Presentation Transcript

  1. While you are waiting… Write the title of this unit: Chemical Interactions Then draw a picture or two of what you think of when you think of chemical interactions.

  2. Monday 8/29/11 Chemical Interactions Initial Kit Training

  3. What we will do today… • Review the scope and sequence for 8th grade • Discuss expectations for the training • Learn how the binder is organized • Participate in the early lessons • Discuss implementation strategies for the classroom • Review expectations to see whether or not needs have been met

  4. Introductions Name School you will be at this year How many years have your been teaching? How many of those have been primarily science? One thing you did this summer

  5. Today’s Language Objectives We will read and follow instructions. We will write responses and answers to questions. We will write two definitions.

  6. Agenda Scope and Sequence—20 min. Expectations—10 min. Overview of binder—15 min. Activities—2 hours Review expectations—10 min.

  7. District Scope & Sequences Aligned to state standards Timing Key Vocabulary from AESD Assessments—FOSS/Prentice Hall/ Page Keeley/Supplemental Teaching of Inquiry Skills

  8. Expectations WATT (Write And Then Talk) On the back of your cover page, write what you hope to get out of this training. When teacher cues you, discuss your expectations with your group. Whole group sharing.

  9. Binder Organization Overview Materials Investigations Masters Assessment Multimedia

  10. Mystery Mixture

  11. Step One • Put on protective eyewear • Put one 5 mL spoon of the mystery mixture into a cup. • Observe the mixture. (Do not touch or taste the mixture.) • Record your observations in the Step One box.

  12. Step Two • Add one drop of water to the mystery mixture in the cup. • Take turns adding additional drops of water to the cups. Observe the mixture. • Record your observations in the Step Two box.

  13. Questions • What happened when you added one drop of water to the mixture? • What happened when you added a second drop? • Did it fizz and bubble every time you added a new drop of water? • What causes the bubbling and fizzing? • Why does the mixture stop fizzing after five pipettes of water have been added?

  14. White Substance Information

  15. White Substances A substance is a form of matter. There are millions of different substances on Earth. Each substance is different from every other substance.

  16. Vials 9 different vials containing white substances Each vial has a different substance…no mixtures. Two of these make up the Mystery Mixture. Your job is to determine which two.

  17. Researching the Substances

  18. Mystery Mixture Analysis

  19. Do you know which two make up the Mystery Mixture? What could you do now to test your hypothesis?

  20. Which two substances make up the Mystery Mixture? What evidence do you have to support your conclusion?

  21. 7 combinations that produce bubbles Ascorbic acid + calcium chloride Ascorbic acid + sodium bicarbonate Ascorbic acid + sodium carbonate Calcium chloride + sodium bicarbonate Citric acid + calcium carbonate Citric acid + sodium bicarbonate Citric acid + sodium carbonate

  22. What we already know… A substance is a form of matter with unique composition and distinct properties. Substances can be represented with common names, chemical names, and chemical formulas.

  23. Reaction discussion When you added water to the mystery mixture, bubbles were produced. What are bubbles? Was the gas always there and just came out when water was added to the substances? Where did the gas come from?

  24. Chemical Reactions The gas formed as a result of a chemical reaction. During a reaction, starting substances change into new substances. Change is evidence of a reaction.

  25. Chemical Reaction Questions Do you think the two substances in the mystery mixture reacted when water was added? What is your evidence? Besides gases being created, what other changes might indicate a reaction has happened?

  26. Conclusion Is everyone 100% certain they know what the two substances are that make up the Mystery Mixture? Is there anything else we could do to get closer to being absolutely certain about which two mixtures make up the Mystery Mixture?

  27. Vocabulary—Group Work • How would you define the following words? • Substance • Chemical reaction

  28. Mystery Mixture Claim and Evidence Organizer Claim: Which two substances make up the mystery mixture? Evidence: Identify all of your observations that support your claim.

  29. Summary Paragraph • Write a paragraph that states your claim and identifies 3 lines of evidence. • Indent • Capitalize • Punctuate • Complete sentences • Spelling

  30. Periodic Table of the ELEMENTS • Which ones do your recognize? • Elements are building materials of matter. • Everything on Earth that has mass and occupies space is made of combinations of these elements. • All substances are made of elements.

  31. Elements Reading • What is an element? • How are matter and elements related? • How was Mendeleyev able to predict the existence of elements that had not yet been discovered?

  32. What is an element? • How are matter and elements related? • How was Mendeleyev able to predict the existence of elements that had not yet been discovered?

  33. Elements in Products

  34. All matter is made of elements. We come in contact with a lot of different forms of elements every day. What elements do you think they are made of? • Read the ingredients list on 5 different labels. • Record any elements you find. • Then answer questions 1-3.

  35. Elements in the Universe
