  1. 9-17-13Read the following Paragraph. What is the main idea? Find the sentence that is incorrect and correct it!! Look around the classroom. Everything, from the clothes you are wearing to the air you breathe is matter. Matter is very important. Matter makes up everything including living things like plants and people. It also makes non-living things such as tables and chairs. Things as big as an elephant or as tiny as a grain of sand on a beach are matter. Everything is matter and matter comes in three different states: solid, liquid, gas, and plasma. That means that everything is either a solid, a liquid, or a gas. Each state has properties.

  2. Agenda • Opening • Cookie Lab • Work Session • Notes on Physical and Chemical Properties • Closing • Study Jams

  3. MYP Unit Question: How can such a small thing impact our environment in such a big way? Area Of Interaction: Environment Learner Profile: Inquirer, Communicators Essential Question: How is matter described by physical and chemical properties and how does it change? Standard: Students will examine the scientific view of the nature of matter. d. Distinguish between physical and chemical properties of matter as physical (i.e., density, melting point, boiling point) or chemical (i.e., reactivity, combustibility). Learning Target: Today I am learning how to describe matter using physical or chemical properties. This is important because matters unique properties make it easier for me tell object apart.. Homework: Make Cornell Notes from your Foldable

  4. Opening- Which cookie is yours? Materials: • Cookies in a bag • Triple Beam Balance • Ruler • Pencils

  5. Procedure • Observe and list 10 different descriptions of your cookie including MASS. • Do not take the cookie out of the bag! • Do not change the cookie in any way! • Draw and color your cookie. Be detailed!

  6. Procedure cont. • Place your napkin over the cookie. • I will call on several students to describe their cookie- when you think you know which one they are describing- raise your hand. • As we are making our foldables you may eat your cookie! (please be mindful of our little (not so little) friends)

  7. Conclusions • What kinds of observations/descriptions were the most helpful in identifying the cookies? • Which were not useful and why? • Thinking about your cookies “physical properties”, list 5 physical properties of your cookie. • What is another way that we could have tested your cookies physical property without changing anything about your cookie?

  8. Matter All matter has 2 types of properties: Physical properties and chemical properties.

  9. Work Session- Foldable • Physical properties are used to identify, describe and classify matter. • Physical Property- a property that can be observed or measured without changing the matter’s identity.

  10. Malleability • The ability of a substance to be rolled or pounded into thin sheets.

  11. Physical State • The physical form in which a substance exists. • Three forms that we find on earth: liquid, solid, or gas • Temperature changes are involved with changes in state.

  12. Mass • Mass is the amount of matter in an object. Mass is measured with a balance. • Mass is not the same as weight. • Weight is a result of the pull of gravity on an object and is measured with a scale.

  13. DensitySinking & Floating • Weight doesn’t determine if an object will sink or float. • The volume of an object and how much “stuff” (matter) is in the object will determine the density.

  14. Solubility in Water • Ability of a substance to dissolve in another substance • A liquid, solid, or gas can be dissolved in water. Examples may include lemon juice in water, sugar in tea, and the carbonation in a soda.

  15. Conductivity • Some materials allow thermal (heat) or electrical energy to flow through them easily. • Conductivity is the rate at which a substance transfers heat. • Materials which easily transfer heat are called conductors.

  16. Ductility • The ability of a substance to be pulled into a wire

  17. Other physical Properties

  18. Chemical Properties • Chemical properties are characteristics involved when a substance interacts with another substance to change its chemical make-up. • A Chemical property is a characteristic of a substance that can only be observed by changing it into a different substance

  19. Reactivity • How likely the atoms of a substance are to form bonds with other substances (HUGH???) • Simply put – reactivity describes matters "potential" to undergo some chemical change or reaction when combined with something else 

  20. Combustibility • The ability to blow up

  21. Flammability • The ability to burn

  22. Chemical Properties

  23. Closing
