  1. Texas A&M E3 Summer Research Program Welcome to the City of Brumbellville: The Virtual City That Becomes A Reality Karina Monteal & Gregory Washington June 28, 2007

  2. Topics… • The question • General lesson plans & • Objectives • The Initial Virtual Model • Brumbellville’s Layout • The Lesson(s) • Conclusions • Acknowledgements

  3. THE QUESTION IS: After someone tampered with the city water reservoir is the water safe to drink? ACIDIC or BASIC?

  4. General Objectives: • To discuss various solvents, their salvation power. Solvent, solute, solubility relation. • To discuss pH in terms where the pH= –log (H+)

  5. Specific Objectives: • IPC.08.B, C, E: Understand chemical reaction. Balance chemical reaction. • IPC.09.A, D, E: Understand Physical and chemical properties of solvent and solution. • IPC.09.A: Understand ionic concentration in solution. Make a Venn diagram of acid, base and salt. Vocabulary words and their definitions. Discuss acids, base and their uses. Discuss common bases. • Hands on activity- how to distinguish acid and base (litmas reaction). Dissociation of acid /base solution, concept of hyronium (H3O+) and hydroxyl (OH-) ion. Why H+ ion cannot exist in solution? • Students will be able todiscuss strong acid and strong base. Hands on activity of electric conductance of strong acid and base solution. Introduce concept of pH , pOH, Kw of water. Discuss natural pH indicator.

  7. BRUMBELLVILLE LAYOUT OF THE CITY COMING TO LIFE

  8. THE ACTUAL MODEL OF BRUMBELLVILLE

  9. ACIDs AND BASES

  10. ACIDS AND BASES ARE EVERYWHERE

  11. ACIDS AND BASES ARE EVERYWHERE • Liquid solutions would be either and an acid or base. • Exception would be the solvent distilled water. • Distilled water is just water. • Ions in solution make something acidic or basic.

  12. ACID AND BASES ARE EVERYWHERE… • In your body there are small compounds called “amino acids”. Those are acids.

  13. ACIDS AND BASES ARE EVERYWHERE… • “citric acid”

  14. Q: But what about baking soda? A: When you dissolve it in water, a solution of baking soda will be a base. NaHCO3

  15. Q: What about vinegar? • A: Vinegar, it’s an acid

  16. Q: What about the: -coffee you drink? -Soda? -cleaning stuff you use? -juice?

  17. Let's find that out!

  18. The pH Scale • Water has a pH of 7, right at the middle, and it is neutral. • Acids are found between 0 to 7. • Bases are between 7 to 14. • Most of the liquids you find every day have a ph near 7.

  19. ACIDS • Taste sour. • Corrode metals and other substances • Burn your skin if strongly concentrated • All acids no matter how dilute, can damage your eyes and other areas of your body. Household Acids

  20. BASES • Taste bitter • Slippery • Can be very dangerous if ingested or in contact with the skin Household Bases

  21. Do you want to know how acidic or basic the substances you commonly drink or deal with are? Well, why not try the activity we have here?

  22. Are you Ready? Put your… Goggles, Gloves, Apron, And let’s start!!!

  23. ACIDS AND BASES Introduction: • You can determine if a substance is an acid or base by using an indicator. • An indicator will change colors when combined with an acid or a base. • The color of the substance determines the pH.

  24. ACIDS AND BASES Materials: beakers lemon juice milk coffee soda pH paper vinegar creamer ammonia liquid cleaner antacid bleach

  25. ACIDS AND BASES Procedure: • Obtain a beaker of each of the solutions and dip a one-inch piece of pH paper into one of the solutions. • Compare the color of the ph paper to the pH indicator. • Repeat steps 1 and 2 to each of all the other solutions. • Complete the Data table.

  26. Data Table:

  27. Have you learned something today?

  28. THANK YOU FOR JOINING US AND HAVE A NICE DAY!!!

  29. ACKNOWLEDGEMENTS THE MAN OF THE HOUR: DR. KELLY BRUMBELOW DR. BUTLER-PURRY Ph.D. CANDIDATE: JULIANNA CAMACHO Ph.D. CANDIDATE: JACOB TORRES THE BEST PARTNER IN THE PROGRAM: KARINA MONTEAL OH AND YOU KNOW I CANNOT FORGET YOU ALL: THE E3 CLASS OF 2007!!!
