  1. Warm up If you mix two chemicals and one of them already has a color, How can you tell if a reactIon occurs or not?

  2. Warm up answers Look for the formation of a precipitate (solid)

  3. question What are the products of the following reactions? A. Copper Sulfate with Silver Nitrate B. Copper Sulfate with Lead Nitrate C. Copper Sulfate with Calcium Chloride

  4. hypothesis Learn a little about each chemical before you make a hypothesis

  5. Background information Copper Sulfate http://en.wikipedia.org/wiki/Copper(II)_sulfate Lead Nitrate http://en.wikipedia.org/wiki/Lead(II)_nitrate Silver Nitrate http://en.wikipedia.org/wiki/AgNO3 Calcium Chloride http://en.wikipedia.org/wiki/Calcium_chloride Now make your hypotheses (plural of hypothesis)

  6. methods Mix the chemicals together

  7. results Record your observations in a data table. Draw a picture (or use a photo), and write a description

  8. conclusion A. no visible reaction B. Pb(NO3)2 + CuSO4 PbSO4 (s)+ Cu(NO3)2 C. CaCl2 + CuSO4 CaSO4 (s) + CuCl2

  9. Cool down Explain why the chemicals reacted with (or did not react with) each other What is a creative way you could apply what you learned in class today?
