STAAR 2.0

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

Some students are feeding a crab in an aquarium. They use tongs to place the food directly in front of the crab. The students look through the side of the aquarium. They notice that the image of the tongs appears to break as the tongs enter the water. Which property of light are the students observing in this situation?

• Light can be refracted and separated into different colors as it moves from air to a different medium.

• Light is refracted as it moves from one medium to another medium.

• Light travels in a straight line and can be reflected off the surface of water

• Light is absorbed by water and reflected off glass.

• travels in straight lines and reflects from the surface of the mirror

• enters the mirror and changes direction when it is refracted by the back of the mirror

• refracts in the glass of the mirror and is spread out all over the room

• travels through air and does not change its direction in air

The picture below shows a cumulonimbus cloud forming over an ocean. Which statement best explains how the sun and the ocean interact to form a cumulonimbus cloud?

• Heat from the sun causes clouds in the area to gather over the ocean and form one large cumulonimbus cloud.

• Heat from the sun warms the ocean, causing water to evaporate. The water vapor then condenses to form a cumulonimbus cloud.

• Light from the sun shines on the ocean, causing water vapor to condense. The water then evaporates to form a cumulonimbus cloud.

• Light from the sun causes ocean water to reflect water vapor into the air and gather over the ocean into a cumulonimbus cloud.

• Energy is transferred from grasshoppers to crickets to frogs to hawks.

• Energy is transferred from cattails to crickets to shrews to hawks.

The leaves of two types of plants that live in different environments are shown in the pictures. The leaves of both plants have different structures. What differences in the structure of the leaves of these plants likely help them survive in their environments?

• The pan-like shape of the giant water lily leaves helps them catch rainwater. The slim shape of the mesquite leaves helps them avoid sunlight

• The broad shape of the giant water lily leaves helps them stay on the water surface. The slim shape of the mesquite leaves helps them prevent water loss.

• The pan-like shape of the giant water lily leaves helps them attract small fish. The slim shape of the mesquite leaves helps them avoid herbivores

• The broad shape of the giant water lily leaves helps them attract aquatic birds. The slim shape of the mesquite leaves helps them attract pollinators.

A family takes a group picture in a park where bluebonnets are blooming. The family notices that some of the blooms are white and others are blue. The color of the blooms is most likely determined by —

• inheritance from parent plants

• the age of the plant

• the types of consumers that eat the plant

• air temperature
