MATTER: PROPERTIES AND CHANGES 5.P.2.2 Compare the weight of an object to the sum of the weight of its parts before and after an interaction. 5.P.2.3 Summarize properties of original materials, and the new material(s) formed, to demonstrate that a change has occurred. CLEAR LEARNING GOAL AS A STUDENT I WILL BE ABLE TO IDENTIFY AND DEFINE MATTER. MATTER IS EVERYWHERE AND EVERYTHING! MATTER IS ANTHING THAT TAKES UP SPACE! MATTER IS MADE UP OF TINY PARTICLES CALLED ATOMS! •Anything that has a mass and a volume Matter can be found in three different types. These three types are considered the three STATES of MATTER. 1. Solids 2. Liquids 3. Gasses A SOLID is matter that has a defined shape and will not lose its shape. FIXED VOLUME AND FIXED SHAPE Examples of solids: 1. Chair 2. Table 3. Golf Ball 4. Hockey Puck 5. Glass Jar A LIQUID is matter that will take the shape of any container it is placed in put has a fixed volume. Examples of LIQUIDS: 1. Water 2. Soda 3. Milk 4. Juice 5. Tomato Sauce A GAS is matter that does NOT have a fixed shape or volume, but will completely take up all the space in a container. MOST GASSES ARE INVISIBLE!!!! Examples of GASSES: 1. Oxygen 2. Helium 3. Carbon Dioxide 4. Nitrogen 5. Carbon Monoxide VIDEO http://studyjams.scholastic.com/studyjams/jams/scien ce/matter/solids-liquids-gases.htm “This concoction is an example of a suspension - a mixture of two substances, one of which is finely divided and dispersed in the other. In the case of the cornstarch quicksand, it's a solid dispersed in a liquid. When you punch the cornstarch , you force the long starch molecules closer together. The impact of this force traps the water between the starch chains to form a semi-rigid structure. When the pressure is released, the cornstarch flows again.” JOURNAL RESPONSE In five or more sentences explain what matter is and give at least two examples of each state of matter. (Include: The three states of matter and their descriptions) CLEAR LEARNING GOAL DAY 2 AS A STUDENT I WILL BE ABLE TO IDENTIFY AND CLASSIFY MATTER BASED ON ITS PROPERTIES Although matter can be classified into three different states (types) it can also be described using its properties. PROPERTIES: Characteristics, features, qualities, or traits. MATTER IS EVERYWHERE AND EVERYTHING! MATTER IS ANTHING THAT TAKES UP SPACE! Matter can be found in three different types. These three types are considered the three STATES of MATTER. 1. Solids 2. Liquids 3. Gasses LAB # 1 CLASSIFICATION AND PROPERTIES OBJECT: AIR: BLUE SUBSTANCE NUT BOLT AIR Water CLASSIFICATION (Solid, Liquid, or Gas) PROPERTIES: Looks like: Feels like: Smells Like: Sounds Like: What it Does: Looks like: Feels like: Smells Like: Sounds Like: What it Does: Looks like: Feels like: Smells Like: Sounds Like: What it Does: Looks like: Feels like: Smells Like: Sounds Like: What it Does: Looks like: Feels like: Smells Like: Sounds Like: What it Does: Looks like: Feels like: Smells Like: Sounds Like: What it Does: Looks like: Feels like: Smells Like: Sounds Like: What it Does: Looks like: Feels like: Smells Like: Sounds Like: What it Does: Looks like: Feels like: Smells Like: Sounds Like: What it Does: JOURNAL RESPONSE Now that you have finished your first lab; Choose three objects in the room that were not included in your lab. Classify them based on their state (solid, liquid, gas) and their properties (smell, looks, feels, etc.) CLEAR LEARNING GOAL AS A STUDENT I WILL BE ABLE TO IDENTIFY AND DETERMINE WHETER A CHANGE IN MATTER IS PHYSICAL OR CHEMICAL. NOW THAT WE KNOW WHAT MATTER IS AND HOW TO DESCRIBE MATTER USING IT’S *STATE (solid, liquid, or gas) and PROPERTIES(odor, texture, hardness, color) WE NEED TO SEE HOW MATTER CAN CHANGE-What ways can Matter change? Matter can go through two different types of changes. Types of Changes: 1. Physical 2. Chemical A physical change in matter is when matter changes its property but not it’s chemical nature. Physical changes: Although some properties (like shape, phase, etc.) of the