This question tests the skill 2-PS1-2: Testing materials and recording observations to find which is best for a purpose. Scientists test materials to find which works best. We decide what property we need—strong, waterproof, flexible, absorbent. We test each material the same way. We record observations or measurements. Then we compare results to find which material is best for our purpose. In this test, Chen wanted to find which material is best for cleaning spills. He tested paper towel, cotton, plastic, and foil by dipping each in water for 10 seconds. He measured how many drops each material soaked up. The correct answer is C (Paper towel soaked 12 drops) because the test results show paper towel soaked up the most water. Paper towel soaked 12 drops, which means it is the most absorbent and best for cleaning spills. When we look at the data, paper towel performed better than cotton (9 drops) and much better than plastic or foil (0 drops). Choice B (Foil soaked 0 drops) is incorrect because foil didn't soak up any water, making it the worst for cleaning spills. This error happens when students confuse the purpose—they might think 0 is good when actually we want the highest number for absorption. To help students analyze tests: First identify PURPOSE—what are we trying to find? Then find which material BEST achieved that purpose using the data. Teach students to read tables/charts—find material name, then find result. Practice comparing numbers—'12 is more than 9, so paper towel soaked more than cotton.' Use sentence frames: 'The test shows paper towel soaked 12 drops. This means paper towel is best for cleaning spills.' Emphasize data over opinion—'I like plastic better' doesn't matter; 'paper towel soaked 12 drops' is the data. Watch for: Students who choose 0 thinking less is better, or who confuse materials. Have students point to specific data that supports their answer.

This question tests the skill 2-PS1-2: Testing materials and recording observations to find which is best for a purpose. Scientists test materials to find which works best. We decide what property we need—strong, waterproof, flexible, absorbent. We test each material the same way. We record observations or measurements. Then we compare results to find which material is best for our purpose. In this test, Yuki wanted to find which material is best for a raincoat. She tested paper, fabric, plastic, and rubber by putting 3 drops of water on each. She observed how water behaved on each material—soaking in or staying on top. The correct answer is B (Water soaked in fast) because the test results specifically state that water soaked into paper fast. This observation shows paper absorbs water quickly, making it unsuitable for a raincoat. When we look at the data, paper performed the worst by letting water soak in fast. Choice A (Water stayed on top) is incorrect because the results clearly state water soaked into paper, not stayed on top. This error happens when students confuse which material had which result or misread the data table. To help students analyze tests: First identify what the question asks—what happened to paper specifically? Then find paper's result in the data. Teach students to match material names with their results carefully. Practice reading observations—'soaked in fast' is different from 'stayed on top.' Use sentence frames: 'The test shows water soaked into paper fast. This means paper is not good for a raincoat.' Emphasize careful reading—each material has its own result. Watch for: Students who mix up results between materials or assume all materials behave the same way. Have students point to the specific observation about paper in the results.

This question tests skill 2-PS1-2: Testing materials and recording observations to find which is best for a purpose. Scientists test materials to find which works best. We decide what property we need—strong, waterproof, flexible, absorbent. We test each material the same way. We record observations or measurements. Then we compare results to find which material is best for our purpose. In this test, students wanted to find which material is best for building a bridge. They tested paper, cardboard, wood, and plastic by stacking books until each material bent. They recorded how many books each could hold. The correct answer is C (Wood) because the test results show wood held the most books before bending. Wood held 8 books, which means it is the strongest and best for building a bridge. When we look at the data, wood performed better than all other materials tested. Paper is incorrect because it only held 1 book, making it the weakest material and worst choice for a bridge. This error happens when students don't look at the data or choose based on what they think bridges look like. To help students analyze tests: First identify PURPOSE—what are we trying to find? Then find which material BEST achieved that purpose using the data. Teach students to compare all numbers—'8 is more than 6, 4, and 1, so wood is strongest.' Practice connecting test results to purpose—strongest material makes the best bridge. Use sentence frames: 'The test shows wood held 8 books. This means wood should be used for the bridge.' Emphasize data over opinion—'I've seen paper bridges' doesn't matter; 'wood held 8 books' is the data. Watch for: Students who choose based on real bridges they've seen, pick the first or last option, or don't compare all the numbers. Have students point to specific data that supports their answer.

This question tests the skill 2-PS1-2: Testing materials and recording observations to find which is best for a purpose. Scientists test materials to find which works best. We decide what property we need—strong, waterproof, flexible, absorbent. We test each material the same way. We record observations or measurements. Then we compare results to find which material is best for our purpose. In this test, Amir wanted to find which material is best for a bending toy. He tested wire, straw, ribbon, and craft stick by bending each until it broke. He measured how many centimeters each material could bend. The correct answer is B (Ribbon bent 15 cm) because the test results show ribbon bent the most. Ribbon bent 15 cm, which means it is the most flexible and best for a bending toy. When we look at the data, ribbon performed better than wire (12 cm), straw (6 cm), and craft stick (1 cm). Choice A (Craft stick bent 1 cm) is incorrect because craft stick bent the least, making it the stiffest material. This error happens when students choose the smallest number or confuse which property is being tested. To help students analyze tests: First identify PURPOSE—what are we trying to find? Then find which material BEST achieved that purpose using the data. Teach students to read tables/charts—find material name, then find result. Practice comparing numbers—'15 is more than 12, so ribbon bent more than wire.' Use sentence frames: 'The test shows ribbon bent 15 cm. This means ribbon is best for a bending toy.' Emphasize data over opinion—'I like sticks better' doesn't matter; 'ribbon bent 15 cm' is the data. Watch for: Students who choose based on familiarity or preference, misread numbers, or think smaller numbers are better. Have students point to specific data that supports their answer.

