Not recorded. Getting it wrong is fine. Some numbers in the sources are not needed

1 · A night of heavy rain [science: weather]
Source 1
On an evening when a typhoon was coming close, a (made-up) town measured the rain in each hour. The lowest air pressure that day was 972 hPa. On this sheet, 30 mm or more of rain in one hour is called "very heavy rain".
Source 2 — how deep the rain collected in a rain gauge in each hour. The numbers are made up.
1In which hour did the most rain fall, and how many mm was it?
2If the six hours of rain were "evened out" so that every hour had the same amount, how many mm would that be per hour?
Evening out = add everything, then divide by the number of hours. The same idea as Sunday's "points per game".
3Someone says: "Evened out, it is less than 30 mm an hour, so there was not a single hour of very heavy rain." Is that right? Explain with numbers from the graph.

2 · Water on a river bend [science: running water]
Source 1
The day after the heavy rain, leaves were floated on the outside and the inside of a river bend, and the distance and time were measured (made up). The water was 18 °C.

outside of the bend

Source 2 — how far the leaves went (made up)
4How many metres per second did the water move on the outside, and on the inside?
Draw a double number line first, then write the calculation. Dividing by a decimal is still "per one".
5How many times as fast is the outside as the inside?
6After heavy rain, which bank is more easily worn away, the outside or the inside? Give a reason using your numbers from questions 4 and 5.

3 · What seeds need to sprout [science: germination]

Bean seeds were sown in four bags, and the sprouts were counted 7 days later (a made-up experiment).

7Which bag had the most sprouts?
8For A and B, work out "sprouted ÷ sown" as a decimal, and say which is larger.
The same calculation as a batting average (hits ÷ at-bats). You may also write fractions, simplify, and compare over a common denominator.
9"More seeds sprouted in A, so seeds need light to sprout." Is that right? Explain with numbers from the table.

4 · Two fishing boats [social studies: fishing]

One day's log for two fishing boats from a (made-up) harbour.

10How many kg of fish did each boat catch per litre of fuel?
When you divide by a decimal, multiplying both numbers by 10 gives the same answer.
11How many kg of fish did each boat catch per hour?
12"Boat B fished better." Can you say that? Use your answers to questions 10 and 11 to give your view.
