Lesson Objective

Students will evaluate crop options and select plants based on nutrient demand, growth rate, and system compatibility.

What makes a plant suitable for aquaponics?
How does nutrient demand differ across crops?
How does root structure affect water flow?

Leafy greens
Fruiting crops
Nutrient uptake
Harvest cycle
Root mass
Biomass

HS-LS2-1
Factors affecting carrying capacity.

SEP – Engaging in Argument from Evidence

Students compare evidence across categories.
Students justify selection based on constraints.

Day 1 – Crop Research

Students compare growth characteristics.

Day 2 – Compatibility Analysis

Students connect nitrate production to plant demand.

Day 3 – Proposal Submission

Students justify crop selection.

Purpose:
Move from decorative thinking to productive system planning.

DOK 2 – Compare plant characteristics.
DOK 3 – Justify crop choice using system data.

Farmers must match crops to nutrient availability.
Food deserts benefit from fast-growing crops.

Any plant can grow in aquaponics.
Faster growth always equals better outcome.

Provide plant comparison charts.
Offer scaffolded justification template.
