PSSA Questions 6 th Grade
Water Cycle Which statement correctly describes a water cycle process? A.Evaporation can occur when the water gains energy from the Sun and changes into water vapor. B.Condensation can occur when liquid water molecules in clouds lose energy and fall to Earth. C.Transpiration can occur when atmospheric water vapor gains energy and moves higher in the atmosphere. D.Precipitation can occur when atmospheric water vapor loses energy and forms liquid water droplets.

Scientific Inquiry A scientist wonders if some colors of paint fade more quickly than others. What would be the best way to find out? A.Observe different colors of paint on buildings to see which have faded. B.Paint wooden squares different colors and observe them over time. C.Ask a group of people with different colored houses if their paint has faded. D.Mix different colors of paint together and see which color is the strongest.
Earth’s Atmosphere What danger is posed to humans by the ozone layer? A.The climate will get warmer. B.Exposure to radiation will increase. C.Wildlife will increase in lakes and reservoirs. D.Sea levels will fall.

Fossils A group of scientists excavates an area in southern Pennsylvania. About 10 meters down, they discover fossils of ancient marine mammals. What can the scientists conclude from this finding? A.This area of Pennsylvania was hit by a large tidal wave at one point. B.Undersea terrain has moved beneath the crust from the ocean to Pennsylvania. C.Ancient marine mammals had the ability to move about on land from the oceans to Pennsylvania. D.Parts of Pennsylvania were once underwater.
Solar System What is the difference between a moon and a planet? A.A moon does not have a rotation, a planet does. B.A moon does not directly orbit the Sun, a planet does. C.A planet is large, a moon is small. D.A planet is made of gas, a moon is made of rock.
Scientific Method Which of the following can result after a hypothesis has been tested many times, producing the same result? A.A variable B.A theory C.A control D.A graph
Scientific Method A food worker hypothesizes that the colder the refrigerator is, the longer milk and other perishable foods will last without spoiling.
