Darllen ap tywydd: Reading a Welsh weather app for a beach clean

You have a worksheet and a stimulus sheet called Ap tywydd: Aberystwyth. Your class is going to clean the beach in Aberystwyth. Today you read an invented 5-day Welsh weather app to choose the best day and the best 2 hours, do the calculations, and decide whether a scary post about snow is true. All the Welsh you need is on the stimulus sheet, with English in italics.

While the register is called: write your name (Enw), class (Dosbarth) and date (Dyddiad) on your worksheet, then read section 4, Geirfa / Vocabulary, on the stimulus sheet.

Starter question: Look at Sgrin 1. Which day is heulog (sunny), and what is its highest temperature?

DCF: Data and computational thinking → Data and information literacy No computers needed · calculators optional

Supply teacher script (no subject knowledge needed)

Hand out: one worksheet per pupil and one stimulus sheet (Ap tywydd: Aberystwyth) between two. No computers are needed. Calculators are optional. You need no Welsh: every Welsh word pupils need is translated in italics on the stimulus sheet, and the answers below are given in English with the Welsh beside them. The app screens, the post and every figure are invented.

Say aloud: “Name, class and date at the top: Enw, Dosbarth, Dyddiad. While I take the register, read section 4 on the stimulus sheet, the vocabulary table. Then find the sunny day on Screen 1. Sunny is heulog.”

Starter answer: Dydd Iau (Thursday) is heulog, with a highest temperature (Uchaf) of 12°C. The days on Screen 1 run Dydd Llun (Monday), Dydd Mawrth (Tuesday), Dydd Mercher (Wednesday), Dydd Iau (Thursday), Dydd Gwener (Friday).

Slide 2 of 7 · Today’s brief and key words · Welsh · Year 7

3 minutes

Your brief: read the data, calculate, choose a day, then test the post

You will learn 8 weather words, read 5 answers off the app screens, find each day’s temperature range and the mean highest temperature, test every day against the teacher’s 3 rules for the beach clean, judge a 3-week-old social media post against the Met Office forecast, and write 3 Welsh sentences about Thursday.

Uchaf / Isaf

Uchaf is the highest temperature in the day. Isaf is the lowest, usually at night or early morning. Range = Uchaf minus Isaf.

Siawns o law

Chance of rain, as a percentage. 10% means rain is unlikely; 90% means it almost certainly will rain.

Reliable source

Information you can trust because you know who made it, when, and it uses calm facts and numbers rather than capital letters and “Share!”.

Slide 3 of 7 · Cam 1 and Cam 2: vocabulary, then reading the app · Welsh · Year 7

12 minutes

Cam 1 & Cam 2: 8 weather words, then 5 answers from the screens

Cam 1 (5 min): write the Welsh word for each of the 8 English words, using section 4 of the stimulus sheet. Then cover the sheet and test your partner. The first one is on the board. Cam 2 (7 min): answer (a) to (e) with a number or a day, using Sgrin 1 and Sgrin 2. Give the unit (°C, %, mya).

sunny	cloudy	windy	foggy	rain	snow	temperature	colder
heulog

Cam 2 (e) is a trap: “warmer than 10°C” means more than 10, not 10 exactly.

Slide 4 of 7 · Cam 3 and Cam 4: calculating, then which day? · Welsh · Year 7

14 minutes

Cam 3 & Cam 4: ranges and the mean, then test the 3 rules on every day

Cam 3 (7 min): (a) range for each day = Uchaf − Isaf; careful with Friday, where Isaf is −1. Monday is on the board: copy it. (b) Mean of the 5 highest temperatures: add them, divide by 5, show working. (c) Thursday: how many degrees does it rise from 09:00 to 13:00, and when does the chance of rain start to go up? Cam 4 (7 min): tick or cross each rule for each day, write the Welsh sentence in the frame, then choose the best 2 hours from Sgrin 2.

Dydd Llun	Dydd Mawrth	Dydd Mercher	Dydd Iau	Dydd Gwener
9 − 4 = 5

The 3 rules: chance of rain 20% or less · wind less than 20 mya · highest temperature 10°C or more. Write the number next to each tick or cross.

Cam 3 and Cam 4 on your worksheet · 14 minutes Test every rule on every day before you decide

Supply teacher script (no subject knowledge needed)

Say aloud: “Cam 3: Monday’s range is 9 take away 4, which is 5. Copy it and do the other 4. Friday’s lowest is minus 1, so count 1 degree up to zero and then 9 more. Then the mean and question (c). After 7 minutes, Cam 4: tick or cross each rule for each day and write the number beside it. Finish the Welsh sentence in the frame and pick the best 2 hours from Screen 2.”