material change, the material itself is the same before and after the change. The change can be “undone.” Examples: Changes in 1. Shape 2. Texture 3. Size 4. Dissolves 5. Breaks Apart EXAMPLES: Aluminum foil is cut in half Clay is molded into a new shape Butter melts on warm toast Water evaporates from the surface of the ocean Juice freezes Rubbing alcohol evaporates on your hand JOURNAL RESPONSE In six or more sentences describe what a physical & chemical change is, how you know a physical and a chemical change occurs, and three examples of both physical and chemical changes. CLEAR LEARNING GOAL DAY 4 AS A STUDENT I WILL BE ABLE TO IDENTIFY AND DETERMINE WHETER A CHANGE IN MATTER IS PHYSICAL OR CHEMICAL. A chemical change in matter is when matter becomes something completely new. New matter is formed. Chemical change: The substances present at the beginning of the change are not present at the end; new substances are formed. The change cannot be “undone." CHEMICAL CHANGES THE MATTER IS DIFFERENT. THE PARTICALES OF THE SUBSTANCES ARE BROKEN APART THE OLD MATTER IS NO LONGER PRESNT ATOMS ARE REARRANGED INTO NEW PARTICLES THE ORIGINAL MATTER A NEW SUBSTANCE IS CANNOT BE REMOVED FROM FORMED THE NEW MATTER EXAMPLES: Milk goes sour Jewelry becomes tarnished Bread becomes toast Rust forms on a nail Gasoline is ignited Hydrogen peroxide bubbles in a cut A match is lit Your body digests food Fruit decomposes and rots CHEMICAL CHANGES LAB Lab: Chemical Changes Purpose: Make a ball and observe the changes in its properties. Background information: Balls have been toys practically forever, but the bouncing ball is a more recent innovation. Bouncing balls were originally made of natural rubber, though now bouncing balls can be made of plastics and other polymers. You can use chemistry to make your own bouncing ball. 1) corn starch 2) water 3) plastic cup 4) spoon 5) white glue PROCEDURE BALL # 1 1. 2 3. 4. 5. 6. 7. Label your first cup “Borax” Add 2 tablespoons of warm water into the plastic cup labeled “Borax.” Add ½ teaspoon of borax powder in cup labeled “borax” Gently stir until powder is dissolved in the water Label a second cup “mix” Pour 1 tablespoon of glue into the cup (Add food coloring if you wish) Add ½ teaspoon borax into the “mix” cup DO NOT STI R Add 1 tablespoon of cornstarch into the “mix cup” DO NOT STI R YET 8. Wait 10-15 Seconds then mix it 9. Mix “borax cup” and “mix cup” together and mix with wooden craft stick until you can’t mix it anymore Take the mixture out of your cup and place it in your hands. I T WI LL BE M ESSY AND STI CKY 10. 11. Knead the mix to form a ball. (The more you knead, the less sticky it will become.) 12. Using a meter stick. Drop your ball from the 50 cm mark and record how high it bounces. Record your data in the table below. 13. Record your two partners data into your table as well. Observe the properties of your two partners bouncy balls.

Include an example of each change. MATTER: WHAT’S ITS WEIGHT? 5.P.2.2 Compare the weight of an object to the sum of the weight of its parts before and after an interaction. CLEAR LEARNING GOAL DAY 5 AS A STUDENT I WILL BE ABLE TO IDENTIFY AND DETERMINE THE WEIGHT OF AN OBJECT BEFORE AND AFTER A CHANGE. Every object can be described based on it’s weight. The heavier an object is the more it weigh’s. THE WEIGHT/Mass OF AN OJECT = THE SUM OF THE WEIGHT/Mass OF ITS PARTS TOTAL WEIGHT OF CAR = 2,875 LBS TOTAL WEIGHT OF PARTS= 2,875 LBS THE WEIGHT/MASS OF AN OJECT (2,875 LBS) = THE SUM OF THE WEIGHT/MASS OF ITS PARTS (2,875 LBS) 14 OZ 32 OZ 8 OZ 20 OZ 20 OZ SO HOW MUCH DOES THE CAKE WEIGH? INGREDIENTS 1. 2. 3. 4. 5. FLOUR FROSTING MILK SUGAR EGGS THE WEIGHT OF AN OJECT = THE SUM OF THE WEIGHT OF ITS PARTS INGREDIENTS = 1. 2. 3. 4. 5. FLOUR FROSTING MILK SUGAR EGGS 14 OZ 32 OZ 8 OZ 20 OZ 20 OZ TOTAL CAKE WEIGHT = 14 20 32 20 + 8 JOURNAL RESPONSE In three or more sentences determine the weight of the new object, what type of change occurred, and what state the object is in after the change. 8 OZ
