Get outside and test soil sample for their pH while learning fundamental science concepts in the environment!
Location: SEEDS, 706 Gilbert St, Durham
Our mission is packed into a fast-paced 90-minute investigation, transforming the garden into a living dataset:
Participants will investigate soil as a measurable system, with emphasis on pH and spatial patterning.
Part 1: Soil Properties (25 min)
- Identify soil texture (sand, silt, clay) using the ribbon test
- Measure soil pH and understand its role in nutrient availability
Part 2: Field Sampling (35 min)
- Collect samples from distinct zones: garden beds, compost, shaded areas, and compacted paths
- Measure pH and moisture using standard field methods
Part 3: Data Mapping (30 min)
- Plot results on a grid to visualize spatial variation
- Identify patterns (gradients) in soil chemistry across the site
- Use pH as a predictor of plant growth potential
This session focuses on generating and interpreting real environmental data.
