STAAR REVIEW - SCIENCE

How are organisms, such as snakes, cacti and coyotes able to survive in harsh desert conditions?

• Over thousands of years these organisms have developed adaptations to survive in arid climates

• These organisms migrate out of the desert during the summer months

• These organisms work together to find sources of food and water

• Snakes, cacti and coyotes are all aquatic species that live in ponds and rivers during the hot day

Which event best describes an example of evaporation?

• Water flows downhill after a storm

• Dark clouds form in the sky

• Rain water oaks into the ground

• Solar energy heats water at the ocean's surface.

Which statement describes how fossil fuels are made?

• Oil from Earth's core slowly rises to the Earth's surface and forms ponds

• Lava within some volcanoes becomes so hot that it transforms into fossil fuels

• Dead and decomposing organisms are exposed to extreme heat and pressure transforms them into fossil fuels

• When mountains form on top of coal, the pressure liquefies the coal creating fossil fuels

A student helped his father prepare soup for dinner. His father asked him to use a wooden spoon to stir the soup as it heated.

Why would the student's father ask him to use a wooden spoon?

• The wooden spoon is able to float in the soup

• the wooden spoon is able to sink in the soup

• the wooden spoon is a good conductor of thermal energy

• The wooden spoon is a good insulator of thermal energy

Which of the following best illustrates the direction of energy flow through the food web above?

• Spider to Grasshopper to Grass

• Hognose snake to toad to grasshopper

• Grass to rabbit to hawk

• mouse to spider to toad

A student places 250 g samples of clay, sand, gravel, and silt in separate flower pots. The pots are set on a wire rack, and dishes are placed beneath the pots so that water can drip through holes and collect. The student then pours 100 mL of water over the sample in each pot. The student measures the time it takes for water to begin dripping from the bottom of each pot.What property of soils is the student most likely examining with this procedure?

• The amount of time it takes different soils to dry

• How well different soils retain water

• How much water is needed to dissolve different soils

• The differences in texture between wet and dry soils

• When Switch 1 is closed and Switches 2 and 3 are open, both bulbs will light. 

• When Switches 1 and 3 are closed and Switch 2 is open, only Bulb Y will light.

• When Switches 2 and 3 are closed and Switch 1 is open, only Bulb X will light.

• When Switches 1 and 2 are closed and Switch 3 is open, neither bulb will light.

the process by which dissolved minerals in the water glue particles of sediment together into one rock.

• fossils

• compaction

• cementation

• weathering

When using a solar-powered calculator, what source of energy is being used to power the calculator?

• Electrical Energy

• Light Energy

• Mechanical Energy

• Sound Energy

What is one difference between weather and climate?

• weather describes conditions near the ground, but climate does not.

• Climate describes energy from the sun, but weather does not.

• weather includes precipitation, but climate does not.

• Climate describes long-term conditions over an entire region, but weather does not.
