AP Summer Assignment/Expectations

Student Expectations
• Do one hour of homework every night and come to class prepared
• Be prepared with assignments
• Show the extra commitment that lab work may require (possible before/after school to complete lab work)
• Follow the safety and behavior requirements of the course
• Attend any extra study/review periods that are held during the year
• Be responsible for making up any work that is missed
• Complete any summer or vacation assignments that may be required



The Goals of AP Biology:
1.) Get you ready for college science classes.
2.) Have you score a 3, 4, or 5 on the AP Biology test to save you money and time in college.
3.) Keep you moving and motivated on your path to improve the world.

This Summer's Assignment is to...
1.) Read the "Genius in All of Us." Available used on Amazon. Also available at the New Carlisle Library.
Focus on the impacts our behavior and environment have on our own genes.
Focus on the section about track and field runners.
Answer the questions on the handout for AP Summer Reading Assignment.

2.) Review and know the vocabulary list.
Most of these words are from freshman biology. Knowing them will help throughout AP Biology and also on the quiz that is the second day of school next fall.

3.) Sign Up for a school appropriate Google Account.

4.) Sign Up for Edmodo.com "I'm a student" Group Name: GensicAPBiology Code: snk7ya
Go to notifications, sign up to get Alerts sent straight to your cell phone.

5.) Questions? Post a Comment to this blog.

6.) Optional: Get a AP Biology Study Book/App. There are many AP Biology Study Apps on the App Store. I don't know enough about these to endorse one. Read the reviews, look at the App previews. Studying more will only help you.
