The following video podcasts are science concepts based on Science Curriculum with a focus on the Chemistry unit on the Periodic Table, Naming Chemicals and Writing Formulas, Balancing Equations and Identifying Different Types of Reactions. These lessons are to be downloaded to your computer for assistance in homework or reviewing older material just prior to your final examination in the course. Mr. Papadimitriou is a high school Science/Math/Credit Recovery teacher in Scarborough, Ontario, Canada. I am presently looking for any sponsorship or financial aid for my high school as we are steering towards being designated an M.S.T School (Math/Science/Technology). Any addition assistance, comments and donations, contact Mr. P at [email protected]
