Welcome to Chemistry and Biology!

Students, Parents, and Guardians,


Welcome to back to school! I am Mrs. Todd, and I am very excited for the school year. I teach both biology and chemistry. These courses will aid you to understand the marvels of the universe, the composition of matter, and comprehend the changes that are occurring around us.


Each day we will strive to draw connection points between content and relevant topics in today’s society. Parents, please encourage your son or daughter to actively participate in class, complete all assignments thoughtfully and on time, and to study regularly outside of class.Please feel free to contact me at any point by email or phone.
