  1. Investigation 943: what happens in this magnet test: aluminum foil near a magnet?

    • not attracted
    • repel
    • attracted
    • no visible change

  2. Investigation 869: which material or object is being tested for magnetic behavior in "paper clip near a magnet"?

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

  3. Investigation 850: which design choice fits the evidence "not attracted" for aluminum foil?

    • use the foil without retesting
    • choose steel instead of aluminum
    • choose aluminum for magnetic pickup
    • assume all shiny metals attract

  4. Investigation 202: why should engineers test materials or pole arrangements such as steel paper clip before building a magnetic tool?

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

  5. Investigation 471: which question would first test magnetic behavior for wood block?

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

  6. Investigation 789: what happens in this magnet test: wood block near a magnet?

    • attracted
    • no visible change
    • repel
    • not attracted

  7. Investigation 914: which material or object is being tested for magnetic behavior in "aluminum foil near a magnet"?

    • iron nail
    • aluminum foil
    • steel paper clip
    • wood block

  8. Investigation 807: which design choice fits the evidence "not attracted" for aluminum foil?

    • assume all shiny metals attract
    • choose aluminum for magnetic pickup
    • choose steel instead of aluminum
    • use the foil without retesting

  9. Investigation 347: why should engineers test materials or pole arrangements such as two magnets before building a magnetic tool?

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

  10. Investigation 820: which question would first test magnetic behavior for two magnets?

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