Read about the situation. Students want to read library books during recess outside. Books can get dirty or wet on the grass, and Maya says, “I don’t want to ruin a library book.” The solution must use classroom materials, be safe, and fit in a desk or backpack. What challenge needs to be solved, and what makes solving it difficult?
Design a way to protect library books outdoors while using safe classroom materials that fit in a desk or backpack.
Design a new library with more books so students can replace damaged ones.
Design a plan to use safe materials and make it fit in a backpack.
Design a rule that students must keep books inside the library at recess.
Explanation
This question tests the ability to identify a design problem with criteria and constraints (NGSS 3-5-ETS1-1: Define a simple design problem reflecting a need or want that includes specified criteria for success and constraints on materials, time, or cost). A design problem is a challenge that needs solving through creating something new or improving something existing. Good design problem statements include WHAT needs to be solved (the need or want) and awareness of LIMITS on solutions (constraints like materials available, time to build, or cost). For example, "design a way to keep plants watered using free materials" identifies both problem (watering plants) and constraint (free materials). In this scenario, students read library books outside at recess, but books get dirty or wet on the grass. The main challenge is protecting library books outdoors, and students must recognize that any solution will be limited by using classroom materials, being safe, and fitting in a desk or backpack. Choice A is correct because it identifies both the design challenge (a way to protect library books outdoors) and acknowledges constraints (safe classroom materials that fit in a desk or backpack). This shows understanding that design problems aren't just "make something" but "make something that solves a specific need within certain limits." Choice D represents focusing on constraints without stating what needs designing. Students who choose this may think listing materials is the same as stating the problem. To help students: Use the question "What needs to be designed and what are the limits?" Have students underline the problem (what needs solving) in one color and constraints (materials, time, cost limits) in another color. Practice distinguishing between describing a situation versus identifying a design challenge.
Read about the situation. During outdoor reading time, books and papers fall or get wet on the way to the playground. Jamal says, “My pages got soggy again!” Students need a solution using classroom materials that is safe and quick to use in under 5 minutes. Which statement identifies both the problem and what limits the solution?
Design something that is made from recycled materials and takes less than 5 minutes to use.

Sofia says, “My milk almost fell off again!” Students need a solution that is safe, uses classroom materials, and is quick to use in under 5 minutes. Which describes what needs to be designed and what constraints must be considered?
Design a way to carry lunch items safely on a tray using classroom materials, and it must be quick to use.

This shows understanding that design problems aren't just "make something" but "make something that solves a specific need within certain limits." Choice A represents an overly broad or unrelated solution like redesigning the entire cafeteria. Students who choose this may think big changes are needed instead of targeted designs within constraints. To help students: Use the question "What needs to be designed and what are the limits?"

Design a better way to carry lunch items safely using classroom materials and fitting on a tray.
Design a rule that students must walk slower in the cafeteria.
Design a bigger cafeteria with more tables and chairs.

Design a way to keep soil moist between meetings using safe, reused materials we already have.
Design a tool that digs deeper holes so plants grow faster.
Design something safe and free, but do not say what it is for.
Design a schedule so students can meet in the garden every day after school.

What challenge needs to be solved, and what makes solving it difficult?
Design a water system that uses metal tools and drilling to attach new parts.
Design something safe and smooth, but do not include any water needs.
Design a way to give the hamster water all day using safe materials we already have, with no sharp edges.

Design a storage system that sorts art supplies and fits on a shelf, using only free or recycled materials.
Design a plan to buy new markers and scissors for every student.
Design a shelf that is taller than the students so it holds everything.
