Chemical vs. Physical Change Lab

Posted by: Scott on: October 6, 2008

I created this lab last night and we did it today.  Overall it went fairly well. physical-chemical-change-lab I began the lab by lighting a strip of magnesium to demonstrate a chemical change.  All that is left after that very bright flare is white powder.  They really liked that demonstration.  Then on to the lab. The [...]

Demonstrating a Chemical vs. Physical Change

Posted by: Scott on: August 24, 2008

This is a standard demo, one I did with my 8th grade Physical Science class and it stuck with them.  It uses sugar to show the difference between a physical change and a chemical change.  The first step is to dissolve sugar in water and then evaporating the water over a low flame.  I usually [...]


About this Blog

Hi, I'm Scott. I teach in a charter school in the city of Philadelphia. I started this blog to help me keep track of the things I want to do in my classroom and it kind of got away from me. I still use most of the lessons and activities you see here, so I know they work. Feel free to email me with questions, I'm happy to help.

It's 2011/2012 which means my courses are different once again. When I first started, I taught two courses, Physics and Conceptual Physics (which is physics-lite). Year 6 at this school has seen a maturing of our science program, we are offering many more science electives. There is no more Conceptual Physics (oh yeah!!). I've got two sections of Physics, one of Calculus, and this year two sections of my STEM elective - now called Robotics & Engineering.

As always, I'll be adding activities, ideas and insights as I come up with them. I also update old posts with new information as I redo the activities. Many of these activities are good for summer camp and just experimenting at home, so dig in and please feel free to add your own ideas.

Most importantly, comment and/or contact me. I'm here all the time since, like you, I'm always working on lesson plans, labs, and other activities to engage my students. I am never too proud to borrow a good idea that works. Enjoy.

Yeah sure, lots from America, but look who else is here…

If you are badly in need of more email or for some reason jonesing for a physics fix, enter your email address so I can bother you with my newest rant on science.
