Mr. Burk's Top 5 Places to Study in Atlanta

One more great suggestion from Study Hacks is how Adventure Studying is a great way to prepare to study.

What is adventure studying? It's finding a cool, beautiful and quiet place for you to go away and study (and adventure doesn't involve Starbucks).

Here are my top 5 suggestions in the Atlanta Area:

1. The High Museum of Art—admission is a bit pricy ($15), but the cafe across the courtyard is free, rarely crowded and a great place to sit and admire the physics of the alexander calder mobile in the front (ever wonder how it stays balanced?)

2. Chuck E Cheese. You know you loved it 5 years ago. Why not go there, work for 45 minutes and then play some skee ball to put your physics knowledge to the test? If you go, bring headphones and find a quiet corner away from all the dancing robots.

3. A local college—Agnes Scott, Morehouse, Spelman, Emory, Georgia Tech—all of these places have beautiful campuses and libraries. It can be great fun to go to a college library for the afternoon.

4. The Carter Center--Recently completely renovated, you can visit a full scale model of the Oval Office (and that's a place where you really need to understand physics--check out Physics for Future Preisdents--a real course at UC Berkeley).

5. Outside—yes, it's supposed to be a bit rainy and cold this weekend, but it it would be great bundle up, to throw some FARMIPS and and some blank paper in your backpack, and go hike to some quiet, isolated place and solve physics problems under a tree.

You need to watch this!!

Ok, if you thought today had some insane projectile motion, you need to check out this video.

Just a side note: turn up the volume on your computer and know that this is 100% genuine and was created by people somewhere and it's going into the Smithsonian soon!

Class last Thursday

In advance...I do not know how to get the pictures up on the post...I am sorry. If you want the pictures for that class txt me and I will give them to you.


Now then: Our began with simple note taking on energy and pie charts about energy. We learned that there are 3 kinds of energy that we use. #1 is kinetic energy. #2 is Eint, and #3 is U(insert letter here). All thease types of energy happen at different times when a ball is dropped. We then took our energy packets and each did a problem on a whiteboard for about 30 mins. After that, we presented our problems while explaining it to the class. (I will post more on this tomorrow with pictures)

how to create an online calendar for the upcoming week

I've created a google spreadsheet to help you plan out your success week to help you demonstrate your best understanding on the exam. To use it, go here

Study Plan for Finals Week

The spreadsheet is read-only, so you'll need to make a copy.

To do that, click on "File > Make a copy" as shown in the image below.

If you'd like me to see your study plan, simply share it with me via google docs (this is completely optional).

5 Mistakes to avoid during finals

Here is more great advice from study hacks:

5 mistakes to avoid during finals.

We'll talk about this a bit tomorrow, but here they are briefly

• Mistake #1: Not Having a Clear Schedule
  
  You should set up a plan for using the time you have to maximum benefit—giving yourself time to rest, and reflect so you achieve maximum understanding.
  
  
• Mistake #2: Not Purging Your Obligations
  
  Avoid letting the little things in your life keep you from having the
  time you need to seriously prepare for exams.
  
  
• Mistake #3: “Studying”
  
  Focus on specific action. Solve problems.
  
  
• Mistake #4: Social Working
  
  While it can be helpful to work with others, often, working in a noisy space with friends can be very unproductive.
  
  
• Mistake #5: Calculating Your Final Grade
  
  I'll let Cal speak for himself:
  
  

  
  Don’t do this! No good can possibly come from such a superficial focus on the numbers. It will add stress. This, in turn, will make it harder for you to execute a reasonable, specific, and efficient study plan. Also, it’s just plain crass. You don’t want to be that person…
  

  
  

Friday December 4, 2009

Today, we reviewed the packet that we were supposed to do on Wednesday. We started with Problem 6 which was Paxton and Sana's. This problem was way more complex than it looked. It is pictured in the first image, the orange one. The objects in the system are the spring the Earth and the object.. The first pie chart is entirely Ue. The second pie chart is half Ug, half K. The last pie chart is all Ug.

Problem 7, the second picture, the purple one, involved the clay and the Earth. The first chart is entirely Ug. The second is half of Ug and half K. The third is Eint, because it hit the ground.

The final problem involved the truck, the Earth, the road, and the gasoline (which is technically part of the truck). The first part is half K half Uchemical, from the gasoline. The second chart is half K, one quarter Eint, one quarter U chem. The final chart is half K, one third Eint, and one eighth Uchem.

Class on Tuesday December 1

The first thing that we did in class was take a reassessment on chapter 3. Then, we turned that in and continued our discussion of how different things hurt us and why. We concluded that objects can hurt us for many different reasons, including mass, velocity, displacement, and heat. We also guessed that how objects hurt us is related to energy. Then we derived an equation with displacement and acceleration in terms of final velocity and initial velocity. Then we took a break, and when we got back, Mr. Burk gave us propsicles. After the break we started on a lab. We set up a cart and a spring on a ramp, and launched the cart on the ramp with different inclines. This is what the set up looked like.

We measured many different aspects of the cart's motion as we changed theta, the angle of elevation of the ramp. Specifically, we measured the cart's maximum velocity and we measured the hight that the car traveled. We found that the height remains the same regardless of the angle. Finally we started working on the energy work packet. We discussed the types of energy that we know so far: kinetic and potential, but we can't call it potential because we don't understand what that means. That's all we did. Homework is test corrections, and the next blogger is Dylan.
