Practice lab
Thirty short challenges.
One connected atmosphere.
Each challenge lives inside its lesson so you can review the notes before trying again. Choice, matching, and sequence activities all give immediate feedback.
Unit 1
Reading the Atmosphere
Day 1Which statement describes climate?choiceDay 2Match each atmospheric component to its best description.matchDay 3Arrange the layers from Earth's surface upward.sequenceDay 4Which observation is direct evidence that a low-pressure system may be approaching?choiceDay 5A profile shows temperature decreasing, then increasing with altitude. What does the turning point most likely mark?choice
Unit 2
Water and Energy
Day 6Place one possible pathway in a logical order.sequenceDay 7Match each phase change to its energy direction.matchDay 8Which change most directly raises relative humidity if water vapor stays constant?choiceDay 9Match the cloud to the strongest clue.matchDay 10Which addition most improves a basic water-cycle diagram as an explanatory model?choice
Unit 3
Air on the Move
Day 11Order the events in an atmospheric convection current.sequenceDay 12At noon the land is much warmer than the ocean. Which near-surface wind is most likely?choiceDay 13What is the best description of the Coriolis effect?choiceDay 14Match each belt or zone to its location or behavior.matchDay 15A deep jet-stream trough moves over the eastern United States. Which change is most plausible?choiceDay 16Arrange the causal chain from energy source to large-scale pattern.sequence
Unit 4
Forecast Lab
Day 17Match each air mass to its core properties.matchDay 18Match the front to the typical clue.matchDay 19A boundary has red semicircles and blue triangles on opposite sides. What is it?choiceDay 20Which pattern best describes a Northern Hemisphere surface low?choiceDay 21What do very closely spaced isobars most strongly indicate?choiceDay 22Match the tool to its strongest use.matchDay 23Pressure is falling, a cold front is approaching, and radar shows a line of showers moving east. What is the best forecast?choice
Unit 5
Climate and Safety
Day 24Which evidence is most appropriate for describing a city's climate?choiceDay 25Arrange the simplified greenhouse-energy pathway.sequenceDay 26Wildfire smoke raises fine-particle pollution. Which public information is most directly relevant?choiceDay 27Match the hazard to the safer response.matchDay 28A hurricane weakens after landfall but moves slowly across central North Carolina. Which threat may increase?choiceDay 29Which message is most useful?choiceDay 30Which chain best connects the whole unit?choice
