10/21 Chemistry update and homework due 10/28
Hi folks,
Today we took a look at the five phases of matter, phase change and the relationship between heat, temperature and phase change.
Homework this week is to:
Answer the following questions
Do the enclosed worksheet .pdf.
Create a temperature vs. time graph of your data from the lab this week. Please put both the oil and the water on the same graph. Feel free to have your temperature axis go from 90℉ to 130℉ (instead of 0 - 130)
1. What are the five phases of matter?
2. Describe what happens, molecularly, as a solid increases in temperature and changes phases. Be sure to include a description of the bonds and how they change over the process. Also, what would temperature be doing over time as this substance changed temperature.
3. List the states of matter from least amount of kinetic energy to greatest amount of kinetic energy.

10/14 Chemistry update and homework due 10/21
Hi folks,
Today we began a new unit on heat and temperature. To get the ball rolling, we spent time talking about what temperature is, and the three ways to measure it. We also did a lab where we heated water from solid form to liquid form and recorded the temperature every 30 seconds. Due to timing and power issues the data didn't turn out as "clean" as I would have liked so I've created a data table for this week's lab and included it below.
For homework this week:
Complete the enclosed .pdf.
Use the included data table to create a graph that relates to the lab we did in class. Label the graph with the "notes" I've included in the table.

10/7 Chemistry update and homework due 10/14
Hi folks,
We did a bit more work with the basics of energy today. Specifically, taking a look at conservation of energy and energy efficiency. We did a lab to evaluate the energy efficiency of a pendulum.
The book really doesn't go into enough detail as far as the basics of energy goes, so I'm including an eBook version of my Bite-Size Physics: Energy book for more background.
Homework this week is to:
1. Read the enclosed eBook up to the Vibrations chapter.
2. Do the "Did you Get it" questions at the end of the Energy chapter.
3. Do the "Did you Get it" and the "A Little Math" questions at the end of the Kinetic and Potential Energy chapter.
4. Finish the lab from class. You should have the potential energy from each swing, the potential energy lost after each swing, the energy efficiency of each swing and, lastly, an overall energy efficiency average.
