Magnetic latch design gives students a practical way to explore how engineers define a problem before choosing or improving a solution. In this Science reading organizer resource, students examine how a magnetic latch can keep a cabinet door closed while still allowing a person to open it by hand.

Explore the problem before designing a solution

Students consider the purpose of a magnetic latch and the conditions that affect whether it works well. They investigate how a magnet attracts a metal plate, why the latch needs to hold the door shut, and why it must not be too difficult to open. These examples introduce the engineering practice of defining a design problem around a real need.

The reading set also distinguishes success criteria from constraints. Students consider requirements such as keeping a door closed when gently bumped, allowing a child to open it with a reasonable pull, and fitting the latch into a small space near the door edge. They explore material limits involving a magnet, metal plate, cardboard, and tape.

What students work on

• Identify the main idea in short informational passages about magnetic latch design.
• Select supporting details that explain the design need, requirements, or limitations.
• Recognize how a magnet and metal plate help a latch hold a door closed.
• Explain possible design failures, including a magnet placed too far away, a latch that is too strong, or parts that shift.
• Connect a design problem statement to the need, success criteria, and material constraints.

Each reading is paired with a graphic organizer where students record the main idea and supporting details. The task focuses on reading for important information and using evidence from the passage, while the engineering examples give students concrete ideas to think about.

Included in the resource

• Informational reading passages about defining a magnetic latch design problem.
• Main idea and supporting details graphic organizers.
• Passage content covering design needs, success criteria, material constraints, failure points, and problem statements.

No separate answer key, teacher guide, or additional activity is specified in the provided resource details.

Ways to use it in class

Use the magnetic latch reading worksheets during a Science lesson on engineering design, as guided practice in identifying main ideas, or for independent reading and organizer work. The passages can also introduce discussion about what a design must do, which materials are allowed, and why a first attempt might fail. Students can use the final problem-statement focus to bring the need, criteria, and constraints together in a clear description of the challenge.

This resource connects informational-text skills with a specific engineering situation. Instead of identifying supporting details in an unrelated passage, students work with concrete design decisions and limitations that help explain how an engineering problem is defined.
