Are you interested in learning about the world around you? Do you ever wonder how scientist study the world and understand its' beauty?  This 18 week self paced course will provide you the foundation of High School Biology concepts.  We will explore important scientists who laid the groundwork for the progression of science today.  Be ready to learn the important techniques,  methods, and principles of understanding the world around you.  We will look into for major units of study: cells, genetics, evolution and ecology.  I will teach you the terminology, application to scenarios, real world data analysis, problem-solving, and understanding the relationships of the concepts.  This class will cover the main areas of study that I typically teach in a traditional class setting.  This class does require you to complete activities or worksheets outside of class. 

Students will have the opportunity to have class discussions in a weekly forum on related topics.  They will also be able to share summaries or graphic organizers with their peers via the classroom tab.  This class is a self paced class set up and all post/communication will be made directly in the Outschool Classroom.   Students can submit work via private classroom message. Students will be asked to answer relevant questions, based in their opinion, and discuss with peers what or why they find most interesting revolving the weekly content. Additionally,  optional homework will be provided for students who would like to extend on the lesson.  Students will have the option of a midterm assessment and a final assessment for the course.   

Materials vary per week.  The week of class you will receive materials ranging from guided notes, interactive activities, a copy of the vocabulary, worksheets, and a hyperdoc page with website links.   Additional resources will be available to further practice outside of class.  We will interact directly on the Outschool Classroom and use other resources as supplementary tools. 

The objective of this class is to cover the majority of the year of Biology concepts that you would typically encounter in a High School Biology setting.  This class does not include lab work.  I do offer a separate course for Biology labs.  

Students will participate in class each week by watching the video lesson, engage in interactive activities, then they will participate in peer discussion questions on the classroom page, and engage in pair and share opportunities to allow for more peer to peer engagement.  Finally,  I will send feedback and support opportunities on homework/discussion/pair and shares, and vocabulary practice.
