My store contains comprehensive and effective LESSON BUNDLES made for HIGH SCHOOL SCIENCE AND BIOLOGY.   These lesson bundles usually contain the following:
 

1. 1 Power Point  These power points are well sequenced and visually engaging.  Many contained hyperlinked videos. I have found that students of all different levels prefer interactive power point lessons over chalkboard lessons.
2. Power Point Worksheets  These help students organize their notes and label any diagrams or fill in charts that might be in the Power Point.  This is especially great for students who are slow at taking board notes and who need more structure to support their note taking.
3. Review Worksheets  These help reinforce concepts and gives extra practice to students who need more support.  Great as test prep.  They can easily be modified and turned into tests themselves.
4. 1 Crossword  These are designed to be a fun way to review scientific terms and force students to spell it the correct way. 
5. Flash Cards  I have found that flash cards are a great way to engage all students, especially those who like to be chatty.  Flash cards give talkative students a chance to verbalize but in constructive ways.  Using flash cards also creates an activity that promotes group learning that is student driven.  They are great to use as a review at the end of a topic as well as a good test prep.  Once you print them out and cut them...you'll have them forever and they will be your go-to activity when you find yourself with 20 extra minutes at the end of a class.
6. 1Quiz/Test  These help you easily assess how much students have learned.  I make them easy to mark and they come with answer keys.
