July 21, 2003 Task You are going to work with your group (3 to 4 students) to do a science experimental project. The project can be something that you observe in your daily life and you are interested to find out why it happens, or you want to know how things work. (Date of completion will be discussed on this Friday, July 25) Discussion Discuss with your group members:  To choose a project that your group is interested and is workable in the lab. or at home;  To elect a group leader;  To divide the workload among members;  To plan the experiment;  To set up the time line of the project. One Page Proposal Once your group has decided on the project, write a one-page proposal that includes:  The title of the project  A very brief description of your thoughts about the project and of the work that

your intend to carry out  A full list of apparatus and materials needed (use what we have in the lab. or you can get easily)  Results that you expected  A time line of the project (Best to be handed before Aug 1, Friday through email to [email protected]) Project Diary Keep a diary of your project. You should not trust yourself to remember facts and details. Record everything in your diary and use it as an information store for writing your report. You can even write personal comments about how your project is going and what your progress is like. References: 5.

In this website, you can travel through several virtual exhibits to learn about technologies based on electricity and magnetism. Each exhibit includes explanations of how things work, historical and biographical information, and links to other resources. Exhibits cover “Women and Technology”, “Thomas A. Edison”, and “microwaves”, but you'll want to start with “Socket to Me, a brief history of electricity”. http://www.ieee-virtual-museum.org/index.php
