Students design an experiment to determine how much force is needed to move bricks with different masses slowly across a platform. Which procedure should student include in their design?
conduct 5 trials, using a different spring scale to pull each brick
conduct 5 trials, pulling each brick in the same way for each trial
conduct 5 trials, using a different platform for each trial
conduct 5 trials, pulling a different side of brick each time
Our teacher has an aquarium in which fish and aquatic plants are growing. How is carbon dioxide directly involved in the survival of organisms in the aquarium?
The plants release carbon dioxide into the water to control the water temperature.
The plants need carbon dioxide to make sugar.
Both the plants and the fish need carbon dioxide to make their own nutrients.
The fish must absorb carbon dioxide through their gills for energy.
Which statement should Mia use to best describe the processes of weathering and erosion?
Weathering and erosion are directly responsible for depositing loose sediments on the bottom of the ocean, forming layers of sediment.
Weathering and erosion are directly responsible for the breakdown of any type of rock into smaller particles and the carrying away of the loose sediments.
Weathering and erosion are directly responsible for the transportation, deposition, and compaction of loose sediments on the seafloor.
Weathering and erosion are directly responsible for the amount of water in a river that transports sediments to the sea.
Which of these describes one or more living organisms that depend on another living organism to survive?
Bacteria living in the mouth of a horse
Ivy plants growing up a fence to reach sunlight
Mold living on a hard, rocky surface
A fish releasing carbon dioxide into the pond water

Design a project to compare the effects of physical changes (such as temperature and pressure) on different states of matter.
Heat and cool water, ice, and steam to observe changes in state and record temperatures at which these changes occur.
Freeze and melt different metals to see which one has the highest melting point.
Apply pressure to various solids to determine their hardness.
Observe the color changes in substances when heated without measuring temperature.

The picture shows an athlete hitting a ball with a tennis racquet. What is the athlete demonstrating in the picture?
Doing work by pushing the ball and changing its motion and position
Changing the position but not the motion of the ball
Doing work by pulling the racquet and changing the ball's position but not its motion
Changing the position and motion of the ball without doing any work
Group 1 is performing an investigation to measure how much liquid water is produced from a 10L sample of snow. What must occur in order for the students to perform this investigation?
The physical state of the sample must remain the same.
The temperature of the sample must change.
The sample must be kept in a freezer.
The investigation must be performed outside.

A beaker with 115 mL of solution has a temperature of 21o C. The solution contains 5g of salt and 115 mL of water. Alex added two ice cubes to the solution and stirred the solution with a stirring rod. Which properties of the solution changed as the ice cubes melted?
the color and physical state of the solution
the volume, temperature, and mass of the salt in the solution
the physical state and temperature of the solution
the temperature, mass, and volume of the solution
Aquatic plants have adaptations that help them live in water. For example, the structures needed for making food are located on the tops of floating plant leaves. This adaptation helps the plants __
avoid predators
stay anchored
absorb sunlight
capture fish
