Unit review questions
1. Which scientific label fits the specifically described step or feature? Supplied case: Different pressures are measured at two locations.
Need a hint?
  • Look for the described feature: can drive air movement.
  • Compare the given mechanism with the other labels; do not infer unmentioned events.
2. Which scientific label fits the specifically described step or feature? Supplied case: Puddle water changes into vapor.
Need a hint?
  • Look for the described feature: liquid enters gas phase.
  • Compare the given mechanism with the other labels; do not infer unmentioned events.
3. Supplied case 5: first record (°C)=16; second record (°C)=19; third record (°C)=22, using the explicitly named quantities. Mean of three supplied values equals their sum divided by three. What result follows?
Need a hint?
  • Mean of three supplied values equals their sum divided by three.
  • Divide by the number of observations.
4. Which scientific label fits the specifically described step or feature? Supplied case: A specific afternoon thunderstorm.
Need a hint?
  • Look for the described feature: one specified atmospheric event.
  • Compare the given mechanism with the other labels; do not infer unmentioned events.

Use the skills in a new task

Create a four-panel explanation for “Weather, Air and Climate” using one supplied case from each lesson. Include the observation, scientific mechanism or calculation, result and a limitation. You may draw and speak your explanation; all inputs are supplied.

Work on paper or in your own document. Explain the choices you made.

  • Use one supplied case from each of the four lessons.
  • Name the relevant structure, quantity or process in every panel.
  • Show calculations with units or a causal evidence chain.
  • Distinguish source facts from fictional classroom data.
  • State a model limit or a condition that would change the result.
Compare with a model response

Panel 1: A simple surface model has pressure 1010 hPa at A and 1000 hPa at B. What initial tendency fits? Which inference or prediction is best supported? Result: Air tends from A toward B under the simplified pressure-gradient model.. Reasoning: The gradient supports high-to-low tendency; real wind also involves rotation, friction and geometry. Model limitation: only the stated classroom boundary and supplied observations are established; unmeasured real-world performance remains unverified. Panel 2: Water evaporates from a surface and later condenses in a cloud model. What remains conserved? Which inference or prediction is best supported? Result: The water substance changes phase and location rather than being created.. Reasoning: Phase changes and transfers move existing water through the model. Model limitation: only the stated classroom boundary and supplied observations are established; unmeasured real-world performance remains unverified. Panel 3: Supplied case 1: first record (°C)=12; second record (°C)=15; third record (°C)=18, using the explicitly named quantities. Mean of three supplied values equals their sum divided by three. What result follows? Result: 15 °C. Reasoning: Substitute the supplied values: ((12)+(15)+(18))/3 = 15 °C. Add every supplied value. Means do not show the full spread or establish causation. Model limitation: only the stated classroom boundary and supplied observations are established; unmeasured real-world performance remains unverified. Panel 4: A city has one unusually cold Tuesday while its matched 30 year records trend warmer. What is warranted? Which inference or prediction is best supported? Result: The event and long-term trend can both occur.. Reasoning: Weather varies within a distribution; climate concerns patterns over longer periods. Model limitation: only the stated classroom boundary and supplied observations are established; unmeasured real-world performance remains unverified.

A different response can also meet the criteria. Compare the evidence and reasoning, rather than copying the wording.
