1st Year Podcasts

Welcome to our first-year podcast series.

This series of tutorials has been developed to support students in our Year 1 Chemistry courses at McMaster. Because they are intended in part as review, the series is also at a level which will support senior level high school students.

The podcasts currently available are on topics related to acid-base chemistry. We invite you to view these tutorials, which vary from about 2-7 minutes in length, depending on the topic.

If you have comments/feedback on what you see, or suggestions for future topics, please send a message to: Pippa Lock (Year 1 Coordinator),
