Welcome back!  Please check these pages often for postings about lessons, activities, labs, projects, homework and tests if you are absent for any reason.Periodically, I will also be posting videos, weblinks and various documents to help you understand the course materials.  Please do NOT get behind.  Check with me every day if there is something you are unsure about.  Many times in Science courses, one day builds on previous days and if you are not careful, problems can snowball quickly!
