This test has two sessions that contain different types of questions. Today you will take Session 1. This session includes a combination of standalone questions and sets of questions based on a common task or scenario. Some questions will have answer choices that begin with letters. Circle the letter of each correct answer. Other questions will ask you to circle, write or show your answers. Read each question carefully and follow the directions. Mark all your answers in your test booklet.  \n1. A student creates a ball-and-stick model to represent the atomic scale of a substance.  \nStudent Model  \nWhich of these best describes the model?  \nA. 1 molecule with 10 atoms  \nB. 1 element with 10 molecules  \nC. 10 molecules representing 10 elements  \nD. 10 elements representing 10 molecules  \n2. The drawings show two waves.  \nWave 1 Wave 2  \nWhich statement best compares these two waves?  \nA. Wave 1 has a higher frequency because it has a longer wavelength than wave 2 .  \nB. Wave 1 has a higher frequency because it has a higher amplitude than wave 2 .  \nC. Wave 2 has more energy because it has a higher amplitude than wave 1 .  \nD. Wave 2 has more energy because it has a higher frequency than wave 1 .  \nPage 4 Go on to the next page.  \n3. Circle a word in each set of options to best describe relationships between interacting parts of the human body.  \nThe human body is composed of systems with interacting parts. Organ systems are made of ( organs / organelles / tissues ), which are composed of specialized cells that work together to form ( organs / organelles / tissues ) . Each cell of the human body contains  \n( organs / organelles / tissues ) with a specific function.  \nPage 5 Go on to the next page.  \n4. During an experiment, a teacher uses a flashlight and shines the light toward a pane of clear glass with a black iron backing. A diagram of the experiment is shown.  \nLight Experiment  \nair  \n\n| clear glass | black iron |\n| --- | --- |\n\n\n| Part A: Describe the path of the light as it travels from the flashlight to the air. |\n| --- |\n|  |\n|  |\n|  |\n|  |\n\n\n| Part B: Describe the path of the light as it travels from the air to the pane of clear glass. |\n| --- |\n|  |\n|  |\n|  |\n|  |\n\nPage 6 Go on to the next page.  \n4. Continued. Please refer to the previous page for task explanation.  \n\n| Part C: Explain why the students would not see the light travel through the black iron backing. |\n| --- |\n|  |\n|  |\n|  |\n|  |\n\nPage","cbCaiiWN70pnRWEt","https://ap.wps.com/l/cbCaiiWN70pnRWEt","pdf",2459050,48,"English","# Session 1: Science Directions\n## Questions 1-3\n## Light experiment (Question 4)\n## Rock layers and fossils (Question 5)\n## Solar system model (Question 6)","[{\"question\":\"How should students record answers in this Grade 8 Science practice form?\",\"answer\":\"Students follow the directions for each question, circle correct letters when choices are provided, and circle/write/show other required responses.
