Physics 11 – Today we continued with our investigation into mirrors.  Students found the focal length of a mirror by projecting an image from a distant object.  Next they were asked to find the image distance for a given object distance, using three different methods: direct measurement, calculation using the focal length, and doing a scaled ray diagram.

As I noted from last day in physics, I hoped that students could use a cooperative learning environment to successfully solve mirror problems.  It turned out that the substitute felt that kids should work quietly and independently.  Uh huh.

Day 155 – Fundamental Particles

Science 8 – Students followed a WebQuest to learn about Quarks and Leptons. The class was really engaged, even though they had to share one computer for every three kids. When we reviewed the activity and I randomly called on students, they were all able to give an answer and seem comfortable with what they were saying.

Here is a link to the document I gave them to follow: fundamental particles

Day 154 – Mirror Equation

Physics 11 – Today was a very short day for me, as I had to go to the board offices for some training on our new SIS.  It was a good test for the students though: I left a package on doing calculations for mirrors. The idea was to use the readings, worked examples, and student crowd sourcing to figure out how to do these types of questions. Once a student gets a correct answer to a question and feels comfortable with the solution, they put their name on the whiteboard and volunteer as a helper for that question.

Day 153 – A View from Here

Science 9 – Students were asked to create a small project.  Each group was given an object to research. They had to find a bit of information about the object, and then describe what the Earth would look like if a person were on the object looking at us right now. So if a person was in the Andromeda Galaxy which is 4 million light years away, they would see the Earth as it was 4 million years ago. It was a great activity to learn about different types of objects in space and learn about distances in the universe.  This activity was taken from the Perimeter Institutes teacher resources.

Day 151 – Playland pt2

Science 8 – My grade 8 students went to playland today. It was another warm and sunny day and an overall good experience. I must admit that I really question the purpose behind this field trip. I’m not sure if it will happen in subsequent years for grade 8’s with the new curriculum.
