World History Workday...

On Wednesday, March 16th, there will be an IN-CLASS WORKDAY for our project entitled The Explorer and His Ship. This project is due Friday, March 18th, by the end of the class period. Be sure to bring in materials each day to work on after I get done going over the lesson. I look forward to seeing your creativity!

Review First Half of Physics 16B...

We began Friday with a review of the Zeroth and First Law of Thermodynamics and the work that heat is capable of producing. Section 16B introduces the Second and Third Law of Thermodynamics. The Second Law establishes the fact that heat flows from a "higher concentration" or hotter object to a cooler object or "lower concentration. This principle is the behind the functions of internal and external combustion engines. This video does a great job of explaining the use of this Second Law and how an engine works.

Remember to study the names of the men that were responsible for the study and development of the engine.

This section of Physics also used the Carnot Cycle to show the idea of what an ideal machine would look like--meaning a machine that has 100% efficiency. You will have to remember the four steps of this cycle for the test as they are described in the video below.

On Monday we will be finishing this section and then continue with 16C on  "Entropy and the Heat Death of the Universe."

Can You Find...

Only one more week until Spring Break! Are you as excited about the week off of school as I am? Well, in honor of this wonderful break from school here is a new picture to find. When you do find it, tuck that little piece of information away for the next quiz and an extra five points!!

Products of Our Greek/Roman Craft Project...

I'm sorry that I haven't posted these pictures sooner. Everyone did a fantastic job the Greek/Roman Craft project. These crafts ranged from a shield...

 ...a Roman house...

 A Greek Lier...

 ...to a Roman structure.

There was even a replica of Mount Olympus and another Roman structure complete with ivy! Way to go, Everyone! I am looking forward to this next one: The Explorer and His Ship.

Be sure to bring materials to work with tomorrow. There will be time to get some things started with this new project after the test is taken!

Physics 16A Recap...

If you are interested in refreshing or reviewing the information on thermodynamics that we have started studying in chapter 16, here are the videos that we have watched in class and discussed at length. If you have any questions please be sure to ask!!

To understand more about what the Zeroth Law of Thermodynamics is (and one I had never even heard about until teaching this book) sets the parameters for temperature in relation to a gas. Now gases seek thermal equilibrium and according to this law if Gas A is in thermal equilibrium with Gas B and Gas B is in equilibrium with Gas C; then Gas A and Gas C are also at thermal equilibrium.  Here is the first part animation of this concept.

For the 1st Law of Thermodynamics (the "conservation of energy" law) describes the fact that thermal energy is neither created or destroyed. It is simply converted into another form of energy. Usually when Heat (Q) is added to a system, there is a change in Mechanical Energy (delta U) plus Work (W) that is done.  Mr. Anderson explains this law along with other thermodynamic processes (in relation to gas using our gas equation PV=nRT) and how they can be charted on a graph when 1) pressure is constant, 2) when volume is constant, 3) when temperature is constant, and 4) when there is no change at all or an adiabatic process (NOT bolded in your book but is still a thermodynamic process even though nothing changes). These are all graphed differently on a P-V diagram. It will be imperative that you remember the names of the processes and how they are graphed.

And last but not least this video by Doc Physics will put together both laws and how they relate to work and mass-less piston. The key to this is understanding what the negative signs for both heat and work indicate in the equation.

Again if you have any questions be sure to let me know. Hope this will help in your review for the quiz over 16A tomorrow and the test next Friday.

Can You Find...

Ready for a new bonus? If you can find the above picture hidden somewhere on this blog and then write down where you find it on the next quiz, you can earn yourself +5 points! Ready? Set? Go!

11th and 12th Project...

On Friday, March 4th, explorers will be chosen for our next project for part of the month of March. Be sure to check out the requirements over to the right hand side under PROJECT: The Explorer and His Ship. All information including due dates are found on that page.

As for the creativity of the project, I want each of the students to think outside the box. In fact, their goal should be to impress the teacher. We're studying about the rise of England, France, Spain, and Portugal this chapter and the impact they had exploration. Wow me!

Be sure to check out other projects done by the 9th and 10th Grade back in September. Simply click HERE to go to the post with pictures from their ships. If I can help in any other way be sure to ask.

Now get out there and get those creative juices flowing!!
