Tutor lesson-prep guides · Primary General Studies

Every student has heard of signal number eight, yet few can name nine and ten, or say what separates a black rainstorm from a red one. This lesson turns recognition into reading the warning and acting on it.

Objectives — Students can: (1) name the five tropical cyclone levels (1, 3, 8, 9, 10) and explain why signal 8 has four directions; (2) use hourly rainfall to tell amber, red and black rainstorms apart; (3) give three safe actions under thunderstorm and landslide warnings; (4) explain that school closure follows the Education Bureau announcement rather than personal judgement.

01 Prerequisites (3-minute check)

If any of these fails, fix it before the lesson starts.

Skill	Quick check	Pass mark
Local geography	What surrounds Hong Kong	Sea to the south, so typhoons arrive from the South China Sea
Comparing numbers	Which is larger, 70 or 50	70, so black is heavier than red
Directions	How many directions does signal 8 have	Four: northeast, northwest, southeast, southwest
Reliable sources	Who issues weather warnings	The Hong Kong Observatory

02 Lesson flow (45 minutes)

Time	Stage	Tutor does	Student does
0–7 min	Starter: last storm	Ask what the student did during the last typhoon	Gives one concrete memory
7–16 min	Five cyclone levels	Write 1, 3, 8, 9, 10 on the board and explain each; cover the four directions of 8	Orders the eight signals and names the strongest
16–25 min	Three rainstorm levels	Compare 30, 50 and 70 mm and name amber, red, black	Says black is the heaviest
25–34 min	Thunderstorm and landslide	Cover indoor and outdoor rules and slope risk	Gives one “never do this” per warning
34–42 min	Closure and preparation	Education Bureau announcements, before and after signal 8, home preparation	Gives three steps
42–45 min	Exit check	Three quick oral questions	Answers independently

03 Teaching script (read it out)

Scene 1: Signals are levels, not “how many typhoons”

Students say “number eight” and assume it is the maximum. Correct it with a ladder: 1 is standby, 3 means winds strengthening, 8 means gale or storm force winds of 63 to 117 kilometres per hour, 9 means winds increasing, and 10 means hurricane force at 118 kilometres per hour or above.
Signal 8 then splits into four directions, because where the wind comes from decides which windows are dangerous. Once that is clear, the four directions stop looking arbitrary.

Student does: orders all eight signals from weakest to strongest and points to 10 as the strongest.

Scene 2: Rainstorms are graded by rainfall, not by feeling

Students say “very heavy rain”, so amber and black sound the same. Give three numbers and require comparison sentences: amber above 30 millimetres an hour, red above 50, black above 70.
Add a felt anchor: under a black rainstorm a road can flood to ankle depth in a quarter of an hour, so the rule is stay somewhere safe and never wade. Water above the calf can already sweep a child off their feet, and that is the line students remember.

Student does: orders the three rainfall figures and matches the colours.

Scene 3: Response splits into indoor, outdoor and slope situations

Asked about safety, students produce one answer: stay home. Split the situations so the answers become usable: indoors, close windows, stay away from glass, do not touch metal frames; outdoors, get into a building, avoid trees and power lines, never watch waves from the shore; under a landslide warning, keep away from slopes and retaining walls, and leave at once if the ground cracks or water turns muddy.
Finish on closure: it follows the Education Bureau announcement, and the announcement still matters after signal 8 is lowered.

Student says: one “never do this” for each of the three situations.

04 Question types and worked steps

Type	Example	Steps	Answer
Reading a signal	Signal 9 has been issued – what does it mean	Check the level, the wind speed, then the action	Winds increasing; stay indoors away from windows
Comparing rainfall	Red or black, which is heavier	Compare 50 with 70	Black, above 70 millimetres an hour
Judging danger	Going to the shore under signal 8	Name the danger, then the correct action	Waves and debris; stay indoors
Ordering a response	Black rain and a flooded route home	Find shelter, call family, wait for news	Do not wade, go up a level, phone home

Sanity check (teach this): Reasonableness checks: the order must run 1, 3, 8, 9, 10 and never put 9 above 10; signal 8 covers 63 to 117 kilometres per hour and signal 10 is 118 or above, and the figures must not reverse; the three rainstorm levels must rise 30, 50, 70; every response answer needs one concrete “do not”; closure always follows the Education Bureau, never personal judgement.

05 Independent practice (3 questions)

Question	Answer	What to watch
4 signal questions	1, 3, 8 and 10	Checks that an action is given, not just a name
3 rainfall comparisons	Amber with red, red with black, black with amber	Checks the 30, 50, 70 figures are used
2 scenario responses	Black rain on the street, signal 8 at home	Checks concrete actions rather than “be careful”

06 Common mistakes and what to say

Mistake	Student writes	Say this
Believing 8 is the maximum	“After eight it is over”	“Nine and ten come after eight. Ten is hurricane force, 118 kilometres per hour or more.”
Treating amber rain as harmless	“We still go out in amber”	“Amber already means 30 millimetres an hour; drains struggle, so stay away from slopes and low ground.”
Wave watching under signal 8	“I want to see how big the waves are”	“The shore is the most dangerous place under eight; waves and debris sweep people away. Stay in and away from windows.”
Deciding on school closure alone	“It is windy so I will not go”	“Closure follows the Education Bureau announcement. Read the official notice, do not guess.”

07 Homework (paper, section and question numbers)

P5 general studies paper (with answers) — Do the weather and hazard questions
Primary General Studies chapter index — All chapters in the subject
Redo this chapter — Redo the three scenarios, one “never do this” each

08 Exit check (last 5 minutes)

Question	Answer	Decision
What follows signal 8	Signals 9 and 10	Answering 8 only means going back to the second stage
Black rain rainfall	Above 70 millimetres an hour	A wrong figure means going back to the third stage
Shore under signal 8	Never; waves and debris	Answering yes means going back to the fourth stage
Who announces closure	The Education Bureau	Answering “yourself” means going back to the fifth stage

09 Tutor FAQ

Must students memorise every wind speed?

Only two boundaries: 63 to 117 for signal 8 and 118 or above for signal 10. The rest is level and response; extra numbers crowd them out at P5.

What about students in village or rooftop housing?

Add reinforcing windows, tying down balcony items, and preparing a torch and radio. Rooftop structures should plan to stay with relatives, because hurricane winds exceed what temporary structures are built for.

Should climate change be raised?

One line about more extreme rainfall is enough; the main thread stays reading warnings and responding correctly.
