Project #___: Unit 1: The Nature of Science Reading Packet Name: _____________________________ Core 1 2 3 4 Points ____/100 pts On-time In high school and beyond, you will be expected to take more and more responsibility for your own learning. Reading assignments will be a common expectation. We will be doing active reading assignments using textbooks, throughout the year, to help you get ready. These activities will: 1) help you learn how to take guided notes and summaries as you read a textbook; 2) improve your non-fiction reading comprehension skills; 3) prepare you to more fully participate in class discussions, activities and labs; 4) help you get better grades, now, and going forward.

Before you begin your reading assignment, preview the text pages and your reading packet section. 2. Next, read each sub-section completely, and then, go back and complete your notes in the packet. 3. Do NOT try to skim the reading to just fill-in-the-blanks. That approach won’t really save you much time, and you will not get nearly the same kind of benefit from the exercise.
