Water, Air, Weather & Climate — Extension · Science 6: Matter, Energy & Earth Systems, Grade 6
How do water, air, and energy processes connect weather with longer-term patterns? What can a matched five-day record tell us about weather, and what requires a different climate record?

What can a matched five-day record tell us about weather, and what requires a different climate record?
Three 35–45-minute sessions: plan and predict; examine or collect evidence; explain, revise, and reflect. Use the complete supplied record when materials, time, access, or safe conditions are unavailable.
Materials
- The full supplied weather table, graph paper, and a calculator if useful.
- Optional safe indoor notes about visible conditions; no identifying home-location details are needed.
- A notebook recording variable, units, time, and method.
Before you begin
Use supplied records during hazardous weather. Do not go outdoors to observe lightning, collect dangerous storm water, or launch objects for measurements. The classroom task does not provide a travel-safety forecast.
Plan a comparable record analysis
All supplied temperature records are noon readings at one fictional shaded position, pressure uses hPa, and rainfall is the previous 24-hour collected depth. Keep their intervals distinct. No sample represents all places or daily maximum temperatures.
Method
- Identify what each column measures and its stated time interval before graphing.
- Plot the noon temperatures against day with labeled °C and a consistent scale. Keep rainfall as a separate measured quantity.
- Calculate mean noon temperature and total recorded rainfall over the five intervals.
- Compare pressure and rain patterns, explaining why their association is not a complete cause or prediction rule.
- Read the separate same-region, same-season illustrative long-term means of 14.0, 14.5, and 15.0 °C across equal multi-year periods. Distinguish that record from the five daily readings.
- Write a bounded report with two pieces of evidence, one uncertainty, and a revision correcting a noon-is-maximum or one-week-is-climate claim.
Supplied illustrative record — use when an actual test is unavailable
Illustrative classroom data authored for analysis, not measurements from a real learner, stream, product, or field study. Actual observations may differ; record them honestly and compare the methods.
| Day | Noon temperature (°C) | Noon pressure (hPa) | Previous 24 h rainfall (mm) |
|---|---|---|---|
| 1 | 20 | 1,014 | 0 |
| 2 | 21 | 1,012 | 0 |
| 3 | 18 | 1,005 | 8 |
| 4 | 17 | 1,006 | 3 |
| 5 | 19 | 1,010 | 0 |
Analyze and explain
- Find the mean noon temperature and total rainfall; preserve the methods.
- Describe a temperature change and a pressure/rain association with a limit.
- Why does this table not establish daily maxima or regional climate?
- What change is shown in the separate matched long-term summaries, and what does their shape alone not prove?
What a strong explanation includes
- Correct 19 °C mean and 11 mm rainfall total.
- Time intervals and units preserved.
- Pattern distinguished from cause or guarantee.
- Weather and climate evidence separated.
- A substantive correction or model limit explained.
Parent / teacher guide: discuss after the investigation
The five noon readings sum to 95 °C across the observations, giving a mean of 19 °C. The recorded previous-24-hour rainfall intervals total 11 mm. Those summaries refer to this fictional position and stated sampling periods; they cannot be relabeled as daily temperature maxima or a complete regional rainfall survey. The zero-rain entries are measured zeros here, whereas a missing entry would need a different label. Temperature falls between days 2 and 4, then rises on day 5. The two rainy entries coincide with lower recorded pressure than the first two days. That pattern is evidence of changing conditions, not proof that pressure alone causes every rain event. Humidity, air masses, movement, and other factors would contribute to a better explanation or forecast. A graph should use separate units and preserve all entries rather than select only the two rainy days. The separate long-term seasonal means rise from 14.0 to 15.0 °C, a 1.0 °C difference across equal multi-year periods. That is a different time-scale record. A cold day can occur within a warmer long-term pattern, and the trend’s shape alone does not establish its cause. A revised report should distinguish observation from prediction, weather from climate, and a local measurement from a broader spatial claim.
Compare this model with the learner’s actual evidence. Different measurements can support a different conclusion; check the reasoning and limitations, not matching wording.
Extend the chapter investigation by evaluating its evidence and proposing a better test.
