Physics 30 - Lab 4.2 Video for Supplemental Worksheet

For students who were away during the last two days, we watched a video that serves as an extension to Lab 4.2.  You will need to watch the video to answer the questions on the worksheet.  Below are the three parts to the video.  Use the information provided in the video to answer the questions.

Physical Science 20 - Lab P5 Link

Go to the following website http://www.surendranath.org/Apps.html.

Scroll down the page until you reach the Wave Motion Menu.

1. For Part 1 - select transverse waves
2. For Part 2 - select longitudinal waves
3. For Part 3 - select superposition of waves
4. For Part 4 - select reflection and transmission

The handout is due tomorrow - no formal lab report.  Whatever is not completed in class needs to be completed on your own time.  

Science 90 - Unit 3 Universe Unit Review

Here is a series of questions that students can look at to help study for the exam this week on Unit 3 - Exploring our Universe.

Physics 30 - Dec 7

Today in class we then went on to learn about an extension to lab 4.2, the existence of something called dark matter.   We learned in the lab that more mass causes more speed for the centripetal motion.  This applies for simple motion that we see on Earth, like a stopper spinning around on a string, as well as the motion of stars in galaxies. 

We learned about a currently anomaly in physics.  This was the fact that stars in a galaxy are moving much faster than they should be.  The mass that consists within the galaxy that we can see is not enough to make the stars move so fast.  This is the basis for the search for dark matter. 

We watch a video today to explore these ideas a little further and to learn more about dark matter research.  Students answered a worksheet that went along with the video.  The worksheet is found here.  It is called Lab 4.2 Supplemental Worksheets.  The video is linked in 3 parts in the Course Video Youtube playlist.  It is called the Mystery of Dark Matter.  If you were absent today, please watch the video there.

Physics 30 - June 8 & 9

Today we started Unit 6 on Nuclear physics.  Students learned about atomic models and particularly the make up of the nucleus.  We then learned about the strong nuclear force that binds the nucleus together as well as the mass defect and binding energy.  We calculated the mass defect and binding energy for an isotope.  Students were then given sometime to work on Assignment 6.1.  On Monday we will review radioactivity and learn about radioactive decay equations.
