Homework,
Handouts, 
As a teacher, I like to think that my presentations are so good that you learn the topic right there in the classroom. However, this isn't usually true. Most likely you gain an awareness of the topic and, hopefully, I get you interested in the topic. I also try to reinforce skills that will accelerate your learning, such as viewing chemistry as building blocks, force & energy, and mathematics. I will also remind you to use learning skills and watch out for the barriers to learning.


The real learning comes from going over the material by yourself and making the knowledge your own. In other words, you need to rework it in a way that it becomes your knowledge, not mine. For example, I go over the early uses of chemistry in class. You may start with what I've covered but then do some of your own research to find out more. Another example could be my talk about the development of the Periodic Table of the Elements. You may then go to the textbook and/or Wikipedia and learn their view of the development of the Periodic Table. You will also find out there are different types of Periodic Tables. This reinforces what I presented but also gives you more depth and makes it your knowledge. You can learn more about it than what I know. I'm just a starting point for what you can learn.

The first homework assignment replaces a presentation I usually do in class. Class time isn't enough to cover everything you need to cover to go on to CHM152. I have Web pages that do a good job in covering this presentation. This topic is broken down into six Web tutorials. The links to them are on my CHM107 home page. Scroll down and look for the "Chemistry's Big Picture: It's all about building blocks" These are tutorials 4, 5, 6, 7, 8, & 9. Go over them. The homework to turn in are the quizzes that go with tutorial 8 and tutorial 9. You can copy and paste the quiz questions from the Web page to your email and email them to me at costello@chemistryland.com. Or you can write or type your answers and give hand it in on paper. I don't have a due date for this assignment at this time.

Posters are commonly used at chemistry conferences to communitate the results of projects or research. It allows many people to present their material at the same time in an efficient amount of space. Learning how to do an effective poster is a valuable skill for many purposes. The poster project is due April 27th. The topic is anything related to chemistry. Tips on designing a poster is found at this URL: http://www.mc.maricopa.edu/~costello/posters/index.html An easel or table will be provided for your poster.
