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

    • attracted
    • repel
    • no visible change
    • not attracted

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

    • steel paper clip
    • aluminum foil
    • two magnets
    • iron nail

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

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

  4. Investigation 331: why should engineers test materials or pole arrangements such as iron nail before building a magnetic tool?

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

  5. Investigation 858: which question would first test magnetic behavior for two magnets?

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

  6. Investigation 827: what happens in this magnet test: aluminum foil near a magnet?

    • no visible change
    • repel
    • attracted
    • not attracted

  7. Investigation 307: which material or object is being tested for magnetic behavior in "wood block near a magnet"?

    • two magnets
    • wood block
    • steel paper clip
    • iron nail

  8. Investigation 198: which design choice fits the evidence "attract" for two magnets?

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

  9. Investigation 379: why should engineers test materials or pole arrangements such as aluminum foil before building a magnetic tool?

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

  10. Investigation 483: which question would first test magnetic behavior for two magnets?

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