INTRODUCTION TO SCIENCE SAMPLE TESTS and TEST KEYS The Oregon Department of Education provides sample tests in science to demonstrate the content and types of questions students who are tested at Grade 5/Benchmark 2, Grade 8/Benchmark 3 and High School might encounter on the Oregon Statewide Assessment called Oregon Assessment of Knowledge and Skills (OAKS). Items on the sample test were taken from earlier years’ Statewide Assessments and have been aligned to the 2009 Science Content Standards. These items are no longer secure and have been released for public use. Science assessment items are designed to measure students’ knowledge and skills about the physical and living universe in the following categories. Structure and Function of f Physical Science; f Life Science; and f Earth and Space Science. Interaction and Change of f Physical Science; f Life Science; and f Earth and Space science. Scientific Inquiry Engineering Design WHY PROVIDE SAMPLE TESTS? Most students feel some anxiety as they approach a test. The more confident students feel about their knowledge of the topic, the less anxious they feel. It also may help students feel comfortable if they are familiar with the test format. Teachers want to know how the state content standards are represented on these tests. This sample test helps teachers see the multiple choice format used for test questions on the OAKS online assessment.

HOW TO USE THE SAMPLE TEST The Oregon Department of Education periodically updates paper sample tests and also provides a fully adaptive practice test at http://www.oaks.k12.or.us/. To ensure complete readiness for the OAKS online assessment, students are encouraged to access the online practice test. A list of test-taking tips for students follows this introduction. Teachers may use the tips to: f generate individual and class discussion; f call attention to helpful strategies students can use to prepare for test questions; and f share ideas with parents of ways to help reduce test anxiety and promote good study habits at home. An answer key for this sample test is provided at the end of this sample test. In addition to the correct answers, the key also identifies which of the reporting categories each question is designed to assess. A table following the answer key shows how students are likely to perform on the Statewide Assessment given their answers on this sample test. This is only a short practice test. It is not an absolute predictor of how a student will do on the OAKS online assessment. Teachers may have students take the sample test, score each item, and discuss any or all of the items and answers. Students usually benefit from analyzing both the correct and incorrect answers. Sample tests also may be shared with parents to help them understand some of the types of questions their child will encounter on the test. Sample test questions may be reprinted in newsletters or shared at community meetings to better understand the state assessment system. Although the sample tests are not as comprehensive as the actual tests, they do provide a sampling of the subject area content and difficulty level students will encounter as part of Oregon’s science assessment. i
TEST-TAKING TIPS S tud ent s: Us e th es e t ips to he lp you p re par e fo r th e te st.
BEFORE THE TEST f Develop a positive attitude. Tell yourself, “I will do my best on this test.” f Get a good night’s sleep the night before the test. f Get up early enough to avoid hurrying to get ready for school. f Eat a good breakfast (and lunch, if your test is in the afternoon). DURING THE TEST f Stay calm. f Listen carefully to directions from the teacher. f Ask questions if you don’t understand what to do. f Before you read an item on the test, preview the questions that follow for tips to help you focus your reading. f After reading an item, read the entire first question and all the answer choices. Stop and think of an answer. Look to see if one of the choices is similar to your answer. f Read each test question and all the answer choices carefully. Try to analyze what the question is really asking.
f This is not a timed test. If you need more time to finish the test, tell your teacher. f If you are not sure of an answer to a question, try these tips: f Get rid of the answers you know are not correct and choose among the rest. f Read through all the answers very carefully, and then go back to the question. Sometimes you can pick up clues just by thinking about the different answers you have been given to choose from. f If you get stuck on a question, skip it and come back later. f It is OK to guess on this test. Try to make your best guess, but make sure you answer all questions. AFTER THE TEST f Before you submit your test, check it over. Change an answer only if you have a good reason. Generally, it is better to stick with your first choice. f Make sure you have marked an answer for every question, even if you had to guess. f Don’t worry about the test once it is
finished. Go on to do your best work on your other school assignments.
f Pace yourself. If you come to a difficult question, it may be better to skip it and go on. Then come back and really focus on the difficult questions one at a time.

Science▼ DIRECTIONS Read each of the questions and decide on the BEST answer. There are many different kinds of questions, so read each one carefully before marking an answer on your answer sheet. When there is an introduction to a set of questions, read it carefully, since it will contain important information you may need.
BUOYANCY Figure 1 shows a toy submarine being held beneath the water surface. The weight of the submarine, 0.5 Newton (N), tends to pull the submarine to the bottom of the container. A buoyant force of 0.8 N, created by the volume of water displaced by the submarine, tends to push the submarine toward the surface.

the sub will rise toward the surface. the sub will sink toward the bottom. the sub will stay at the same level. we can’t tell what the sub will do from this data.
2 You are given a flask with a mixture of salt and water and asked to separate the two. You could A. B. C. D.
use an electric current to separate the salt from the water. evaporate the water and collect the salt. put it under the microscope to separate the salt and water. let the salt settle out and pour off the pure water from the top.

COASTING BICYCLES Alfredo and his friends rode their bikes on a bike path. The path was perfectly level, except where it went up over a small bridge and then came back down. There was no wind. The picture below shows a side view of the shape of the path they followed. They had a contest to see who could coast the farthest. They pedaled as fast as they could from point 1 to point 2, and then they stopped pedaling and coasted to a stop at point 7. BRIDGE 4 1
