 Update your Table of Contents for today  We will be completing practice EOG questions each day for warm-up, so please start on page 18 and keep adding to it each day…so, number 1-15 for today’s questions! DateSession # ActivityPage # 5/1013 Science EOG Practice Questions (keep adding to them each day) 18

 Monday after school until 5:00 to review the Periodic Table and Chemistry first and then anything else that you want to go over…PLEASE COME WITH SPECIFIC QUESTIONS

 Students need to be able to read carefully and analyze exactly what the question is asking them  Students need to know content vocabulary  Students need to be able to eliminate answer choices
