Keesha did an experiment to study the rate of photosynthesis in the water plant Elodea. She placed a piece of Elodea in a beaker of water and set the beaker 10 centimeters (cm) from a light source. Keesha counted the bubbles released from the plant every minute for five minutes (min). She repeated the process two more times. First, she moved the light to 20 cm from the beaker, and then she moved the light to 30 cm from the beaker. Keesha’s setup and data are shown below. What is the outcome variable (dependent variable) in this experiment?

• the number of bubbles produced

• the type of plant placed in the beaker

• the distance of the light source from the plant

• the amount of time the bubbles were counted

Lori is learning about two parts of the rock cycle: weathering and erosion. She needs to explain how weathering and erosion are different. Which of the following correctly describes the difference between weathering and erosion?

• Weathering is the movement of rocks by wind; erosion is the movement of rocks by water.

• Weathering is the formation of rocks from lava; erosion is the weathered materials from an area.

• Weathering is the breaking down of rocks; erosion is the movement of weathered materials.

• Weathering is when rocks change from one type of rock to another; erosion is when rocks are broken down.

Many places, like the Grand Canyon, are the result of a combination of processes that continue to shape Earth, like the water cycle and the rock cycle. How does the water cycle influence the rock cycle in an area like the Grand Canyon?

• Large amounts of flowing water increase the rate of weathering and erosion.

• Too much rain soaking into the ground slows the rate of new rock formation.

• Sudden evaporation of water removes moisture from rock layers in the canyon walls.

• Decreased rainfall makes the rocks hard and brittle, so that they crumble into pebbles.

A force of 5 N is required to increase the speed of a box from a rate of 1.0 m/s to 3.0 m/s within 5 s along a level surface. What change would most likely require additional force to produce the same results? (SC.6.P.13.3)

• reduce the mass of the box

• increase the mass of the box

• make the surfaces of the box smooth

• make the surface of the floor smooth
