  1. MATTER Elements, Compounds & Mixtures DAY ONE

  2. EQ: What are solutions, colloids, and suspension?TIWL: about solutions, colloids, and suspensions, because they are all mixtures. JOURNAL WRITING (DIRECTIONS) • ANSWER WRITING PROMPT • PLACE IN JOURNAL SECTION • STUDENTS WILL SHARE RESPONSES (QUESTION) Define a mixture in your own words & draw 2 examples (examples: salad, trail mix etc.) Students can refer to the textbook if needed.

  3. Content STANDARD & ELEMENT STANDARD S8P2 : Students will examine the scientific view of the nature of matter. describe the difference between pure substances (elements and compounds) and mixtures. Element (b)

  4. Language of the Standards(Today's Vocabulary) Elements Compounds Mixtures Solutions Colloids Suspension Mixtures Physical Change Chemical Change

  5. ESSENTIAL QUESTION • What are mixtures (solutions, colloids and suspensions? 2. How do we differentiate between elements, compounds & mixtures?

  6. WHY IS THIS IMPORTANT ? Today I will ……. THIS IS IMPORTANT BECAUSE...... learn how to differentiate between SOLUTIONS, COLLOIDS & SUSPENSIONS. because they are all MIXTURES.

  7. ACTIVATOR DIRECTIONS : • LISTEN TO THE “SMASH-SONG/ VIDEO” from Glee Club • IDENTIFY THE MIXTURE OF SONGS

  8. MIXTURES The Learning Period

  9. Elements • All elements are made of atoms. • Atoms of the same element are alike. • Atoms of different elements are different.

  10. Compounds • Compounds are also pure substances. • But compounds are made from more than one element. • Water is a compound. • Water can be broken down into simpler substances – hydrogen and oxygen.

  11. A mixture is a combination of two or more substances where there is no chemical combination or reaction. www.brainybetty.com

  12. Mixtures combine physically in no specific proportions. They just mix. www.brainybetty.com

  13. Mixtures are classified as: HOMOGENOUS/HETEROGENOUSSOLUTIONSCOLLOIDSSUSPENSIONS www.brainybetty.com

  14. COLLOIDS

  15. Colloids • In a colloid the particles are mixed together but not dissolved. • The particles are relatively large and are kept permanently suspended.

  16. Colloids • A colloid will not separate upon standing. • The particles are constantly colliding, and this allows a colloid to scatter light – thus colloids often seem cloudy.

  17. Heterogeneous Mixtures (cont.) Colloids are heterogeneous mixtures of intermediate sized particles (between 1 nm and 1000 nm) and do not settle out. • Colloids are categorized according to the phases of their particles.

  18. Heterogeneous Mixtures (cont.) Section 14-1

  19. SOLUTIONS

  20. Solutions • A solution is a type of homogeneous mixture formed when one substance dissolves in another. • It is the best mixed of all mixtures. • A solution always has a substance that is dissolved and a substance that does the dissolving. • The substance that is dissolved is the solute and the substance that does the dissolving is the solvent.

  21. Ocean water is a solution

  22. The universal solvent: Water

  23. Water as a solvent • Many liquid solutions contain water as the solvent. • Ocean water is basically a water solution that contains many salts. • Body fluids are also water solutions.

  24. Types of solutions Solute Solvent Example

  25. Air is a solution of oxygen and other gases dissolved in nitrogen

  26. Homogeneous Mixtures (cont.) Section 14-1

  27. SUSPENSIONS

  28. Suspension- a heterogeneous mixture in which the particles are large enough to be seen by a microscope or the unaided eye (eventually, they settle out of the mixture). Example: stirring a teaspoon of dirt in a glass of water.

  29. CLASSWORK Directions: create a Triple Venn Diagram, or 3 Column T-chart to learn about the new vocabulary words. Each circle/chart needs to have 3 keys points, and 2 examples. • Solutions • Colloids • Suspension • Mixtures • Elements • Compounds

  30. TRIPLE VENN DIAGRAM ELEMENTS MIXTURES COMPOUNDS

  31. 3 COLUMN T-CHART MIXTURES COMPOUNDS ELEMENTS

  32. Closing USE A POST-IT & PLACE ON THE SPECIFIED GRAPHIC ORGANIZER Share some examples of your mixtures out loud with a partner and then with the class.

  33. HOMEWORK REMINDERS ………. STUDY FOR THE QUIZ !!!!! STUDY ALL NOTES INCLUDING YOUR STUDY GUIDE!

  34. MATTER Elements, Compounds & The Periodic Table DAY TWO

  35. S8P1b. • If different kinds of atoms are represented by different colored dots, which picture below represents a mixture? SPONGE DIRECTIONS: 1) ANSWER THE QUESTION 2) REVIEW THE STUDY GUIDE BEFORE THE QUIZ . a. b. c. d.

  36. 2. Which of the following is a compound ? • Oxygen • Carbon • Water • None of the above 3. How many atoms are in CO2 ? a. 1 b. 2 c. 3 d. 4

  37. Content STANDARD & ELEMENT STANDARD S8P2 : Students will examine the scientific view of the nature of matter. describe the difference between pure substances (elements and compounds) and mixtures. Element (b)

  38. Language of the Standards(Today's Vocabulary) Elements Compounds Mixtures Solutions Colloids Suspension Mixtures Physical Change Chemical Change

  39. ESSENTIAL QUESTION • What are mixtures (solutions, colloids and suspensions? 2. How do we differentiate between elements, compounds & mixtures? 3. How do I assess what I have mastered from the nature of matter unit?

  40. WHY IS THIS IMPORTANT ? Today I will ……. THIS IS IMPORTANT BECAUSE...... assess what I have learned about matter. it is important for me understand what standards I have mastered.

  41. ACTIVATOR

  42. WE ARE TESTING !!!!!

  43. SOCRATIC SEMINAR Directions: WE will participate in a Socratic seminar over the article. This is a dialogue discussion. Students will get a ticket. Their ticket is their way into the conversation. Students must keep the conversation advanced.

  44. Closing Today I felt about the quiz…… Use the subatomic particle faces to describe what you feel your performance on the quiz was:

  45. Name: Elliott Electron Description: Negative Favorite Activity: Racing around the arcade

  46. Name: Patty Proton Description: Positive Favorite Activity: Hanging out at the Nucleus Arcade Name: Nelda Neutron Description: Neutral Favorite Activity: Hanging out at the Nucleus Arcade

  47. HOMEWORK REVIEW WHAT WE HAVE LEARNED TODAY
