Smart Greenhouse flowchart activity
Teach automation logic with soil moisture, water level, temperature, humidity, ventilation, lighting and watering outputs.
Concepts taught
This model helps students practise sequence, selection, conditionals, branching, iteration, repetition, loops, variables, inputs and outputs in a concrete classroom scenario.
Suggested age or phase
Primary/elementary extension, middle school, secondary/high school and GCSE variables practice.
Learning objectives
- Identify the physical inputs and outputs in the system.
- Build a flowchart that uses decisions and repeated checks.
- Trace what happens when conditions change.
- Explain how the algorithm could be converted into pseudocode or code.
Example tasks
Task 1: Manual watering test
Students build and run a flowchart that applies sequence, decisions and repeated checks in the Smart Greenhouse model.
Task 2: Soil moisture watering
Students build and run a flowchart that applies sequence, decisions and repeated checks in the Smart Greenhouse model.
Task 3: Tank-low warning
Students build and run a flowchart that applies sequence, decisions and repeated checks in the Smart Greenhouse model.
Task 4: Temperature ventilation
Students build and run a flowchart that applies sequence, decisions and repeated checks in the Smart Greenhouse model.
Task 5: Full climate control
Students build and run a flowchart that applies sequence, decisions and repeated checks in the Smart Greenhouse model.
Common misconceptions
- Thinking dry soil is an output rather than an input condition.
- Turning on the pump when the tank is low.
- Missing the repeated sensor check after each action.
Curriculum connections
Useful for England computing lessons on sequence, selection and repetition; Australian curriculum language such as branching and iteration; and US K-12 computer science vocabulary including loops, conditionals, algorithms and flowcharts.
Teachers can use the activity as a starter, live demonstration, independent task, intervention activity or assessment checkpoint.
