Water soaked up (model data)
Towel Trial 1 Trial 2 Trial 3 A 30 mL 32 mL 31 mL B 40 mL 20 mL 33 mL Jun tested two paper towels three times each. Which statement fits the data?
- B's results are the steadier of the two
- Both average 31 mL, but A's results are steadier
- A soaked up more water on average than B in these tests
- B soaked up more, since 40 mL is the top value
Kira grew bean plants with and without plant food. Which statement does the graph support?
- Plant food doubles the growth of any plant it touches
- The gap grew each week, reaching 5 cm by week 3
- The gap between the groups was 13 cm at week 3
- The plants without plant food grew faster
Luz's friend sees an empty cracker jar and says, "The crackers were eaten" is an observation. Which response is best?
- Agree: it is obvious, so it counts as observed
- Disagree: the empty jar is an inference too
- Agree: anything you think about it is an observation
- Disagree: the empty jar is observed; what happened is inferred
High temperature (model data)
Day High Monday 18 °C Tuesday 20 °C Wednesday 22 °C Milo's cousin says, "Each of the last three days was warmer, so tomorrow will be the hottest day of the year." Which response is best?
- Agree: three days show the whole year
- Agree: a rising trend has to keep rising each day
- Disagree: the days were getting colder
- Disagree: three days are too few to predict that
Bounce height (model data)
Trial Bounce Note 1 42 cm none 2 41 cm none 3 18 cm hit a book 4 43 cm none Pia's ball bounced 42, 41, 18 and 43 cm. On the 18 cm trial it hit the edge of a book. What should Pia do?
- Stop testing, since the data are ruined
- Average the four trials and leave no note
- Report 18 cm as the result
- Note the cause and redo that trial
Plant height (model data)
Week Height Note 1 3 cm none 2 5 cm none 3 7 cm none 4 4 cm from pot rim 5 11 cm none Ren measured a plant weekly: 3, 5, 7, 4 and 11 cm. Week 4 was measured from the pot's rim, not the soil. Which result is odd?
- Week 1's 3 cm, the smallest
- Week 5's 11 cm, the tallest
- Week 4's 4 cm, measured from the wrong spot
- There is no odd result; plants shrink at times
Classroom temperature (model data)
Reading Temperature Note 1 21 °C none 2 22 °C none 3 22 °C none 4 35 °C in sunlight 5 21 °C none Tala recorded classroom temperatures of 21, 22, 22, 35 and 21 °C. The 35 °C reading was taken with the thermometer in direct sunlight. What should Tala do?
- Retake that reading out of the sunlight
- Say the room heated up to 35 °C that day
- Keep 35 °C, since it was measured
- Record the room as hot, with no number
Ari's seedling was 2 cm on day 2, 4 cm on day 4 and 6 cm on day 6. About how tall will it be on day 8?
- About 8 cm
- About 4 cm
- About 16 cm
- About 6 cm, as on day 6
Ice mass (model data)
Time Mass 0 min 30 g 5 min 24 g 10 min 18 g 15 min 12 g Bo weighed an ice cube on a plate every 5 minutes. When will it be fully melted, if the pattern continues?
- At about 25 minutes
- At 15 minutes, when it was 12 g
- It will not melt, since the mass keeps growing
- The room must be very hot
