Presentation Transcript

  1. Physical and Chemical Properties 7th Grade Notes/Lecture pgs. 594-596

  2. Do Now Together… (with your lab group) • Imagine you are at a fair/carnival. Describe what you are experiencing with your senses (see, touch, taste, hear and smell.) • Check True/False Activity

  3. Objectives Students will… • Identify physical and chemical properties of matter • Classify objects based on physical properties

  4. Physical Properties • A physical property is a characteristic that you can observe without changing or trying to change the composition of the substance. • Examples of physical properties might be how something looks, smells, sounds or tastes. (Use your senses!)

  5. Physical properties • To describe a sample of matter, you need to identify its state. (solid, liquid, gas). Name some examples of each state of matter.

  6. Physical Properties foldable for notes • We will be creating a foldable describing the physical properties of matter. • Create foldable according to teacher instructions. • Physical Properties fall into 2 categories: Size-Dependent and Size-Independent.

  7. Size dependent properties • Size-Dependent Properties rely on the size of the object. ( 3 properties) • 1) Volume: the amount of space in an object • 2) Mass: the amount of matter in an object • 3) Weight: depends on the mass and the strength of gravity

  8. Size-Independent Properties • Size-Independent Properties DO NOT rely on the size of an object. (7 properties) • 1) Density: the amount of mass in a given volume • 2) Solubility: amount of a substance that will dissolve another substance • 3) Melting point: temperature at which a solid changes into a liquid

  9. Size-Independent Properties • 4) Boiling Point- temperature at which a liquid turns into a gas • 5) State of Matter- whether a substance is a solid, a liquid or a gas. • 6) Magnetic Properties: can or cannot attract a magnet • 7) Color: wavelength of light reflected

  10. To Review • Properties of Matter • For Next Time… • Test signed by tomorrow • Bring in one or two objects from home that can be used to describe physical properties of matter • Examples: a book, toy, figurine, food wrapper etc…

  11. Physical and Chemical Properties 7th Grade Notes pgs 597-598 Physical Properties activity

  12. Do now… • Describe the physical properties of a baseball. (Hint: state, shape, texture, color, mass etc…) Properties of Matter

  13. objectives • Students will… Identify physical properties of certain substances Explore chemical properties of matter Describe physical properties of known everyday objects

  14. Physical Properties of Specific Substances

  15. Chemical Properties • Chemical Properties are characteristics that cannot be observed without alternating or changing the substance. • It is the ability of a substance to undergo a change the alters its identity.

  16. Physical Properties of objects

  17. For Review • Physical vs. Chemical Properties • For Next Time… • Each lab group needs to bring in for lab on Monday: egg, piece of fruit, a vegetable, baggie of dry cereal and a slice of bread. (divide up among members!)
