Magnets and Engineering Design

Grade 3 - Science - Challenge Me

Worksheet 1

  1. Investigation 324: what happens in this magnet test: wood block near a magnet?

  2. Investigation 974: which material or object is being tested for magnetic behavior in "north pole facing south pole"?

  3. Investigation 862: which design choice fits the evidence "repel" for two magnets?

About this worksheet

Magnets and engineering design connect force observations with solutions to practical problems helps third graders connect observations with scientific explanations instead of memorizing isolated facts. Students may think magnets attract every material, or they may choose a design before checking evidence from tests. This worksheet uses short evidence-based situations so students must read the setup, identify the pattern, and choose the answer that fits the science idea named in the title. Students identify attraction and repulsion, compare magnetic materials, interpret test results, and choose designs that fit the evidence. Support versions use familiar examples and direct wording. Standard and challenge versions add closer distractors and require more comparison. Encourage your child to point to the evidence in the prompt before choosing an answer. If the answer does not explain the observation or solve the stated problem, it is probably a distractor. That habit builds careful science reasoning and prepares students for longer investigations.

What your child will learn

  • Identify magnetic attraction
  • Recognize repulsion
  • Use test evidence
  • Choose design solutions

Worked example

A steel paper clip is attracted to a magnet, so a magnet can help pick up spilled clips.

Common mistake

Assuming every metal is attracted to a magnet.

Helpful hint

Use the test result before choosing the design.

Forces and Motion
