Goodbye Nuclear, Hello Organics

We went over guidelines designed to help students maximize their lab report grades. Download this link.

Tuesday is a test on Nuclear Chemistry.

In lab classes today, students got a start on a homework assignment. Trends in Alkane Boiling Points has students graphing data and then answering questions pertaining to the information.

The lecture notes for the Organic Chemistry unit can be found here.

Nuclear End of Unit

We watched a video about Marie & Pierre Curie's groundbreaking work in the early 20th century. This link takes you to the video series it was a part of. The section on the Curies is in video #2 the second half.

The next unit is Organic Chemistry. This is the packet for notes that I passed out in class.

Radioactive Decay simulation

This is the data that is needed for the Radioactive Decay Simulation lab. If you are in my Day 2 lab this is what you will graph for the lab. Be sure to align the paper in landscape format and put the number of trials on the horizontal independent axis and the number of blocks/chips on the vertical/dependent axis. All other groups should add your data to these totals to graph correctly.

More Nuclear

I have edited Mark Rosengarten's notes down and added some problems to make a 10 page review packet for the nuclear unit. Click here to get the packet.

Nuclear Chemistry

Tests have been graded and handed back. We went over the test, question by question, in class.

We began the nuclear unit. The link for the notes for the Nuclear unit is here.

We currently have three labs scheduled for this unit:
Isotopic Pennies
Decay chain of Uranium
Half Lives

We will have a quiz on material from the nuclear unit on Wednesday.

First Unit Test Coming

Our first test will be this Thursday, March 30. The test will be on all the material that we have covered since I started on March 6th. This includes energy diagrams, equilibrium and vapor pressures; and includes information on Tables H & I. Links to notes and appropriate resources can be found on the blog entries for the past few weeks.

We started watching the video Atom: Clash of the Titans, in preparation for the upcoming unit on the nucleus. This can be viewed at home by following this link.

The link for the notes for the next unit, Nuclear, is here.

First Unit Finished

All classes have finished the first unit. Click here for the notes on the Phase Changes.

First and fourth block classes will have a quiz on Monday.

There will be a unit test for all classes on Thursday.

We talked in class about how air pressure is exerted all around us. We saw a short video where they filled a train tank car with steam and then sealed it and the container collapsed. I discussed a small scale demo of this processing a soda can, and I offered students 3 points extra credit of Thursdays test if they do the experiment at home. To do this at home a person needs to put a small amount of water into an aluminum can and heat the water to boiling. The can should be held with tongs or a couple of forks (turned to hold the can). After the water boils you should see the condensation of the steam at the top. Wait two seconds and then invert the can into a large unbreakable container of cool/cold water. The can should collapse under the pressure. Bring the can in and get the 3 points. This is how it should look.

Similar experiments can be dine on other scales, like a 55 gallon steel drum.
