Today we will explore chemical reactions and watch some demonstrations. The five pieces of evidence that prove that a chemical reactions took place are:
  1. Bubbles form- a gas is given off
  2. A color change occurs
  3. A precipitate is formed-a solid substance is formed from two or more liquids
  4. Energy change
  5. A new substance is formed (all chemical reactions need this piece of evidence)
Please try the Standards Check questions found here.

Today we learned the wonders of distillation. Here is a picture of the results from our distillation of grape juice. Many students were surprised when I poured clear water from the bowl in the pot.

Look how dark the liquid that was left at the bottom of the pot is. Is this liquid the solvent or the solute?
