NGSS Science Review

Use the first passage on pg 1 of your study guide to answer this question.

The students observed that the smaller ice cubes in Ice Bath 2 melted faster than the larger ice block in Ice Bath 1.

​

Based on the ice bath setup in Figure 1, which statement best explains why several smaller ice cubes melt faster than a larger block of ice?

• Smaller ice cubes have more surface area in contact with the liquid water, so more thermal energy is transferred from the water to the ice.

• Smaller ice cubes have more surface area in contact with the liquid water, so more thermal energy is transferred from the ice to the water.

• A larger ice block has more surface area in contact with the liquid water, so less thermal energy is transferred from the ice to the water.

• A larger ice block has more surface area in contact with the liquid water, so less thermal energy is transferred from the water to the ice.

Use the passage on pg 1 of your study guide to answer the question below.

The students want to collect data on how the average kinetic energy of the liquid water molecules in the ice baths changes during the experiment.

Which statement best describes a change to the ice bath experiment that will help the students collect this data?

• Measure the water height in each ice bath throughout the experiment and compare the initial and final water heights.

• Measure the water volume in each ice bath throughout the experiment and compare the initial and final water volumes.

• Measure the size of each piece of ice in each ice bath throughout the experiment and compare the initial and final sizes of each piece of ice.

• Measure the water temperature in each ice bath throughout the experiment and compare the initial and final water temperatures.

Use the passage on pg 3 of your study guide to answer the question below.

Like some traits in other plants, spider plant traits can change over time through the process of natural selection.

​

Which trait change would most likely affect both the pollination and the probability that future generations of spider plants will survive?

• a change in the number of pups per plant

• a change in the color of the leaves

• a change in the shape of the flowers

• a change in the size of the seeds

Different types of trait selection can take different amounts of time for trait changes to occur.

​

Which change would cause the traits of a spider plant to change the fastest?

• spider plants adapting to different climates in South Africa

• a gardener planting a spider plant in a new garden

• spider plants adapting to light intensity in different locations

• a botanist developing a new type of spider plant

Whales play a very important role in recycling nutrients throughout aquatic systems. Whales often feed on organisms deep below the ocean surface and then release their food waste as they move to shallower depths. This waste contains nutrients, such as nitrogen, phosphorus, and iron, that can be used by other organisms in the ecosystem. This process, known as the "whale pump," is shown in the diagram.

In an ecosystem where the "whale pump" process occurs, which change would most likely increase the amount of nutrients recycled into shallower ocean depths?

• introducing more fish into the ecosystem to increase the fish population

• improving whaling efforts to decrease the whale population

• removing phytoplankton from shallow ocean depths to decrease the amount of phytoplankton

• making whales a protected species to increase the whale population
