Weather is the science topic every student has direct evidence for. They walked through it on the way in.
That makes the everyday half of this vocabulary easy, and it makes the other half worth teaching: the words for measuring weather, and the words for weather that most children have only seen on a screen.
What the grid size gives you
The 8x8 and 10x10 stay with what is outside most days: RAIN, SNOW,
WIND, CLOUD, FOG, MIST, FROST, ICE, SUNNY, STORM, HAIL,
SLEET, BREEZE, GUST.
The 12x12 and 14x14 add two groups that a lesson needs. The severe weather:
TORNADO, HURRICANE, BLIZZARD, CYCLONE, MONSOON, DROUGHT, FLOOD.
And the instruments: BAROMETER, THERMOMETER, RADAR, FORECAST,
PRESSURE, HUMID, ATMOSPHERE, JETSTREAM.
Grid size selects on word length, not on category, so the severe weather words
are as likely on a small grid as a large one. Only HURRICANE and THERMOMETER
are long enough to need a 10x10 or above.
The distinction worth five minutes
CLIMATE is on the larger grids, and students conflate it with weather
well past elementary school.
Weather is today. Climate is the pattern over decades. The usual way to make it land: weather is what you are wearing, climate is what is in your closet.
Having both words on one sheet gives you an excuse to say that once, which is about all it takes.
The instruments are the interesting part
Most weather units spend their time on what the weather is. The better question for a fourth grader is how anyone knows what it will be tomorrow.
BAROMETER is the one worth stopping on. It measures air pressure, and falling
pressure means a storm is on the way, which is why old barometers had “stormy”
written on the dial. That is a real prediction from a simple instrument, and it beat the first
weather satellite by three hundred years.
RADAR and FORECAST follow naturally from there.
Read the sky for a week
The activity that outlives the sheet.
After the puzzle, put five of the words on the board: CLOUDY, SUNNY,
OVERCAST, DRIZZLE, BREEZE. Each morning for a week, a different student
picks the one that fits and says why.
It takes ninety seconds a day, it uses vocabulary they had to hunt for once, and by Friday the class is arguing about whether overcast counts as cloudy, which is a real distinction they arrived at themselves.
Which size
The 12x12 or 14x14 for a unit. The everyday words are short and crowd out the long ones on the smaller grids.
