Getting Started

Both Physics sections took a look at the scope of the field of physics, in terms of what types of topics fall under that umbrella. We examined areas of both classical and modern physics and how examples of these areas could be found in daily life. Time was taken to review the scientific method and how it applies to the growth of scientific knowledge over time and how the use of models assists in the formation of hypotheses and controlled experiments. Tomorrow, we take a look at the metric system and how measurements are made and reported to maximize information about precision.

Honors Physics started the class off by going over yesterday's lab on the weights of pennies. Both pre- and post-1982 pennies had very clean direct linear relationships to weight, but the slopes of the lines were different. At different points in history, the composition of pennies has changed, giving pennies different weights. The lab itself acted as an introduction to the Vernier system, which we will use extensively in this year's lab investigations. After the lab wrap-up, attention was turned to the introductory housekeeping tasks of reviewing course expectations and getting textbooks assigned. Tomorrow, we start in on Chapter 1!

Physical Science worked through the first section of Chapter 1 material in class today. The first chapter of any science textbook is designed to orient students as to the scope of the course topics and introduce basic tools and techniques necessary to succeed in the class. We looked at the different branches of science and specific areas of study that fall into each branch, contrasted pure and applied science, as well as laws and theories, and discussed the use of models in scientific studies. Tomorrow, we'll be working on a lab investigation that will allow folks to explore the use of the Vernier probeware system, which will be the backbone of this year's lab program.
