Science and Natural Forces: Bölüm 1–2 Kavram ve Kanıt

Read the original science report: A school team designs a soil-moisture sensor, tests it for six weeks and reduces unnecessary watering.

1. A The soil-moisture sensor is only observed and is never designed by the school team.
2. B The designed sensor and measured reduction together describe a scientific achievement.
3. C The six-week test increases unnecessary watering and produces no measurable result.
4. D The six-week project includes neither a designed sensor nor a measured watering result.

Read the original report or safety card: The ground shakes suddenly, and several light objects fall from shelves.

1. A Sudden shaking in the classroom describes slow soil movement down a hillside.
2. B The shelf objects fall before any sudden ground shaking begins.
3. C The sudden movement affects only the shelf objects and not the ground.
4. D Sudden ground shaking identifies an earthquake in the classroom text.

Read the original science report: Dr Kaya compares samples from three valleys and identifies a new local plant species.

1. A Identifying the species is the achievement, and Dr Kaya is the named researcher.
2. B The phrase “three valleys” names the researcher, while Dr Kaya names the study area.
3. C Dr Kaya is the newly identified plant species rather than the researcher.
4. D Comparing the valley samples produces no discovery of a local species.

Read the original report or safety card: After heavy rain, the river moves beyond its banks and water covers two nearby streets.

1. A Overflowing river water that covers streets identifies a flood.
2. B Heavy rain and water over the streets identify a long rainless period.
3. C The river overflows, but its water never reaches the two nearby streets.
4. D The heavy rain causes no river overflow and leaves both streets uncovered.

Read the original science report: Students create a low-cost reader that speaks exhibit names for visitors with visual impairments.

1. A Spoken exhibit information gives the invention no useful result for visitors at the exhibit.
2. B The accessibility benefit clearly explains why the invention is useful.
3. C The invention is useful only because it is expensive, not because it speaks names.
4. D The low-cost reader hides exhibit names from visitors with visual impairments.

Read the original report or safety card: The region receives very little rain for many months, and reservoir levels continue to fall.

1. A Reservoir levels rise because the region receives heavy rain for many months.
2. B Months of little rain leave the reservoir completely full.
3. C The long lack of rain describes a sudden event with overflowing water.
4. D A long lack of rain and falling reservoirs identify drought conditions.

Read the original science report: A paragraph focuses on a reusable filter and says that its first classroom test was in May.

1. A May is a supporting time detail, while the filter project remains the central achievement.
2. B Because the test happened in May, the reusable filter was designed only for that month.
3. C The May classroom-test date is the main idea, while the reusable filter is secondary.
4. D The month of May is the invention, while the reusable filter is only a date.

Read the original report or safety card: Wet soil and rocks move down a steep hillside and block a rural road.

1. A The blocked road causes the soil and rocks to begin moving down the hillside.
2. B Soil and rocks moving downhill identify a landslide, while the blocked road is an effect.
3. C The wet rocks move uphill and leave the rural road completely open.
4. D The wet soil remains fixed on the hillside while the rural road stays clear.

Read the original science report: The card says, “Team Poyraz presented its solar oven model at the school fair.”

1. A The solar oven answers “who,” and Team Poyraz answers “what”.
2. B The sentence names who presented the model but gives no information about what was presented.
3. C Team Poyraz answers “who,” and the solar oven model answers “what”.
4. D The school fair presented Team Poyraz, while no solar oven model appeared.

Read the original report or safety card: The report describes very strong winds, dark clouds and damaged branches.

1. A Dark clouds and damaged branches show that there is no strong wind.
2. B The report mentions strong winds but gives no evidence that they affected anything.
3. C Strong winds and damaged branches are clear evidence of a storm.
4. D The damaged branches cause the strong winds rather than showing their effect.
