  1. General Chemistry Bell Ringers

  2. Bell Ringer • Pick Up Your Copy of the Syllabus and briefly scan it. You will need to be ready to discuss 3 Questions OR Comments you have written down. At this time your Bell Ringer will be written on scratch paper or in the margin of your syllabus. You will not be turning them in for a grade but are expected to share our 3 items as part of class discussion.

  3. Bell Ringer Today is the District Pretest. You will need to pick up an LXR sheet and begin filling in the following information IN PENCIL Name: Period: Class: Honors Chemistry Test: District Chemistry Pretest Instructor: Mrs. Senger Identification Number: Write and Bubble C1 Bubble your period # Example: 2, 3, or 4 C2 is my teacher code: 6L

  4. Bell Ringer Our First Learning Log Entry! Have your composition note book open to first page to begin Table of Contents Name 1 Period # General Chemistry Page Content 1 Table of Contents Example: BR 9/9 3-4 Section 1.1

  5. Describe the classification of matter for water and for oxygen. You might find the image above helpful as well as the flow diagram on page 42 of your book.

  6. Measurements Lab Day! Have your Composition Notebook out for Labs (NOT the same as Learning Log) Begin your log for the Table of Contents Name 1 Period # General Chemistry Lab Book Page Content 1 Table of Contents Measurements Lab

  7. Bell Ringer Have your Lab Notebooks out for a quick check to make sure you are ready to continue with data collection.

  8. Bell Ringer Paul tells his friend that the sun rising in the east and setting in the west is a theory. Julie tells him that he his wrong. Defend Julie’s reasoning for stating that Paul’s statement is false.

  9. Copy the Flow Chart Below into your 9/15 Bell Ringer Entry. Answer: What classification of matter is table salt (NaCl)? Classification of Matter

  10. Learning Log Exit Question Before you leave today, write one question you could ask about the content we studied today. The question should be either short answer and can begin with words like explain, predict, evaluate, or compare. Avoid questions that simply ask for a list. Write them on a sheet of paper to be handed in as you leave the classroom.

  11. Bell Ringer Pick up your Exit Question from yesterday. Trade your question with the partner at your table. If your partner is absent then find another person that is solo to switch with. Solve their question in your learning log for today’s Bell Ringer

  12. Classify each of the properties below as either a Chemical or Physical Property and discuss the your logic in identifying which property they belong to. Substitute Here…Did not use this slide Properties of Matter

  13. a. A. A chemical change B. Cannot determine without additional information C. Neither a physical nor a chemical change D. A physical change

  14. b. A. A chemical change B. Cannot determine without additional information C. Neither a physical nor a chemical change D. A physical change

  15. c. A. A chemical change B. Cannot determine without additional information C. Neither a physical nor a chemical change D. A physical change

  16. Describe the classification of matter for water and for oxygen. You might find the image above helpful as well as the flow diagram from our Bell Ringer on Sept 15th or page 42 of our book.

  17. Chapter 1 Quiz • Chapter 1 Learning Logs are due…Place in the basket for grading • You will be taking the team test found on page 47 as a review for this chapter. Please have a piece of paper out ready to participate when I give you your Clock Partner for today.

  18. Separation of a Mixture Lab Day! Have your Composition Notebook out for Labs Make the entry in the Table of Contents • Name 1 • Period # • General Chemistry • Lab Book • Page Content • 1 Table of Contents • Measurements • Lab • 3 Separation of a • Mixture

  19. Bell Ringer You will be continuing your lab on Separation of Mixtures. BEFORE you can begin, your lab must be checked to ensure that it has the following parts: Questioning: Predicting: Procedure: Safety:

  20. Bell Ringer This is your final day of the Separation of Mixtures Lab. Be seated and ready for attendance before finishing your lab write ups. Remember that your final sections should have the following parts: Data & Observations: Calculations & Results: Discussion of Results: Additional Questions:

  21. Bell Ringer Make a T-Chart On the left side write any sample from below that is a pure substance. On the right side write any sample that is a mixture. Blood, Banana Split, Granite, Air, Water, Tap Water, Sugar, Peanut Butter, Copper, Carbon Monoxide and Gatorade

  22. Bell Ringer Write one complete sentence with a WHY you think that way… What element makes up half the Earth’s crust, oceans and atmosphere? This element is also the most abundant element in the human body. No peeky in the book for answers…or Siri or other Siri wantabe

  23. Bell Ringer Write the chemical names for: Fe Au K Write the chemical symbols for: Lead Silver Calcium

  24. Bell Ringer We know that for every water molecule there are 2 hydrogen atoms and 1 oxygen atom. Which of Dalton’s Theory rules does this apply to? Don’t just tell write the number. Explain why it fits that rule.

  25. Bell Ringer Complete the chart below:

  26. Bell Ringer Convert 35 hours to seconds and show all work!

  27. Bell Ringer Label the provided Periodic Table with the titles: Alkali, Alkaline Earth, Transition, Halogen, Nobel Gas, Lanthanides and Actinides. Use page 69 as reference if needed. Next, mark your metalloids (semiconductors) in their distinct stair step pattern.

  28. Bell Ringer Copy and Complete the Chart Below into your Learning Log. Feel free to use Section 3.5 for reference if needed.

  29. Bell Ringer Your Learning Log for Chapter 3 is due tomorrow! Please take 3 minutes to refer to the Document Camera image and double check that your log is complete. If you are missing ANY of these items…Get them fixed tonight to earn full credit!!!

  30. Bell Ringer If you were provided with A Z What would A, Z and X stand for?

  31. Bell Ringer You will need this whole period to take the Chapters 1,2 & 3 Exam… You may use scratch paper if needed or a calculator but NOT a cell phone. Please pick up your remote and be ready to begin. Good Luck!!!

  32. Percentage of Water Lab Day! Have your Composition Notebook out for Labs Make the entry in the Table of Contents • Name 1 • Period # • General Chemistry • Lab Book • Page Content • 1 Table of Contents • Measurements • Lab • 3-5 Separation of a • Mixture • 6-9 Percentage of • Water
