Soil pH Testing Lab | Plant Science Activity | Horticulture Experiment

Help students discover how soil conditions impact plant growth with this hands-on pH testing lab! In this activity, students collect soil samples, create a soil-water mixture, and test pH levels using strips or a digital meter.

Students will:
Collect and label soil samples from different locations
Create a soil slurry for accurate testing
Test and analyze pH levels (acidic, neutral, alkaline)
Record observations and compare results
Draw conclusions about how soil affects plant health

This lab builds real-world science skills while connecting directly to gardening, agriculture, and environmental science concepts.

Perfect for:
✔ Horticulture & Agriculture classes
✔ Middle & High School Science
✔ Inquiry-based or lab-centered classrooms

Low prep, engaging, and easy to implement—perfect for getting students thinking like scientists!
