Science 9:  We began with a short review, them we learned how to name and write formulas for binary ionic compounds, like Sodium Fluoride.  We did 10 practice problems, then set up Lab 5A.  In the second half we completed Lab 5A to learn about the chemical change that occurs when a candles is burned.  You will be given time to complete Lab 5A on Friday.  Make sure that pg 208 from Tuesday is complete.
