Physics 1-25-16 Torque & Rotational Equilibrium

PHYSICS: Welcome to the first day of a brand new chapter in physics – one of the last we’ll do on mechanics!! Here’s the lecture on torque – a different kind of motion involved. So how’s the balance in your life right now?

Chemistry 1-26-16 Spectroscopy Lab

CHEMISTRY: How’d you like playing with light? Kind of pretty, huh? Check with me in class – we may end up doing the outside part on Thursday instead of Wednesday as it’s a bit chilly outside!!! If so, the lab packet will still be due at the end of the period on Thursday so you can finish those last couple of questions.

Are you clear on how to turn in the lab report? Observations from the diffraction grating today will be in two parts: 1) the written observation – answers to those four questions for BOTH types of light on notebook paper, and 2) your drawings of both kinds of light on card stock or heavy white paper, and then both drawings mounted together on one sheet of construction paper. Be sure to label everything.

Observations from Part 2 with the spectroscope will be answered on the actual lab sheets/packet. Be sure and read ahead so that you can double check to make sure you answered every single observation and question. The entire packet will be due on Thursday!!
