  1. Research question: Which paper tower stands tallest? What variable should change?

    • sponge type
    • brace shape
    • fold pattern
    • filter material

  2. What should stay the same for this fair test: Which sponge absorbs the most water?

    • same amount of muddy water
    • same craft sticks and glue amount
    • same ramp height and cart body
    • same water volume and soaking time

  3. What should students measure during this test: Which wheel size helps a cart roll farther?

    • soil temperature in the morning
    • distance traveled after leaving the ramp
    • mass held before bending
    • clarity of the filtered water

  4. Which plan is fairest for this question: Which cover keeps soil warmer overnight?

    • change only the fold pattern and use equal materials
    • change only the brace shape and test the same load steps
    • change only sponge type and soak each sample equally
    • change only the cover type and place containers side by side

  5. Why repeat trials in a fair test about "Which bridge brace holds the most mass?"?

    • repeated data makes the result more reliable
    • one guess is stronger than data
    • trials should all change different variables
    • repetition replaces measurement

  6. Research question: Which wheel size helps a cart roll farther? What variable should change?

    • brace shape
    • sponge type
    • cover type
    • wheel size

  7. What should stay the same for this fair test: Which wheel size helps a cart roll farther?

    • same water volume and soaking time
    • same ramp height and cart body
    • same amount of muddy water
    • same craft sticks and glue amount

  8. What should students measure during this test: Which paper tower stands tallest?

    • soil temperature in the morning
    • distance traveled after leaving the ramp
    • clarity of the filtered water
    • height before tipping

  9. Which plan is fairest for this question: Which filter removes more soil from muddy water?

    • change only the fold pattern and use equal materials
    • change only sponge type and soak each sample equally
    • change only wheel size while keeping the ramp height equal
    • change only the filter material and keep the water amount the same

  10. Why repeat trials in a fair test about "Which filter removes more soil from muddy water?"?

    • repeated data makes the result more reliable
    • repetition replaces measurement
    • trials should all change different variables
    • one guess is stronger than data
