everyday observations that we ll answer this semester Why does rain fall as drops instead of as cubes or cylinders How can some animals walk on ceilings Why does salt help to melt snow from roads Why is the sky blue Why can some insects walk on water Why is ozone depletion bad Sheets Page 2 Lecture 1 How do we know what we know You know that table salt contains Na and Cl ions earth s atmosphere is

lectures recitations invest the time 10 hours week outside of class studying homework read text before after lecture bring lecture notes incomplete notes available on website notes are only a guide courses chem psu edu chem110 faculty sheets do problems in text do supplemental problems work together work alone homework problems give good idea of what is expected do em understand em homework done before recitation Please don t fall behind Seek out help when you need it don t wait until the day before the exam Sheets Page 7 Lecture 1 How to succeed in Chem 110 part 2 1 Suggestions from past Chem 110 students Getting a study group early helps a lot Even if its just people who you are comfortable asking questions with in class it makes a large difference Also you were right about studying and starting early as opposed to cramming I would suggest to other students to keep up with the material and read the sections in the text book ahead of time I felt that it was very useful to know what you would be talking about ahead of time so that I could concentrate on the areas I did not quite understand Please attend all lectures If you think you have a strong grasp on the subject and then not attend for two weeks before the final it will show in that subject area I found that doing practice problems along with the lecture definitely helped because I would sometimes find myself a little lost in the words and explanation of the topics but then the example problems would help to put it all in prospective For future chem 110 students I highly recommend reading the book I read the book the night after every lecture which reinforced what was taught and helped me understand what the book was saying Sometimes reading the book before lecture was a little confusing as I didn t have a preview of what we were learning I would also recommend doing all of the homework even if you have enough homework points The homework provided perfect examples of quiz and test questions Sheets Page 8 Lecture 1 How to succeed in Chem 110 part 2 2 i would say that the best thing to do to succeed in chem 110 is to read the text it helps so much if you don t you will probably feel very lost in the lectures and it will make the homework ten times more difficult and don t leave the homework until the last minute make sure you let yourself take your time with it and make sure you understand it because that s what the quizzes and the exams will be like I would suggest doing the homework shortly after the lecture It made it easier on me when I did the homework in conjunction with the lecture rather than waiting until say the weekend to do it I think practice is the best way you can succeed in Chem 110 You need to do the homework problems and apply the concepts you learn to keep them in fresh in your mind By trying to solve so many different problems you will be able to apply everything you will learn to solve any problem that deals with those concepts ATTEND LECTURE You can t do it by yourself Also start studying early because there is too much material on the exams to cram in the night before Also don t only rely on the practice exams as they change from year to year and stress different things each year Work on practice exams but also review the lecture notes and homeworks The only suggestions I have for future students is to actually read the sections in the book assigned for each week and to put real effort into the homework problems Just copying down the answers from the back of the book or the solution manual will not help them out on the exams Sheets Page 9 Lecture 1 How to succeed in Chem 110 part 2 3 In order to succeed in CHEM 110 all you have to do is read the book do the problems and go to lecture And oh yeah don t ever get satisfied with a grade That to me is extremely key I got very high grades on my last two exams in class so I think I relaxed a little too much when it came down to the final exam I still did well in the class probably a B but I certainly could have done better probably could have kept that A Be happy when you get good grades but don t ever get too comfortable You re rarely ever completely locked into a grade I know that most of you guys heard that Chem 110 sucks I have to admit that was the first thing I heart about Chem 110 There is nothing difficult in this class as long as you keep doing your homework and be present in all Dr Sheets s Lectures After all they are so much fun Do not just study the day before the exam you will regret it I had no previous chemistry background but I still managed to get an …
