6.ESS2.5 - Weather data and predictions

Analyze and interpret data from weather conditions, weather maps, satellites, and radar to predict probable local weather patterns and conditions.

Multiple Choice

You notice a very large drop in air pressure during the course of a few hours on a summer day. What weather conditions will likely occur at the student's location in the next 6 to 8 hours?

• rainy and windy

• partly cloud and breezy

• sunny and calm

6.ESS2.6 - Air Masses

Explain how relationships between the movement and interactions of air masses, high and low pressure systems, and frontal boundaries result in the weather conditions and severe storms.

Multiple Choice

When a cold fronts approaches and covers an area, which changes usually occur?

• Both air pressure and temperature increase

• Both air pressure and temperaure decrease

• Air pressure decreases and temperature increases

6.ESS2.3 - Climate and heat transfer

Construct an explanation for how atmospheric flow, geographic features, and ocean currents affect the climate of a region through heat transfer.

Multiple Choice

The Gulf Stream is a warm ocean current that flows along the east coast of Florida. How does the Gulf Stream affect the climate of Florida?

• It keeps the east coast of Florida cooler than landlocked southeastern states throughout the year.

• It keeps the east coast of Florida warmer than landlocked southeastern states throughout the year.

• It keeps the east coast of Florida warmer in winter and cooler in summer than landlocked southeastern states.

6.ESS2.4 - Impact of humans and other organisms on the hydrologic cycle

Apply scientific principles to design a method to analyze and interpret the impact of humans and other organisms on the hydrologic cycle.

Multiple Choice

An article states that industrial activities release large amounts of water vapor into the atmosphere. How could the industries affect the hydrological cycle?

• by increasing condensation

• by decreasing evaporation

• by increasing transpiration

6.ESS2.1 - Oceanic convection currents

Gather evidence to justify that oceanic convection currents are caused by the sun's transfer of heat energy and differences in salt concentration leading to global water movement.

Multiple Choice

Which is a major factor that causes ocean currents?

• unequal heating of the oceans

• high wind speeds caused by seasonal storms

• amount of aquatic vegetation on the ocean floor

6.ESS2.2 - Convection Patterns

Diagram convection patterns that flow due to the uneven heating of the earth

Multiple Choice

What is the Coriolis effect?

• a change in energy absorption from sunlight, causing predictable global wind patterns

• a pattern of curvature as a result of Earth’s rotation, causing predictable global wind patterns

• the exchange of salt content with rivers and the ocean, causing predictable ocean currents

6.ESS3.2 - Tech and Renewable/alternative energy

Investigate and compare existing and developing technologies that will utilize renewable and alternate energy sources.

Multiple Choice

Which advancement in energy-producing technology is an example of improving a nonrenewable resource?

• reducing sulfur in diesel gasoline

• generating electricity from ocean tides

• developing higher efficiency solar panels

6.ESS3.1 - Renewable and nonrenewable resources

Differentiate between renewable and nonrenewable resources by asking questions about their availability and sustainability.

Multiple Choice

Fossil fuels contribute to about 85% of the total energy produced in the world. What is a direct environmental consequence of the extensive use of fossil fuels?

• increase in the amount of precipitation

• decrease in the amount of greenhouse gas emissions

• decrease in natural resources

6.PS3.4 - Thermal energy moves through objects

Conduct an investigation to demonstrate the way that heat (thermal energy) moves among objects through radiation, conduction, or convection.

Multiple Choice

Carbon dioxide is a solid at temperatures below -78.5°C. A sample of solid carbon dioxide is placed on a table near a window inside a classroom. The temperature in the classroom is 22°C. Students observe that the solid changes directly into a gas within a few minutes.

• The air warms the sample by conduction, and sunlight warms the sample by radiation.

• The air warms the sample by radiation, and sunlight warms the sample by convection.

• The air warms the sample by radiation, and sunlight warms the sample by conduction.

6.ETS1.2 - Solutions that impact energy transfer

Design and test different solutions that impact energy transfer.

Multiple Choice

A student designs two different insulated bottles using household items to keep drinks warm. Each bottle is filled with 300 mL of water at 70°C. The diagram shows the different designs, and the table shows the starting and final temperatures of the water after 30 minutes.

The effect of which factor in the design can be determined by analyzing the results?

• amount of water

• presence of a lid

• thickness of the rubber sheet

6.PS3.2 - Transformation between potential and kinetic energy

Construct a scientific explanation of the transformation between potential and kinetic energy.

Multiple Choice