Quick check, Cam 3: (a) ranges 5, 7, 7, 10, 10 (Friday: 9 − (−1) = 10, not 8). (b) 9 + 10 + 8 + 12 + 9 = 48, and 48 ÷ 5 = 9.6°C. (c) 12 − 6 = 6 degrees; the chance of rain starts to go up after 12:00 (5% at 12:00, then 10%, 20%, 30%).

Quick check, Cam 4: Glaw: Llun ✗ 90%, Mawrth ✗ 40%, Mercher ✗ 30%, Iau ✓ 10%, Gwener ✓ 10%. Gwynt: Llun ✗ 25, Mawrth ✓ 15, Mercher ✗ 35, Iau ✓ 10, Gwener ✓ 5. Tymheredd: Llun ✗ 9, Mawrth ✓ 10, Mercher ✗ 8, Iau ✓ 12, Gwener ✗ 9. Only dydd Iau passes all 3. Sentence: “Y diwrnod gorau ydy dydd Iau achos bydd hi’n heulog.” (The best day is Thursday because it will be sunny.) Best 2 hours: 11:00 to 13:00, only 5% chance of rain and 10 to 12°C. Friday looks good but fails on temperature.

Slide 5 of 7 · Cam 5 and Cam 6: is the post true? then Thursday’s forecast · Welsh · Year 7

12 minutes

Cam 5 & Cam 6: judge the snow post, then write 3 Welsh sentences about Thursday

Cam 5 (7 min): your friend shared the snow post in section 3. Fill the table comparing the app and the post, in English. The first row is on the board: copy it. Then: should you share the post? Give 2 reasons from the table. Does 1,900 shares make it more likely to be true? Cam 6 (5 min): write 3 sentences in Welsh about Thursday using Bydd hi’n ..., a number, and cynhesach na (warmer than) or oerach na (colder than).

Question	Ap tywydd	Neges (the post)
Who made it? Are they a real weather service?	The Met Office, the UK’s national weather service	An unknown page, no link and no weather service named

Model sentence: Bydd hi’n heulog ddydd Iau. (It will be sunny on Thursday.) After a number use gradd: Bydd hi’n 12 gradd.

Cam 5 and Cam 6 on your worksheet · 12 minutes Who made it, when, what does it say, how does it talk

Supply teacher script (no subject knowledge needed)

Say aloud: “Cam 5: row 1 is on the board. The app is from the Met Office; the post is from a page nobody can check. Fill in the other 3 rows: when, what it says about Friday, and the kind of language. Then decide: share or not, with 2 reasons. After 7 minutes, Cam 6: 3 Welsh sentences about Thursday. Start each with Bydd hi’n, put a number in one, and compare Thursday with another day in one.”

Quick check, Cam 5: When: app updated today at 06:00; post 3 weeks ago, so it cannot be about this Friday. Friday: app says foggy (niwlog), 9°C high, −1°C low, 10% chance of rain; post says heavy snow and schools closed. Language: app is calm, numbers and facts; post uses capital letters, lots of exclamation marks, “100% Cywir” (100% correct) and asks you to share. Decision: do not share. It is 3 weeks old and names no source, while the app is from the Met Office and updated this morning. 1,900 shares does not make it true: people share scary posts without checking, so false posts can spread fastest.

Walk the room, Cam 6: a secure answer is “Bydd hi’n heulog ddydd Iau. Bydd hi’n 12 gradd am un o’r gloch. Bydd dydd Iau yn gynhesach na dydd Mercher.” (It will be sunny on Thursday. It will be 12 degrees at one o’clock. Thursday will be warmer than Wednesday.) Accept any true figures from the screens. “yn gynhesach” with a g is correct Welsh; do not mark it wrong.

Slide 6 of 7 · Self and partner check · Welsh · Year 7

3 minutes

Swap with your partner and check against the success criteria

Tick each success criterion your partner’s work meets. Then correct 1 thing: Friday’s range (it is 10, not 8), a tick that should be a cross in Cam 4, or a Welsh sentence with no number or comparison.

I can read temperatures, percentages and wind speeds from a table in Welsh.
I can calculate a range, including with a negative number, and a mean.
I can use data to test rules and make a decision.
I can judge whether a source is reliable by checking who made it, when, and the language it uses.
I can write simple weather sentences in Welsh with a number and a comparison.

Round the room, then quick-check answers before handing in

Everyone says 1 Welsh weather word and its English meaning, nobody repeats one. Then check these answers.

Question	Correct answer
Which day is the beach clean, and at what time?	Dydd Iau (Thursday), 11:00 to 13:00. The only day that passes all 3 rules: 10% rain, 10 mya wind, 12°C.
What is Friday’s temperature range, and the mean highest temperature?	Friday: 9 − (−1) = 10. Mean: 48 ÷ 5 = 9.6°C.
Give 2 reasons the snow post is not reliable.	It is 3 weeks old, names no weather service, and shouts in capitals with “Share!”. The Met Office app says foggy, not snow. 1,900 shares proves nothing.
