* Chapter 10 :Foundations of chemistry Lesson 1: classifying matter Objective: Observe how does the classification of matter depends on atoms Matter Anything that has mass and takes up space. Also things we cannot see Example: Water, tree and air
* Chapter 10 :Foundations of chemistry Lesson 1: classifying matter Objective: Observe how does the classification of matter depends on atoms Atom Small particles that is the building block of matter Matter around you,including all solids,liquids and gases
* Chapter 10 :Foundations of chemistry Lesson 1: classifying matter Objective: Observe how does the classification of matter depends on atoms Substance. Is a matter with a composition that is always the same. Always contains the same kinds of atoms in the same combination
* Chapter 10 :Foundations of chemistry Lesson 1: classifying matter Objective: Observe how does the classification of matter depends on atoms Type of Substances: Elements Compound
Lesson 1: classifying matter Objective: Observe how does the classification of matter depends on atoms Elements: Substances made of only one kind of atom All atoms of an element are alike,but atoms of one element are different from atoms of other elements HAS ONE TYPE OF ATOM
* Chapter 10 :Foundations of chemistry Lesson 1: Classifying Matter Objective: Observe how does the classification of matter depends on atoms Compound: Substances made of two or more elements that are chemically joined in a specific combination HAS ONE TYPE OF PARTICLE
* Chapter 10 :Foundations of chemistry Lesson 1: classifying matter Objective: Observe how does the classification of matter depends on atoms Mixture: 1- Is a matter that can vary in composition. 2- It is made of two or more substances that are blended but are not chemically bonded
Lesson 1: classifying matter Objective: Observe how does the classification of matter depends on atoms Example of Mixtures:
Lesson 1:classifying matter Objective: Observe how does the classification of matter depends on atoms Types of Mixture: 1- Heterogeneous: mixture in which the substances are not evenly mixed(visible differences between substances) Mixed of Mixed of different minerals Raising, nuts,pretzels from which it is made
* Chapter 10 : Foundation of chemistry Lesson 1: classifying matter Objective: Observe how does the classification of matter depends on atoms Types of Mixture: 2- Homogeneous: mixture in which two or more substances are evenly mixed(no visible differences between substances) Mixed of ethane, Mixed of methane, Solid copper and solid zinc and other gases
Lesson 2: Physical properties Objective: Identify physical properties of a matter Physical properties: Is a characteristic of matter that you can observe or measure without changing the identity of a matter
* Chapter 10 :Matter and Atoms Lesson 2: Physical properties Objective: Identify physical properties of a matter Examples of Physical properties: Mass: the amount of matter in an object Conductivity: The ability of matter to conduct,or carry electricity or heat Volume: The amount of space something occupies Boiling / Melting point: The temperature at which a material changes state
* Chapter 10 :Matter and Atoms Lesson 2: Physical properties Objective: Identify physical properties of a matter Examples of Physical properties: State of matter: whether something is a solid,liquid or a gas Density: The amount of mass per unit of volume Solubility: The ability of one substance o dissolve in another Magnetism: Attractive force for some metals, especially iron
Lesson 3: Physical changes Objective: Identify how matter changes without loosing their identity Physical changes: Is a change in size,shape, form, or state of matter in which the matter s identity stays the same.
Lesson 3: Physical changes Objective: Identify how matter changes without loosing their identity Examples of changes in size and shape: 1- Chewing food : This change in size helps make food easier to digest. You are breaking it into smaller pieces. 2- Pouring juice: When you pour juice from a bottle into a glass. The liquid changes the shape.
Lesson 3: Physical changes Objective:Identify how matter changes without loosing their identity Examples of changes in state and dissolving: 3- Change in state of matter : When ice melts or the liquid is heated. Adding thermal energy (from solid to liquid) and removing thermal energy (from liquid to solid) Thermal energy means amount of energy absorbed by a body. 4- Dissolving: When you added salt to the water of the aquarium.
Lesson 4: Chemical properties and changes Objective:Identify the type of matter that can change chemically Chemical properties: Is a characteristic of matter that can be observed as it changes to a different type of matter. The ability of a susbtance to burn Example: The paper can burn and change into another substances(ashes).
Lesson 4: Chemical properties and changes Objective:Identify how to change a matter into another by changing its identity Chemical changes : Is a change in matter in which the substances that make up the matter change into other subsatnces with new physical and chemical properties. Example: When iron undergoes a chemical change with oxygen,rust form.
Lesson4 : Chemical properties and changes Objective: Identify how to change a matter into another by changing its identity Some signs of Chemical change : Bubbles Energy change Odor change Color change
Lesson 4: Chemical properties and changes Objective: Identify how to change a matter into another by changing its identity Signs of chemical change : It is important to know that these signs do not always mean a chemical reaction change ocurred. Example: When we heat water in the stove the bubbles develop but the water is not changing chemically but physically.
