  1. Do Now for 9/16/13 Open your Composition book to the first clean page. HW: Safety Project due Wednesday, 9/18

  2. A6 Identifying Liquids • Today’s Target: To learn how to properly write up a lab report and prepare for an activity. • Safety Project – Worth a quiz grade • Introduce A6 • Reading the activity • Write up A6 according to a specific format • Lab responsibilities

  3. Safety Project • Safety Project • (quiz grade) due Wednesday • Choose one of the following formats to complete this project: • Poem (minimum of 15 lines) • Essay (minimum of 2 paragraphs) • Mini Poster (8 x 10 piece of computer paper) • Story (minimum of 2 paragraphs) • PowerPoint or DVD of a safety situation. • Be sure to include the following information in your project regardless of the format you choose: • The safety statement (copied from your safety contract) • An appropriate scenario or situation when the safety precaution applies. • What to do in order to follow the safety precaution. • What might happen if the safety precaution is not followed.

  4. Working together in the lab • Group Responsibilities • Place this copy in your folder/binder.

  5. Proper Goggle Storage

  6. Improper Goggle Storage

  7. A6 Identifying Liquids – Reading for understanding. • Read the Title and Background. • Read the Challenge and think about how it relates to the background, and what we have previously done in class. • Read the steps in proper order. • Read each step carefully – DON’T SKIM THE TEXT! • As you read each step, imagine yourself completing it. • Write the number of steps you don’t understand and some questions you have about each step.

  8. A6 Identifying Liquids • Top Line of Page - Title: A6 Identifying Liquids • Skip a line • Challenge: - What are the liquids in the mixture? • Skip a line • Safety: - Wear safety goggles while working with chemicals. Clean up any spills immediately. Do not touch the mixture, or any part of it, and do not bring it into contact with your eyes or mouth. Wash your hands after completing the activity. • Skip a line • Procedure: I have read and understand the procedure. • OR • I do not understand step(s)

  9. Do Now for 9/17/13 • Take out write up for A6 • HW: Safety contract signed • Safety project due tomorrow

  10. A6 Identifying Liquids • Today’s Target: To identify the two (2) liquids from an unknown mixture. • Introduce A6 • Review lab safety • Gather data • Clean up

  11. A6 Identifying Liquids • Read background on page A-21 • Draw the data table on page A-24 • Lab safety – Goggles and aprons; wash your hands • Clean your tray before using it. • Work in groups of 2 • One group tests liquid A • The other group tests liquid B • Carry out each of the tests on your liquids (See page A-23). • Use the dropper to get ONLY the liquid you are testing. • Complete the data table on page A-24.

  12. A6 Identifying Liquids • Clean up • All liquids from the vials goes in the waste container and the front of the room. • Wash and dry all equipment using soap and water. • Wash and dry the station using soap and water. • Place fresh paper towels on the tray. • Arrange all the equipment neatly. • MAKE SURE THE CAPS ARE ON THE LIQUIDS AND THE CORRECT DROPPERS ARE ON TOP. • Wash your hands.

  13. Exit Ticket • Take out a 3x5 card and put your name, today’s date, and this period in the upper right hand corner. • Answer the following question on your card: • Do you think THE ORIGINAL MIXTURE was toxic and why? • DUE AT THE END OF THE PERIOD!!!

  14. A6 Separating Liquids • Do Now for 9/18/13 • Take out write up and data for A6 • HW: Complete EXPANDED ANSWER # 1 for A6

  15. A6 Separating Liquids • Today’s Target: To identify the two (2) liquids we were able to separate from our unknown mixture. • Do you think THE ORIGINAL MIXTURE was toxic and why? • Collect project • Review data • Discuss analysis • Rubric for #1 • Expanded answer for #1

  16. A6 Separating Liquids – Our data

  17. A6 Separating Liquids –Actual data

  18. A6 Separating Liquids • Use the data and the table on page A-25 to identify the liquids. • Answer Analysis 1,2,

  19. Expanded Answer – Worth MORE than a test grade!!! • Expanded answers are an example of your BEST work. • You explain what you think and WHY you think that. • You use EVIDENCE to support your answer. • A6 Number 1 rubric • Write an expanded answer for #1. DUE TOMORROW

  20. **Grading*** 4= 95 3=80 2=70 1=60 3 2 1 Total: Divide by 3:

  21. *** The only way you can get a 4 (95%) is to get all 3’s on the top portion. If you have a 2 or a 1 then you are unable to do the bottom half . • For right now, to make a 4 you will only need 1 yes in the second box. Later on in the year you will be asked to have 2, 3, or 4.

  22. Bonus: • Anyone and everyone is capable of getting the bonus. There is not a minimum or maximum requirement. • To get a 100%- you must have all 3’s on top, at least 1 yes on the bottom, and a good opening and closimg. • The highest one can make is a 105% (All 3’s on top, at least 1 yes on the bottom, a good opening and closing, and type your answer)

  23. Level 1: Bad science- 1 week to revise and resubmit -65% • You identify evidence and or • You explain what you think the evidence means • Level 2: Good science; need more info-75% • You explain what you think the evidence means. • You use some evidence to support your ideas. • Level 3: Good science; info is complete-85% • You use evidence to support a logical interpretation of the data. • You evaluate the source, quality, and/ or quantity of evidence. • Level 4: Great Science -95% • You accomplish level 3 and go beyond in some significant way such as: • You present thorough examination of evidence • You connect your ideas with the science concepts learned. • You provide an explanation for why alternative ideas were discarded. • You provide suggestions for further relevant investigations • You include a diagram or visual to clarify your ideas.

  24. Exit Ticket • Take out a 3x5 card and put your name, today’s date, and this period in the upper right hand corner. • Answer the following question on your card: • Would you feel safe pouring this mixture down the drain? Why or why not? • DUE AT THE END OF THE PERIOD!!!

  25. Do Now for 9/19/13 • Take out A6 #1 and your rubric • HW :Safety quiz on Monday • Scientific Method Song

  26. A6 Separating Liquids • Today’s Target: To develop an answer to the analysis questions that are correct and use evidence to prove I am right. • Expand and peer edit #1 • Revise #1

  27. Final analysis report A6 #1 Work on your final copy of analysis #1 from A6 When finished hand to a peer to review use the white feedback form to grade your peer. (Edit and re-write)

  28. A6 Separating Liquids - Vocabulary • Toxic -A4 • 1. Chemical property: A specific result of a test with a chemical reagent. Chemical properties include pH, the production of a salt when an acid reacts with a metal, or a unique color change in a chemical reaction. • 2. Miscible: Two or more substances that can be mixed together in any ratio to form a single phase without separation. • 3. Physical property: A characteristic of a substance or material, such as color, density, flexibility, hardness. These properties help identify pure substances and never change whether there is a large sample or very small sample of material. They are intrinsic properties.

  29. A6 Separating Liquids • Key Concepts: Write these down and give an example from the previous activities where this is shown. • Substances have characteristic properties such as density, that are independent of the amount of the sample. • Ex. No matter how much or how little we have, Liquid B will always float on top of Liquid A. • Scientists use appropriate tools and techniques to gather, analyze, and interpret data. • Ex. pH paper is used to tell if something is corrosive. • Scientific explanations emphasize evidence. • Ex. We are determining what liquid A and B are based on their characteristics, NOT by guessing.

  30. A6 Lab Check • Title, Challenge, Safety – 5 points • Data Table with data – 5 points • All Analysis questions answered – 5 points • Additional Worksheets • Key Points with examples – 5 Points • Total = 25 points
