  1. Investigation 292: what happens in this magnet test: paper clip near a magnet?

    • not attracted
    • no visible change
    • repel
    • attracted

  2. Investigation 334: which material or object is being tested for magnetic behavior in "wood block near a magnet"?

    • wood block
    • two magnets
    • steel paper clip
    • aluminum foil

  3. Investigation 339: which design choice fits the evidence "repel" for two magnets?

    • use a nonmagnetic spacer as the solution
    • turn one magnet around
    • ignore which poles face each other
    • keep the same poles facing

  4. Investigation 680: why should engineers test materials or pole arrangements such as steel paper clip before building a magnetic tool?

    • pole direction never affects results
    • all tested materials respond the same way
    • one material test proves every design
    • different tests can show attraction, repulsion, or no attraction

  5. Investigation 202: which question would first test magnetic behavior for two magnets?

    • Does the material attract, repel, or not respond?
    • Can the result be chosen before testing?
    • Should every material be treated the same?
    • Which observation should be ignored?

  6. Investigation 764: what happens in this magnet test: iron nail near a magnet?

    • repel
    • attracted
    • not attracted
    • no visible change

  7. Investigation 196: which material or object is being tested for magnetic behavior in "iron nail near a magnet"?

    • iron nail
    • wood block
    • aluminum foil
    • two magnets

  8. Investigation 507: which design choice fits the evidence "attract" for two magnets?

    • assume every pole pair repels
    • keep two north poles facing
    • place opposite poles together
    • separate the magnets before testing

  9. Investigation 661: why should engineers test materials or pole arrangements such as two magnets before building a magnetic tool?

    • one material test proves every design
    • pole direction never affects results
    • different tests can show attraction, repulsion, or no attraction
    • all tested materials respond the same way

  10. Investigation 400: which question would first test magnetic behavior for wood block?

    • Which observation should be ignored?
    • Does the material attract, repel, or not respond?
    • Should every material be treated the same?
    • Can the result be chosen before testing?
