Question 1

A teacher wants to show magnetic force to the class from 10 meters away. What limits how the magnetic solution can work?

  1. Magnetic force gets weaker when the magnet is farther away. (correct answer)
  2. The magnet must be the teacher's favorite color.
  3. The solution should be awesome.
  4. Magnets always get stronger when they are farther away.
Explanation: The skill being assessed is 3-PS2-4, which involves defining criteria and constraints for magnetic solutions. Design criteria are the requirements that a solution must meet to be successful, while constraints are limitations such as available materials, cost, size, or safety considerations. In this problem, a teacher wants to demonstrate magnetic force from 10 meters away, so the solution must account for how distance affects magnetic strength. Choice A works because it identifies a realistic constraint like magnetic force weakening with distance, which is appropriate for 3rd-grade science, testable, and specific to the demonstration problem. The distractors fail because they are incorrect science like magnets getting stronger with distance, irrelevant like color, or too vague like being 'awesome.' To teach this, first define the problem clearly, then identify what the solution needs to do as criteria, and pinpoint limits like materials or safety as constraints. Finally, test if the criteria are measurable and ensure the constraints are realistic for the context.

Question 2

Ms. Lee wants to display 20 papers on a metal board using magnets. What constraint must the solution follow?

  1. It must hold all 20 papers using magnets that fit on the board (correct answer)

The distractors fail because B is irrelevant to magnets, C incorrectly prioritizes aluminum which isn't magnetic, and D is too vague. To teach this, first define the problem clearly, then identify what the solution needs to do as criteria. Next, identify limits like time or volume as constraints, test if criteria are measurable, and ensure constraints are realistic for the context.

Question 16

Students hang schedules inside a metal locker using magnets. Which is an important requirement for this magnetic solution?

  1. It must hold papers in place but still let students remove them easily. (correct answer)
  2. It must stick to the locker even if the locker is made of cardboard.
  3. It must use tape and pushpins instead of magnets.
  4. It must be the prettiest design in the whole grade.
Explanation: This question tests understanding of criteria for everyday magnetic solutions (3-PS2-4). Criteria define what the solution must do successfully, while constraints are limitations on how it can work. The problem is hanging schedules inside metal lockers where students need both secure attachment and easy removal. Answer A correctly identifies dual criteria: magnets must hold papers in place (secure attachment) but still let students remove them easily (accessibility), both specific and practical requirements. Answer B incorrectly assumes lockers might be cardboard (contradicting the stated metal locker), Answer C abandons magnets entirely for tape and pushpins, and Answer D focuses on appearance rather than function. Teaching tip: have students test different magnet strengths on locker doors, finding the balance between 'strong enough to hold' and 'easy enough to remove,' demonstrating how criteria often involve trade-offs.

Question 17

A sorting game has mixed toy pieces, some metal and some plastic. What criteria should the magnetic solution meet?

  1. It must pick up plastic pieces better than metal pieces
  2. It must pick up the metal pieces fast but leave plastic pieces behind (correct answer)
  3. It must be used only by the tallest student
  4. It should look cool and fun
Explanation: This question tests understanding of defining criteria and constraints for magnetic solutions (3-PS2-4). Criteria describe what the solution must accomplish to be successful, while constraints are limitations. The problem involves sorting mixed metal and plastic toy pieces using magnetic properties. Answer A correctly identifies specific criteria: pick up metal pieces quickly while leaving plastic pieces behind, utilizing the fact that magnets attract metal but not plastic. Answer B contradicts how magnets work since they cannot pick up plastic, Answer C is too vague and doesn't address the sorting function, and Answer D introduces an irrelevant user restriction. When defining criteria for magnetic sorting solutions, students should understand which materials magnets attract, create criteria that use this property effectively, and ensure criteria are specific to the sorting task.

Question 18

Cafeteria workers sort hundreds of cans daily. Which is an important requirement for a magnet sorter?

  1. It must pull steel cans but not pull aluminum cans. (correct answer)
  2. It must pull aluminum cans best because aluminum is magnetic.
  3. It should work well and be awesome at sorting.
  4. It must cook the lunch faster while sorting the cans.
Explanation: This question assesses ability to define criteria and constraints for magnetic solutions (3-PS2-4). Criteria define what makes a solution successful, while constraints set limits on the design. The cafeteria sorting problem requires separating steel cans (magnetic) from aluminum cans (non-magnetic) quickly and accurately. Answer A correctly identifies the key criterion: the magnet must pull steel cans but not aluminum cans, which is exactly how magnetic sorting works. Answer B fails because it incorrectly states aluminum is magnetic—aluminum is not attracted to magnets. Answer C is too vague ('work well and be awesome') without specific, measurable criteria. Answer D introduces an unrelated function (cooking lunch) that has nothing to do with magnetic sorting. Teaching strategy: demonstrate with actual magnets that steel sticks but aluminum doesn't, then help students write criteria based on this magnetic property difference.

Question 19

In a sorting game, kids quickly separate metal toy pieces from plastic pieces using a magnet. What criteria should the magnetic solution meet?

  1. It must attract the metal pieces and leave the plastic pieces behind. (correct answer)
  2. It must sort the toys by color, not by material.
  3. It must attract plastic pieces better than metal pieces.
  4. It should be good and work fine.

Choice A works because it identifies appropriate criteria for success, such as attracting metal and ignoring plastic, which is realistic, testable, and specific to the sorting game. The distractors fail because they are incorrect like attracting plastic better, too vague like being 'good and fine,' or wrong focus like sorting by color. To teach this, first define the problem clearly, then identify what the solution needs to do as criteria, and pinpoint limits like materials or safety as constraints. Finally, test if the criteria are measurable and ensure the constraints are realistic for the context.

Question 20

A mechanic drops small steel bolts in tight spaces. What must the magnetic solution be able to do?

  1. Turn aluminum bolts into steel bolts using magnet power
  2. Find and pull out steel bolts from hard-to-reach places quickly (correct answer)
  3. Measure tire pressure and fill tires with air
  4. Work well and be good
Explanation: This question tests ability to define criteria and constraints for magnetic solutions (3-PS2-4). Criteria specify what the solution must do to succeed, while constraints define limitations. The problem is that a mechanic needs to retrieve dropped steel bolts from tight spaces. Answer A correctly identifies specific, measurable criteria: the magnetic solution must find and pull out steel bolts from hard-to-reach places quickly, addressing the exact problem with clear success measures. Answer B is impossible because magnets cannot change one metal into another, Answer C is too vague to be useful criteria, and Answer D describes a completely different function unrelated to magnets or the stated problem. To define effective criteria for magnetic solutions, students should clearly state what the solution needs to do, make criteria specific and testable, and ensure criteria directly address the problem using magnetic properties.
