take the shape of their container. Liquids can be poured. The particles in liquids are not as close together as the particles in solids and move more freely than particles of solids. Click on link below: Properties of Matter: Particle Simulator Explore: Show two 100 mL of colored water. Pour 100 mL of colored water into a baggy. What happens to the liquid water? Compare. Then have a volunteer turn over the baggy over a blue tray. What happens to the shape of the liquid now? Why?

What’s a Gas? Air is a gas. We can’t see it, that’s true: But often we feel it In things that we do. It keeps up a kite. Air fills up a bubble. Without it to breathe We would be in BIG trouble. Explain: Ask What’s a Gas? Click on Discovery Ed. Hyperlink Video Gas. Discuss what was learned from the video. Then read and discuss poem. Department of Science

What properties do all gases have in common? model Gases have no definite size or shape. A gas takes the shape of its container. A gas will fill all the space inside a container. The particles in gases move freely in all directions. Explore: Get an empty baggy and a straw. Have a volunteer inflate it and close the baggy. Then have a volunteer open it. What happens to the air?

Bag It! What’s My State of Matter? Does it take up space? Does it have weight? Is it visible? Can it change shape easily? Can another solid pass through It easily? Solid Liquid Gas TE: SC.2.P.8.3. Bagging Matter Lab activity Materials needed: 3 resealable quart size bags; straw; colorful block; water tinted with food coloring Engage and Explore: Investigate the three states of matter with a whole group demonstration. Display the chart on the slide with the questions listed. Follow procedures from Bagging Matter Lab activity . Conclusion: Bag #1 is a _______________ because … Bag #2 is a _______________ because … Bag #3 is a _______________ because …

States of Matter Review Properties: Model: Examples: 1. Gas Liquid Solid Takes the shape and volume of its container. Has a definite volume, but takes the shape of its container. Has a definite shape and volume. 2. Explain: Students make a three part foldable: States of Matter 3.

Division of Academics - Department of Science Three States of Matter Explore the bag of items. Observe their properties. Then classify them into their state of matter. Show your thinking on a three part Venn Diagram. Ahead of time prepare a box or a bag filled with a small balloon full of air, a small drum (see Can Drum for a homemade version), a sealed plastic bottle of water, a block of wood, and any other random objects that contain solids, liquids, and gases for every group of students. Explore: First click on the Discovery Ed. hyperlink Three States of Matter and have volunteers complete the exploration. Place a box or a bag filled with a small balloon full of air, a small drum (see Can Drum for a homemade version), a sealed plastic bottle of water, a block of wood, and any other random objects that contain solids, liquids, and gases for every group of students. Have the students explore and then classify the items. Students can how their work on three part Venn Diagram. Division of Academics - Department of Science

Quiz Which state of matter am I? 1. 2. 4. 3. 5. 6. 7. Evaluations: Answers – 1. solid and gas 2. liquid 3. solid 4. model of gas particles 5. model of liquid particles 6. gas and solid 7, model of solid particles Extend: Here are some fun home activities to help your students learn more about solids, liquids, and gases: To show an example of water changing from a liquid to a gas, take a tea kettle and boil some water. Have your child observe the steam coming from the kettle. Be sure your child stays a safe distance from the hot steam. To show water changing from a liquid to a solid, make popsicles with your child. Fill an ice cube tray with juice.  Insert a clean stick in each compartment and freeze.  Division of Academics - Department of Science

Reflection How can matter change form? What is a solid? Give two examples. Answer: A solid is a state of matter with a definite size and shape. Examples will vary. 2. What is a liquid? Answer: A liquid is a state of matter with a definite size but no definite shape. Examples will vary.  3. What is a gas? Answer: A gas is a state of matter with no definite shape, size, or color. Examples will vary.   How can matter change form? Answer: Matter can change form in different ways based on temperature and the Sun. Some examples are when ice melts or water evaporates.
