Welcome to 5th Grade Science!One requirement you will have this year is Daily Oral Science, or DOS. Every week you will answer

8 questions relating to science. This is how it works:1) All the answers to these questions are located in our science textbook. You may be using

the glossary, reference pages in the back, or text located throughout the book. Use your table of contents (in the front of the book) and your index (in the back of the book) to help you located the topics found in the questions.

2) All questions should be answered and brought to class on Wednesdays, unless otherwise directed. We will discuss the correct answers to the questions on Wednesday of each week. If you do not do the work, however, you will not be allowed to participate in the discussion. This is to be fair to the students who completed their weekly assignment.

3) A test will be given on Thursday of 5 of the 8 questions. The answers are to be written using complete sentences. Since there are only 5 questions, they will each count 20 points, so be careful! We are having the test on Thursday because many tests are given on Fridays. Hopefully moving the test to Thursday will help.

4) The questions cover 5th grade SC Science Standards. You will not know the answer to every question on your own. That is why the textbook is there to help. We may have already covered the material, or it may be a preview of what is to come. Don’t fret if you don’t know the answer! Just look it up!

5) You MAY work ahead on the questions if you wish. The DOS folder is yours to keep. Just make sure you have the textbook at school each day and the DOS folder is with you on Wednesday. Please, don’t lose the DOS folder. If you lose it, it is YOUR responsibility to copy the questions from another student. You will NOT receive another folder!
