We used the PhET simulation from 2-24-11 to show how an acid diluted 10-fold will see its pH go “up” one whole number (Ex. from pH = 2 to pH = 3). The same will happen with a base and its pH will move towards pH7 as well. Students completed a chart in their notebooks to summarize important terms in acid-base dissociation. Smartboard notes 3-1-11
Twenty five questions (PSSA Practice #3) that deal with topics that will be on the PSSA exam. How are you doing? What strategies are you learning? How will you prepare for the exams?
If time, students take a look at the pH activities below. Pretty cool! Click on image to access site and then choose the green RUN NOW button. Your assignment is to comment on one of these simulations. Include 1) something you already knew 2) something you learned, and 3) a question that you have. Mention if you were using the “pH Scale” or the “Acid-Base” activity.
Lab today to determine the actual pH of some common household substances. Smartboard Notes 2-15-11. How did your results compare with this chart?
Students assigned common household solutions to three categories – acids, bases, and neutral solutions. Lab notebooks were turned in with the lab activity completed up to and including the “Stop and Think” questions on p.224. Acid and Base song!
