Establish and Compare Seed-Starting Systems

Adult extension of: Seed Starting Lab & Hydroponic Gardening

March 15–19, 2027 · planned

Start a labeled crop and compare a conventional starter with a prepared hydroponic demonstration using a practical care log.

Curriculum skill focus: Sequencing, comparison, plant care, recording growth

01 · Learning

Objectives

Read the seed and system instructions; identify the crop and expected germination conditions.
Sow or position seeds in the prepared supports at the required depth and spacing.
Assign observation dates and record germination and root development before drawing conclusions.

02 · Preparation

Materials

Approved large seeds and covered alternatives for small seeds; Clean starter containers, moist growing medium, labeled water-growing demonstration; Adult-prepared supports and care chart

03 · Practice

Adult project

1
Read the seed and system instructions; identify the crop and expected germination conditions.
2
Label equal starting dates and choose a comparison that can be observed without promising equal growth.
3
Sow or position seeds in the prepared supports at the required depth and spacing.
4
Document water, light, support, and later nutrient needs for each system; adults prepare any nutrient solution.
5
Assign observation dates and record germination and root development before drawing conclusions.

Evidence & interpretation

What the investigation shows

Seeds germinate when their species-specific conditions are met. Longer-term hydroponic growth requires suitable support, light, oxygen, and mineral nutrients; plain water is not a complete growing plan.

Practical connection

Why this work matters

Practice observation, decision-making, shared responsibilities, and communication through a concrete plant or materials task. Participants choose hands-on, planning, or recording roles.

Participation by choice

Individual access options

Offer speech, pointing, gaze, AAC, partner-assisted scanning, or a recorded choice. Follow individual vision and mobility plans. Present one or two items at a time; watching, declining, and taking a break are valid participation.
Use a seated-height tray, stabilized tools, large-print or picture instructions, and partner assistance chosen by the participant.
Reduce the number of comparisons or complete the planning and observation portions without handling materials.

Review & transfer

Reflect on the work

What does a plant need after its seed reserves are used?
Which differences between the systems might affect the comparison?
