Sort your vocabulary words into 2 categories: H2O and oxygen word bank: chemistry formula element physical change atoms molecule chemical change compound chemical reaction symbol chemical bond mixture

Word Sort Two categories- H20 and Oxygen Write each down on your paper in two columns Place the following words in the categories that they belong: chemistry, atoms, compound, symbol, formula, molecule, chemical bond, element

example H20 oxygen atom s atoms

Color Code Go back over your list and color the words that are the same H20 chemistry atoms compound symbol formula molecule chemical bond oxygen chemistry element atoms when 02, molecule when 02, chemical bond
