HON CHEMISTRY – Here’s a pic of some “high density” koi that I saw in Hawaii (at the Dole Pineapple Plantation, of all places!). Great applicaitons of density today! Remember, in chemistry we use math as a tool, therefore we might work problems a little differently in chemistry than you do in your math class.

When working these problems, don’t forget to follow the problem solving steps we discussed today:

**Analyze**– write down what you’re given and what you’re looking for**Plan**– write a formula where you isolate the unknown on one side by itself**Compute**– plug in your data, numbers and units; then cancel the units, and if they cancel correctly, go on to the calculator. Be sure and give your answer what the correct units.**Evaluate**– does your answer make sense, have you used the correct units, do you have the correct sig figs?

I had a difficult time understanding uncertainty but I was able to at the end of the week and finish my fundamental science skills.
