Acid Rain on Plants

Water seedlings with mild vinegar solutions to model acid rain's effect on growth.

The build

Step 01

Mix solutions

Make plain water and weak vinegar mixes.

Step 02

Assign plants

Water each group with one solution.

Step 03

Keep equal

Same light and amounts otherwise.

Step 04

Measure

Track height and health over weeks.

Working Principle

Acidic water stresses roots and leaves, so plants given the vinegar mixes generally grow more slowly than the plain-water control.

The science behind it

A closer look

Acid rain (from pollution) lowers soil pH and damages plants — modelled here with dilute vinegar.

Variables to test

  • 1 Test several acid strengths — a threshold?
  • 2 Does adding crushed chalk (a base) help?
