Welcome to my page!!!
I am very excited to begin teaching for a 6th year at the Multicultural Academy Charter School and 10th year overall in Philadelphia Charter Schools. It is my goal to develop scientific skills and critical thinking that will lay a foundation for further scientific studies as well inspire all of my students to be curious individuals and question the natural world that we live in. On this site you will find my weekly lesson plans and occasional handouts or assignments.
