[{"role": "user", "question": "Identify the question that Madelyn and Tucker's experiment can best answer.", "answer": "B", "options": {"A": "Does Madelyn's snowboard slide down a hill in less time when it has a thin layer of wax or a thick layer of wax?", "B": "Does Madelyn's snowboard slide down a hill in less time when it has a layer of wax or when it does not have a layer of wax?"}, "choices": ["A", "B"], "hint": "The passage below describes an experiment. Read the passage and then follow the instructions below.\n\nMadelyn applied a thin layer of wax to the underside of her snowboard and rode the board straight down a hill. Then, she removed the wax and rode the snowboard straight down the hill again. She repeated the rides four more times, alternating whether she rode with a thin layer of wax on the board or not. Her friend Tucker timed each ride. Madelyn and Tucker calculated the average time it took to slide straight down the hill on the snowboard with wax compared to the average time on the snowboard without wax.\nFigure: snowboarding down a hill."}]

[{"role": "user", "question": "Which of the following could Laura and Isabella's test show?", "answer": "B", "options": {"A": "if the concrete from each batch took the same amount of time to dry", "B": "if a new batch of concrete was firm enough to use"}, "choices": ["A", "B"], "hint": "People can use the engineering-design process to develop solutions to problems. One step in the process is testing if a potential solution meets the requirements of the design.\nThe passage below describes how the engineering-design process was used to test a solution to a problem. Read the passage. Then answer the question below.\n\nLaura and Isabella were making batches of concrete for a construction project. To make the concrete, they mixed together dry cement powder, gravel, and water. Then, they checked if each batch was firm enough using a test called a slump test.\nThey poured some of the fresh concrete into an upside-down metal cone. They left the concrete in the metal cone for 30 seconds. Then, they lifted the cone to see if the concrete stayed in a cone shape or if it collapsed. If the concrete in a batch collapsed, they would know the batch should not be used.\nFigure: preparing a concrete slump test."}]

[{"role": "user", "question": "Which of the following was a dependent variable in this experiment?", "answer": "A", "options": {"A": "the temperature of the soda", "B": "the size of the ice pieces"}, "choices": ["A", "B"], "hint": "The passage below describes an experiment. Read the passage and think about the variables that are described.\n\nArianna's brother thought that crushed ice would keep his soda cooler than whole ice cubes.\nTo test this idea, Arianna divided a large bottle of soda equally among six glasses. Arianna added five whole ice cubes to each of the first three glasses while her brother crushed five ice cubes into small pieces before adding them to each of the other three glasses. Ten minutes after all the ice had been added to the glasses, Arianna used a thermometer to measure the temperature of the soda in each glass.\nHint: An independent variable is a variable whose effect you are investigating. A dependent variable is a variable that you measure.\nFigure: glasses of soda with ice."}]

[{"role": "user", "question": "Which of the following was an independent variable in this experiment?", "answer": "B", "options": {"A": "the distance the footballs traveled", "B": "the air pressure in the footballs"}, "choices": ["A", "B"], "hint": "The passage below describes an experiment. Read the passage and think about the variables that are described.\n\nBryce noticed that some of the footballs his team used during practice were not fully inflated. He wondered whether fully inflated footballs would travel farther than footballs with a lower air pressure.\nTo find out, Bryce collected 20 standard footballs. He fully inflated ten of them to an air pressure of 13 pounds per square inch. He inflated the remaining ten to an air pressure of 10 pounds per square inch. Bryce used to launch a ball across a football field. He measured the distance the football traveled and then launched the next ball. Bryce repeated this with all 20 balls.\nHint: An independent variable is a variable whose effect you are investigating. A dependent variable is a variable that you measure.\nFigure: a football launcher."}]

[{"role": "user", "question": "Which of the following could Devin's test show?", "answer": "A", "options": {"A": "if the weather station would work when the temperature was 50°C", "B": "how well the weather station would work when it was windy"}, "choices": ["A", "B"], "hint": "People can use the engineering-design process to develop solutions to problems. One step in the process is testing if a potential solution meets the requirements of the design.\nThe passage below describes how the engineering-design process was used to test a solution to a problem. Read the passage. Then answer the question below.\n\nDevin was a mechanical engineer who was designing to record temperature, precipitation, and wind speed. The weather station would be used in a town where the highest recorded temperature was 40°C. Devin wanted to make sure the weather station would work even in unusually warm weather.\nSo, he set an indoor test chamber to 50°C with low moisture and no wind. He left the weather station in the chamber overnight. The next day, he checked to see if the weather station displayed accurate measurements after 24 hours at 50°C.\nFigure: a weather station."}]

[{"role": "user", "question": "Identify the question that Carson's experiment can best answer.", "answer": "B", "options": {"A": "Does the type of flour used in the muffins affect the number of muffins that turn brown after 30 minutes in the oven?", "B": "Do muffins made with white flour have larger volumes than muffins made with whole wheat flour?"}, "choices": ["A", "B"], "hint": "The passage below describes an experiment. Read the passage and then follow the instructions below.\n\nCarson made six batches of muffins over the course of one day. He used whole wheat flour in three of the batches and white flour in the other three batches. He divided the batter into muffin tins, using two ounces of batter per muffin. He baked the muffins in a 350°F oven for 20 minutes. After allowing the muffins to cool, Carson measured the dimensions of the muffins and calculated their volumes. He compared the volumes of the muffins made with whole wheat flour to the volumes of the muffins made with white flour.\nFigure: muffins cooling."}]