This question tests skill 2-PS1-2: Testing materials and recording observations to find which is best for a purpose. Scientists test materials to find which works best. We decide what property we need—strong, waterproof, flexible, absorbent. We test each material the same way. We record observations or measurements. Then we compare results to find which material is best for our purpose. In this test, Keisha wanted to find which material is best for a raincoat. She tested paper, fabric, plastic, and foil by putting 3 water drops on each material. She observed what happened to the water on each material. The correct answer is B (Water stayed on top of plastic) because this accurately describes what students observed about plastic. The observation shows that plastic kept water from soaking through, making it waterproof. When we look at the data, this matches what was recorded—water stayed on top of plastic, just like with foil. The other choices are incorrect observations about plastic. This error happens when students confuse observations between different materials or misunderstand what makes a material waterproof. To help students analyze tests: First identify what the question asks—what did we observe about plastic specifically? Then find that observation in the data. Teach students to match material names with their results carefully. Use sentence frames: 'The test shows water stayed on top of plastic. This observation tells us plastic is waterproof.' Emphasize reading data accurately—don't mix up results from different materials. Watch for: Students who choose observations that belong to other materials, like 'soaked in fast' which was paper's result.

We decide what property we need—strong, waterproof, flexible, absorbent. We test each material the same way. We record observations or measurements. Then we compare results to find which material is best for our purpose. In this test, students wanted to find which material is best for a strong bridge to hold books. They tested paper, cardboard, wood, and plastic by putting books on each until it bent. They measured that paper held 2, cardboard 6, wood 10, and plastic 7 books. The correct answer is C because the test results show wood held 10 books, the highest number, meaning it is strongest and best for the bridge. Choice B is incorrect because paper held only 2 books, the worst performer; this error happens when students misread data or reverse observations. To help students analyze tests: First identify PURPOSE—what are we trying to find? Then find which material BEST achieved that purpose using the data. Teach students to read tables/charts—find material name, then find result. Practice comparing numbers—'12 is more than 3, so wood held more than paper.' Use sentence frames: 'The test shows [material] [result]. This means [material] is best for [purpose].' Emphasize data over opinion—'I like plastic better' doesn't matter; 'plastic held 15 books' is the data. Watch for: Students who choose based on familiarity or preference, misread numbers, confuse materials, or reverse observations. Have students point to specific data that supports their answer.

Then we compare results to find which material is best for our purpose. In this test, students wanted to find which material is best for a floor that does not scratch easily. They tested wood, rock, metal, and plastic by scratching with a fingernail. They observed wood scratched, rock not scratched, metal not scratched, plastic scratched. The correct answer is B because the test results show wood scratched, meaning it scratched easily. Choice C is incorrect because soaking water confuses the property being tested, which is scratching not absorbing. To help students analyze tests: First identify PURPOSE—what are we trying to find? Then find which material BEST achieved that purpose using the data. Teach students to read tables/charts—find material name, then find result. Practice comparing numbers—'12 is more than 3, so wood held more than paper.' Use sentence frames: 'The test shows [material] [result]. This means [material] is best for [purpose].'

This question assesses the skill 2-PS1-2: Testing materials and recording observations to find which is best for a purpose. Scientists test materials to find which works best by deciding what property is needed—such as being strong, waterproof, flexible, or absorbent—testing each material the same way, recording observations or measurements, and comparing results to determine the best for the purpose. In this test, students wanted to find which material keeps water out, so they tested paper, fabric, plastic, and foil by putting 3 drops on each and observed what happened to the water, with it soaking into paper and fabric, but staying on top of plastic and foil. The correct answer is B because the test results show water stayed on top of plastic, meaning it is waterproof and repels water, and when we look at the data, this observation confirms plastic's property for keeping water out. Choice A, water soaked into plastic, is incorrect because the data shows the opposite—it stayed on top—and this error happens when students reverse the observations or misread the results. To help students analyze tests, first identify the purpose—what are we trying to find?—then find which material best achieved that purpose using the data, and teach students to read tables or charts by finding the material name and then the result. Practice comparing observations like 'stayed on top is better than soaked in for keeping dry,' use sentence frames such as 'The test shows water stayed on top of plastic, this means plastic keeps water out,' emphasize data over opinion—'I think it soaked in' doesn't matter, the observation is the data—and watch for students who choose based on preference, misread results, confuse materials, or reverse observations, having them point to specific data that supports their answer.

Then we compare results to find which material is best for our purpose. In this test, students wanted to find which material is best for cleaning up spills. They tested paper towel, cotton, plastic, and foil by dipping each piece in water and counting drops soaked up. They recorded how many drops each material absorbed. The correct answer is C (Paper towel soaked 12 drops) because the test results show paper towel absorbed the most water. Paper towel soaked up 12 drops, which means it is the most absorbent and best for cleaning spills. When we look at the data, paper towel performed better than all other materials. Plastic soaked 0 drops is incorrect because this shows plastic absorbed no water, making it worst for cleaning spills. This error happens when students confuse most absorbent with least absorbent or misread the data. To help students analyze tests: First identify PURPOSE—what are we trying to find? Then find which material BEST achieved that purpose using the data. Teach students to read tables—find material name, then find drops absorbed. Practice comparing numbers—'12 is more than 9, so paper towel absorbed more than cotton.' Use sentence frames: 'The test shows paper towel soaked 12 drops. This means paper towel is best for cleaning spills.' Emphasize data over opinion—'I use plastic cups' doesn't matter; 'plastic soaked 0 drops' is the data. Watch for: Students who think 0 is good for absorption, confuse materials, or choose based on home experience. Have students point to specific data that supports their answer.
