Physical Science 20 - May 10

Today in class we went over Part C to Homework P5.  We then started looking at an application of refraction.  We learned some terminology involved with studying lenses and optics.  This didn't take too long.  After which, we watched a video on optics.  There was no assignment today.  The notes were on slides 64-72.  Tomorrow we will look at finding images in lenses graphically.

Today students handed in Assignment P2.  Afterwards we continued to learn about critical angle and total internal reflection.  We reviewed what we had learned yesterday and then took some more notes on total internal reflection and some applications of this knowledge.   These notes are on slides 60-62.  Students then had some time to work on Part C of Homework P5. We will go over this tomorrow.

Today in class we went over Homework P5 Part B.  Afterwards I let students work on Assignment P2 for about 20 minutes and then we started to learn about critical angle and total internal reflection.  I showed the students some demonstrations on the topic and then we took some notes on it and went through one example.  The notes were on slides 57-59.  We didn't get to an assignment today with this but students need to make sure to hand in Assignment P2 tomorrow.  Tomorrow we will finish up learning about critical angle and total internal reflection and then get a chance to work on an assignment in it.

Today in class students handed in their lab reports for Lab P3.  After that, we took some notes on the laws of refraction and then learned in detail Snell's Law.  This is the law that governs the angles of incidence and refraction.  We also did an example that showcased Snell's Law.  The notes today were on slides 53-55.  Students were assigned Homework P5 - Part B to have done for Monday.  Have a great weekend everyone.

May the Fourth be with you all!!  Students have had a couple of days to work on their formal lab reports for Lab P3.  Yesterday we had our quiz on Homework P1, P2 and P4.  So we didn't have much time to work on the lab report.  Today I wanted to give a little lesson on graphing.  After the lesson today, students then had time to work on the report.  This is due tomorrow.  We will continue tomorrow with our study of refraction.

Today in class we studied the relationship between the incident angle and the refracted angle.  Students did this with Lab P3.  We will get time tomorrow to analyze the data from this lab.  If students were absent today, there is some sample data called Lab P3 sample data that you can use.  It is in the Physics folder of the Physical Science 20 course notes link on the right hand side of this webpage.

Physical Science 20 - May 1

Hello everyone.  Today we went over Homework P4 and then started into our next property of light - the property of refraction.  This is how light behaves when it passes through substances.  When light moves from one substance to another, it will change paths or bend.  We learned some new terminology today as well as why this bending happens.  Notes today we from slides 43-51.  Students then had some time to work on Part A from Homework 3.5.  We will take this up tomorrow.
