All Courses - New Place for Blog - Updated 9/15/2014

In an effort to put my blog in a more organized fashion, I am trying to split up the classes I'm teaching into separate blogs. You'll find the course links on the page on my blog titled, "Links to Courses".

I have just started moving the posts, as of 5:45 PM EDT, 9/15/2014. I expect to finish moving them all by this evening. Please be patient!

If I have done something that prevents you from seeing the new blog, please email me to let me know (colszewski@ctemc.org).

Thanks!

Bioengineering - Week of 9/8/2014

Ladies and Gentlemen,

   Here is the description and requirements for the write-up of the paper tower investigation activity you all did on Tuesday. Basically, I want you to describe the three alternate approaches to building the paper tower, how you tested them, and what you found out. I believe that you should also include pictures and sketches to best describe the approaches you were investigating. Essentially, these sketches are part of your design notebook.

   This assignment will be due Monday 9/15.

Sophomore Physics - Week of 6/16/2014 - The End of Physics

Ladies and Gentlemen,

   Well, it looks like we're really coming down to the end. We have two full classes left, and A day will get about an hour on Wednesday morning, just before their first exam. There is just one topic that we need to cover (series and parallel circuits), and I don't think it will be that hard.

             Answers here
             I expect that these will take you about 30 to 45 minutes, in total
             You should also be studying for the final.

Exam Comments and Resources:
   The exam will be held on Thursday morning, and it will be the second exam that day. Following the exam will be the school picnic, and so you will have that to look forward to.
   The exam will be on the following topics - see the topic list sent with the review materials from Mr Pinkus:
  1) Energy, mechanical energy, and conservation of energy / mechanical energy
  2) Waves: terminology,  types of waves, standing waves, wave phenomena
  3) Sound waves, wave media, type of wave, wave phenomena
  4) Light waves, color, color vision, reflection, refraction, travel
  5) Mirrors and lenses: reflection, focal lengths, ray diagrams, mirror and lens equations, real/virtual images, magnification
  6) Static electricity: charge, Coulomb's law, types of charging, electric fields, electric potential difference.
  7) Current electricity: current, voltage drop, resistance, Ohm's law, power, kWh, series and parallel circuits

   Here are some of my viewgraphs:
  Energy, mechanical energy, and conservation of energy / mechanical energy
  Waves and sound waves
  Light waves and mirrors
  Lenses
  Static electricity
  Current electricity

  I will also be available in the Physics room (113) during lunch on Monday and Wednesday (both halves), and during 2nd half on Tuesday.

To try to take your mind off of physics, here are a couple pictures of rainbows I took recently in Point Pleasant. Note the double rainbow in one picture.

Oops! There's physics even in the rainbows!
