  Nothing for now...

We took the district common assessment exam today.  Tomorrow we will have a party and celebrate the end of the semester before finals begin.

1.  We went over the rest of the practice exam today.

homework: study for final.  we will take the common assessment exam on monday

1.  We spent the entire period going over the first half of the practice exam.

2.  Mr. Kleiner was disappointed that about 70% of the students had not even completed the practice exam on their own.  Students only put effort into learning if they get a reward for it such as points.  Otherwise they don’t do it and this is a shame.

homework: complete the practice exam so we can finish the rest of it tomorrow.

We spent the entire period going over the heat practice exam

homework: complete the practice exam.  We will go over the answers tomorrow

We spent the period going over the review packet answers and going over student questions.  Students that did not want to participate in the review were able to read magazines in the back of the room.

homework: finish the heat practice exam

1.  We had a discussion about what we learned from the Rube Goldberg project.  Popular lessons learned from all classes were that engineering projects require lots of time and planning.  Also, students learned that it is not easy to give an entertaining and engaging presentation to a group of people.  You need to speak loudly, you need to have good visuals, you need to know what you are talking about.

2.  Students began working on a review packet for the final

homework: finish the review packet

1.  We saw a video of an ideal black body radiation emitter.  A black carbon block was heated up to a temperature of 2000 degrees celsius and the carbon was so hot that it gave off light and glowed.

2.  We discussed how the common incandescent light bulb works the same way.  Tungsten metal inside the light bulb is heated up so much that it gives off light.

3.  We had a discussion on Google and Mr. Kleiner took student questions about how Google worked.

1.  We had a class discussion in which we discussed how to build a thermos.  We learned that insulation is required (vacuum) and silvering is required (to stop radiation)

2.  We discussed how the space shuttle must rely on radiation to get rid of its excess heat.

3.  We watched some videos on a thermos and also a video on cryogenically frozen materials.

homework: turn in your global warming project and your specific heat lab tomorrow

1.  We did a lab today.  The purpose of the lab was to determine the specific heat of an unknown metal.

homework: the lab is due on Friday

1.  We spent the first ten minutes of class covering student questions and comments about Mr. Kleiner’s decision to leave at the end of the semester.

2.  We went over the problems from the chapter 22 homework from last week.  We discussed in particular:

a.  why metal objects feel colder than other objects in a room (conduction)

b.  why the retina appears black

c.  what is terrestrial radiation

homework: keep working on your global warming projects
