Jobs in growing: who works in this field
How many people does it take to grow one salad?
More than you might think. A whole team works behind every leaf.
Who keeps a farm like this running?
At a school play, you see the actors. Backstage, a whole crew runs the lights, sound, and sets.
A salad has a backstage crew, too.
Growers care for the plants. They plant seeds, check the plants, and pick the crop.
Many farms start tiny plants in a separate seedling area.
Plant scientists look for better ways to grow crops.
They run tests and measure what happens.
On farms with fish, some workers care for the fish. They feed the fish and keep them healthy.
They test the water often and keep it clean.
Engineers design the pumps, lights, and buildings.
They plan how air and water move through the farm.
Small tools in the tanks and air measure things like heat and pH. Each one is called a sensorA small tool that measures something, like heat or pH, and sends the reading to a computer.
See it in the glossary.
Sensors send readings to a screen, so people can watch the whole farm.
Your turn. Who works where?
Match each job to its station on the farm.
Match each job to a letter.
Tap a letter, then tap its name.
Which name goes with A?
Match each job to a letter.
The answer:
- A · grower Growers start the seeds and care for young plants.
- B · fish and water specialist They keep the fish healthy and the water clean.
- C · engineer Engineers design the lights, racks, and pumps.
- D · sensors and data Readings from the sensors show up on this screen.
- E · plant scientist Scientists test new ideas at the bench.
Teachers share what growers learn. Some, called extension educators, work for universities and teach farmers.
Science, math, and technology all help in jobs in growing.

Which school subjects help with jobs in growing?
Show the answer
Science, math, and technology. Right. Each one helps someone on the farm.
You just learned who works together to grow our food.
You finished the whole course. That's all 4 tracks.

Many more people help grow food. Plant breeders develop new kinds of crops that fight disease or taste better.
Extension educators work for public universities. They answer growers’ questions, run classes and workshops, and show new methods on farms.
On indoor farms, sensors can record temperature, light, pH, and nutrient strength all day and all night.
Engineers for farms often study agricultural and biological engineering. Their classes cover things like lighting, cooling, and watering systems.
Plant scientists often earn a college degree in a science such as biology or chemistry.
You can practice now. A lettuce jar or a paper aquaponics design uses some of the same skills as these jobs.
