Presentation Transcript

  1. Welcome ! CAPT Physical Science

  2. What is an ACID? AnACID is a Compound that has Hydrogen at the Beginning of its formula Examples of Acids: HCl H2SO4 HNO3 • Here’s what you should know about acids: • Can burn your skin • React with metals • Can damage building materials What's a BASE ? - Opposite of an ACID - Used to Neutralize and ACID - Formula ends with -OH

  3. How do we Measure ACID or BASE ? pH Scale

  4. BASES ACIDS vs. Let's Sort These: Lemon Juice Alka-Seltzer Orange Juice Vinegar Calcium Carbonate (TUMS, Rolaids) Baking Soda

  5. BASES ACIDS vs. Let's Sort These: Alka-Seltzer Lemon Juice Calcium Carbonate (TUMS, Rolaids) Vinegar Baking Soda Orange Juice What is ACID RAIN ?

  6. When pollutants combine with water they make acid rain, rain that is acidic (pH<5.5) ACID Rain

  7. What are some environmental concerns with Acid Rain?

  8. Acid Rain Lab Lab Discussion & Analysis How is the type of building material affected by acid rain? What is the Independent Variable? What is the Dependent Variable? What should be Controlled in this experiment?

  9. Acid / Base Review

  10. Acid / Base Review

  11. Polymers "Plastics" What are some Advantages of using Polymers? Strong Light Weight Flexible Lots of variety TENSILE STRENGTH

  12. Cross-Linking Cross-Linking increases the strength of the Polymer

  13. Recycling Codes
