Science for All

Across human history, every culture has attempted to make sense of the world around us. Science is one way of doing so. However, the scientific community is not immune to bias, racism, and hierarchical power structures. Yet, scientific investigation and evidence can be used as tools to challenge societal constructs, to inform policy, and to make positive change. 

Lexington High School science educators seek to provide a safe and inclusive class environment where all students have a voice and equitable access to engage with the practice of science. We commit to diversity, equity, inclusion, anti-racist and anti-bias practices because we all belong.


Welcome to Chemistry!

Here you will find information regarding Google class enrollment, homework assignments  and general information. Be sure to check back often to keep up with what is going on in class.

Please keep in mind, however, that in-class instructions regarding assignments take precedence over those listed here, in case of any discrepancy.

Notes and useful handouts will be accessible via the shared google drive folder. This year we will also be using google classroom to enhance your learning.
